They've been around forever. Unfortunately, their NOS stock is getting picked through rapidly as the other places in
the valley have closed.
the valley have closed.
Wrong side of the continent, unfortunately! I only see what they have on their site, and what folks occasionally email me about!If you live in the SF Bay Area I highly recommend Anchor as a place to find parts. They have everything! They also ship stuff.

Al, interesting... Anchor has an S-100 backpanel/motherboard still in stock. Any chance you have any info on slot count or manufacturer. MykeI went over to Anchor today, and they had one of the backplane boards, several IO-3 and another CPU
Scans of the backpane and IO boards are on bitsavers now.
I think I have enough now to put a tiny 8080 system together now.
I sent them an email and just got a reply; they have no S-100 backpanels/motherboards. My quest continues....Al, interesting... Anchor has an S-100 backpanel/motherboard still in stock. Any chance you have any info on slot count or manufacturer. Myke
What are you looking for? I bought a version of this one...I sent them an email and just got a reply; they have no S-100 backpanels/motherboards. My quest continues....
But I am looking for one of the V4 backpanels from the s100computers.com site. I sent an email the other day to 'Josh, AKA "Crusty"', but haven't heard back. But even the one from RetroBrew looks good to. I need to email Todd Goodman about that one.

Which size ? 22-Slot ?What are you looking for? I bought a version of this one...
I also have an IMSAI backplane PCB that's just sitting here...
I'm game for reverse engineering the CB-2, but I am guessing that the one that Al has is the only one in existence.Thanks to Al Kossow, for gathering and scanning these SSM 80-pin boards. The thread caught my attention today, as did the boards. I took some time to look at Al's photos and compare the boards, see if they all fit together. The short story from my view, is that the CB-2 board seems to be different enough from the other boards, that I think it's a stand-alone microprocessor board (likely an 8080). The 8080 board and the I/O board, look like a pair to me; and the backplane board likewise looks like a match to those. My guess is, these were prototypes which did not go into production.
I made more detailed notes about what I saw. There's too much to post here. So I sent them to Al Kossow, to consider adding to his archive of board-photos for this SSM 80-pin "product". As helter-skelter as they look, I think an informed person of the 1970's could determine many of the IC's needed for the 8080 and I/O
boards - the bus backplane just needs connectors. My notes suggest a strategy. The CB-2, is a tougher proposition.
Why one would decode these boards today, I'm uncertain. But I spent my time on it, and maybe that effort if read will encourage someone else.
Plan B is to determine what SSM folks were doing at the time and see if surviving notes lead to documentation about products not released. That's out of my hands.

There is currently a CB-2 board listed on eBay [the listing is not mine].I'm game for reverse engineering the CB-2, but I am guessing that the one that Al has is the only one in existence.
The one in Bulgaria? That is the S-100 Z80 CB-2. Unfortunately, SSM made two CB-2 boards. The Z80 one and (possibly) an earlier 8080(?) version. The one I was referring to was the bare 80 pin version that Al picked up at Anchor and has photos on his archive site http://bitsavers.org/pdf/solidStateMusic/80pin . If you found an 80 pin version of the CB-2 on ebay, i need an item number because i couldn't find it.There is currently a CB-2 board listed on eBay [the listing is not mine].
My mistake - I missed the fact you were referring to this unusual non-S100 board with the 80 pin edge connector made by SSM.The one in Bulgaria? That is the S-100 Z80 CB-2.
