    Good for you--but are you certain that these aren't stock parts?

    My Artisoft AE-2T is 16-bit but runs fine as an NE1000 in an XT. All jumpered.

    Here's an example that maps the keyboard to dvorak layout

    It's for a PC/XT, but the the general principle is the same--you may be able to get by with modifying only the key table.

    Almost certainly a monochrome (MDA) board. with parallel port. Note the 6116 SRAM (2Kx8); so not even a Hercules graphics clone.

    DOS get its keystroke codes from the BIOS tables. You could modify those to generate whatever you wanted--or write a TSR to hook IRQ 9 and modify things from there.

    The TEC (Tokyo Electronics Corp.) FB-201 and 202 are pretty much Japanese clones of the Shugart SA-400, right down to the grooved plastic disc-and-follower positioning mechanism. The 26-3022 can be...

    "just have a hex calculator handy (or be good at hex math in your head)."

    For much stuff, the "h" command will do:

    If the OP is debugging XUB, (s)he certainly understands assembly, no? :)

    One thing that simple DOS DEBUG won't do is get you to reliably displaying memory inside of a DOS critical section. That's...

    On a K6 or earlier, the installer aborts with a message about the CMOV instruction not being supported. I don't know how essential this is to current 32-bit Linux kernels, but probably can be...

    Well, VLIW had some promise for do-it-yourself instructions. Or customer-supplied microcode.

    Maybe we're all doomed to differing architectural "tweaks". X86 probably is the best of all possible...

    No, the DMA (initially 2-channel) was a full 20-bit implementation, like the 8089.

    Let's face it, the peripherals on the PC were 8085-era holdovers. No way someone would design them the way...

    Intel had hitched its wagon to the iAPX432 for advanced deployment in the late 1970s. Definitely not RISC and probably was far more difficult to manufacture than the 8086. Our Intel sales rep at...

    256KB (parity) were usual for these on 286 boards.

    The 16-pin sockets would probably take 41256 or equivalent.
    The 20-pin sockets would likely be 1Mx1 (e.g. Toshiba 511000, or NEC D421000 or the...

    The "combo" memory layout was not uncommon in the later 80286 boards; 256K, 1M and SIPP. If you want to use SIMMs, you can use a SIMM socket inserted into the SIPP sockets--the pinout's the same. ...

    Much the same reason that I don't care much for HP online anymore. I'd love to know where they moved all of the documentation and software for their older PCs.
