Basically MY first comment was if you've the time any format
is possible.
I know for a fact and have seen MSDOS 2.11 running on S100
crates with mixed drives (both 5.25 and 8") using nothing
but serial lines (no monitors).
Used to be a time where you could buy the programmers kit
and customize MSDOS just like CP/M-80. Then MS decided
they didn't want that.

We've already seen this poat and the traffic resulting.
The M8189 used an odd motorola 8K part for MSCP boot not 2716.

I've just received images of the Cromemco SCC ROMs
(Z80 Monitor and 3K BASIC) which I know a number of
people have been looking for for some time.
I've already got them posted to my local copy of my site,
and will move this to the live site sometime this morning.
Should be available by noon (EST).
Site URL is in my sig below, click on the "S-100" heading
near the top, which will take you to my S-100 cards page.
Scroll down to the Cromemco section and find the SCC
entry. By noon there should be a "[ROM IMAGES]" link
there.
Regards,
Dave

I have MSdos on 8" unknown format but likely something native to a
Compupro DISK1A with a CPU85/88 as the engine. I also have a two
edition article describing what it would take to put MSDOS (V3.3!)
on a NON-PC 8088 system.
Supporting 8" is not hard you need 250 and 500khz data rates
same as 5.25 360k and 3.5" 720k formats.

RE: "I have heard of (but not seen) machines with 8" floppies that run
MS-DOS 1.x (not real sure what version)."
Well, the Heathkit / Zenith Z-100 ran MS-DOS (called Z-DOS -- it was not PC
compatible at the hardware level) and also supported 8" floppy drives (in
fact a very nice accessory external dual-drive 8" floppy was offered).
Also, again not PC compatible, but the CompuPro (Godbout) systems had 8"
drives and in some configurations ran MS-DOS. Also, the Seattle Computer
Products systems. And there were 8" controllers for early PCs.

I only discovered it recently. I'd almost given up using it, for all
the reaons you gave. As I see it, Google itself is easy to use, gives
you the information you want by and large, in a sensible presentation.
Google Groups doesn't fare well by comparison, so I use it
infrequently.
> well, I stand corrected. I might have to start liking Google again :)
I wouldn't go that far :-) I said it "mostly" works. And the
interface and layout still sucks.

I just thought I'd let y'all know that anyone who doesn't have an EPROM
burner that can burn 68764/6 chips, I do, so if you need 'em erased &
programmed, I can do that as well... if you send me Intel Hex or S-record
format files.
(The software can do binary files, but I don't trust email for not munging
it... ;-)
By far the "hardest" (read: time-consuming) work is extracting the chips
>from the carriers...
I'll see what I have directly at hand (read: without needing to dig 'round
the attic) for '66s and email y'all tonite or first thing tomorrow.
I'm cheap, no minimum order, I throw extras in for free (if you order 2,
you'll get 4 "just in case" ;-) I take paypal or if you can get away with
it, foreign to the US coin/currency (usually at a great discount - I've
collected coins longer than computers, and I have a pretty decent foreign
collection, especially for a dumbass American!

Hi,
I've just purchased a second hand 3Com CS2600 terminal server, but it was
sold without its software does anyone have a spare, unloved copy of the
Multiprotocol Communications Server software? 3Com are only interested if
you have a pre-exisiting service contract :(
Thanks
Jim.

You got it. Although to be fair, it does look nicer than "flat"
buttons. Frankly, it's that big an innovation though. 3D buttons were
in OpenGEM 3 and were taken out from version 4 as the implementation
as of 2003 or so meant that it took up too much memory. Clearly they
either fixed the memory problem or just don't care anymore.
