[M100] QUAD

[Frederick Whitaker]

I know that many of you have had strange experiences with QUAD and REX 
when used together, especially if you used the OQUAD program.


I have only high praise for the QUAD. It is not only an excellent way to 
expand the memory on a Tandy Model 100, it provides four screens of 32K 
memory which can easily be accessed using a four line basic program.


Because of your comments Stephen Adolph attempted to add screen access 
to the REX, and did so in one version of the software. As he has refined 
the REX software it has become more and more difficult to keep that 
function. Because of time constraints he has turned to other projects.


The QUAD is a tremendous achievement which should not be allowed to go away.

Re: [M100] Dust Covers

[Frederick Whitaker]

I was wondering why cloth dust covers haven't been considered. It is a 
lot easier to make one out of cloth, and tends to be more durable. 
Plastic has a way of not lasting as long as you would like, especially 
the thinner clear plastic.

unfortunately cannot part with it -- it is currently protecting my

I don't know of any other places that manufacture them. This may be a

Re: [M100] List of wanna haves

[Frederick Whitaker]

I remember the club members wanting to expand the Model 100's so that it 
can work more efficiently, and provide externals that assist in doing 
that. The DVI made it a little like a desktop computer. The external 
Disk Drives made it possible to store files on disks so that they could 
be accessed later.


In recent years the REX, NADSBOX, Quattro, and other things have appeared.

What fascinates me about the projects that are being suggested today is 
that they are way beyond the innate capacity of the Model "T". Why are 
we not writing programs for the Model "T" anymore? Why are we trying to 
mimic the contemporary Desk Top Computer? Why are we not writing 
assembly programs for it?


I get the idea that many of the club members see it as a novelty, rather 
than a genuine computer. It was the first of its kind. For many years it 
was used to write newspaper articles and send them over the phone lines 
to the publisher. It was used for controlling devices; like entry gates, 
lights, and other things. Until recently it was used for controlling 
traffic lights in Greenville, South Carolina. It is a genuine computer.


Are we not interested in writing programs for it anymore? Do we only 
take it out to write an article, or take notes? Is it no longer 
interesting in itself?


I miss DOS, and command line Linux, but I no longer have machines that 
give me access to DOS, and with all the programs already available for 
Linux I am no longer motivated to work at the command level.


It is noteworthy that there is still interest in the Model "T", but more 
work could be accomplished if each of us stuck with one project at a 
time. I miss Dave?

[M100] Hard cover for the Model 100!

Since at least one is custom firmware it's probably in an EPROM (as opposed to

 From what I've read it looks like there should be three 28-pin sockets with a

I recently found an Olivetti M10 in a flea market. Despite the
exterior really good condition the M10 initially worked randomly
(sometimes I had to reset it). In these latest days the M10 normally
freezes (clock stops and any action is prevented) or shows a scrambled
text on display. You can find the scrambled display problem picture
here: 
http://s346.photobucket.com/user/brazoai1/media/WP_20160725_21_27_30_Pro_zpsdxbgksae.jpg.html.

Sometimes, when it doesn't freeze after boot, I can access BASIC, but
any command (even the simplest one) produce a system error or freeze
the M10 again.

The first times the problem showed up I removed the BASIC ROM and
cleaned it with a dry contact cleaner (something like G-20), the RAM
and EPROM chips seems to be soldered and I didn't try to force remove
them to clean. The M10 shows no internal damages, previous batteries
didn't leak and the NiCd seems to be in good condition and charged.

Is there any advice or "check procedure" I can try before to embrace my welder?

Thanks in advance,

RBASIC is still an excellent tool. Unless someone would like to develop

they have to be run under a Z80 emulator.

Re: [M100] DISK+ ROM but no floppy for PC side

[Frederick Whitaker]

According to the Disk+ manual, using the files on the Disk it is 
possible to transfer any type of file from the Model 100 to the storage 
disk, but only if the files on the Disk are on the external drive.
Disk+ loads the external file to use in the manipulation of the files on 
the storage media. The ROM is only half of the program.


It would be good if these files, and a ROM image of Disk+ could be 
uploaded to the Club100 web site.
