Re: Front Panel Stitch/LED I/O

Just found out the main problem (I also tried 255d as input):

I'm still running firmware 3, which just dummy-output's 0x80 on this input.

Front Panel Stitch/LED I/O

I found here (http://www.oldcomputermuseum.com/altair-8800.html) some information about being able to get the switches at runtime and output to LED's. Is this supported by the Altair-micro?

I tried to load it to A using:
Code: Select all
IN 254d
OUT 255d
JMP 000 000


But that didn't work.
