I have just been given the remains of a Mac IIcx, and would like to
determine its condition without spending too much money. Does anyone know
the pinouts of the 15 pin video connector?
Thanks

I recently was given some Intel iSBC-012CX memory cards. These are 512K
ECC DRAM cards that support both Multibus and an auxilliary high speed
memory bus on the P2 connector (iLBX?). There was also a version that
omitted some components and didn't support the aux. bus; I think that
was the iSBC-012C. There were also partially populated models with 128K
and 256K capacity; I think those were designated iSBC-028C[X] and
iSBC-056C[X].
Anyhow, I'm looking for a manual for these boards, or at least information
on jumper settings.
Multibus originally only supported a 1M address space, so two of these would
fill it up. Later A20-A23 address lines were added, but they were put on
the P2 connector.
Thanks!

I don't remember seeing 8-in-a-row in the Commercial Mate-N-Lok range for a
long time, but two-rows-of-4 still exists, as does most of the rest of the
range. If you can't find it on their website, try emailing them -- I did
that about a year ago for something, and got a very helpful response.
Unfortunately, I can't find the email so I can't just give you the
address, but I seem to remember it was easy to find from their search page.

Yes, PS/2 only uses 4 wires:

/ 5 3 \ 2 (Reserved)
| --- 1 | 3 Signal Ground
| --- 2 | 4 Power +5V
\ 6 4 / 5 Clock

Some Sun and SGI cables use five or six. For example, an SGI keyboard
cable for an Indigo uses pins 1-5, and early 4D series use all six. Some
extension cables sold for mice may have more than 4, because some dual
serial/PS2 mice use them.

Hello guys and gals,
I have a quick question: I just procured an exabyte EXB8505ST and was
wondering if any of you knew what tape it uses and what the capacity is in
MB. Got this at a swap meet for the case, but if the drive is useable, I'll
keep it together. Respond off-list to keep the clutter down.
Kind regards

Wow, if you bought it for the case, you probably got it cheap. 8505
drives go for $100-150 nowadays.
I use Sony QG-112m data-grade tapes in my 8505 drives.
