    I recently purchased a third-party toner+drum unit for my Brother that costs less than the same toner-only cartridge at the local Staples.

    On the other hand, I have a Xerox Docuprint laser that...

    You should be careful in any case. I had a Tandberg SLR drive and flashed the wrong firmware, essentially bricking the unit. Worse, the EEPROM PLCC was soldered in. I eventually rescued the...

    A lot depends on the boards and connectors used. I grabbed an old system off the shelf that hasn't had its cards out in over 30 years. Powered right up--even the hard drive (a Rodime 203--not...

    ...and if it's old card, it may well be subject to wear already. Once you're through the copper base layer, it's usually curtains for the card. So I avoid any abrasives at all.

    Consider the...

    That last one would be my method of choice--either that or some plain old contact cleaner. I don't like erasers, particularly the pink ones used on pencils, because they're abrasive. A gum...

    The Model 20 was supposed to be the replacement for the ubiquitous 1401. The 1401 was very popular in 709x shops as a SPOOL driver. I wonder how many 1440s still exist.

    Sure, but for nearly 70 year old technology, it was remarkable. Somewhere, there's a recording of the thing being used--it's not exactly high-fidelity. There was another system that used a...

    Might be worth a shot to see if the drive is started and a disk inserted results in correct centering.

    Believe it or not, floppy disk centering was a big deal back in the day. When the first 5.25" drives came out with DC controllable spindle motors, there was a huge problem with disk insertion when...

    There's a unit on eBay now for USD$350. I suppose one might call this the first floppy disk. According to the commentary, foldable, too--try that with your favorite 8" floppy.

    I haven't grabbed one of my YE data drives off the shelf yet, but one thing to inspect is the nylon "cone" that's inserted into the hub and secures the floppy. Sometimes they crack or break.

    However, there were many third-party telnet servers for 2K and XP (and NT). Here's an example. I can't make any claims for it, however. Google around--I suspect that you'll find a good one.

    There are schematics of the keyboard unit online, so it shouldn't be very hard to figure out. Mostly rewiring.

    No, the 6300 mouse is a bare quadrature unit (i.e. gutless wonder). Think, say, Atari ST mouse.

    Most of those use "phantom" clock chips, e.g., DS1315, so use up no I/O addresses.

    No--I mean that almost all of my hosts run Linux, not Windows; They're mostly Debian or Ubuntu, although there are a couple that are OpenBSD. FWIW, I don't have any problem telnet-ing to them using...

    Just trying to put the "as old as photography itself" to bed. That would extend to what, the 1820s or earlier (cf Schulze).
