Hi
You need to look a little more. You should find other files
that may be named incorrectly as *.z8k. Some of these are
actually source files and not executables. Most of the assembly
source were called *.8kn. Also, many of the files have some
garble at there ends. This was because of the extraction process.
If you look at them carefully, you'll see that the text starts
to repeat it self at some point. Just delete the repeated
text to the end. I may have these files in PC file format
after they have been cleaned up.
I have gone through the process of starting with the source
files for the BIOS and actually creating a new BIOS. I was
careful to make sure that it ended up matching the original
release image. In anycase, with new BIOS code, I should be able
to build another new image. This would be much easier than
starting from scratch. When you get done, you'd be able to
use the C compiler and assembler that came with this release.
I'll go back and see, just which files I used so that you
can use the matching ones. There were several different
source pieces to hunt through. Some of them were older versions.
The 1.1 stuff is actually the most current. The other revs seem
to be pre-release stuff.

a more complete set of source. I still have no Z8000 C compiler or assembler but
you do, so I might look into this a little more vigorously.

Hi Dwight,

Hi David
It may not be as hard as you'd think. First, you don't have
to cross compile CPM-8000. There already is a CPM-8000. Recently,
source and release code was found for this and, working with Chris
Groessle, we've managed to bring it up on our Olivetti M20's.
This code was originally written for the M20, as it was the only
major machine sold with a Z8000 ( there were a few SBC's out there ).
The release comes with a C compiler and an assembler. There is
source code for the BIOS as well. It does depend on the M20
ROM code for low level access. This CPM was mostly written by
a combination of Zilog and DR people. It is mostly written in
C with a minimum written in assembly.
There are a few issues. Even though the manual says you can get by
with only 128K, this would be difficult. Several of the utilities
require two 64K chunks ( one for instruction and one for data ).
It would be best if the other system functions had there own piece
of RAM to work in. One needs to map the memory such that you can
access a single 64K as both instruction and data as well as
the 128K as 64k instruction and 64k data.
The bad news is that we don't have the complete source for the
CPM. The BIOS does require that it be compiled on a running CPM-8000.
As the documents state, it would be difficult to build it on
some other system. Still if someone is willing to write a BIOS
for their board, I'd be willing to compile the code for them on
my machine.

Hi Everyone,
I have a couple of old systems some of you might be interested in. The first
one is a Vector. This is an all in on unit running CPM as the OS. I only
have the system for this one.
The second is an old Commodore SX-64. For those who don't know it, it is a
small portable Commodore 64. It had a small (maybe 5" diagonal) color crt
and 5 1/4" disk drive internal. I have many additional peripherals for it
including additional 5 1/4" drive, 20MB HD, Memory expansion model (256k),
mouse, GEOS OS, HearSay 2000 (speech recognition and speech module) and lots
of software. It is in 100% working condition and has been well cared for. If
you have any questions about these or other systems please feel free to ask.

Figured I'd ask before I put a lot of time into sorting the thing out the
hard way. <G>
Anyone have the pinouts for an EECO TES-9301 8 level punched tape
reader/spooler?
I expect parallel with status and control lines, but like many critters it
comes out on a DB25 connector and I have no docs on it...
Thanks;

Hi,
I just received an M7847 16KWord memory card for my PDP-11/10. But I
can't find any settings for the switches on it. Any one have any
documentation?
Thanks.

Hello, all:
Does anyone have a spare copy of this that they can part with? I
have most of the info spread over several different help files but I
sometimes find it helpful to have the relatively compact original handy.
Please contact me off-list. Thanks.

Hi
It sounds like something is wrong. Are you reading with BASIC
or at code level. I would think that assembly code should be able
to keep up, as long as you were not expecting it to transfer to
disk while reading. Does the M200 have any kind of handshake?

Hi
I thought you were using the pin as an input. As an input,
there is no pullup and a floating pin would not be good.

I have an ATT 6300 with 640 kb ram, msdos 3.30 keyboard and monitor in working condition. The keys need some prompting but a good cleaning will probably work. I will only sell as a set.

Hi people. I'm looking for the chassis to a PS/2 Server 95. Not a 95XP,
but a 95A. The one with the longer connector plate and two parallel
ports. I'd prefer if it was somewhere in the northeastern U.S. The New
York area would be optimal. If you want, you can have the PC Server 500
chassis from which I am borrowing the motherboard.
Another thing is that I need the people who were interested in the PS/2
100Mbps ethernet cards to email me again. I now am able to send them out.
$50+shipping apiece.
The third thing is that I am looking for 8MB SIMM's for a PS/2 Model 95.
They are the ECC kind.
Fourth, I am getting rid of a lot of PS/2 SCSI cards, 286 RAM Expansion
cards with RAM, and a couple of 386 RAM Expansion cards with RAM. I also
have a couple of other weird MCA cards, so if there's anything in
particular you're looking for, let me know. I do have a couple of IBM
M-Motion Video Capture Adapter/A's *new in box*, if you're interested.
That should be it.
Peace... Sridhar
