That's great Andrew, I sent money via PP for 3. Things are really hopping now! I just got the ZFDC boards today. I will stick with the 8086 prototype for a day or two more to see if I can solve this wait state/onboard EPROM issue. ZFDCs look beautiful BTW.

Hi! The S-100 Serial IO PCBs have arrived! These are updated respins of the S-100 Serial IO board from last summer with minor corrections and improvements. The S-100 Serial IO board is a dual serial board (Z85C30 UART) and includes provisions for the V-Stamp Voice Synthesizer, a DLR USB245R USB adapter, and parallel port. http://s100computers.com/My%20System%20Pages/Serial%20IO%20Board/Serial%20IO %20Board.htm The board is $20 plus $3 shipping in the US and $6 elsewhere. Please send a PayPal to LYNCHAJ at YAHOO.COM and I will send your boards right away! There are plenty of PCBs so even if you weren't on the waiting list there should be plenty to go around. Thanks and have a nice day! Andrew Lynch
