I seem to remember having seen a gorgeous GUI-fied Unix packet
sniffer package from Curtin University in Australia. PacketMan or
something?

An idea for who use classic computers: since we usually require plenty
of terminals to attach to our classic computers, those compact Apple
Macs, such as the 512K or SE, found in more plentiful supply than
terminals at hamfests, have one very good use: use them as terminals
running terminal emulation software. While other microcomptuers such
as IBM type toy PCs are also useful as terminals for computers, the
old Macintoshes consume less electicity.

I second this. There are several VERY high-quality terminal
emulators available for Macs. That same Mac can also sit on the
ethernet for lan access as well (for the later NuBus machines, that
is)...

It's just as well, he wouldn't be able to make much use of his ARC-5
transmitter on the air in un-modified condition.

I do recall an article from '73 magazine in the early 50's, that
told you how to chop up an ARC-5 transmitter to turn it into a
VFO. IIRC, you chop the chassis off at the oscillator coils. . . .

Sometimes plastics are used in very interesting ways. I remember one
Sony Walkman-style tape transport from the 1980's, where there were *zero*
metal screws in it. The entire assembly was snap-together plastic.
Cheap? Absolutely! But design-wise, very interesting.

There are several sources for this info. Look for Ralf Brown. He
made an "interrupt list" which is just a list of *all* interrupts.
Mike Podanofsky wrote RxDOS, a DOS clone for the book "Dissecting
DOS" from Addison-Wellsley. His company is API Software in New Hampshire.
Try http://www.freedos.org/files/distributions/rxdos/

That was the thing I was worried about. Maybe I'll write Command.com
natively
instead.
Someone suggested emulation from disk, and that's exactly how I was thinking
of doing it.
Where can I find a list of INTs DOS uses? I checked a couple of bookstores
but most of them aren't too helpful with low-level DOS.

At my last job I had the luck to have access to a real/live solder sucker
component remover. I found it on the top shelf of the electronics lab and
fired it up. The rig was a small vacuum pump with a long hose attached to
it, allowing the heated air to cool somewhat, with a glass tip. The glass
tip was filled with some kind of mesh filter where the solder that was
removed could cling. These little solder filters were replaceable. This
glass tip was attached to a soldering iron. The vacuum pump was controlled
by a foot switch. It took some trial and error to use the system. It takes
some eye-hand coordination to operate this system. Don't try after 1-2
beers. I also need longer arms because my vision is extending. Works well
for small number of components, not very production oriented.
The whole system is probably still in the lab and hasn't been used since I
left.

Other way around; SOS was first (on DEC-10). I got so accustomed to it
that I copied Alan Miller's 8080 version into an extension of the old
Processor Technology Software #1 (also known as SCS- Self Contained System),
and later implemented it in PL/1 as part of a custom command environment
for the primos operating system at revisions 17 and 18 (Prime later
added its own command-line editing).
I have the 8080 code for what I called 'SCSNEW' (it has a ram-based
file system, cassette I/O, hooks into SOLOS for P-Tech SOL owners),
code to drive an IMSAI UCRI tape board, debugger, and god-knows-what
else I dumped into it and forgot about.
The source was set up for Intel's Mac80 cross-assembler. You'd need
to make a few changes to it for other assemblers.
If anyone's interested in it, let me know... -doug q
Anybody know where I can get a quantity (<10) of
DEC MMJ-to-MMJ cables (for hooking a VT320/420 to a MicroVAX /
VAXstation) and some MMJ-to-DB25F / DB25M adapters?
I tried contacting Tim Shoppa, but his zShops stuff wont let
me order the adapters and he hasnt responded to multiple emails....
Thanks.
Bill
