I just realized something, about the flashing
LEDs..
They're not just flashing, I think the thing is +running+ or at least
counting. It's counting up through the entire 16-bit address space, and
If you're going to do much hardware work, I'd strongly recommend getting
an oscilliscope. (...)
There have been a few comments & questions about scopes and so forth in
this thread, so I thought it worth mentioning what I've got on-hand so you
know what I've got to work with.
There are three scopes here, all older. Two Telequipment 10MHz models, both
rebuilt, and a B&K 30Mhz model that seems to work OK but I've not been
through it. All single-ended stuff, no differential probes.
Additionally, there's a Racal/Dana 8-place freq. counter, two logic probes,
two logic pulsers, a Wavetek signal gen, half a dozen DMMs including a
matched pair of cal'd Fluke 8050As. Beyond that, it's the typical workbench
stuff - power supplies, variacs, sub. boxes, etc.
So that's is about it, for applicable instruments.
