Already on this one...picking it up 10/3. I found out about it through my
contact at Temple University.

Sounds like an early Datamaster to me. I have a Datamaster (5123), but it has
a green-screen, not a B&W one. Otherwise the description matches.
As I understand the Datamaster, it really was the predecessor to the PC. It
was desktop based, although you needed a large desk <g>. It had an ISA-like
bus into which you could plug-in cards. My guess, from talking to someone who
worked on the project, that it was a business machine (A/P, billing, word
processing, etc.) that fell out of favor when IBM introduced the PC in 1981.
The PC was 1/3 the size, probably 1/4 the weight, much faster, and used 5-1/4"
diskettes.
There are several Datamaster owners here who can fill in more about the
actual specs. I don't use mine much because I have a blown ROM chip that
prevents me from booting...

I have a 5110 cpu unit but had to leave the drive unit and printer behind :(
If you can get the 5120 it would be a great find for your collection. The
data storage could be either 1.2 M or 2.4 M on the 8" floppies. The machine
was announced in March of 1980 and was the successor to the 5100 and was
based on the 5110 Model 3. Also Basic and APL are in ROM. Good luck with it.

In a message dated 97-09-17 21:37:24 EDT, Mr Clifton put forth:
<< Received some fun free things today. I got an IBM Convertible that works
but appears to have no ports for things like printers, serial, etc. What
info can anyone give me about this machine and does anyone have the

I also have a pc convertible. pretty neat little machine. it had nothing
built-in except for a modem, or at least mine does. ports were added by means
on "wedges" you plugged in at the back of the machine. I have the
serial/parallel adaptor as well as some kind of rca output video and pcjr
style video output plugs. recently i just picked up the pc convertible
printer that also attached to the back of the machine. my battery is bad, and
my ac adaptor is dodgy so i need to fix that before i can really play with
it. when everything is plugged in, the whole setup is about twice a long as
normal, certainly doesnt fit on a desk well. I have the guide to operations,
as well as extra floppy drives and a spare lcd. I can provide addtional info
if need be.

I've got one of these too - beautiful computers, wonderfully engineered.

Always check for this. A very common problem is that the batteries corrode
and kill the motherboard.

Are you running it as a Mac XL or as a Lisa? Again, this is a common
problem with the XL OS, and occurs on mine. Although not wise, I found
switching it off at the power supply was the only solution. It does seem
to work while booting up though - just not while in the OS.

>(the disk is nice and quite, moreso than a lot of more modern drives).
Note that it takes a while for the ProFile to reach operating speed. Until
the red light is on solidly, do not start your Lisa - wait until you get a
solid light before turning it on. That should solve at least some of your
problems.

You should be able to get them, but I am afraid I know not where. However I
had heard that Sun Remarketing had the OS for the Lisa, including the
original Office 7/7, or whatever it was called. You should perhaps contact
them.

Hi everyone
Had a good week so far and picked 8 Mac plus units for those of you who
e-mailed me for one. I will go back and look at the date and time on each
e-mail and contact you in that order to see if you are still interested in a
unit. I also got 2 SE's with the 20 meg HD, one is the SE FDHD unit M5011
Vs the SE M5010 they even look different across the front. Got 2 SE's with
just floppy drives. 2 apple 800k ext FD units M0131;
2 Hayes microcoupler units; 1 SummaSketch unit wit pen and power supply; IBM
8507 19' mono vga unit; Apple extended KBII; Triplet model 601 solid state
v-o-m; 2 digital DECserver100's and 1 model 300 with manuals and software;
CMS ext tape cartridge unit;
EICO oscilloscope model 460; Panasonic video monitor model WV-950; and last
a Catamount Ministreamer magnetic transport tape drie unit model 1052. And
the weekend is not even close for my long trips out to the small towns. I'm
doing my part to save as much as I can from the scrape bin. Keep computing !
There are a number of modules that plug into the PC Convertible. It's
analogous to the PCjr "sidecars". I know that the following units
exist: 1) a serial/parallel module; 2) a composite video output module
for the PC Convertible Monitor; 3) a printer module; and 4) the battery
module.

Please reply direct if you can help.
And no, I couldn't resist the pun. ;-)

I am searching for a working SOL-10 or SOL-20 computer manufactured by
Processor Technology. I am also looking for the Helios II disk drive
unit and any software/manuals/cassettes which you may have. Very
seriously interested.

There's also the m100 mailing list, if you're not already on it. Kinda
quiet, but in the past had lots of good info. It's hosted at Northernway
(Roger Merchberger (which I'm sure I've misspelled) runs it now) and I'll
bet you're going to ask for the address.... Send a message to
<m100-request(a)list.northernway.net> with subscribe in the subject (I think)
and a blank message to sign up.
