Randy, I'm not sure, but I wonder if an old Central Point Copy2PC Option Board
could make a copy of that boot disk. Anyone back in the try it?

I will check that, Brian. Thanks for your help.
My other question is around the boot disk. I was sent 2 boot disks with the
cable, but now only 1 seems to work. I’m worried now only having one working
disk.
How do I back it up? Is there a way to do that with the DVI? Can I create one
in a different disk drive, like the drive in the TRS-80 Model 4P?
thanks
Randy

This sounds consistent with Fugu's idea about old capacitors. It sounds like
both dvi's are marginal, but one is slightly better than the other, and one of
your M100's is slightly better than the other, and so with the two best ones
combined, it just barely works, sometimes.
I would check that voltage as he described and I expanded.

SUCCESS!
Per John’s suggestion (and was thinking the same thing when he suggested it) I
now have a working system. I started trying different combinations of
DVI/M100/cable (of which I have 2 each).
DVI #2, M100 #2, Cable #2, no luck
So I swapped out M100 #2 (32K) for M100 #1 (24K/REX), and it worked!
It’s still a little finicky and doesn’t always work, but has worked multiple
times now. I don’t know if there’s anything I can do to “tune” it so it’s more
consistent, but I”m pumped that I finally got it to work.
I had tried this M100/cable combination with DVI #1, so I’m wondering if
there’s an issue with that DVI. There also must be an issue of some sort with
M100 #1 as the current DVI/cable setup didn’t work with that machine, but does
with the other.
This sure seems like a finicky setup. I would love to see a modern DVI
replacement, perhaps with SD card for disk and video output, that would take up
far less desk space and be more robust.
Thanks all! Any other suggestions for troubleshooting why the M100 (#2)
doesn’t work with this and also why DVI #1 doesn’t work with either M100 would
be much appreciated.
