RE: [N8VEM-S100:7341] 80386 Jumper Check...

Hi Gary, I’m back!

I attaching a (large) detailed picture of the 80386 board which shows the jumpers etc. I used.  With the Cyrix chip I could squeeze 40MHz out of this board.  It has no problem running with the V3 IDE board.  The wait states can in fact be squeezed lower I seem to remember with our later RAM boards  but it’s been a while.

 

I am actually working on a better, V2, CPLD driven board as we speak.  That one will be simple and have much better configuration capability. 

In your case how far do you get with the IDE  board.  Can you use the 80386 monitor IDE board diagnostic commands?

I have the Z80 and 8088 boards working nicely with the IDE V3 board, but still can't get the 80386 board to work.

Could anyone who has the 80386 board confirm that I have the jumpers set correctly?
