[cctalk] MS-DOS

[Murray McCullough via cctalk]

I had not realized that 43 yrs. ago Microsoft purchased 86-DOS for $50,000
– US not Cdn. money. With this purchase the PC industry, IBM’s version
thereof, began. I remember using it to do amazing things, moreso than what
8-bit machines could do!

Happy computing.

I came across this today: “Electronics engineer builds 1986 Macintosh Plus

I, as a history-researcher, relied on computer magazines from the early

Hardware is another issue!

[cctalk] L. Conway

[Murray McCullough via cctalk]

Today I came across an obituary of Lynn Conway, computer pioneer in the
field of VLSI(along with Carver Mead) and also in one called dynamic
instruction scheduling(used in supercomputing world). More to the point
Conway was transgender and suffered for this, an almost forgotten pioneer
in the microcomputing and supercomputing fields. Also, as a researcher at
IBM and Xerox Parc where she contributed to the first years of
microcomputing, the GUI and Ethernet protocol development. Eventually the
IEEE recognized her contributions as did IBM - better late than never!

[cctalk] Re: Intel 8086 - 46 yrs. ago

[Murray McCullough via cctalk]

I agree that parallelism, or more accurately multiprocessing, has
contributed a great deal to the advancement of 8086 technology. So to has
speed: The first 8086 was clocked at 5Mhz.; now the speed is 6Ghz. The
shrinkage of computer components in ULSIC technology has made this
possible. But today I believe we're nearing an end to 8086 CISC technology
because its science and technology will only take it so far.

It appears that one can determine what is a personal and/or a microcomputer
that satisfies only the author.  If one states that and believes it then
that is all that’s necessary. I wrote a book based on this line of thinking
and if a reader disagrees with me that is fine. I’m not declaring the true
and only way as the means to change anyone’s view. I wrote it to give a
background on the history of the microcomputer that may or may not be the
whole truth.

It appears that  I am  in error. I see that micro-electronics or something

I quite agree. I do believe that a *u*P is the minimum that can be accepted
to call a PC a microcomputer. Another is that it must be usable, i.e.,
non-programmable, for the average PC owner. Like a car one doesn't need to
know how it works in order to drive/use a car to get from one place to
another. One can use a computer to solve a spreadsheet problem in an
efficient manner without learning the inner-workings of such spreadsheet.

The MCM/70 was a Canadian invention though not certain it was a 'first' in
the microcomputer world. Some say the Kenbak 1 was. The Altair 8800, as I
argue, the first to reach a large audience. It demonstrated what was
possible to non-computer people.

[cctalk] CP/M

[Murray McCullough via cctalk]

I came across an article that said CP/M came out in April 1974. I remember
using this OS in the microcomputer world in the late 70’s; early 80’s. It
came from PL/M, (Programming Language for Microcomputers) later renamed
CP/M(Control Program for Microcomputers). I’m not sure what its legacy is
though as far as I can recall it was wrapped up in litigation for quite
some time. It was used in the 8-bit world but not sure what it's role was
in the early PC world!

[cctalk] Re: APL (Was: BASIC

[Murray McCullough via cctalk]

I’m not certain what constitutes the original foundations of
BASIC(Beginner’s All-Purpose Symbolic Instruction Code) but to my knowledge
it began with J. G. Kemeny and T. E. Kurtz at Dartmouth College in 1964.
Apple BASIC and GWBASIC were well established when I began experimenting
with them in early 1980’s. By mid-80’s I was running both on a PC and
Coleco ADAM. I wrote a program using GWBASIC for cataloging my books and
magazines.

[cctalk] BASIC

[Murray McCullough via cctalk]

Nostalgia keeps pressing ahead: It was 60 yrs. ago that BASIC came into
existence. I remember very well writing in Apple Basic and GW Basic later
on. As a non-compiled OS, an interpreted OS, it was just the right tool for
a microcomputer with  limited memory. I recall fondly taking code from
popular magazines and getting them to run. It was thrilling indeed!

[cctalk] Re: Altair 8800 50th birthday...

