    FreHD, Model 4P, MODELIII/ROM and timing isn't right in Model III mode.

    Using the MODELIII/ROM that comes with the FreHD for a 4P image (Updated ROM too), when in system (FAST) it does not properly adapt to the faster interrupts. It runs the clock at half speed (TIME (CLOCK)). Using a MODELIII/ROM from various disks work or just not having FreHD connected...

    Model II/16 cards questions

    I managed to get a fully working enhanced Model II with the hard drive controller (Thats card is all I really wanted, so yay!...) A few questions, because I’m going to scavenge it for the best parts and then hopefully find a good home for the Model II which does work and made it in one piece...

    Rs badges for the model 3 and 4

    Well the memory badges look pretty close, and this image is also using the right one, so its out there. Only took a few seconds to find that image. I am sure the person selling knows where they got it. This came from redbubble.com

    Tandon 848 Thinline strangeness

    I'm going to start working through the circuit, but if anyone has an idea, I've got a really weird one (well, to me). One drive works fine, and speed is correct. Works, boots, formats, etc. The other drive: When a double sided disk is in, which was what I had when I did drive 0, the speed...

    Tandon Thinline 8" drive question

    So, I've got what is more than likely super crudy heads from this Wabash disk I got my hands on. I have an unused 8" cleaning disk, and before cleaning I couldn't get past Track 0 sector 4, then cleaned it a bit (30 seconds) and got to sector 5, cleaned again, sector 10, again now sector 16...

    Strange issue with New Percom Doubler

    Some of you old time Model I users, what the heck is causing me some crazy strange issues with double density disks. I am using calibrated drives, that are aligned right and the lobes and clamping are correct, and have tried freshly formatted disks using a Model III using the same drive on...

    Disassembling a Model 2

    So this is a good status? But there was an error DC when drive closed. No floppy yet to test. And hoping the other box that is on a different truck has the darn keyboard.... I took the lid off and its relatively clean, just the 4 cards. I put it back on before the darn cat decided it was...

    Disassembling a Model 2

    I've been reading some on peoples restoration blogs on this one, and the project that Alphasite is working on got me thinking. Assuming it gets here tomorrow in good condition, what gotchas are there on taking it apart and restoring this that would make me kick myself not knowing ahead of time...
