Hi! This was supposed to be a short message but has
turned into another multiple page tome! Sorry! Here is status on the development of the S-100 boards: What’s coming soon: I just reordered the S-100 Serial IO PCBs. These are
respin PCBs to resolve any of the issues from the initial release and add some
minor improvements. http://www.s100computers.com/My%20System%20Pages/Serial%20IO%20Board/Serial%20IO%20Board.htm I expect they’ll arrive in mid to late April or
so. There are about 20 PCBs for builders on the waiting list however
there should be enough in case builders would like more boards or join in late. I am expecting the S-100 ZFDC (intelligent Floppy Drive
Controller) PCBs to be in mid April or so. This was a *very* difficult and complicated
board. Kudos to John for sticking to this project! Anyone who’s worked on an FDC knows how frustrating
they can be! A lot of Guru Meditation required! http://www.s100computers.com/My%20System%20Pages/ZFDC%20Board/ZFDC.htm My plan is to reorder the S-100 EPROM boards next.
These will also be respins to resolve the minor issues from the original and
incorporate some improvements. http://www.s100computers.com/My%20System%20Pages/PROM%20Board/PROM%20Board.htm What I have right now: I still have some S-100 4MB SRAM board and also the improved
S-100 parallel ASCII keyboard board PCBs. Both boards are respins and “issue
free” AFAIK. http://www.s100computers.com/My%20System%20Pages/IBM%20Keyboard/IBM%20Keyboard.htm http://www.s100computers.com/My%20System%20Pages/RAM%20Board/4MG%20RAM%20Board.htm What is coming next: John and I have some boards in work. We redesigned the
S-100 IDE board so if you would like one of these please let me know and I’ll
add you to the waiting list. Hopefully I can order these soon depending
on interest. http://www.s100computers.com/My%20System%20Pages/IDE%20Board/My%20IDE%20Card.htm We are currently working on the S-100 8086 CPU board, S-100
68K CPU board, and a completely redesigned S-100 Console IO board. These
are developmental and I have no estimate on when they’ll be ready. http://n8vem-sbc.pbworks.com/w/browse/#view=ViewFolder¶m=S-100%208086%20CPU%20board%20%28prelim%29
(will be the basis for future x86 CPU boards and second prototype board on its
way!) http://www.s100computers.com/My%20System%20Pages/Console%20IO%20Board/Console%20IO%20Board.htm
(second prototype board in build and test!) http://www.vintage-computer.com/vcforum/showthread.php?24550-N8VEM-68K-board-build-log
(Thanks to Rich, John and I are working on an S-100 6502 CPU board and
getting close to a prototype board order http://n8vem-sbc.pbworks.com/w/browse/#view=ViewFolder¶m=S-100%206502%20CPU%20board John has been very busy writing IDE Board and ZFDC BIOS
software and has posted material here: As per usual, these boards will be offered to the S-100
community roughly at cost or $20 per PCB plus $3 shipping in the Of course, if you have ideas for future boards please let me
know. For instance, we could make: S-100 Propeller prototyping board S-100 SCSI board S-100 bus exerciser board S-100 ISA bridge board S-100 ECB bridge board S-100 uPD7220 Graphics Display Controller board S-100 V9938 or V9958 VDP board Thanks and have a nice day! |
