[Coco] RS232 Schematics, was DriveWire survey

[CoCoList for Color Computer Enthusiasts]

I ran across this RS232 doc in my archives.
It's the manual for the CocoPro RS232 pak...but....
At the end of the manual are some extra pages that appear to be added by Marty Goodman (he signed a couple of them, it appears he may have designed it). The first is a hand drawn schematic of the CocoPro RS232 pak. Then following that are several scans of the original Tandy RS232 pak AND Tandy Modem Pak schematics!!
 
Here's a link to the doc:

Hey guys, the schematic to the Coco Midipak are available. It was just a 
modified RS232 pak.
Also there's the paks that John (Gimechip) designed. Those shcematics are 
available. I think one of those is a double RS232 as well as a double Midipak.
They might be useful. If you need them and can't find them (they're in 
maltedmedia... buried), let me know and I can throw them in my dropbox and post 
a link here.
