Thanks for the tip; I'll check it out.
Last night, for those hardware-hackers out there, I started developing a
level shifter using a Maxxim MAX232 chip which draws power from the DSR line
and has a couple of low-power LED indicators. I'm just trying to fit it into a
DB9 shell...

To all of those that asked what the Model 100 DVI is...
Ths Disk-Video Interface is a rectangular box (mostly hollow), the size of
half of a PC which enables the Model 100 to use 5-1/4" floppy disks and to
hook-up to a standard composite monitor or a TV on channel 3 or 4. It could
display 40x24 or 80x24 characters.
Costing around $500, the unit typically (and I'd have to dig-out an old
catalog to check; it's been a while) came with 1 or 2 floppy disk drives and
had a built-in power supply. The companion monitor (an optional-extra) was a
composite green-screen. The included diskette was for a simple disk-based DOS
wedge for BASIC. Connection to the M100 was accomplished through a shielded,
flat, 40-pin ribbon cable with a custom pin arangement that attached to the
40-pin DIP socket on the bottom of the M100. The standard DIP socket on the
M100 was retrofitted with a ZIF socket to ease the stress on the cable.
The insulation-displacement connector on the M100 side pearced the cable in a
non-standard way, preventing meer mortals from making a cable on their own
with parts from Digi-Key--I tried! BTW, replacements are $24 from Tandy Parts.
As an aside, DOS disks are $5.
As far as I know, the DVI came out before the other floppy drives for the
M100, the PDD1 and PDD2.
I hope that this clears things up.

I've decided to go ahead with plans for the First Annual Vintage Computer
Festival!!!
This is a call to all parties interested in participating with the
planning and development of the show. I have directed this e-mail to
specific individuals in my local area (sorry if I missed anyone) as well
as to the entire classiccmp group. I welcome your support and would
appreciate if you who are local could pledge your help in developing and
participating in the show. I also welcome and would appreciate the
support of anyone not local to the San Francisco Bay Area who is
interested in donating your time to the show. Please contact me if you
are interested.
I hope to assemble the core development team within the next week and
to hold a kick-off party on Saturday, August 9th where a team will be
assembled, the project will be discussed and team members will be
assigned tasks.
I am hoping to run the show during a weekend in the middle of October.
Currently, as I have it layed out, there are a couple hundred man hours of
work to be done in order to pull this off. I think with enough people
committed, this can be pulled off in time to host the show by October.
Please e-mail me if interested. Thanks!

About a month or so back I reported to you about one of the California
central valley area's used computer stores doing a 'warehouse sale'
every Saturday... Well they have lost their lease on their warehouse
and are looking to clear it all out by the end of August.
Details:
The Computer Store running the sale is 'Allen's to Go' and are located
at 13461 Highway 88 in Lokeford, their store phone number is (209)
727-0477.
The sale is being held on Saturdays from 8:00am till Noon in a
greenhouse at a former nursery. You can find it about 5 miles east of
Lodi, Calif. on Highway 12; the address is 10400 Highway 12 (heading
>from Lodi it would be to your right).
Marie Templin, the owner who is usually there, said 'the more you buy
the better price your gonna get.' Last week was the annoucement and
business was slow that day so it hasn't been picked over much yet.
What's there:
- Alot of Commodore 64 and PET stuff retired from the Lodi Schools
- Many old IBM and clone cases, power supplies, motherboards, drives
(INCLUDING OLD HARD DRIVES, BRING YOUR LISTS GUYS!)
- A small amount of some Mac related Jasmine Drives (external HDs,
syquest, etc.)
-lots of monitors in various states of repair and dis-repair
-Old laser printers, old copiers, old phonographs, a couple microfiche
readers, a couple projectors
-dot-matrix printers, cables, etc.
The three or so Osbornes are still there as well as all the Apple II+'s
IIe's, IIc's, III's, drives, etc.
You have until the end of August... Don't delay!

If I do buy this System/36, I need to be able to boot it.
A key is needed to boot the computer. The key switch has 3 positions:
Normal, Locked, and Service. The switch has to be in the Service position
to boot. It's currently in the Normal position.
There are 3 wires on the back of the keyswitch. One for each position, I
think. Which ones would I cross to boot?
+------- Wire one. Normal position.
/ \
+---------- Wire two. Locked position.
\ /
+------- Wire three. Service position.
Books, keyboard and manuals.

Header just about says it all. I'm trying to get an 11/24 fired up, and
it seems to be somewhat single minded in what device it expects to boot on
startup.
Right now, its got an RL02 and RX02 on it and does not appear to be
lookoing at either of them.
So... does anyone have a handy reference to the configuration switches
located on the CPU board which will define the boot (and other) options?
Thanks!

