Hi all, I've had these two "3Com 3Stations" (model 3C1100) lying around here
for the past 5 years or so and I'd like to actually get them running.
Does anyone have any technical details about them; in particular what sort of
graphics adapter is built in (it looks like either CGA, EGA or MDA/Herc), what
sizes of 30-pin SIMMs do they take (and how do you set the memory jumpers) and
how the heck do you get them to boot via the network?
Anyone able to offer ANY advice?
TTFN - Pete.

I *think* this makes the list.. dunno the date off the top of my head...
Anyway, sorry if it's O.T.
The Sun monitor is much too large for my already over-crowded computer
room, so I've set it up to boot a dumb terminal (will later be hooked up
to my multiport serial card when I put the Sparc under my desk..)
The problem is the last guy that had the Sparc really screwed up
/etc/silo.conf and SILO requires me to type 1/boot/vmlinux root=/dev/sda1
ever boot (oh, I run linux ;) ) Can someone tell me how to make
/etc/silo.conf boot the machine automatically? Eventually I'm going to
make it a web server... when I buy a router (probably this weekend.)
Thanks,
Kevin

It depends on what you're comparing *with*. 32-sectored hard-sectored
8" floppies have a bit more capacity than IBM 3740 (26-sector) soft-sector
format. But once you start going to double density, longer (and
fewer) sectors, etc., the soft-sector formats start looking better,
but only because the hard-sectored disks weren't evolving anymore at that
point. They could've kept up, if it wasn't for advances in floppy
disk controller technology which made the soft-sectored formats more
attractive.
In terms of early (early and mid-70's) hardware, hard-sectored floppies
required less "smarts" in the disk controller because they don't have to deal
with sector marks in the read signal. (Remember that early 8" soft-sectored
floppy controllers lacked the smarts to write the address marks, and
they reserved that function for special-purpose formatters. We aren't
talking about a LSI chip, we're talking about a square foot or two
of PCB stuffed densely with SSI TTL.) But
then the FDC-on-a-chip came along (from WD, NEC, and others) and these
had built-in circuitry for dealing with soft-sectored details. Others
(like Wozniak) moved the FDC functions to the CPU and avoided both
the FDC-on-a-chip *and* the square feet of PCB's typical of previous
floppy disk controllers.

The monthly SoCal TRW Ham Radio and Electronics Swap Meet is this
Saturday, the 31st, from 7:30 am -> 11:30 am PST.
The Meet is held at the TRW El Segundo facility, in the southern
parking lots thereof:
From the 405 (San Diego) freeway, take the Rosecrans exit and go
west one mile to Aviation. Turn left (south) [under the Metrolink
bridge] and proceed about 3/4 of a mile... the TRW plant will be on
your right and the Swapmeet itself is in the southernmost parking
lots bordering Marine avenue.
I am in Spaces J21 and J23, driving a white Toyota 4X4 pickup
truck with a black bedliner. Marvin will be there, and my spies
tell me also Aaron Finney and *maybe* Mike Ford too...
I plan on a Brag 'n Brunch after the Meet is over (around noon)
and y'all are invited. 'Driving a Hard Bargain' is hungry work!
Hope to see you there... but please don't show up before 9:30 or
so, as it gives me an opportunity to scarf up on all the *good*
stuff. Providing I can keep Marvin distracted, too....
;}
Cheers
John

So what's going on with this? Claimed? Withdrawn?

Good morning my friend.
How are you? You are being true to your word - haven't
heard a word from you in months on the CCL.
Please let me know how you are. Research projects,
acquisitions (oops, is that still a bad word), and such.
I am very interested.
There have been quite a few computers in and out of
my "ware"house. The Guide to Collecting is getting a
second printing (yikes), an I am a happy mainframe
programmer (MVS, Cobol, DB2, and CICS) at a local
insurance company.
Family life is tough, but we're trying and moving
forward (2 teenage boys left in the fam).
You take care and please give me an update.
Yours in good faith.

I'd heard about it round about ST450 time but did not get any
firm data on it.
Interesting idea. So how did you get 'em ??
