I have a couple of old Stride Micro systems, a 440 and a 460, that get

That would be very interesting. I always thought Apricot made some beasts and
remeber the cover of Byte for the first 486 system being an Apricot VX. I would
love to see that machine in person.

BBC BASIC is the best BASIC there ever was, and I feel sad for those who have
never used it to see how powerful BASIC can be with proper structured
programming. It’s honestly like a different language.

Ah, PPC VME cards, add VXworks, funky coprocessors, COTS IO and you have
definitely got something best avoided : details would involve libations.
The conduction cooled chassis are OK and worth repurposing. Contrariwise the
VME bus is best avoided, whether classic 32b VME or the 64 bit revision.

I have recently acquired a Qume Model 842 double sided 8" disk drive.
I have reset all of the settings to factory default and hooked it up to

The drive works perfectly for double sided disks (using the appropriate
index hole).
However, the greaseweasel reports no index puls
Connect an oscilloscope to the output of the single-sided sensor and see if
it works. If so, trace the signal through the logic and see if it gets to
the I/O connector that goes to the greaseweazel.

That might help. It's also possible that the LED/phototransistor for
the SS index position is faulty. The two LEDs (SS and DS) are connected
in series, so you know that at least one isn't ope

Often that is because you signed up using an old email that is forwarded to
