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 recently found a PS/2 MOdel 70. Does anyone have an Ethernet card
for it, that has a coaxial cable connector and that could be sold to me
for
not-too-much?

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.

<< The list is, more or less, on topic, and I've taken this oppertuinity to

a question: My Apple ][ has a Language card called a "Pocket Rocket". Now,
what does this do? Does it let me write in such languages as Pascal, C, or,
on my ][+, Integer BASIC? Also, is RAM expansion avaible to increase RAM to
128K (As I've heard that it could go to...)
Thanks, >>
pocket rocket is applied engineering's equivalent to apple's language card.
it's very small, and doesnt require a cable to the motherboard like earlier
models did.

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
hand, would be reason enough. If nothing is being harmed, don't do
anything now that you could do later.
