There is no useful technical, low level, hardware documentation, none at all, for non-Commodore bridgeboards. User manuals are totally useless.

Commodore bridgeboard emulation was only possible because Commodore boards' address space, IO registers etc are documented in A500/A2000 Technical Reference Manual.

(Not the first time this has been asked.)
