Well, you might consider this near example:
http://www.dvq.com/oldcomp/micros.htm
Look down the page for the LabVolt 355.
I forget who "dvq" is, I think they were or are on the list.
On the LabVolt SBC, there's a little keylock
on the lower, left of the
board. What's the purpose of the lock? Are there costly (RAM?) chips inside
there, or...?
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.
