    NEC Multisync 3D with Non-VGA Adapters

    Thanks for this, it indeed saved me some hassle (12 years later)! I just picked up a MultiSync 3D with only the HD15 connector. I built a CGA adapter using your pinout and it works great!

    Looking for Kaypro SWP Co-Power-88 Core Software

    Small update: my system wasn't able to boot the disk I created from copwrcpm.td0, but it could read it in drive B when booting another disk in A. I was able to get the ramdisk to initialize at address FE-FF successfully (the default did not work). I was not able to get it to boot msdos.com, I...

    Looking for Kaypro SWP Co-Power-88 Core Software

    Sorry to bring this thread back from the great beyond, but I've got a 4+88 (with the full height drives) that came with MS DOS 1.25 disks.

    Kaypro 4 Tandon DSDD Drive B problematic

    It's a Tandon TM-100-2A. I toned out all the pins on the PCB, checked the solder joints, and power supply voltage. Still no luck. Then I swapped in a known good spare drive for the bad drive and wouldn't you know it, it had the exact same problems! So I put the bad drive B back in, this time as...

    Kaypro 4 Tandon DSDD Drive B problematic

    I checked items 1-3 and they all seem okay. The caps tested out fine and I even swapped the RPM board over to drive A and it continued to boot and work normally. I guess the next step is to look at radial alignment unfortunately I don't have a scope (yet). I did swap another similar drive from a...

    Kaypro 4 Tandon DSDD Drive B problematic

    Hey all, I recently was given a Kaypro 4 Plus 88 machine in good working order. It boots and runs CP/M and DOS just fine from drive A. Drive B, however, is another story. Symptoms: - Can sometimes display a directory listing from original Kaypro disk - 1/10 chance that original copy of Wordstar...

    QuantumLink RELOADED?

    Tried it again just now and getting the same thing. I have my WiFi modem set to 1200 baud, with the correct hostname/port spoofed to 555-1212 and I can see on the oled screen that it's connecting successfully, but then I just get endless plusses.

    WTB: Sony PVM 1342q Mainboard only

    I know this is a long shot, but I'm looking to replace the main PCB in a PVM 1342q that got damaged pretty badly in shipping. Thanks!
