You never know until you try.

Anyway, the Alphaserver 4100 has four midsize muffin fans and I found them 
trivial to take apart and trivial to replace the bearings which were a 
standard off the shelf part.  It was easier to fix the fan than it was to 
replace them since DEC had a custom fan with a speed sensor built in that 
proved impossible for me to find.


It changes from model to model and generation to generation.

Anyway, I was thinking about the little 4" boxer fans, which 
a DS10L may not have.  A number of mid-size and larger Vax 
and Alpha systems had blowers made by EBM-Papst.  It might 
be harder to get these opened, they were not meant to be 
repairable.  The bearings are almost certainly ball bearing, 
so if you can get it apart without breaking the impeller, 
you should be able to press the bearings off the shaft and 
new ones on.
It is probably not a job to be done with the simplest of 
hand tools, however.


I've used a few of these blowers in some of my projects, but 
never had them get noisy.

Unix? Probably a complete brain fart by me - but I thought Unix
required a machine with separate I/D spaces and the 11/40 wasn't one
of them?

If I'm wrong that will be of some assistance to me actually :-)


The early Unix most definitely could run without separate 
I/D spaces, in fact I think it could run without memory 
management. That might have required it to stay in 
single-user mode.  I'm PRETTY sure I ran a Bell Labs Unix on 
an 11 BEFORE we got our 11/45, and those did not have memory 
management.  (11/05 and CalData).  Our tests with that Unix 
did not look promising, so we just did some testing and then 
went to RSX-11M.

Ah, thanks for that. Starting to look at the code, I had missed the
interleave.

So does DEC do anything with track 0, or is it always just empty?

Noel


Track 0 is not used by standard DEC software, block zero of the device (boot 
block)
starts at track 1 sector 1. Track 0 is not even accessible thru the standard 
drivers.


Applies to both PDP-11 (eg, XXDP, RT11) and PDP-8 (OS8).

Maybe specific software that reads/writes disks in IBM exchange mode accesses
track 0, but I've never used such s/w and am only guessing.

A 128K pdp 11/40 should be able to with memory mgt, I thought this was one

Yup, I do this quite often.  I keep a pile of empty jackets around for
just such a purpose.  Very useful in cases where the lining of the
jacket has become contaminated with dirt or spilled liquids.

Just slit or cut the top edge of the jacket for easy removal/insertion.

Much has been imaged and is over in bitsavers.org...  Software stride

What it requires is a Real Computer(tm) with disk drives not one of the
latest octa-core Vunderkind M$ PCs.

An older box with a FD55GFV and one of the better 3.5" should handle all
but 8" and hard sector needs.
I keep a Dell 486 powered pizza box for that as it has all the 5.25 and
3.5 capability, for an OS winders3.11
is fine as its really DOS and moderately useful as it runs teledisk
still.   Also the smaller pentium box with
linux as its got that as well.   Either than or a CP/M-80 machine with a
bunch of drives, MY s100 crate
has that from 8 though 3.5.A Qbus pdp-11 with the full compliment of
floppies from RX02, though
5.25 and 3.5" can do it as well.

You can slit the disks open, and one at a time, put them into a fresh

If the warpage isn't severe, but the disks are just hard to turn, . . .
hold the disk perpendicular to the edge of a table, pushing a little, so

BRL PDP-11 kernels had both V6 and V7 file systems in them but I'd have to

For RX01 (and RX02) the hardware bootstrap reads track 1 sectors 1, 3, 5, 7
into memory. For RX01 with 128B sectors this yields 512B total (just like 
reading
one 512B block from most other disks). Their is a fixed 2:1 sector interleave.

For RX02 is does the same sector reads, but since the sectors are 256B the total
amount of data read is 1024B. In reality only sectors 1, 3 need be read, but the
bootstrap (M9312 anyway) just goes ahead and reads all four sectors always.

It's a Z-80 system. I can't use CP/M-86 on that, can I?

My recollection of 1.25 was that it had foreign language (at lead
code-page type support) where 1.1 did not.  It lasted longer than it
should have.

It sounds like you have a similar system to mine.  I'd expect you to be
able to boot the cpm86 or cpm 86 gg disks.  The one disk that does not

Thanks for sharing! Those images will probably be quite helpful to many folks 
trying to resurrect vintage Compupro hardware, myself included.

One of the links appears to be bad: The filename is "MPM2.1ED", but clicking it 
just leads to the site index page.

Not looking for help, just offering the files to whomever wants to attempt
them.   A disclaimer that these are as-is, good luck.

Re: Compupro Disk Images Uploaded

Simplest test for MS-DOS 1.25 would the the dates of the files, 
particularly IO.SYS and MSDOS.SYS.  IIRC, 1.25 would be in 1982, maybe 
June.

Very true.
When was the earliest that a 1.25 was released to OEMs?

On the other end, 2.00 came out somewhere around march or April 1983.

If the dates are in the right range, then there are other clues, such as 
matching file sizes.


Starting with 2.00? there was a version number buried in the code, and the 
VER command would print some text, and then calculate what to display for 
the numbers (major version, period, minor version as a 2 digit decimal 
number.0 (19h gave .25)
But, if 1.25 didn't have that, then somewhere in COMMAND.COM, there might 
be text saying "MS-DOS 1.25", instead of the later ""MS-DOS ", to be 
followed by calculated values.

Did 1.25 have ANSI.SYS and CONFIG.SYS?

For somebody who remembers the detaails of the transition, many of the 
text messages in COMMAND.COM might be recognizable.

Just to clarify, I meant the plastic floppy disk case when I said “sleeve".

1.25 was licensed for OEM customization for quite some time, so dates
could well be later, depending on the OEM.

RE: [TUHS] Booting PDP-11's from RX02's

[Ron Natalie]

I think just like everything else the boot rom just pulls in the first
sector of the disk.   I had RX02s on many of the BRL Gateways (my
implementation that replaced your MIT Gateway while you were in exile).
We put a V6 file system and I must have had a regular V6 boot block on it
with a RX02.   There might be someone still at BRL who might remember where
this stuff is.   I certainly don't have it.

BRL PDP-11 kernels had both V6 and V7 file systems in them but I'd have to
believe I was booting off a V6 one.

Compupro Disk Images Uploaded

[william degnan]

I have uploaded a set of disk images from My Compupro system with an 8085
and 8086 card, plus regular z80.  The thread starts a number of years ago,
but today I just updated, at the bottom, to include images of the disks I
have for the system.

Some interesting concurrent CPM and DOS stuff, not sure if this is really
MS DOS 1.25 or not, never got it to work on my system.  I'd love to see
someone else make it work.

Thread:
http://vintagecomputer.net/browse_thread.cfm?id=265

Just get the IMD images:

As always, thanks Dave Dunfield, please use the images with the proper

Imaging Old Disks Advice Needed

[Peter Cetinski]

I’ve recently acquired a rare complete set of 10 TRS-XENIX 1.0 Development 
System floppy disks.  I’ve done quite a bit of 8” disk imaging so I'm fairly 
comfortable using ImageDisk, cleaning disk heads, etc.  I’ve run into a 
scenario with these disks that I have not had to deal with before.  Since this 
is the only complete set of this software I’ve ever seen, I need to be really 
careful with how I proceed.  The media itself looks pretty good.  No scratches, 
no blotches.  However, on a number of disks the sleeves have warped.  I am 
afraid that this will damage the media when I spin them up.  I’m thinking of 
cutting open the sleeves and placing the media in new 8” floppy sleeves.  I’ve 
also heard about baking the media, although I’ve never tried this and not sure 
of its value.  

What are your thoughts on how to proceed?
