Hi John and I have just completed a new S-100 board and are now taking reservations for the first batch of manufactured PCBs. It is the S-100 Parallel IO board which provides four input parallel ports, four output parallel ports, and a PC compatible Centronics port. It has debugging LEDs and other features to help get your S-100 system working in top shape. The board is designed to be reliable and easy to assemble.? The schematic and PCB layout files are on the N8VEM wiki here http://n8vem-sbc.pbworks.com/w/browse/#view=ViewFolder&param=S-100%20Pa… lIO There is an article on S100computers.com here which describes the prototype board. http://www.s100computers.com/My%20System%20Pages/Parallel%20Ports%20IO%20Boa rd/Parallel%20Ports%20IO%20Board.htm The PCBs will be $20 each as per the usual arrangement.? Shipping in the US is $3 for a single PCB and $2 for each additional PCB.? Shipping internationally is $10 for a single PCB and $3 for each additional PCB.? This is for the bare basics USPS first class postage with no tracking or insurance.? The builder assumes all risk of delivery as per usual arrangement. Please send a PayPal to LYNCHAJ at YAHOO.COM with ?S-100 Parallel IO board? to reserve your board.? I will place the PCB manufacturing order as soon as I get to 20 units and will get a few extras for those who come later. Thanks and have a nice day! Andrew Lynch
