A nice H8 bundle up on ebay

116249799172 looks like an interesting one though its outside of my price range considering I already have a perfectly good H8. Maybe some interesting video boards.

It's kind of a mish-mash of parts.  The keyboard and S-100 boards obviously belong to another computer.  Here's a rundown on this one:

- H8 with tin pin backplane

- 8080 CPU board

- H8-16 16K SRAM board

- Unknown 64K DRAM board (not Heathkit, Trionyx or D-G)

- HA8-8 Extended Configuration (Org 0) board

- H8-5 Cassette Tape / Serial I/O Board

- H8-4 Four Port Serial I/O board (early model that used an external oscillator instead of the 8250 internal oscillator)

- Four H8 proto boards (the coolest stuff in this pile)

It's missing the H8-17 controller board.  There would have been no real reason for the modified 8080 CPU board, 64K memory board or the HA8-8 unless there had been a H8-17 controller.

Wow, that shows how badly I wasn't paying attention. I saw weird video boards, but completely missed they weren't H8 video boards!!

I've been doing TM990 stuff lately and have become used to edge connectors at the bottom.
