    That's going to be difficult--the aluminum case and the shell of the USB connector are one and the same. Right now, I can't see any obvious way to get it apart without utterly destroying it.

    Yeah, that's what it was--needed, as the NSC800 doesn't have RIM/SIM instructions.
  3. Another "shoulda known better" cheap USB pendrives

    I've got an ARM-based Linux box that I run off a 16GB USB pen drive. It's run "headless", so no GUI.

    About 6 months ago, I decided to upgrade the system to the next LTS release. I used a pen...

    Well, off the top of my head, the NSC800 has a configuration register at I/O port 0bbh. Accessible only via indirect I/O instruction, if I recall correctly. It's been a long time...

    AH, okay--I wondered if it might be the SIM and RIM instructions (and the interrupt masking control).

    That one stopped me from upgrading an 8085 board to a NSC800 as well. Not so much for...

    What does running code on the 8085 do that the NSC800 can't? The NSC800 has features that a Z80 doesn't, so it's not really a Z80, is it?

    Help me to understand.

    That's about it. That's also why writing to the medium after a delete really screws things up.

    I've done file recovery on messed-up floppies (those that have almost nothing but fragmented files)....

    I'm not following. Ceramic-package DRAMs were always somewhat of a problem, particularly at higher densities, due to the ceramic emitting alpha particles. Plastic has no such problem.

    Yup. Without undelete tracking, you basically do it by hand, collecting clusters starting with the one pointed to. Can get to be pretty nasty.

    My Altair 8800 didn't come with a serial number badge. (It's a Rev0). Were the numbered ones only for the factory-assembled jobs?

    Better to just clean the board well. Solder doesn't stick to oxidized/corroded copper.

    32bit Win7 plays well with dual-boot. I'm running a triple-boot P4 system with Ubuntu 32-bit, Win7 32-bit and Win98SE. No issues--just be sure to install Linux after Win7, so Win7 doesn't...

    Usually you can use slot 1 CPUs up to about 1GHz on 440BX boards. It's a good chipset with very decent ISA support; something that cannot be said of later chipsets. Slockets can extend the range....

    The 16s was also used as an adjunct to certain Japanese PLCs. I've got some documentation (somewhere) that mentions that the floppy format used with a certain PLC is compatible with the 16s.

    Wasn't the Prairietek 120 a bit different from bog-standard XTA/ATA?

    I also recall that some of the CDC 5.25" Wren models had an ATA interface.
