Thanks, Huw. It came up with 4 sticks of 4 MB
36bit memory, placed n alternate slots down from
the top. I now think that it won't ever come up
w/o 4 sticks of something -- I had 2 sticks of
16mb memory (the other 2 went into the 300
4/266) and I guess it just won't boot w/o 4
sticks.
Thanks again. Now the kids can have it and do
their Linux thing. I'll chase down some memory,
or they can.

The AS 1000 series also has a tricky memory scheme. It actually requires 5
SIMMs per bank. It uses the first 4 as one would normally expect, and uses
the 5th for ECC.
I managed to find the manual for the AS1000 on DEC/Compaq/HP's ftp server,
so you might be able to find the one for your system too. I believe it was
linked from a Compaq support web page of some sort.

Sounds like you got a good deal ;)
My AS1000 wouldn't power up when I got it, and the problem turned out to
be a bad connection where the status/control panel's ribbon cable plugs
into the backplane.

I got a "defective" AS1000A at a very low price. The "defect" was
putting the memory in the wrong set of slots. Also, early 1000A systems also use five SIMMs per
bank, but later 1000A
systems just use four x36 SIMMs per bank. I did find with my early
1000A system I could use four x36 SIMMs in each bank rather than five
SIMMs in each bank.
Thanks for the tip, I'll certainly have to give that a try.
