I'll give you the expensive part (up until the latest machines with their
USB, most mac hardware has been up to twice as much as the same thing on
the PC). But EVERYTHING about Mac hardware is easy. Things just work.

The postscript card probably would have been much cheaper. I don't recall
if the HPLJII had provisions for adding localtalk or ethertalk, but there
were boxes available back then that could provide it (plugged in to the
parallel port). The two combined probably would have been cheaper than
your PC + monitor. Which, of course, I won't argue was probably a cheaper
solution than buying some of the Apple branded printers.

Well, that is the advantage of using a GOOD OS (strictly speaking in
comparison to Windows of the era, so compared to Win up to and including
win95). Oh, and it behaves just fine with network connections (regardless
of protocol)... far better than one would expect if you use Appletalk
(once again... it just works... chatty, but works).

Interesting. I have used the DOS card on the 610 (both the Apple
"houdini" card, and the Reply marketed card), the 6100, and the
4400/7200. ALL needed the DOS card cable. And although I haven't used the
7 or 12" PC cards apple sold for other PCI PowerMacs, I have seen them,
and they all use the dongle cable too.
That means, the 640's dos card was the ONLY one sold by apple that didn't
need the cable. Very interesting indeed.

there were 2 basic mod 4's IIRC, a unit that required a PAL upgrade for
more ram and a Non-pal unit... I don't remember how to tell the difference
anymore though :(

LOL! I thought that too, but there's only an 'F' in FDDI on my net :-)

Again, there is one desktop, and one portable. I was relatively sure to
keep all the cables in the proper spot. On the other hand, I can't say I
checked well for corrosion/loose connections/etc.

Jeff, if I can't remove all of this Dr. Pepper from this keyboard, I

I *think* it's an RD53. I have never seen one before, but that's what I
believe it to be. It's not an RD54... smaller than that.

That would be my first thought, except that I have nothing that will boot
any PDP except for that disk. :) Of course, if anyone can supply media for
RSX-11, RT-11, RSTS/E or something else, that would be an option.
It is my understanding that RSX (except possibly RSX-11S) uses
FILES-11/ODS1, to which I have recently acquired the specification.

That is my thought. Either a startup command file, or a UAF file.

It is, and I've made a habit of switching the write-protect button every
time I try something strange. Don't want to loose my only copy of the
system software.
