I am Looking for Schematics for an IMS SIO-2 Card. I have been working
on getting my N* Horizon Running. I added the PROM Option to my N*
CPB-A2 but am having trouble with the Monitor Prom. I can't get it to
accept Keyboard Input.
I have a BYT-8 which I am now using to TEST with in order to bypass any
Problems with the Built in Serial Logic on the N* Motherboard. I have
the Manuals for the SIO but they don't have the Circuit Diagrams which I
want to look at to see the Connections from the Edge Connector to the
8251. I am hoping someone may know where I might obtain them.
TIA
