    It wasn't a DOS window, but a win32 console window that can run win32 console applications and emulate DOS applications (assuming it is an x86 OS and not x64).

    Real mode = DOS 16 bit application (one that doesn't run in protected mode)

    They pulled DOS compiling from the free 5.5 release they made which could target win32.

    Ws the 5.02 just an update CD to 5.00? I remember getting the 5.00 kit way back in the day, but it has been a long time to remember... Not sure if 5.02 was just a CD or if they had a 5.02 release...

    My Kaypro has two card edge connectors on its ribbon cable, but I want to try to connect it to a GoTek which is pins. Are there adapters that adapt card edge to a female IDC? Should I just crimp a...

    I've got some modern CMOS Z80's around here that are 10 or 20 MHz, but for some reason I just want to stick with the original. I think there was another point of failure that needed to be capable,...

    I agree and it seems to be the +12V rail. it is normally 11.5V and drops to 11.3V momentarily. I wonder if I should go back to the power supply and try to tweak it up to a more solid 12V, maybe...

    It has the squeezing issue too, when the drive motors kick on. I'll try to get some video of this the next time it happens, maybe that will identify what is going on!

    I'm sorry Doug, I don't mean wavering in frequency, I mean amplitude. It seems to be synchronized to the revolution of the disk so maybe one cycle would be it going from 350mV to 450mV and back to...

    I've tried the radial track adjustment on the bad drive. The bouncy signal at track 0 can be...

    I rocked the long connector going to the video board back and forth a few times and removed/reattached it. So far no problem so maybe it was a bad connection... We'll see!
