I have the layout for a reproduction SCELBI TTY PCB close to complete. This is essentially a TTL to current loop interface originally designed for interfacing the SCELBI to a Teletype. The board is about 4.5″ x 3.5″ with a connector on a .156 spaced edge for plugging into to an edge connector with solder tail pins. This is very similar to a “Vector” prototyping board. Schematics and a drawing are available on Cam’s SCELBI website.

Here is a photo of an original SCELBI TTY interface board.

I’m not sure how many to make. I’m projecting a bare PCB price at $30 to $40, depending upon interest level. Let me know if you have interest in this board.
