Congrats @donohoe00 your PR was just merged. I just booted from a hard drive on the main branch. Exciting stuff!

Yeah, that's never worked. The Floppy Controller implementation had major issues several years ago. I got it to reliably boot and read/write disk images, but never got to fixing the format process. There's also a few weird bugs where just reading double sided disks occasionally will cause a...

I can do that.

Is there anything we can do to help push the PR along?

Thanks for that. It was my boot partition was too large. I brought it down to 10MB and it boots successfully. I'm able to boot my actual vintage Victor into a 256MB drive, but there must be something different in the ROMs. I was able to format a 256MB drive, and have the boot partition be only...

@donohoe00 I tried out your hard drive branch. I was able to create a blank drive with /chdman createhd --output victor_60.chd --hunksize 4096 --chs 695,5,17 And then from inside the emulator I was able to use factoryf and hdsetup to format and configure the hard drive. I could then copy files...

I made an attempt at cleaning up the floppy code and didn't fully understand what was going on. I figured I'd come back some day and try to tackle it. Once I was able to get the emulator to reliably boot I lost some of my motivation. Thanks for plugging away at the improvements! I was just...

That's excellent! Thanks for pulling those together.

I modified a TEAC FD-55GFR, a different drive, using these instructions https://cowlark.com/fluxengine/doc/Index_sensor_mod_FDD_1.1.pdf for the photocell method. Worked like a charm to read flippy disks. I know these directions don't help with the drive you're using, but I thought it might...

The floppy drives have lubricant that turns to glue over time. Likely that the mechanisms are just stuck by the grease hardening. There's also a gear that tends to break down with age that can cause the mechanism to be jammed. If you search on YouTube you can find videos of folks cleaning the...

One other thing to remember is at the time the 5150 was only one MS-DOS machine. The Victor 9000 came out in 1982 and supposed 896KB in its initial version. It also had memory mapped devices and BIOS above the boundary available for DOS but had an additional 256KB to play around with in the...

Thanks for the readout @pbirkel@gmail.com! I appreciate you giving me the lowdown.

Super nice! I look forward to playing around with it.

@pbirkel@gmail.com I'd love to hear if there's anything interesting in the disks. I'm particularly looking for an early unix that existed for the Victor 9000.

I'd be interested in the disks. I sent you a DM.
