Wow...that disk is BEEFY. What's the capacity on that beastie
again?

Over the last few weeks I have come up with the following finds:
1-Osborn (gray unit) with all the manuals and software that came with it
new. I got the original papers it was purchased on 12/24/1982.
2-Apple QuickTake 100 digital camera in the box
3-Dr. DOS 6.0 complete.
4-Four reels of BASF tape - New
5-PB DUO 230 with dock
6-Motorola AlphaMate model N1383A
7-Penware 100
8-PB165 working unit no adapter
9-Multitech Micro-Professor MPF-I brand new unopened box
10-Mac Plus complete working unit donated to me.
11-HP 200LX palmtop PC working unit with lots extra's
12-Two early Mac promotional tapes used by dealers
13-HP 9100-5124 adapter
14-Core memory card, a really great find
The other is not close to 10 years old yet so I will list it another
time. Keep on computing

Could be but since its a slim lince case even if it were EISA it would
have to
be shorter in height. Most of the boxen that require the 120 or so pin
card
do it for mechancical reasons and the busses can be ISA, EISA, and the
AT&T
I have has ISA, EISA and even PCI on the right angle card!

Not quite. "Partitioning" is network jargon for disconnecting a port or
segment. If there's no terminator, the transceiver will behave as though
continually detecting collisions, and the repeater will automatically
disconnect ("partition") that transceiver from the rest. The red LED
lights up to tell you it has done so. It won't self-reset because if it
really were connected to a faulty network segment, it might end up going in
and out of operation.
> What is the purpose of the DB-9 connector?
I'm not familiar with this particular repeater, but I imagine it's a serial
port for management and setup. Modern 3Com equipment has a serial port
wired to the same (non)standard as PC 9-pin ports, but that one may not be
wired in the normal way. It may also do auto-baud-rate detection, and it
probably won't emit anything until it receives a couple of carriage
returns. My old SynOptics 2813 hubs have a DA9 as well, and it's some odd
connection for a modem (they also have a DB25 whichj is a normal serial
port).
I'd pull the card and see if anything on it gives you any clues.
> Could this repeater slow a network down?
Unlikely. You can get different cards for those repeaters -- 10baseT,
10base2, 10base5/AUI, and the 10baseT cards have 3 ports each. 3Com
wouldn't have done that if it were going to significantly impact bandwidth.
It's basically just a buffer; it doesn't process the data passing through
like a switch does. Any intelligence in it is just for monitoring and
setup (partitioning, etc).
Another thing you could try is snooping on the network packets (if you have
snoop, tcpdump, or similar) to see if the repeater emits any packets when
it first powers up. It might be trying to BOOTP to get an IP address, and
if you give it one, you can probably telnet to it and look at the setup.
It probably needs a password, though.
> What does partitioning actually entail?
See above. Some more modern 3Com hubs also have the capability to split
the unit into segments (eg, the SuperStack II PS 40 hubs and others can
have 4 segments) but assigning ports to different segments isn't usually
called partitioning.

Someone said that some people have fried unbuffered amigas by trying to fit
CDROM drives to them - the current draw is bigger and cooks the CPU. That
may well be myth though - surely the IDE spec says things about current
limitations as well as protocol? (although I don't doubt that there are one
or two bad drives out there)
Oh, I fell foul to ebay - that A3000's almost tripled in value over the
weekend. Think I'll give it a miss in future (first time I've tried ebay)...
rather wait for something to turn up where I know what the asking price is!
(fair dues on the A3000 though, it did seem like a bargain at the original
price given how loaded up it seemed to be - I got fed up dealing with
inherent web time delays though and got bored bidding on Friday)
I think I'll keep scouring local ads and loot for a 1200 or something...

well as long as something works :-)
Back when I used to use the A500 a lot I used to have to boot a PC XT
emulator and copy files via floppy that way - it was really quite painful!
(Can't remember the name of the emulator now)

now you're talking! The best computer ever... :-) Hopefully it's a 48K, I
don't think much will run on the 16K version, they never were that popular.
Ahh, the days of interfaces falling out of the back of the machine,
constantly tweaking tape head alignment to get anything to load, broken
keyboard membranes etc. etc. ;)
cheers for the help,

Re: Spaceward Ho, Friends and I have been playing that in a big group
annually for > 10 years. My Mac Plus has participated in *every* annual
Ho-a-thon, and is still my preferred Ho machine (though I switch to the
PB3400 when we switch to Marathon!). Info and order at
http://www.delatao.com/ho/index.html
I'll be happy to answer more questions about it off-list. Strongly
recommended. There's a demo at that website.
Also: Armor Alley. I think this is not sold, not available
freeware/shareware, just deceased. That is a *real* shame, it was a *good*
game. Only up to 4 players though.

A quick follow-up:
It also appears that GMT Microelectronics, the group of CSG people
that in 1994 purchased the CSG operation from the failed Commodore have
themselves failed or were purchased. Their Web site is dormant and in
February someone purchased the domain name. Their phone numbers are "busy."
Any info on this?

Thank you for the morality lesson. However, when games are defunct and the software companies no longer exist, I don't see a piracy issue with using those programs freely. Or perhaps I should tear down my Lisa software FTP server? I was not advocating ripping off commercial software, and I rather resent that implication.
If the makers of Spectre VR are still around and still selling/supporting their older stuff, I'll happily send in my payment. I doubt that they are, but it would be easy to find out and act accordingly. If they're NOT around or are no longer supporting their program, then they have nothing to lose by your using it freely. They've already made their money and moved on.
As a semi-parallel, Penguin Classics are re-releases of classic literature sold for about $2 each because the copyrights and/or royalty requirements have expired over time. I view ancient software similarly (and yes, I would pay a token fee like $2 for an old game, if there were anyone left to take the money). Your classic Mac might as well be a boat anchor if you can't run something on it.
