Hi all,
I just acquired an Epson PX-8, minus documentation of course, and I need
some help.
Questions:
- What is the RS-232 DIN plug pinout? Or better yet, a PX8-to-PC wiring
diagram?
(Digi-Key appears to have the plug, part # CP-2080-ND for $1.22 -
800-344-4539)
- Can I connect a floppy drive to the 50-pin connector? If so, what
specs does it expect?
- I assume the SP OUT connector is for a speaker; what are the A/D IN
and BRCD connectors for?
- Anyone have a spare PX-8 keyboard protector shell they want to
sell/trade?
Any other info appreciated,
thanks
Kai
To anyone who's sent me e-mail to be put down on the list for an HHC, if
your mail bounced then please post it publicly here on the discussion
group, and everyone excuse these people in advance. My service provider
seems to think customer service is a joke to be played on its customers.
I'll be switching to a provider which can handle the mundane task of
exchanging e-mail. Note to the wise: stay away from CRL Network Services.
Everyone else, if your mail did not bounce, do not send another request.
I have your request saved, I just did not respond to you. I will be
compiling a list tonight and will post it so you know if your request has
been received. Thanks.
Sam

That's certainly the HX20 pinout, and it's very sensibly arranged. Any DIN plug
that will physically fit into the socket picks up a useful set of signals.
A 3-pin plug picks up ground and both data signals
5-pin adds RTS and CTS
7-pin adds DTR and DSR
and 8-pin adds DCD
The later Epsons like my PX4 used a mini-DIN, alas, where you can't play
tricks like this.

Yes, I finally got the fever for the flavor of a Pringles -- Dooh! I mean,
the fever to spark up my CP/M machine... despite everyone & their brother
telling me to check the PSU first.
Yea, Tar & feather me, and ride me out on a rail... but I saved the thing
>from Mr. Junkman, and it cost me $1.00 at an auction... Figured there
wasn't much to lose.
Here's what I have:
It is *not* a Heath/Zenith machine.... It states simply on the front:
Heathkit Computer. No nuthin' else. On the back, I found the Serial# and
the number:
H-120-1.
I'm assuming this is the model number. It has two floppy drives (one of
which the garage door is broken on) a full keyboard (which works fine, but
is slightly sticky...) and an internal green 11" diag. mono monitor.
Something tickled in my brain about those floppies, so as I lumbered around
in the dark in my newly-begun clean-ish basement (Eeeeek!) I found my old
non-working Atari 810 disk drive... and the mechs looked almost exact!
Would these happen to be the same mechanically, would anyone know?
Also, as there was no paperwork for this, so even the most basic,
rudimentary info on this unit would be helpful... such as: which drive is
the boot drive? Top or bottom?
When I sparked it up, everything seemed to work, the tube came to life, and
greeted me with a finger pointing to the right in the upper-left corner...
and stayed there. Every key sequence I tried resulted in a "Beep" except
<CTRL><RESET> which, of course, reset the machine and re-greeted me with
the finger.
Does anyone out there know what I have, and could you tell me? ;^>
BTW, I (of course) would be in the market for a set of boot disks for this
beastie...
Thanks one and all,
Roger "Merch" Merchberger

No, I'm not Tony Duell...I'm Manney. I have the HP-41 emulator ROM, not
the Assembler/FORTH ROM (the HP-41 emulator came with a different FORTH
and some other stuff.)
I have a lot of documentation -- assuming no copyright infringements,
I'd be glad to do what I can. Tell me your needs.
Since I don't live in the UK (wish I did...about 125 years ago), I can't
'elp you with the magazines...sorry.

Does anyone have any old documentation, software, etc., etc., for the old
Radio Shack TRS-80 MICRO Color Computer.... also known as the MC-10. I
just aquired one with the power-supply, but nothing further. And, I am
trying to locate more information on this little unit as well as software
for it.
Thanks,

More information on the HHCs as requested. I should've included this bit
with the last message.

Sam,
Yes they come with power supplies (internal batteries and AC adaptors).I
have very few manuals however.

I picked up a Convergent Technologies CP001/8 along with a tonne of
extra bits this weekend. It is an absolutely fascinating machine, but I
have no idea how to use it. /:
Unfortunately, in all the extensive documentation I picked up (including
numerous schematics) there is not one operator's or user's guide, although
such are mentioned. The OS reference is, apparently, devoted to the
mechanicals: system calls, and so on. Useful, but not at the fledgeling
stage. (:
If someone knows aught about this machine, I would sure love to hear what
you've got to tell.
I also picked up a TI 99/4A and an Apple ][plus, which I shall require
some guidance with as well, as I cut my teeth on TRS-80 machines, and
didn't really even get into computers until I had moved up to a 386sx..
Thanks.

If anyone has any old genlockers (preferably with some software) that will
work on both/either an A600 and an A1000, please e-mail me!
They (my amigas) are becoming paper weights and I'd like to put them to
use as video titlers atleast.
Thanks,
Les

My apologies for this fubar. Pine's auto-upload grabbed CCML #101 instead

Thank you for your patience & understanding. Our barristers,
