I interpreted "disappear into the black hole of a private collection" as
meaning "regrettably unavailable for viewing and/or use by anyone but
the collector". This has nothing to do with how well the systems are
preserved.
And while the particular choice of words may be somewhat inflammatory

As mentioned, I find it best to cut the pins off the IC right at the IC
body and then remove them individually. Once the IC is removed, I use a
third hand to hold the board vertically, and then grab each pin with
tweezers or needle-nose pliers from one side of the board and lightly
touch the s
Thanks for doing this! I do have a few questions regarding emulator
software:
- You mention that the emulator combines "the SimH project structure"
with Wild Hare's commercial code. I take this to mean that the emulator
is an extension of simh to support the listed DG processors and
devices

I have not studied the RP2350 datasheet closely (and I'm definitely not
an EE), but as I understand it, the caveat here is that 5V tolerance
only exists while the device is fully powered (IOVDD at 3V3). At lower
supply voltages (e.g. during startup), digital I/O pins may be damaged
by voltages
