Does anyone have the pinouts, and possibly information on using the ROM
socket, or expansion connectors (or even the printer connector) of the
Radio Shack model 100. 

What I want to do is use the expansion connector to interface it to a 8255
PIA chip (gives 24 I/O lines). I had the technical reference manual, but
can't locate it now. Also any info on addressing, etc. I have located a 
review in BYTE on page 139 of the 9/83 issue, and ROM info on page 288 of
the 5/84 issue.

Thanks for any help you all can provide!