I picked up an absolutely perfect Commodore SX-64 (used 5 times) and a
VIC-20 with box and all flyers, etc (used once). I find the included stuff
fascinating (almost as much so as the machines themselves) as they
recapture the flavor of the era.
The SX-64 documentation makes reference to a DX-64. What's that -- 2
drives?
Also, the SX-64 refused to read (known good) disks at first, then read
fine. Suppose a film had built up on the head, which the disks "scrubbed"?
Anyone ever see that happen?
Anyone want either? Make an offer.
I have a line on some Radio Shack Model 100 stuff in the Research Triangle
Park area of North Carolina. The guy wants to sell ("no reasonable offer
refused") the stuff in a lot, but I only need a few parts of it. Below is the
list. If someone wants it (except the ones marked with "*"), let me know.

It's funny that you said this. I just looked at an RS-232 level shifter
circuit on the MIT MiniBoard robotics controller that used a transistor, two
LEDs and a handful of resistors to accomplish that, but it needs 5v to
operate. Really what I need is a parasitic converter that's powered off of the
serial port itself. I've seen this done with a MAX232 or a Dallas 12?? chip.
Hmmmm, time to circuit-hunt.

Hello, all:
I know that this really doesn't fit here, since I only bought this calc
yesterday, but I figure that someone here may know...
I bought a TI-85 graphing calculator, and it has a 3-wire computer interface.
It seems that for $40, you can buy a cable adapter to hook it to a PC's COM
port. Software can be gotten from TI's Web site.
I don't want to pay $40 for a DB-9 connector and a 3-wire headphone jack. I'm
guessing that the interface is a software-handshaking 3-wire RS-232 setup, but
before I hook something up to the calc, I wanted to ask if anyone has this
calc and can shed some light on it.
TIA!

Hi!
I recently picked up one of these beasts at a second-hand store, and
managed to assemble her and get her running. However, I have been unable
to find out anything about them other than they run the 8086 processor. Can
anyone tell me something more? Like what the OS is, when they were made,
and what tehir arcitecture was? Honeywell, unsuprisingly, couldn't help,
and I found nothing on the web.
Thanks heaps,
Adam.

Hold on there, pardner! This isn't nearly as complex as you think. If the
TI is anything like my Casio FX9700G graphic calculator, with the funky
3-wire headphone hookup, you can most likely do it with 1 or 2 chips or
even just some diodes and resistors. What it is, is the interface is an
*almost* standard RS-232 interface. Speed and all is normal, but it prolly
only works on TTL levels. The PDDs (Portable Disk Drives) from Tandy to be
used on their old, non-MS-Dos laptops did the same thing... used RS-232 but
only at +5V and 0V levels.
Use a diode to change the -12V to 0V, and resistors to change the +12V to
+5V .. it helps to have a cable to test first for that one, tho. On the
Tandy PDDs, the resistor value was 22K Ohms IIRC and any cheap .6V drop
diode would do (read: 1N914 -- everybody's buddy)
Otherwise, just design a small, self-powered 1488/1489 box to convert the
levels, and you're off and running. I was planning on doing this for my
Casio, but haven't had the time just yet.
(Maybe I can just use my TPDD cable... hooking up the appropriate wires???
Something to think about.)
Anyway, I hope this helps!

Hi Kai::
I don't remeber if I got back to you about the Lisa. If I did, I guess
just ignore this post. You had mentioned that you do not have access to
the Office system. I have a set of disk images of the Office system as
well as the workshop that I can email you if you would like. Also, I
have information on removing the serialization if you already have a
serialized set you would like to install.

Did anyone see this? Sounds like a nice system.

I'm curious if anyone knows what this machine is. (What OS it runs, etc.)
It's a Pertec machine with a 68020, Floppy, SCSI?, looks like 4MB RAM,
and serial(?) ports on the back.
The power supply has a "ST-100" stamped on it (along with a June 1988 date)
The backplane itself has ST-98 Rev 003 written on it. The main sockets on the
backplane are two 60-pin slots.
It claims to be a "3226", according to the plate on the back. That info also
says it's of type "P7005".
I haven't seen the machine... this is info I've collected from emailling
the owner. (I guess this machine is a year too new for this list. I hope
you'll forgive me.)
thanks

Hello, all:
Just an update on the Altair info that my friend is scanning for me. Below is
the list. He is preparing a ZIP disk for me containing the files in the PDF
forman. I'll have it in a couple of weeks.
He also said that he wants to scan other materials that he has, such as
Altair Basic and Extended Basic manuals, the Assembler manual and others, plus
the MITS "Computer Notes" as well as material from other manufacturers. I told
him that I want it all (like I would really say no?)
Holy, cow, what a list...

I hate it when this happens...
As it turns out, it's not an RRD40 CD-ROM drive I should be after.
According to a manual I just picked up, it's the RRD50.
With that in mind... Allison? Tim? Would either of you happen to have a
line on a DEC RRD50 drive and controller?
And no, Allison, I've not given up on MOPbooting. It would just be a
Nice Thing if I didn't have to depend on that every time I needed to do
a load.
Thanks in advance.
