Looking for Seattle Computer Products 300 S-100 board
Howdy! I picked up a SCP 200B 8086 CPU board, and there is a companion board called the 300 board that contains bootstrap code, a serial port and a few other functions. By any chance does anyone know where I might find one? - Ethan
Ethan -- They are exceedingly rare boards. It took me almost three years of waiting before I was able to find one for my Gazelle. I really haven't been able to find a 1-for-1 substitute. The CompuPro System Support Board comes close, but would require a lot of customization to work.

The schematics are out there so it would be possible to reproduce, but I dig the history aspect of it all! Much thanks for the info! - Ethan

Yes that’s right. The RTC chip may be hard to find but I have the source for at least v1.5 of the ROM and a Sourcer decompilation of the v1.6 ROM. I don’t think SCP used any GALs on that board. On Wed, Jun 13, 2018 at 6:31 PM Ethan O'Toole <telmnstr@757.org> wrote:
