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?

Wanted: Manual and/or switch settings for Intel iSBC-012CX memory card

by eric＠brouhaha.com

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! Eric

Mate-n-lock connectors?

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. -- Pete Peter Turnbull Dept. of Computer Science University of York

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. -- Pete Peter Turnbull Dept. of Computer Science University of York

exabyte tape unit

by ghldbrd＠ccp.com

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 -- Gary Hildebrand ghldbrd(a)ccp.com

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. -Dave McGuire
