Unidentified 8K PROM and Jumpstart Board

I’m trying to identify the board (and the company that made it) in the pictures you’ll find at the link below. It is an 8K PROM board with auto-jump using PHANTOM to disable RAM. Any hints would be appreciated.

Note: the board in question is no longer at the link in my previous post. I have since identified the board and scanned a hardcopy manual for it. It is a PROM/Boot board made by Byte.

It is great that you found the manual for that and copied/saved it.

I would guess this sort of board was intended for the Altair computers. Could there be an application for one in a SOL-20 ? though probably not because they auto re-boot to the O/S after a power failure.

With the auto jump feature, it was primarily for S100 machines without a front panel. In my case it was in a Vector 1 computer that used this board for auto jump instead of having Vector’s own PROM/RAM board.
