Title: I noticed an annoying thing about the C= 286 bridgeboard
Post by: blanning on January 02, 2010, 03:18:18 AM
I have the sandwich board.  I noticed that when you plug it into the left 16-bit isa slot, the sandwich board covers the other 16-bit isa slot.  :-P   So when you move it over into the other one so that there's no isa slot for the sandwich board to overhang, it partially covers another zorro slot.  

I can just barely get the deneb into that zorro slot.  <:-O  No thanks.  I think I'll live with another missing zorro slot since I have some open.

And what's up with designing the motherboard for 16 bit isa slots, then skipping the 16-bit connectors?  What were they thinking?

They weren't. 8-bit architecture was what they were thinking any sane Amiga user could tolerate for a few minutes before coming back home  ;)

@ blanning

It could be worse! There was a 386 upgrade for that BridgeBoard that extended the sandwich board even further - might have even blocked a second slot, but I don't recall.

Almost certainly cost. I'll bet engineering had to fight management to get just the 2 16-bit connectors on there.

for a minute there I thought you were going to say "It runs DOS!"

I was thinking "it can't do DMA!" :P
