I'm working on a case design for the 18 slot board.

I'd be curious to hear any comments.

Hi Josh,
I got the card ejectors at mouser.com, ref 749-CP-06-WE. I do not have a board cage yet, I plan to build one soon as soon as I get the 18-slot backplane. I have the active 10 slot board but I think 18 slots will give more room for growth.

Philippe,

Looking good!

Where do you get those cool card handles from?

Hi guys,
an update about my system : now the 4MB SRAM is up and running (actually 64K of it as I only use a Z80 currently).

I modified John's monitor to make it work without the console I/O board, quite easy. I had to force the buffered A20 and A21 address lines of the SRAM board to ground though, having a passive backplane there is not pulldown resistors.

I wonder now what the next step should / could be.... I am quite tempted to build the SMB, I think that would be of great help for forthcoming debugging...

Having lots of fun !!
cheers

Philippe
