Hi! The N8VEM S-100 prototyping board PCBs are available. I tested one out and it seems to work fine. It fits in the S-100 connector on the N8VEM S-100 backplane just right and the pads line up with the pins as you would expect. I assembled the components and the proper voltages appear in the correct places. They seem really nice and I am very happy with how these turned out. Pads for +5V, +12V, and -12V regulators with filter capacitors are on the PCBs. You can optionally install them or change them around as you see fit. The PCBs are $25 each plus $2 shipping in the US and $5 shipping overseas. Please contact me off list if interested in some. I posted some photos in the N8VEM wiki S100 folder if you would like to see them. http://n8vem-sbc.pbworks.com/browse/#view=ViewFolder&param=S100 I am really looking forward to building some S-100 home brew computer stuff with these boards. This is going to be a lot of fun! Thanks and have a nice day! Andrew Lynch
