Title: Amiga 500/1000 bus expander project
Post by: blanning on January 05, 2011, 01:23:08 AM

I picked up an interesting bit of hardware on ebay.  It's one of these without components:

Does anyone have a way of getting at a component list for this?

It's not going to be as easy as just getting components without the custom programmed ROMS it wont work. There is a simpler version of the expander listed in the A1000 Service Manual.

I talked to someone who used to be involved with bill's board.  He
pointed me to this:

Looks like there's schematics, information about trace errors on the
board, and some experimental equations for the PALs, but apparently
the originals are lost.
