People are moving to Texas and don't wanna have to haul it.
IBM PS/3 model 30, VGA monitor, a whole box of software,
printer of some sort. Any takers?
They want about $50, but will take any reasonable offer.
If it doesn't get sold, it gets dumpstered.

Hello,
I bought an Epson HX-20 at a Hamfest a weekend or two ago. It's a very neat
system. Somebody cut a piece of foam to fit in their suitcase, and then cut
holes in it to fit the computer, modem, power supply, and cassettes. It looks
like something you'd see on the old "Get Smart" TV show. :-)
Unfortunately, it won't power on. The battery charges to 4.5v, but no
farther. Is that what's needed? The printer will not turn on, either. I'm
thinking its the battery, but want to get a second opinion before buying a new
one. Anybody?
Thanks,
Tom
P.S. Any offers? In addition to the above mentioned, I have a several of
manuals, a bunch of printer ribbons and paper, and about 7 cassettes.
This struck a chord with me...

ABSOLUTELY it is your responsibility. We lost the first 3 months tape of
our son's birth, homecoming and grandparents meeting, due to the theft of a
camcorder with the tape still inside. The camcorder was stored at work, in
a locked and alarmed office. It still got stolen. Probably it ended up in
a pawn shop somewhere. I didn't care about the recorder, but the tape was
priceless. You just never know about data, and in the above situation I
think it is your primary responsibility to make SURE you don't have
something you shouldn't.
We were heartbroken at our data loss. Just because it's in a pawn shop, or
consignment, or in the dumpster - doesn't invalidate copyright, or give you
a right to do what you will with it. If you found a personal videotape or
data and make no effort to determine if it is important to the original
owner, then I think you are abrogating your responsibilities as a good
citizen.
Cheers

Last year I acquired a 1985 Dayna MacCharlie w/o docs or software. The
MacCharlie is a DOS box that hooks up to a compact Mac and aside from
that I know virtually nothing about it.
Can anyone advise on:-
Locating software/docs ?
Which Mac models does it work with (128, 512, Plus?) ?
Anything?

OK, my father's car was stolen once, and when we got it back, we
found a tape in it (apparently of a counseling session) that wasn't
there before. Is it our responsibility to erase it?

I save my programs too, at least to check what they are. Once I've
checked, I generally wish never to see the program again (weird games
that have no way to quit them, strange finance programs, etc.)

Yeah, but very few PCI boards are actually running at the full PCI specs.
I've even seen some PCI versions of ISA boards that work at exactly the same

Well, as unimportant as they may seem to you, their hardware specs will
influence your x86 Linux machines, unless a vendor's smart enough to make
ISA/PCI/AGP boards.

You're right, but still, like I said, you may be ISA-less. It's time that
we killed the bus, I agree, but allowing a smooth migration would help alot.
For instance, my AWE 64's been on my machine for under a week. Now, if I
were to get an all-PCI system, I'd loose my *new* soundcard. ISA's
outdated, my SB isn't.

Anyone have an excess video capture card that they might want to sell or
trade for? It doesn't matter if it's VLB, IS or MCA but I would like it
to be a color capture, preferably in real time (so I could capture
frames). It should also be as complete as possible (manuals, software,
etc).
I can get a "Snappy" pretty cheap but figured I'd find a good capture
card if possible before I thought about going into all of this forst.
It's a whim thing, not a definite need. I just figured it's time to
expand the I/O that the machine is capable of, and maybe start capturing
video clips to use in training videos/software.

I collect home micros, and I recently acquired a Mac 128K. However, it's
been quite heavily modified with contemporary third-party add-ons. It's
been taken up to 1M RAM and it's had a SCSI interface installed.
The memory has been taken up to 512K by removing the 64K x 1 bit RAM chips
and replacing them with 256K x 1 bit chips, plus adding a few discrete
components (not hard, considering the 128K and 512K Macs shared the same PC
board). It has then been taken up to 1M by adding a third-party 512K RAM
expansion board, which plugs into one of the RAM sockets (the chip it
displaces being installed onto the expansion board), and is connected to
the address decoding by several flying leads.
The SCSI interface has been installed by removing the ROM chips, plugging a
daughterboard into the empty ROM sockets, and plugging the ROM chips into
the daughterboard. The SCSI socket replaces the cover over the battery in
the back of the Mac.
So, my question is, should I:
1) Leave it as it is;
2) Remove the SCSI interface (easy, just remove the daughter board, take the
ROM chips out of it and put them back into the motherboard's ROM sockets);
3) Remove the SCSI interface *and* the 512K RAM daughter board (not *too*
hard,
desolder the flying leads (taking note of where they go to, just in case I
want to reinstall the board), remove the board from the RAM chip's socket,
remove the RAM chip from the daughterboard and put it back in the
motherboard's now-empty RAM socket);
4) Take it back to original condition (quite difficult, as well as
steps 1)and 2) it involves desoldering 16 256K x 1 bit RAM chips, (plus
a
few discrete components) and soldering in 16 64K x 1 bit RAM chips).
What are people's opinions on this?

