Hi!? Some people have asked for more information about the S-100 prototyping boards. They are available on VCGM, eBay (#270407288057) or from me directly. http://marketplace.vintage-computer.com/auction_details.php?name=N8VEM-S100- Prototyping-Board-PCB&auction_id=103791 My goal is to just recover the cost of the PCB manufacturing run -- not a commercial "for profit" venture. There has proven to be significantly less interest in S-100 home brew projects than I anticipated which is why I still have these boards available. If anyone would like to buy some please contact me by email. Thanks and have a nice day! Andrew Lynch