[Murray McCullough via cctalk]

The Altair 8800 used a microprocessor, the 8080, and came to public
prominence in Jan. 1975 in Popular Electronics magazine: "World's First
Minicomptuer Kit to Rival Commercial Models."  I have the original magazine
from that era and I remember this quite well as it brought attention to a
mass-consumer audience  - a device called a microcomputer though not what
PE called it! Here in Canada the price was very expensive but I had a dear
friend, an electronics engineer, who purchased one. It was very limited,
hardware and software-wise, and my friend found it a ‘nightmare’ to build
but what a momentous reward when it finally worked. To this 23 year-old it
certainly sparked my interest with what we now call classical computing.

Happy computing all. 

An excellent trip down memory lane. I no longer have the memory and

remember and cherish. The first computer I remember working on was the
either the PDP-7 or 8(classmates at that time no longer live here in rural
Ontario to consult with) at my high-school where the electronics/electrical
teacher had in his office. It was a donation from a wealthy benefactor, an

[cctalk] The 8008

[Murray McCullough via cctalk]

I’ve read with great interest, over the past short while, a few interesting
articles on the history of the Intel 8008(officially released in April
1972) as it was the forerunner of what was to become the personal computer
industry. And done with less than 4000 transistors. I saw one at a computer
shop/store in Toronto in the latter 1970s’ but had no idea the seminal role
it was to play in microcomputer history.

[cctalk] IBM PC-XT

[Murray McCullough via cctalk]

I look back fondly on the IBM PC-XT of 41 years ago. It was very pricy here
in the Great North but it allowed for a much more advanced computing
environment. What one could do with a 10MB hard disk! Granted it was far
more popular in the business world than the consumer one. However, it made
possible much greater developments that hobbyists and experimenters latched
onto.

[cctalk] Re: The MAC at 40

[Murray McCullough via cctalk]

I know a great deal of writings by techno-historians, computer-industry
experts and technology enthusiasts concerning the Apple Mac, and now 40
years old, have covered this topic both on and off the net.  Unlike
originally stated I now feel that the MAC was an important change agent in
regards to the all-in-one computer landscape. Why Apple priced it
‘prohibitively’ high, particularly so here in Canada, I’m not sure.
Arguments such as an integrated ecosystem to securing a marketing and brand
loyalty come to mind. Certainly applies to the world of Apple doesn't it!
What I remember most from that time though was their 1984 Super Bowl
commercial! It went a long way to putting Apple and the microcomputer
industry on the mass-consumer market.

The Apple Mac, 40 years old, came from Xerox PARC’s GUI and Apple’s LISA.
Not sure that it really changed computing though! Financially it didn't

[cctalk] Intel 4004

[Murray McCullough via cctalk]

On Nov. 15, 1971 Intel commercially released the 4004 microprocessor which
some consider to be the first. Nonetheless, even if not in agreement, it
made possible the instrument which drives the classic-computing industry or
at the very least our hobby!

[cctalk] Apple 1

[Murray McCullough via cctalk]

Classic computers have a value in our capitalist society. Take the Apple-1:
Its value can be in the $100,000s. One is for sale now: ~ $200,000. Next
seems to be the Kenbak-1 valued somewhere around $50,000. Now, I’m not
suggesting money is the epitome for evaluating our hobby but it goes a long
way to explaining its longevity.

Microcomputing nostalgia & cctalk

[Murray McCullough via cctalk]

  Nostalgia is great for aging baby-boomers as me. Back in 1978 I along
with a friend bought a Heathkit H1 and spent many leisure hours
constructing it and getting it to boot up! By 1984 I moved on to the Coleco
ADAM and learned BASIC(Well more accurately APPLE Basic) spending too much
time on it rather than on my PhD studies. Trying to write my dissertation
using Writer was a challenge as was getting it to print on the included
daisy-wheel printer – all that clacking. Noise! Noise! as the Grinch says.  But
I did get my doctorate but had to go to S. Korea and Univ. of
Education(TESOL program) to use it.



  Microsoft’s monopoly began in the earliest days of microcomputing. Read
Gate’s letter to programmers /hobbyists to see how a monopolist thinks.
Linux has come along and poked Microsoft in the eye but hasn’t done too
much damage according to this writer. As written here a nostalgia for the
early years may be what we classic computer-philes find so compelling in
cctalk. And to be honest I’ll move to WIN 11 because the choice(s) are
somewhat limited.

our relationship though.

  In the past I have run both WIN and Linux on my machine – a dual-boot

things better than Windows particularly when I run an emulator(It is based
on a Coleco ADAM I’ve had since1984.)

