I wouldn't say a SCSI tape controller is useless, always fun for
installing software from tape just for the heck of it. But that's

Interesting. Then we should definitely try reading it and if we can we
should be able to turn the fuse map back into the logic equations. A PLS173
is a fairly straightforward device.
It is most certainly PLS

A PLS173 does not have a security fuse.
A PLUS173 does

Regardless of what the spec sheet does or does not
The spec sheet from the PAL mfg. (signetics PLS173) seems to indicate
security fuses aren't an option on the model on my board. I have not
actually tried yet.
Failing that, if I can find one locally, there are only 12 bits of
combinatorial inputs.
I could easily whip up a little Arduino project

Curious how you
Is a 720TM any use? I just acquired one... And a BP-1200.…

Does anyone out there have one of these controllers?
There is an unprotected PAL- the address decoder- and I really need a dump of
it. Many programmers, particularly the BP technologies ones, can read it
