Al,

There were modifications to make a CoCo 64K back to the D board (although it 
was a pain on the D). I have an E board that was modified to 64K. Tandy 
always put 64K chips in for the upgrade to 32K, but they still called it 32K 
because that was all you could access from Basic. I've heard that the early 
64K upgrades did use chips that were 'half good', but I don't know how 
reliable that rumor was. At any rate, they soon switched to good 64K chips. 
Programs that require 64K will run on my CoCo I without issue. Programs like 
Telewriter 64 do report back the 64K available.

As far as 'Video Out Adapter', I assume the earlier post refers to composite 
output. This was a third-party add-on that my ol' gray also has. I never put 
on a lowercase board, but I did do the composite out, the 64K upgrade, and a 
wonderful Mark Data keyboard to replace that chiclet monstrosity. Add in a 
Multi-Pak, a disk drive, an X-Pad, an Orchestra 90, an RS232 pack, a modem 
pack, and a speech pack, and my CoCo is/was pretty close to being maxed out 
for a CoCo I. Don't recall ever using the modem, RS232, or speech pack, as 
ol' gray was pretty much retired from active duty about that time. Still 
have it, though, all boxed up and ready for a comeback if necessary!

Ciao,

Richard
