[Coco] "New" Coco 1 with keyboard and composite adapter

[Al Hartman]

That's not an HJL. I think it's a Keytronics MB-500. And, I've peeked under 
the shield as it had come loose in shipping, and the Extended BASIC is a 
ROM, not an EPROM.

I want to put the mod into all three Coco I computers for the faster 
Drivewire. Can someone tell me what that is?

Did you find that computer with the composite adapter already in it, and
the custom keyboard?  (What was it called, HJL?  JHL?  Can't remember).
I'm always on the look out for my original color computer I lost track
of 25 years ago, which had aforementioned keyboard, a home brew
composite adapter, which would make machine pretty unique.  And I've
mentioned this next bit before also:  The computer had a flawed burn of
extended basic, so the MID$ statement (not function) would fail.  So for
example the following test program would hang the machine:

10 A$="HALLO"
20 MID$(A$,2,1)="E"
30 PRINT A$

If the program completes, it is someone else's long lost coco.  If it
hangs on line 20, you're working with an old machine of mine :)