To my knowledge the Linux kernel was released to the public 30 years ago

Windows even though WIN 11 is much more secure than previous Windows

for 8-bit and 16-bit machines we classic computer users could use. For
emulators now we have a choice but do they work better in Linux or Windows?

be 5040 shares after 5 splits. Its price today is $121/share. That would be
$609,840. Here in Canada that’s $939,153! Quite the nest egg. It has
certainly paid quite handsomely to have invested in Classic Computers or in
one company back then.

I agree that using ‘*first**’* has a certain connotation. However, until it

Re: GWBASIC Source Code

[Murray McCullough via cctalk]

  GWBASIC- (Gee-Whiz BASIC) is a Microsoft product, designed much along the
line of IBM’s BASICA, that did not need a ROM BASIC and was interpreted.
Not necessarily basic in design or purpose as defined by Oxford English
Dictionary & Wikipedia and Computer Desktop Encyclopedia, some(purists) say
the latter two shouldn’t be used with the former, GWBASIC nevertheless was
an important development in the early years of our hobby. Little has been
mentioned about the source code:
https://devblogs.microsoft.com/commandline/microsoft-open-sources-gw-basic/

It’s available on GitHub for download and use in WIN 7 to 10 as far as I
know!



  At that time(1983) in micro-computing history it did what was intended,
help microcomputer owners/users with limited processor and memory
capabilities. Serving this purpose, was there a better BASIC? No doubt. I
used ADAM-BASIC, much like APPLE BASIC, to write silly-little programs or
more-sophisticated ones. Hobbyists, experimenters and early microcomputer
lovers had another tool to master. It’s success may be attributed more to
marketing than anything else but early microcomputer users were happy to
get their hands on something new. And, Microsoft knew marketing, not as
well as APPLE, but the game was capitalism and getting software out the
door! Being first or second was not necessarily the primary reason for
rising to the top. And today: Is LOGO or Python any better teaching tools
than GWBASIC for beginners? I hardly doubt that.

  Things we historians talk about are ‘firsts’ and ‘facts’. If we go to

that can be said is we agree to disagree. A sad commentary in this age of
what my ‘facts’ and your ‘facts’ are, are not the same but we historians
should do our best to state ‘firsts’ and ‘facts’ are indeed that to the

spent years as a BASIC, C and C++ programmer as isn’t mathematics the basis
for all programming languages? Let's indeed toast to all micro-computing
progenitors for making our hobby possible.



  I’ve been a hobbyist and experimenter since the 1970s though I worked on
mini-computers(PDP-8/11) in the 1960s. I got to work on them in high
school; I know we were rather privileged.



  For microcomputers it began in April 1978 when I built the Heathkit
H8($2500 Cdn.) a computer based on the PDP-11 with 4K(B) of an 8K(B) card;
now $2500 will buy a truly powerful home computer with 16/32GB of memory.
My second, the Coleco ADAM, computer was Aug. 1984. A bit more powerful and
more useful to be sure. Finally in 1989 I moved into the IBM PC world – the
Compaq Deskpro 386 which ran DOS, Lotus 1-2-3 and Windows 2 that could run
Word and Excel. Wow! Notebooks followed.



  And now(well Aug. 2019 to be precise) I built my own custom Mini-ITX PC
from parts sourced here and there for $750 Cdn. This makes me nostalgic for
the old days of computing we talk about on cctalk.

$600. How quaint! BTW(sorry), it had an update on CP/M called CP/M Plus.
Gosh, I miss those old days.

Happy computing all.

Re: Pioneers of computing

[Murray McCullough via cctalk]

Thanks for the info on chip made by Texas Instruments. It was used in a
pocket/plug-in calculator I had while working as a payroll clerk back in
the early 70s.



The link is: http://www.vintagecalculators.com/html/ti_cal-tech1.html



I’ve written in my book on the History of the Microcomputer a history of
the processing chip as the timeline follows an approximation of:



Late *1950*s – patent on integrated circuit by Texas Instruments


*1950*s to *1960*s – move from vacuum tubes to TTL technology

  programs/functions in ROM



*1970*s – 4004 to 8008 to 8086  -> This begins the era of electronic
computerization of society.

->  programmable by user and/or firmware


We are now in the early human era of the electronification-computerization
of society. *Classic Computing* takes us back to the very early years.


Happy computing!

