Well done! I have to agree, if you put small figures around the motherboard, it would
almost look like a futuristic city! :)

Nice setup @SophieRose. I have the same AT Speed board on my H5. You might want to get hold of a 80287 co pro on eBay there are plenty around.

Interesting Stack you have there @SophieRose

I presume that the FPU board is the one in the Megabus slot?

I'd like some sort of video adapter for the Mega of mine that has that bus free. Two of mine have an IDE adapter in that slot.

I also have a similar PC card in one, they are 'interesting'

Nice work.

I was thinking of doing a shout round at some point, to see how many people want a MegaBus to ISA adapter.

Then go and ask Frank Lukas very nicely if he would interested in building up a batch.

Was just waiting for Xmas to be over really before I asked, as people may have some cash by then.

@SophieRose Nice system BTW. Truly lives up to the name 'Mega'.

Glad you found a PC Speed eventually. :)

I'd definitely be interested in a Megabus ISA adapter even if it was just a PCB I had to build, also would like to get my hands on a VME to ISA adapter for my MSTE.

Apologies @SophieRose we :threadjacked: your post a little!!
