Hi It seems that every now and then, people need a parallel keyboard. There is an auction on ebay for two keyboards that were designed for a Franklin Ace. I've bought from this fellow in the past and these are good quality keyboards. They are NOS. They require only +5V and are ASCII true out. I have hacked the PROM for this board and can give you the locations to change the key behavior for specific operation that one might need for another machine. They can take a standard 2716 but have some type of 2508 on them. They have a 8035 or 8048 as the processor. If no one else bids on these by tomorrow some time, I'll bid on them. It would be better to see these go to someone that needs them now then to sit in my spares pile. Check ebay #5149974404 Later Dwight
