I have been looking for a Heathkit 3400 Microprocessor
trainer for *years*
and there was one there -- 6808 uP (6800 w/internal timer, same instruction
set), 512 bytes RAM (a pair of 2114's - amazingly, they still work), 1K
ROM, and (6) 7-segment LED's for primary program output...
I have three (well, two working, one for spares), and they are nice litle
units. One has the 2114 RAM, and another has the 2112. Also different
processors (6800 vs. 6808).
I also got Heathkit digital trainer (3100, methinks ?)
That's a nice unit as well. Basic, but provides a lot of the "standard"
functionality you need when working w/ TTL.
$3.00USD each.
*Whoof* MUCH less than I paid!
Anywho, I (unforch) didn't get any dox with the
trainer
I have a hardcopy of the 3100 manual I could photocopy for you, and I have
the entire 3400 manual (except schematics) scanned in the PaperPort format
(Windows viewer available, don't know about other platforms). I could send
you a CD with the files, or I could print a copy and send it along... No
charge either way...
email me off-list, and we can work out the details (mailing address, etc.)
