Thanks for the response , the Heathkit ET 3400 is a good trainer . The kx-33b
had only data switches and I am guessing , possibly only 16 nibbles of ram .
Not much you could do with it but I thought it looked interesting . I once saw
an add for it in the December 1979 issue of Popular Electronics page 117. I
also ran across an add for the NRI computer I had mentioned earlier PE. 3\77
Pg. 37 from the add it looks to be called a model 832 .If anyone has the
chance to go to any computer shows\auctions lately and has seen these type of
computers I would appreciate hearing from you .
Frank
Greetings,
I am new to the group , I posted a message a couple of days ago , I was not
sure if it got out . Has anyone ever heard of a kx-33b 4-bit microcomputer or
any 4-bit microcomputer trainer type units .
thanks,
Frank.
hello
i saw two apple IIgs card for the apple lc for sale at a local computer store
and was wondering if anyone wanted them? they appeared to new in box.

I got an Apple ][gs today form a guy in Georgia. It's a ROM 03 model
with 1mb of RAM, an RGB monitor and an Apple keyboard. It has no docs,
floppy drives, or mouse.
Does anyone have a spare mouse, floppy drive, and maybe docs that I can
buy? Which drives were available for this unit? I have mostly 5-1/4" disks
right now, so I'd like to get that type first, then maybe a 3-1/2".
I have a copy of ProDOS floating around but I'd like to get a copy of
GS/OS. Can I run this with 1mb of RAM?
Thanks!

Hi,
I found some DEC circuit boards. They're marked "ZG91100876" and they
appear to be memory boards. Can anyone tell me what they are and what
machine they're for?

Haddock says (now that I'm home) the Compass was early 1982, $6000-8000.
Doesn't mention the others.

Things "that go without saying" are usually what screw up the system.
Things like that are best said up front. Better to have someone say "well,
duh" then to have someone get stiffed.

The best thing to do is to list what you're after with a price of *what
you'd be willing to pay for a second machine.* That way, if I say I want an
osborne 1 and I'm willing to pay $50, and I go out and find one at the same
time someone else finds one for me, I wouldn't mind paying the $50 for a
second machine. Of course, you might miss out on that first machine at $75,
but better safe than sorry (until you win the lottery, of course.)

Forgive me, my ignorance, O Wise One, but what is this Haddock?

As Tony pointed out, 50/60 Hz shouldn't be a problem.
HOWEVER, it should be pointed out that the transformer must be capable
of carrying the power. I used a 10VA transformer to power the one or
two devices that had 240V only. To run monitors and things, you'd need
100VA or so. Transformers do exist for just this sort of purpose, upto
about 2kVA, but V. heavy!
(Rule of thumb for switchmode power supplies - Look at ower consumption
and assume 1VA = 0.6W)
Finally, a tranformer designed for 60Hz must be derated to a lower
VOLTAGE when used at 50Hz.
I hope that hasn't got you all too confused.

Assuming one got a wire recorder working, what is the print-through
situation like? I'd have thought not too good...
