Hi, I'm trying to get the TS2068 added to http://www.old-computers.com;
Would you gents be kind enough to check for accuracy? I'll be taking care
of the picture and description/history part shortly. Anyone want to
eyeball a weight for me? Approximate is ok.
Thanks,
Louis

4. TC2068
Johnny Red · Tue, 21 May 2002 23:43
Hi
I have burned something in my TC2068 (note: Its a Timex Computer, not a
Timex Sinclair).
After some tests I have putted the machine to work:
-16K RAM
-Spectrum Emulator
But I have to take a ram chip so it keeps running memory tests (with the
emulator cartridge).
If I put all ram chips and turn on TC2068 without the emulator cartridge,
vertical bars appear.
I have tested all ram chips in the first 16K RAM bank and always did
PRINT PEEK 23732+256* PEEK 23733
witch always gave 32767.
What can it be worng? 74LS245? 74LS157N?
For a scan of TC2068 board, please visit my website.

Hi Johnny Red,
I am copying this to my friend Glen who may know more than
me about what your problem is.
Take care,
Jack
================================================
Glen,
Here is an earlier email JR sent me about his problem, which
may explain the trouble more clearly.
