Never again.
I warned you about modern open-source, didn't I? I'm surprised that nobody suggested the Catweasel
line. Probably one of
the first, if not the first, transition recorder generally available.
Ranges from the Mark I, which is an ISA device to the Mark 4, which is
PCI. Long out of production--I suspect that Jens decided that he had to
move on.
Problem is that I have no ISA machines with a USB port. And nothing at
all with PCI slots.
Software for that was always open-source, yet nobody seems to remember it.
I suspect that greasweazle appeals because it's cheap. There's also
Kyroflux, DeviceSide, FluxEngine...using MCU based designs.
I am not going to try any of them. I just hope I can find some way to
restore RS232 communications on this machine. As it is, I can neither
do real work nor hobbies.
The idea's the same. What I'm a bit surprised about is that there has
been no emulation of a generic floppy controller offered. It can't be
that complex; if I recall correctly the NEC 765 only used 1100 words of
microcode.
I know the microcode for the DEC RX01 (FM only) which was published in
the printset and the RX02 (FM and M2FM) which was never published but
which I disassembled and commented were not hard to understand.
