    I've got the 1st edition of the book on my shelf. Recall running it on a S/360 under DOS/360.

    Interesting language; a little quirky.

    My information shows an 8" Teletek boot disk as MFM HD 26x256x77. I suspect that Flashfloppy running on a cheap Gotek could probably do this and be considerably cheaper than a Lotharek. FWIW,...

    That's what I was saying about head supports--they're very delicate and ham-handed cleaning can damage them. I suspect that it's what happened--one head or the other isn't making consistent even...

    Can one assume that you've cleaned and inspected the heads?

    Are the head supports damaged?

    The second link has Teledisk .TD0 files, but they can be converted to ImageDisk files.

    You can write them with a 'tweener running MS-DOS.

    I don't know what a Lotharek is.

    Forms layout was a real art back in the day--I think I still have my steel forms ruler.

    Green- or blue-bar paper had alternating bars of half-inch color and no color, with the top inch no color...

    If it's a stepping rate, 6 msec. is generally safe for 5.25" drives, but for some very old units. Scratch what I said about multiple restores needed; I missed that you were using a 1771 and not a...

    On some controllers, you have to issue 2 restore commands for 80 track drives. Dunno if that's the case for yours.

    For us, it was blue and white--at 10 LPI it was very useful in counting lines.

    Just make sure that your carriage control tape is correctly punched--with a punch in every column to avoid runaways.

    Given that most higher-level contemporary CPUs and MCUs already have FP integrated into the instruction set, that makes sense. And any new implementation will likely just follow IEEE 754. Which...

    I'm more interested in the speed than anything--and it does seem to be fast. (FWIW, I have Chromium and it's not nearly as fast).

    Anyone tried the BRAVE web browser?

    I've been playing with the beta on Linux and it's pretty fast. Seems to be based on Chromium. Curious about other impressions.

    Don't know if it features machine language, but back in the day, I played with JRT pascal on an 8085.

    Is this for a CD-ROM or a CD writer? The reason for asking is that writing CDs takes a bit more current from the power supply.

    Do you have a working "tweener" with an appropriate drive than can run ImageDisk?

    If you check my blog on PAL cloning, you'll see that the way a previous owner disabled the video on my (used to have) PC 6300, was to simply remove a socketed PAL. Easy and it works--but don't lose...

    I suspect that the 1.2M drives have been fitted to replace 8" ones. An 8" bootable image should work when transferred to 5.25" HD.

    I haven't checked my collection to see if I've got the 8"...

    Thinking about it, it's not as bad as a clavichord keyboard. There, the key levers take interesting bends to make sure that the tangents land in the right place on the strings.

    If you use the 99+ percent stuff, it's best to dispense it into a smaller container for application. IPA is hugely hygroscopic and an open container absorbs atmospheric water quite rapidly. I...

    That also applies to XP.

    I prefer keeping my system clock to UTC. Didn't NT 3.51 do the same?

    Mint 19.2 probably uses GRUB2, rather than the old GRUB.

    You can manually edit the /etc/default/grub file also.

    I use Wine quite frequently in GUI mode.

    As far as selecting video, just use xrandr to select.

    The three-key salute (ctrl-alt-del) is trapped within the BIOS and initiates a reboot--doesn't indicate anything about the MSDOS functionality.

    It sounds as if the system is hung in a loop or has...
