    Early Compaq turbo speed keyboard combination

    The "6 MHz 386"? Ha ha that made me stop and doubt myself for a second. But now I see the speeds listed on the tables below that and it's more obvious now.

    Early Compaq turbo speed keyboard combination

    One small favor: could you just let me know what is on tables 5-3 through 5-6 for the Prolinea 3/25s or 3/25zs, if it has it?

    Early Compaq turbo speed keyboard combination

    Sorry, I didn't mean it that way. I said "Of course it didn't work" because nothing I initially try seems to work.

    Early Compaq turbo speed keyboard combination

    Nice! This is the most information I've ever gotten in response to this question and I've posted it elsewhere. I'm thinking perhaps I should be using Compaq DOS instead of MS.

    Early Compaq turbo speed keyboard combination

    That was the first I tried. Of course it didn't work.

    Weird 386sx Problem - VGA interference + divide by zero errors

    I didn't even think about a temperature sensitivity with this. Sometimes a chance occurrence is worth a week of troubleshooting. And if the hot air is inconclusive you can always bring it back to room temperature and using freeze spray.

    Weird 386sx Problem - VGA interference + divide by zero errors

    Could you disable the onboard VGA and see what a plug-in VGA board does?

    Early Compaq turbo speed keyboard combination

    Does anyone know if early Compaqs, specifically the Prolinea 3/25, had a keyboard combination that could switch between normal clock speed and a reduced speed? I don't know if this Prolinea allowed this, but I would assume Compaq didn't employ many different methods of this just to keep...

    Simple bouncing ball DOS screen saver

    Random question. Does anyone remember a DOS screensaver that bounces a white ball (or more accurately, a white circle) all over the screen, and could be activated manually with CTRL-Z? I've downloaded a number of DOS screensavers, but none were this.

    Trouble converting .woz > .dsk

    No longer an issue, please ignore. I eventually found another .dsk image that works with modification.

    Trouble converting .woz > .dsk

    Anyone know how to convert .woz files to .dsk? I have this .woz file I got from archive.org (attached) that I'd like to convert to a format that will run on linapple, which doesn't support .woz. I'm testing with Applewin which can load .woz files, and that works. I tried the woz2dsk perl...

    Configuration information for this SMC I/O card

    Someone over on Vogons found a schematic file for this card on the Wayback Machine. After installing a very old copy of OrCAD I can verify this card is an SMC reference design for the main chip. Hence why it's missing the BIOS and PALs.

    Configuration information for this SMC I/O card

    Actually the datasheet for the SMC chip says "IDE Interface - On-Chip Decode and Select Logic" so it is doing decode.

    Configuration information for this SMC I/O card

    I was wondering about that. Something is missing there. But the IDE and floppy interfaces may work as-is if the big SMC chip does the I/O decoding.

    Configuration information for this SMC I/O card

    Can anyone figure out what card this is and configuration for it? I can find the datasheet for the chip, but nothing for the card. I can reverse engineer if necessary but, ughh. Are there any databases for controller cards like what theretroweb has for motherboards?
