Emulation of non-Commodore bridgeboards (x86)

Thank you for emulating the bridgeboards made by Commodore (A1060, A2086, A2286, A2386), but I would like to see bridgeboards not made by C=. The link posted below has manuals for some of them, mainly Medusa, Emplant, and PC 286. But for those that do not have manuals, there are always the adverts.

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.)

That's not to say that other boards couldn't be reverse engineered. But it would be a waste of time and effort in my opinion.

Yes and yes.

They have PC-side only address space that is totally invisible to Amiga side and debugging and reverse-engineering would require use of PC and Amiga software at the same time, disassembling both m68k and x86 code and more..

Or worse. The ATonce+ 286 board has 512Mb of RAM on board. This is not accessible to the Amiga until something in the software enables it.
If you start the s/w then reboot you can AddMem() it
