Hi,
I'm the guy who got the PERQ 1 keyboard from Chris for a $100 donation.
Since I got @'ed here, I felt the need to state:

keys, so I don't think the keyboard collectors are after them for BIG
MONEY.

There is a 1000uf 10v cap on the main logic board just above the Bt display

It is leaking... a lot. (4/4 samples so far)

I picked up a pair (1 set) of these very neat old graphics boards.
Alas I have no idea what they are or if there is hope of using them. One is

Yeah Al, that's a great suggestion. I was looking at the AH1815 last night.
The challenge is getting the whole assembly as thin as the original, which
presents a not insignificant challenge-

Hi folks,
I've recently acquired an Apollo DN100 I'd like to restore to former glory.
Sadly, there are no schematics anywhere that I can find.
I have seen this alluded to, but do not have a part number- anyone got a
lead?
Even better would be to find anything describing the PALs in the system.

These systems are rare enough that it's probably worth fixing instead of
treating the board as a simple FRU. There are schematics on bitsavers for
that board, and they are complete.

Anyway, the CADDstation was a turnkey system based around the Sun 3 so it