Pioneers of computing

[Murray McCullough via cctalk]

Back in 1965 Jack Kilby, Jerry Merryman and James Van Tassel at texas
Instruments created an integrated circuit designed to replace the
calulator. Historians, though not all, credit this development as the
beginning of the electronic-computing revolution that was truly underway by
the mid-70s. Vintage/classic computing our hobby goes back that far as us
baby-boomers can attest to.

Happy computing all!

Speed now & then

[Murray McCullough via cctalk]

I’m not trying to date myself but have things truly sped up? In 1970’s
Toronto I had a classic computer, sorry can’t recall what it was, connected
to a 300 baud modem; by early 80’s had ‘zoomed’ to 9600 baud. Oh, my! [ A
typical file size to download was probably 1 MB. ] Speed indeed! Yet now,
here in rural Ontario, Canada, I’m at 5MB/s. Yikes! (Friends in Toronto are
at 50MB/s.) We can do the math but content, particularly multimedia, has
swollen in size.[ 1 GB is not unheard of. ] Were classic computing days
that much slower? Happy computing. Murray  -:)

Modems & Xerox

[Murray McCullough via cctalk]

I started accessing BBSs back in the early 70s with a 300 baud modem.
>From there it went to 1200; 2400; 9600; 28.8K and 56Kilobaud. All on
dialup! Now at 5 Mbits/sec. here in Ontario. An American friend has
250Mb/s download. Yikes!  The classic computer era taught us patience
didn’t it? BTW, one had to have a private phone line not a party line
for a modem to work. Making our hobby more expensive!

On the business-side of computing: Xerox sold 50.1% of its business to
Fujifilm, Japan. Xerox Parc was a seminal institution in early classic
computing era: Mouse and graphics input for instance.

Happy computing!

3 computing events

[Murray McCullough via cctalk]

Three ‘computing’ events are happening:



1)  The i-Pad was introduced by S. Jobs 8 yrs. ago and defined a ‘new’
computing paradigm for the masses. The reason I mention this event is
because a young friend(20 yrs. old) said “That’s ancient computing!” What
is one to make of classic-computing then?



2)  Bitcoin mining – The energy usage is extreme because of GPUs. Was
16-bit computer era, employing the 80287, such an energy hog?



3)  INTEL doesn’t seem to have been hurt by Meltdown & Specture
financially- speaking. Had excellent earnings and profits for the last
quarter but ‘may’ change this quarter. However, INTEL marches on going from
4004 to 7980XE. AMD was/in the picture but financially-wise…



Happy computing all!

Spectre & Meltdown

[Murray McCullough via cctalk]

I wrote about Spectre and Meltdown recently: INTEL took its time to inform
the world! Did it inform the world back in earlier days about potential
flaws? Not to blame INTEL only: What about Zilog, etc.? Or did pre-Internet
era protect us computer-classic users? What about running emulation
software as I’ve been doing with ADAM?



Happy computing!

Spectre & Meltdown

[Murray McCullough via cctalk]

This may be off-topic but these latest uprocessor exploits has raised
a question: Are the 'old/classic' uprocessors using x86 technology in
the same boat? The very earliest ones, i.e., 1970s and early 80's.
probably not. How many are actually in use and/or on the Net?

Happy computing!

Computing from 1976

[Murray McCullough via cctalk]

I was perusing my old computer magazine collection the other day and
came across an article entitled: “Fast-Growing new hobby, Real
Computers you assemble yourself”, Dec. 1976. It was about MITS,
Sphere, IMSAI and SWT. 4K memory was $500. Yikes! Even more here in
Canada. Now this is true Classic Computing. Have a Happy New Year
everyone. May the computing gods shine down on us all in 2018.

Happy computing.  Murray  :)

Apparently this opinion is fairly widely shared:

"As far as comuters (should it not be computers) were concerned." I
guess one is entitled to their opinion. As an historian of modern
technology and a subset of it, social media, I can only conclude that
the Net allows one to say what they want and have many 'thousands'
concur/agree.

Happy computing all!

[Murray McCullough via cctalk]

Was Jerry Pournelle the FIRST to write a PUBLISHED NOVEL on a
MICROCOMPUTER? Yikes! Talk about SHOUTING. As a historian is it worth
the aggravation to please everyone? Does revisionism take away the
honour(Cdn. Here!) Jerry Pournelle rightly deserves for pioneering
work in our beloved computing genre? Are the passing of our early
microcomputing pioneers
leaving a hole in our history?
