it's also very possible that i made a mistake when i initially
reassembled the thing. it was very fiddly to get everything back
together. i'll let you know if i find anything interesting.

Is it worth trying to come up with some surgery bodge procedure to
upgrade a 256K unit to 512?
It's a very small change and although there is an added part and it's
tiny and not easy to solder wires to, it's probably actually possible to
cut a few traces and add the new part with fine

Feel free to reach out about this off-list. I've done a fair bit of fooling
around with the various CP/M emulation environments and have found RunCPM to
work *really* well as a daily
unfortunately format fails with the same error. i'll try tearing the

here's what i got:

Haha - Glad you like it Joshua if I do happen to make more or improve on
this one I'll let you know. I don't exactly have ADD but what I do seem to
have is the inability to control what my current interests are and recently
it's been playing with CP/M on the M100, PX-8 and building up a CP/M
Communication all looks good actually. Cabling and serial port are
solid. The problem is only when it issues the initial dirent() as part
of the directory listing process, and gets a hardware fault error code
from the drive.
The drive firmware tried to run the disk and read the media, and
OK! I think there might be a problem with my PC cable.
With a standard 25 pin to 9 pin adapter and a gender changer on my M100
cable, I'm getting some output, but there may be some other issues with
the drive or cable.
I will paste my results below.
I should write up some steps to verify things, both for the cable and
for pdd.sh. It's one thing to say "do this to make this" but then when
it doesn't work, then what? Is something broken or did you get a step
wrong or are the directions wrong?
One thing is with the solder blob in place, you

Hmm, now that rings a bell. (Ba-dump-TI).
Maybe that's why it was

Brian, you
Hi Jonathan,
My whole setup is a total kludge / hack that I never expected to use long
term. I was just doing a POC and built the whole thing in about 10 minutes
with stuff I had laying around but here we are almost five years later...
One day I'll get off my butt and make a proper 3d printed
Hello,
I know it is starting to be off-topic, but some details about how you did the
pi (I assume a zero-w) and the case with the level-shifter would be nice. I've
done this with other components, but I've never gotten anything nearly so
small. I have a pi-hat with a level shifter, and it

Well, know how part of the theme of this thread is things not happening the
way we remember them? I had this flagged as a flow control