Do I have to program a seek to switch heads? I notice there's a head bit
that can be set during the SEEK command...
Can I just specify the head during a WRITE command, or do I have to seek to switch the head?

Well, I called over to Zendex today to inquire about the system I found
and talked to a sales engineer. He's going to try to dig up some sales
brochures and stuff for me.
On an interesting note, he began drilling me on my knowledge of Multi-bus
(of which I have none) and then explained to me that they still have a
market for the old systems and boards and they are in need of someone
technically competent with Multi-bus to hire on a consulting basis.
What they need is someone who knows Multi-bus, CIM-bus and ISBX modules
for testing and assembly. They need someone who knows enough to assemble
the boards from schematics they still have lying around and to test the
boards' functionality. They currently don't have anyone on staff who has
expertise in this older technology, so they would like to find someone
young, old or in between to hire on as a consultant to do this work (he
recalled a radio program on NPR that we both heard recently about older
technology workers having difficulty finding work as they are being
superceded by younger, more "energetic" workers who work for less pay). I
told him I'd put the word out for him as a favor (and also so that he'll
feel obligated to give me stuff).
The Company is Zendex Corporation in Dublin, California. Their phone
number is (925) 828-3000 and you want to ask for Howard Czapla. I'd
appreciate if you could also pass along to me the name of any prospects
you refer.

I am talking about either. In truth, I am interested in AI, whose goal
is to approach the functionings of the brain. So, whatever features
each shares, or differes in is fine. But I suppose that "idealized"
networks are what I mean, that is ones in a purely mathematical space.
For one thing, how are the connections made if not randomly? I
thought it was essentially based on the closest free neuron.
What kind of summation is it if not linear? Do you mean that if the
threshold is 5, 4 is more than to times closer than 2? What does that
mean, if anything?

Head 0/1 are on opposite sides of the platter so they will always be on
the same cylinder. So there are 512 cylinders of two heads, 40 sectors
of 256 bytes per track (one head/side of a cylinder).
There are a lot of ways to organize that physical layout.

I'll vote for this. My logic is:
a) it's an interesting specimen as is, displaying the ingenuity and
constant striving for performance that the computer industry has had since
day 1.
b) you can always remove the extras later.
a) has it's merits, but wouldn't be my main motivation. b) on the other

I found a really neat computer the other day. Its made by a company
called Zendex circa 1980. It's an 8085 multi-bus machine. Inside it has
the processor board, a disk controller, an I/O board, and a parallel
interface daughter-board bolted to the back, but which is connected to the
system bus by way of a ribbon cable. The front panel consists of 8
interrupt and one reset switch.
A very unique system, in that I've never seen one or even heard of the
company before, but nothing special. However, the neat thing about this
computer is that the company that makes it is still around and in fact is
right around the corner from where I work! When I first examined the
computer, it had a label with the company's address: 6680 Sierra Ct in
Dublin, California. I went there a couple days ago and they are in almost
the exact same spot (one address over now). The slogan embossed on their
front window reads "International Manufacturer of Microcomputers Since
1979". I went inside, explained who I was and why I was there, and asked
if there was anyone I could speak to about the system to get information
(and hopefully documentation) on it. I was told to call back as everyone
was in a meeting so I'll be bringing the system by today to bug them.
I finally had a chance to open it up last night. One of the neater things
is that the front panel circuit board has imprinted on it "Made in
Dublin". Now, the reason this is quaint is because, although Dublin is
part of the "Bay Area", its not by any means considered a part of the
"Silicon Valley". So "Made in Dublin" I think is a cute little
acknowledgement of the fact that the company was removed from the main
hi-tech bustle of that era. This particular area where I'm at is not
foreign to significant computer companies as Processor Technology (makers
of the Sol-20) made their headquarters just a mile away in Pleasanton,
California. It's nice discovering that makers of classic computers used
to be right in your backyard. It's even nicer when they're still around
so you can go bug them for information.

I guess this is a little off-topic, but I'm not exactly sure where to ask
about this... Anyone know anything about the Intellicom Mega-Link four port
buffer? Four buttons and six LED's on the front, a row of eight 256k RAM
chips and three rows of sockets for more RAM, and the three DB-25 and a
36-pin centronics connector on the back. Any ideas on how to hook it up?
I'm gessing there was either a special cable for it(centronics to serial
port) or maybe it was designed to attach to a serial port card or
something...

whenever i find a computer that's been modified, i leave it as is. for
example, i have a mac512 with a internal hard disk called a hyperdrive. quite
a clever setup and i also have an apple ][+ with an aftermarket encoder board
which gave autorepeat, macros, type ahead, and all the characters that the //e
could do. i also have a mac IIcx with a 68040 processor board. i keep all
modifications as they themselves are worth as much as the computer itself and
provide personality to the machine.
