Hi! Although there hasn't been much interest here in my S-100 backplane prototype project on CCTALK progress is continuing. Thankfully I have found several brave volunteers to test these initial units and help share the cost of the manufacturing run with me. I appreciate their help immensely. Of the eight initial units, I've shipped six and one more is committed. I still have one PCB left if there is anyone on CCTALK that would like to join the project. Much of the testing has already been done and some things have been improved but the basic design is proving to be functional and everything basically works. There are some improvements I am keeping track of such as better labeling on the PCB silkscreen but nothing which yet warrants a "respin." Drawings of the N8VEM S-100 backplane prototype are available on the wiki. The N8VEM S-100 backplane prototype PCBs are $32 each plus $2 shipping in the US. Shipping overseas is typically $5. http://n8vem-sbc.pbworks.com/browse/#view=ViewFolder <http://n8vem-sbc.pbworks.com/browse/#view=ViewFolder&param=S100> &param=S100 In addition to the S-100 backplane prototype PCB there are drawings for the N8VEM S-100 prototyping board which I am developing. There have been several revisions and I am not done with it yet. If anyone is interested please contact me off list. I do not have a firm estimate on the price of the N8VEM S-100 prototyping board but I believe it will be in the mid $20 range probably around $25 each plus shipping. Any comments, suggestions, or questions are welcome. Please be constructive and postive! Thanks and have a nice day! Andrew Lynch
