Hi,
I'm looking for some (technical!) information on the HP E2447AA or
E2447AB probe pod (for using a HP logic analyser to monitor a 68000 CPU).
I need to probe a DIP64 packaged 68HC000, but the E2447AA/AB are for PGA
parts. So I figured I'd make a "top hat" PCB to adapt the 68k to a bunch

I was the mass storage region specialist for HP Australia when these came out.
They were pretty reliable and compared to the previous 7970 and 7974 drives
that had start/stop capstans, they were pretty good on tapes.
I just restored a 7980XC (HP commercial version of the 88780) and it all worke

That's been my experience, too. The 88780 I use is a Sun drive
Will is right. You have to convince them that it will be worth their time to
sort that particular item out, find packaging to send it and deal with the
typical book keeping required by their particular state, as compared to the
time/return of just tossing it into the fire to burn off the undesir

Sorry, but no. It’s grossly offensive for things that work perfectly well and
that someone might actually find useful to go to scrap. There’s tons of useless
and broken junk that our civilization can mine for scrap, we don’t need to
actually destroy things that have actual value.

computer was suppose to have a battery bank to keep the DRAM from losing data
when turned off, like the original core used on earlier machines. The resistor
detected the battery pack that one rarely use.
