    The converter can be constructed on a piece of perfboard--I did that for the original prototype. It could even be incorporated into the keyboard shell. If you use the TSOP version of the PIC, you...

    No, it was the same situation for several other manufacturers. The SB started off as the Intertube--a terminal. As the terminal market started to decline, manufacturers figured that they could...

    Uniform was a product from Micro Solutions (sometime paired with UniDOS, an emulator). While there was a CP/M version early on, it was pretty specific to a few platforms. The one everyone knows...

    Modifying a garden-variety Selectric to be a printer was actively discouraged by IBM to the point that you couldn't get one serviced. What I heard was that the clutch assembly in a standard I/O...

    How handy are you? There are basic oscilloscope/logic analyzers based on the "Blue Pill" microcontroller boards.
    But yes, a USB "virtual scope" would do for this purpose.

    There were, IIRC), a couple of "parasite" cards made to expand 2-floppy cards to 4-floppy. Pretty simple really; decode the same DOR (port 03f2h) register, but supply added motor enable and drive...

    I think there's a card by Sergey/Andrew.
    All use NSC FDCs.
    WD1002A-FOX (uses WD37C65)

    All have a BIOS and support 4 drives...

    Based on behavior, I suspect that the keyboard is operational, but for some minor issues. But it would take a 'scope to verify.

    You can do it, but you have to modify the drive slides. And you have to cut the case bezel so the drive is accessible.

    What would you call a "home" printer? I used a Hitype I on my S100 system. Star Micronics had early ads for their dot-matrix printer.

    I suspect that many used a TTY or modified Selectric early...

    Personally, I'd just get an IDE+FDC board and use a CF card adapter. There are ISA 16-bit HD adapters with their own BIOS.

    "Safe" as in probing random I/O ports on some gear will hang the system or create other unwanted side effects.
  13. If you want to use the original FDC board, you...

    If you want to use the original FDC board, you need to add a second board capable of operating on a secondary I/O port.
    If you want to replace your FDC board, then there are 4 floppy controllers...

    Velcro should do the trick.

    I have to confess that I ditched the original HD/Floppy card on my 5170 pretty early on and replaced it with a WD RLL card that has dynamic geometry specification, but also understands floppy FM. ...

    First things first--try to see if a bare-bones configuration works. If not, you've got some work to do.

    Also, make sure that the drive cables are oriented properly--but that's something to check...

    Yup--I ran through the list of supported drives on the Adaptec list; the 1700S is not one of them.

    Good luck in finding a controller.

    You probably need to specify the equipment on the DC37 end. This was not a standard termination and cables from different manufacturers are likely to be different. ISTR that some Bernoulli drives...

    I think it may be used as an interliner in garments. See "fused fiber".

    I use a 3.5" cleaning disk on my drives. Works fine.

    I believe that the original intention of that rectangular plate was to provide access for battery replacement. But I could be mistaken.

    But why an XT-IDE card? You've got a 16 bit bus. ...

    That's what I gathered. If it was on a PC, I'd probably use IDA. Hard to beat that one.

    There are several DOS programs to handle the file. The original ARC (by SEA), ARCE (extractor, by Chin and Buerg) and PKXARC (Phil Katz--and a story of a feud). You can probably find these in the...
