Yea! Thank you!

They didn't require minix. They required the "bruce" toolset. (I think,
it has been awhile.)

Sounds good to me. Or ...532/firmware/, or ...532/prom/

Interesting idea. The memory diag would need to stay uncompressed.

One thing I've been wanting to add is a dip-switch, which the firmware
would read for things like console baudrate and whether to boot multiuser
or not.

Yes! Even just a simple one.

Yes! Perhaps with an option to probe for all LUNs.
It is supposedly possible to add another address wire and use
a 64 KB PROM instead of the 32 KB one. (From the mailing list
archives.)
