Ok, I've forgotten that you said you'd never tell me.
So what's the box for? =P

DIP switches, since it's a trainer, it appears they are used to create
"faults" to troubleshoot."
Just to be clear - you +know+ for a fact there are DIP switches inside,
but you only +surmise+ they are for creating fault conditions?
As mentioned, I was thinking either pricey components or possibly some
sort of anti-theft device.. opening the door exposes a feature that allows
the unit to be tethered to a bench.
This is before the days of commodity EEPROM, so it's not like they need to
write-protect firmware, resident software, etc.

Maybe we can salvage this thread..
If you +do+ happen to be interested in owning an SBC / digital computer
trainer, there are still quite a few Heathkit ET-3400 up on eBay at the
moment. Prices have come up a bit - though not much - from a year ago,
when
they were selling for ~$40.00 USD.
Nice little units, and full documentation is freely available.
Now a question..

I've got the 68HC11 version of the ET-3800 just acquired for probably
more
than I should have. Anyone have any software / experience with
There appears to be a big box on Ebay for sale (x a couple of units for
sale separately) for this as well, or maybe it is for the 3400.
I'd be interested in what people have. Mine came with the processor
personality and the memory module only.
