I went out today found a Cybex Data Reduction Computer. Is anyone familar
with them? It has a tan plastic shell with a QWERTY keyboard and a single
line LED display with a printer on the LH top side. I opened it up and
found that it has an AIM-65 computer board in it. Haven't done anything
with it other than that.

Hi Joe
A number of people slapped lables on AIM-65's. I have
a box similar to this with a few extra boards added that
is AIM-65 based as well.
What other than the shell is non-AIM-65 ??

Me, too... mine came with a board loaded with EPROMs mounted _under_ the
AIM-65 motherboard.
Oh... a little tip - I have proven that the 6520 on the display board can
be replaced with an 6821 (I have a number of 6821s since they were used to
drive the printer port and the diagnostic display for the original COMBOARD
model).
I have more than one AIM-65 at home, but only one display board. One of my
projects is to fabricate a replica on perfboard. Mostly via eBay, I've
managed to pick up a few of the 4-char ASCII displays that are on that board.
Barring that, I was thinking about using some modern ASCII displays that I
picked up for a couple $$ each from BG Micro, and re-writing the relevant
ROM code. Obviously, direct replacement is simpler.

I took this one apart this morning. It has two cards under the AIM-65

The other has 24 2114 RAM chips on it along with two 74154s.

That's good to know. Can a 6821 simply be dropped in it's place or does
it require any other changes?

Very interesting box. That doesn't look like a standard AIM-65 keyboard.
Isn't the keyboard integrated into the board normally?

Nope, it connects via a ribbon cable exactly like this one does. Here's a
picture of another AIM-65 that I have and you can see the CPU board is the
same and it has the same ribbon cable socket in the top left corner.
<http://www.classiccmp.org/hp/aim65/aim65.jpg> I haven't had an AIM-65 with
a keyboard for a long time so I don't know for certain if this keyboard is
the same as the normal ones but I think it is. I pulled the keyboard out
and checked it and the only name on it is Superior and a NAND gate symbol.
Perhaps someone can compare this to their keyboard.

That looks like the regular keyboard... what's different, I think, is how
it's mounted.

They don't tend to fry, but they do get dim with age (as do all LEDs)
