Well, the pc532 will always have a special place in my heart.. It's
not a question of utility so much as it is the fact that the N32K was
a GREAT CPU, and if it hadn't been for such blundering on the part of
National we might have even had a chance to live in a day and age
where we LIKED the architecture we were using. Instead, the least
deserving (IMO) architecture won and now I'm typing this at you from a
Pentium machine.
I keep my pc532 around as a reminder of what might have been, and as a
possible lesson for the future. I figure for what I've put into it,
it's been time well-spent. At least I can say that I saw a machine
based on the 32532 before it (the chip) finally died! :-)
Anyway, I have a success report:
NS32000 ROM Debugger
Version: Sun Nov 24 21:57:39 1991
Auto-boot enabled.
RAM free above 0x131c
Command (? for help):
My pc532 lives!! Yes! :-)
And with a boot ROM that's almost 4 years old.. Yow! Nonetheless, I
think I have one of the very last generation ones since my command set
is:
Command (? for help): help
Command arguments may be expressions. Type HELP = for expression syntax.
For additional help, type HELP <command>. Commands are:
backup baud boot breakpoint bspace
cpu crc disassemble download dump
edit espace fill fpu fspace
gpr help images initialize mmu
mode move partitions raw read
restore rewind run search set
show step trace tread twrite
write wrmark = ?
Looks like all the tape stuff and support for that little "images"
area we devised for Minix boot kernels is in there.. Yow, now this
takes me back! :-) I don't even think I *have* the forth interpreter
anymore, nor the original sources for the ROM. Pity, that. I was so
close to making the forth system stand-alone and ROMMable - I just
needed to relocate the dictionary and do the setup magic..
What's next? I have a 240Mb drive stuck into this baby and just
waiting to go. Can anyone here remember the sequence in the monitor
to send a format command to drive 0? :-) Also, I assume that the
DP8490 still remains the "disk controller" of choice? That's how I
have mine hooked up, though I have an extra connector on this cable
that I can use to bridge both controllers and the drive.

P.S. Some of you will find this amusing, but this will also mark the
first time I've ever installed NetBSD.. I've never had the time to
install and evaluate the Intel version! :)
