OK while the rest of you are freezing and getting ready for Christams, we
here in Florida and enjoying beautifull wheather and still fighting over
the election! A few of us are taking advantage of the weather and are out
scrounging for old computers and other interesting stuff. That's what I did
yesterday. My haul included a Morrow Micro Decision, a Tektronix 8002a
Developement system and the external 8" disk drives, an immersion cooler,
six or seven Busch & Lomb model 21 Spectrophotometers and a manual for my
IBM MD-2 Maintenance Device. I ran out of car before I ran out of goodies
so I left behind a Tektronix 4016 terminal, a tektronix 4024 terminal, an
ADM-3A terminal and an ADDS 25 terminal.
One of my coolest finds was a Paratronics model 100a Logic Analyzer with
the manual. This must be one of the first logic analyzers on the market.
It's about the size of a cigar box and uses a scope of other monitor with
an X-Y input for the display. The manual is dated 1977 and it says that
this an improved version of the one that was in the cover story of the Feb
1977 issue of Popular Electronics. (Does anyone have that issue?) The
mauual gives example of how to use it with the Altair, Intel 8080, Motorola
6800, Fairchld F-8, National SC/MP, Z-80, Bit Slice CPUs and the RCA
Cosmac. This will make a nice companion piece for my Altair.
Also spotted a Color Monitor for the TI-99/4. It's nothing but a color
TV with the tuner removed. I knew RS sold this kind of thing but I didn't
know that TI did also. I didn't pick it up but if anyone wants it, contact
me and I'll tell you where it's at. It's in a surplus store and I have no
idea what they want for it.
I'm looking for info on the Morrow Micro Decision. If anyone knows much
about them, let me know.

Does anyone remember or has anyone even heard of the Pan Network from the
mid-80s? Apparently it was a dial-up network system used by musicians to
trade midi files and what-not.
If anyone has any remembrances of this that they can share or, even
better, magazine article cites, then I would greatly appreciate if you
could share them.
Thanks!

IIRC, the T1200 wants 9VDC (there's a block of 4 NiCd cells inside that
suggests to me that it's 6VDC internal and 9VDC to charge it)
I just happened to see one about a week ago at our weekly Geek Lunch. I'm
pretty sure the wart was 6VCD.
Good luck,

A tad over two years ago, there was some dialogue about the Kansas City
standard for cassette recording of microcomputer files, and a chap named
Heinz W. Wiggeshoff provided some information via
alt.folklore.computers, and offered both images of programatic nature and
circuit information on request. (See following.)
If anyone obtained those images and circuit information, please respond
to philpem(a)btinternet.com with Cc to me.
Many thanks.

KANSAS CITY STANDARD
In order to use these inexpensive recorders in the hobby market,
a standard was proposed and adopted by hobbyists. Using frequency
shift keying techniques, and frequency double frequency [sic] modem
techniques, this standard is easy to use. The drawback is the data
rate of 30 characters per second.
The system takes standard serial RS-232C data ... and converts
each bit to either 8 cycles of 2400 hertz (a "1") or 4 cycles of
1200 hertz (a "0"). To generate this, only a few flip-flips [sic]
are required along with a quad NAND gate. Shown in Fig. 4-55 is the
modulator.
[Image sent on request]
[Circuit function, ditto]
The demodulator must detect whether 1200 hertz or 2400 hertz
tones are present. There are many ways of doing this; however a
common one is to detect zero crossings of the input signal. This
will generate either 2400 or 4800 pulses per second.
[Circuit details sent on request]
The circuit for the demodulator appears in Fig. 4-56. The de-
modulator timing appears in Fig. 4-57. Note how one gets back what
one started with, along with the necessary clock information.
If the tape speed varies, the data may still be recovered as the
clock information will insure the UART receives the proper timing
signal.
No special software is needed as this interface makes the cassette
look like a paper-tape, punch-reader combination to the computer.
[Images sent on request]
(This format is found between the KIM cassette interface, and the
One Chip Digital Cassette controller using the NEC UPD371D.)
(Surprisingly, the documentation for my Heathkit ETA-3400 only
mentions the frequencies, not the details of the encoding.)

I know :)

I wasn't talking about the explanation Giordi LaForge would give
for how it worked, but how the writers were likely inspired to
create the plot device.
