Hi! With our recent successful reorders of the S-100 IDE V2 board and S-100 ZFDC board PCBs I’d like to speed this process up a bit. Last night I reordered the S-100 4MB SRAM board and S-100 backplane PCBs. They should be here in about three weeks or early July 2012. The S-100 4MB SRAM board PCB is identical to previous versions *except* I updated the fill zones to use thermal pads rather than including the ground pins. This is a relatively minor detail but several builders found it difficult to solder the component ground pins with the rather large fill zones acting as a heat sink. http://s100computers.com/My%20System%20Pages/RAM%20Board/4MG%20RAM%20Board.htm http://n8vem-sbc.pbworks.com/w/browse/#view=ViewFolder¶m=S-100%204MB%20SRAM%20board The S-100 backplane are the Rev 1 versions from the previous cycle and completely unchanged. http://s100computers.com/Cards%20For%20Sale.htm scroll down about 25% of the page http://n8vem-sbc.pbworks.com/w/browse/#view=ViewFolder¶m=S-100%20backplane As I recall, Rich Leary did a nice write up on constructing the S-100 backplane. Hopefully these boards work out and we can get further down the list of PCB reorders this summer. Thanks and have a nice day! |
