    I decided to play around with the TL866A and the VP290 and am having a bit of a quandary. I tried to erase and reprogram a few of my Chinese 22V10D's on both devices. Not one would reprogram nor...

    PAL's are program once and I don't believe the TL866 has the ability to blow a PAL's fuses. A GAL should be a reprogramable version of PAL. So you would need a GAL16V8 if you want to use the TL866....

    My Tl866A has the latest software for it. I've used it for many EPROM's and it's been a useful device.

    My Wellon VP-290 took a bit of work to get it working on my 64 bit Win10 desktop (Wellon...

    You might have been able to pull data off prior to powering it up if sent to a data recover company specializing in very old drives. Time to look for a replacement drive, IMHO.

    Also, sight along each row of pins and look for any that aren't lined up exactly with the others in each row. When you get that figured out, then turn the chip 90 deg's and sight along the new rows...

    I'll give that a try. Can't hurt to try again, but I just purchased a Wellon 290 in the belief that it has no problem programing these GAL's.

    I see the Lattice GAL16V8 listed for the TL866 with the latest software update, but no PALCE16V8. Software updates did add and correct a lot of programming problems. However, I failed to be able to...

    I'll vote for the Cyrix and VIA cpu's.

    As an inverse of worst CPU's I'd put in a vote for most overlooked - the AMD K6-II+ and 3+ CPU's that weren't sold to the general public IIRC. Very nice...

    At least a package shipped to the UK has a 99.9% chance of making it to the other end unlike some other EU countries (name redacted but a lot of pasta is served there) were there's a better than...

    Of late, I've been replacing classic 7805's with EzSBC's switchers and also using their LM323K switcher 3 or 5 amp replacements.

    You might try jointing the S-100 Google Group since they might be able to supply a copy of a ROM for your system that allows it to talk to the serial port.

    I've got several. First I have an old Heath iron with low-med-high settings, it's been a "friend" for decades and I would hate to get rid of it. One day the heater element will die and that will be...

    I've installed CF card & adapter in a few Pentium 1 laptops, but not a Toshiba. There's a couple of things that cause a failure. A double CF adapter is more likely to not work. Also, not all CF cards...

    With the creation of low cost Chinese 3D printers there should be a large quantity of cheap steppers to purchase to replace the failed ones. Good luck!

    I'm fighting a failed S-100 system at the moment just because a single electrolytic capacitor in the power supply had one of it's leads break free from the circuit board. The net result was that the...
