The good news is that it now appears that WRPROT will do the

It's worked fine for me in the past, but then, I wasn't attempting to
use anywhere near the bandwidth nadanet requires (ie. flat out!)
What about the serial port? � Can you just use the DSR (pin 5) for
input and DTR (pin 1) for output?
I wouldn't know if they were configurable at that level - I've always
been a well-behaved programmer and used the firmware interfaces,
despite their reputation for being awful
They are, actually. At least to some extent.
But that requires more CPU cycles than the disk port, since the signal is
not available at bit 7 (it is in bit 6) and sending requires not just
banging a softswitch, but writing to a register.
I really need it in bit 7...
And having to set up a value to store in a register would be
a timing problem.
The Dx-19 connector is going to become a problem, but at least I can still
use a "shortened" DB-25 connector.
If I can find Dx-19 connectors with hoods, the adapter will fit
inside the hood, with an RCA sticking out the back.
About who plans to use NadaNet on the //c: I do...
OK, I'll keep that in mind!
