HP 1631D logic analyzer, some basic questions:

        You can save the current session, but the base unit (without a mass storage
device attached via 488) only saves the current setup. It's on the System
screen, the option at or very near the bottom.

        I'd have to dig up my service manual for my 1630, but I believe they use
EEPROM for backup. There's a disk drive available, the 9122C, if you can
find them (not exceedingly rare, maybe 1 or 2 show up on eBay every 4
months). They tend to go for around $150 last time I checked.

        I've thought it would be nice to have a 9122C emulator for the PC. I have a
488 PCI card (National makes them), and I think with a little software, it
could be a mass storage device. That'd be pretty neat to have a rack of
virtual diskettes to store setup configs based on projects and such.
