Ok guys, I guess there are more die-hard S100 users out there than I realized! Was actually expecting no response. Seeing the interest I will go ahead and order the board from PCBCart with actual gold fingers etc. i.e. a production board. For the same reason, I have just added the ability of the ISA bus to trigger S100 bus interrupts. Realize for serial ISA boards that might be useful. I’m going to Europe Sunday, so I will try and get both these orders (PCBCart) out by tomorrow night. Thanks for the offer Todd, I’ll just do it here.
John

Subject: [N8VEM-S100:5357] An S100 Bus to IBM-PC ISA Bus converter board.
This is another S100 board that has a very long history. Andrew and I did some 6 prototypes over the years!
This is a board that can be used to utilize IBM PC/AT ISA bus boards in the S100 bus. I have used it principally to construct and debug various ISA VGA video boards. However it can be used for other boards as well such as serial, parallel I/O boards etc. It will not work with ISA boards that require DMA or Interrupt requests. It's primary use is to checkout MSDOS software with PC hardware.
Please note this is a highly experimental board and definitely not of general interest. I contains some 6 GALS (22V10's) that allow a large amount of inter-bus signal arrangements. Please see here for a brief summary/description of the board:-
Anyway I'm about to send off an order (to Advance Circuits), for one or two boards for my future use, these will be boards without gold plated S100 bus connections -- since the board will only be used occasionally.
I’m surprised with the response for the MSX – VDP video board (I thought only a few would want one) so just in case some S100 bus die-hards would like a copy of this board please let me know ASAP. This is definitely going to be a one-time order. Attached is a picture of the board in KiCAD.
