Hi Michael,
I just tested MEMTST3 in VCC with 8MB of memory and what do you know, MEMTST3 detected 8MB of ram and successfully tested all of it!  It took a little while though to see the program to the end of its run.  I set the CPU speed to 1.78MHZ so it would run like a real machine.  This little memory test program is truly the best CoCo memory test program around!  Thanks go to Robert Gault!  I thought I would let you know what I found.  Take care my friend.

I have a CoCo 1 it was originally a 4k machine, it has been modified but all memory chips are ceramic type chips with no markings whatsoever(not even on the bottom) alot of soldered wire jumpers and such are in the vicinity of the ram. I am certain the ram is upgraded. There were also mods to the case, including a cutout for a db25 connector (whatever was there is gone) and sloppy repairs to the keyboard cable. I would like to restore this one as It will give me a 1, 1b,2 and 3. I would like to confirm it is functional before I do a restoration. It does turn on and the keyboard works (it was disconnected when it arrived) basically got it for free with a purchase of 2 disk controllers, which both work.
