ok i released a minor update to isforth and have included a partial
port of the Sealevel Digital I/O API. The code has only been tested
with output from the 8008 and 8018 boards as thats all i have here.
The code is very isforth centric but if anyone has a use for the code
and wants to port it i can help you get to grips with my quirks if your
not able to figure them out :)
