As long as you have a 6100, you should have a look at this page:
<http://www.kan.org/6100/>.
It has a wealth of information all aimed at the 6100 specifically.

I'm beginning to wonder if it's time I upgraded my home network. The
NICs on most of the machines are 100BaseT, with the odd old machine
sporting a 10BaseT. But it's the hubs I wonder about--two old
National Semi 6-port Datamover 10BaseT units coupled together with a
10Base2 (coax) link. It's that coax that I dread replacing--it goes
between floors and snaking it through the walls was a real chore.
My DSL speed is 1.6Mbps, so I'm thinking that there's little reason
to upgrade the setup. Am I thinking correctly or am I likely to see
an improvement in internet access speed if I upgrade?

ARCHIVE YOUR APPLE FLOPPIES AT THE W6TRW SWAP MEET, JANUARY 2007
Even if your Apple IIe is long gone, you'll soon have a chance to get at
your old data again, when Device Side Data (www.deviceside.com) holds
the second public demonstration of a new USB floppy interface.
USB floppy drives are widely available, but those currently on the market
only support 3.5" disks. The new interface, due to be released later this
year, connects to 5.25" drives. It will also allow the owners of modern
computers to read a variety of old disk formats that ordinary floppy
controllers no longer support.
The demo will take place on Saturday, January 27th, 2007, at the
famous W6TRW swap meet in Redondo Beach, California. Attendees are invited
to bring along a few disks and have image copies made.
The final product will read many disk formats, but the prototype only reads
Apple II disks, so please leave your IBM or CP/M floppies at home for now.
The W6TRW swap meet runs from 7 AM to 11:30 AM in the Northrop Grumman
parking lot near the intersection of Aviation and Marine in Redondo Beach.
There is no fee to attend. Once there, look for the spinning disk in row C.
Besides Device Side Data, many other vendors will also be present, with a
wide range of equipment for sale.
This is an outdoor event and will proceed regardless of weather. Please
carry your disks in waterproof bags in case of rain.
Does anyone out there have a Hewlett Packard 7200A plotter (made around 1972) or a DEC VT50 (not VT52) terminal? I am looking for both of these items for my classic computer center.
Thanks,
Ashley Carder

This reminds me of an interesting phenomenon we discovered in 1974...
the high school had an ASR-33 connected via a leased data line
(telephone with acoustic coupler) to a PDP-8/E running TSS/8 at Clemson
University, 60 miles away.
I can't remember exactly what the code was any more, but it was a very
simple patch -we would deposit a mere three words at location 307
(octal) and execute it (ST 307), and the terminal would log on another
job. So you'd have two accounts open simultaneously on the same TTY!
And if you logged off one account the other would still be open so you
couldn't log off both... they'd have to reboot the system to kill it.
Any TSS/8 gurus know how we might have done this?
We also "inadvertently" deleted the contents of one of the library
DECtapes once... there was a "ZAP" command that zeroed out the tape, so
naturally we would type in "R ZAP" frequently, and get the expected
"WRITE LOCKED" error. One day, though, it actually did it =:^0 Guess
the operator forgot to flip the write lock switch!

> Maybe the 680 and it's basic isn't fast enough for my program?
This is quite possible as interpreting decimal numbers takes a fair bit of
processing. You may like to try this ..
1 A=61456:B=61441:C=61457:D=1:E=0
2 IF (D AND PEEK(A)) = E THEN POKE B, PEEK(C)
3 GOTO 2
.. which should speed things up a bit.
Lee.
I just modified my program to get rid of the polling. It did not really
speed up the display of characters. ; )
I can now see the full records with some duplicated digits here and there.
Its interesting that the program below free running can only process
characters at 300bps
1 POKE 61441, PEEK(61457)
2 GOTO 1
At a 500Khz clock thats over 1000 clock cycles per loop. SO THIS IS HOW
Micro-Soft got started with slow software??? ; )
So any suggestions on getting started QUICKLY with 6800 assembler? Maybe
one that outputs in Motorola punch tape format???
I want to archive Altair 680 KCACR basic before anything else happens to
this tape. I had about 5-6 failed loads this weekend and I don't want to
risk loosing this KCACR basic! : (

Remeber- two types of radiation: particle (Alpha, Beta, neutrons,
protons) and electromagnetic (gamma, X-ray, radio, light, etc). The
particles can make things radioactive, the electromagnetic radiation
cannot.

Well, smoke signals may have lower latency, but bongos would have
higher possible switching speeds and so better bandwidth. Things don't
change much, do they?

What, fixing Windows telnet to actually conform to the spec? Yes,
that's quite a project. :-)

Gimme a break; this "project" merely involves getting the free HypertermPE

Keep in mind that this time around it won't be so hard- just attach two
nylon strings to the
coax, pull it out, attach your fiber or UTP to one of the strings and
pull it up. Leave the
other string in the wall if you ever need a second line.

I still have this slick Nakamichi 7 disk scsi CD changer with audio outputs
on the back. Something like MBR-7?? I wish I had a killer application for
it. I wonder if it has enough front panel control to use it as an audio CD
player without connecting to the scsi bus at all-- something like I'm doing
with my NEC Multispin 6x caddy type CD drive. I have it connected to my
stereo, via coax digital audio out. I only have 4 or 5 caddies laying
around though.

All:
I was doing some closet-cleaning in the shop this weekend and
came across a few things I have no use for any longer or were bought for
projects that never got off the ground (and probably won't). If anyone's
interested in anything, please email me off list. Shipping to the US only is
not included. Trades considered.
* Seagate 9gb full-height SCSI hard drive (new but unused/untested);
ST940800N: $10
* Compaq-badged external DLT drive 5/10gb (SCSI-I; working last time
used): $25
* Panasonic 616 phone system with 4 keysets (untested but bought
working). I have manuals in electronic form: $50
* STD-BUS 14-slot card cage with assortment of cards (2 analog, 2
digital, 2 relay, Z80 CPU and DSKY. May have other cards in it).
I think I have docs for most of the cards and a disassembly of the ROM. NASA
surplus. All cards should work but it was some sort
of data acquisition or process control system so I never finished fully
decoding the ROM to see what it did. $75
* SpareTimeGizmos SB6120 PDP-8 fully built and working in a Lucite
case. All that's needed is 5v adapter. Includes CF adapter
and 16mb CF card with four disk images. $250 (reflects actual costs of
partial kit and parts I bought).
* TI-74 BASIC-Calc system. Includes unit, PC324 printer and AC
adapter. I will also include CD of random information and programs
that I had collected. $40.
I'm looking specifically for a Tandy CM-1 color monitor for my Tandy 2000
and a small self-contained PC/104 SBC (stand-alone -- not for use with a
backplane) with at least a 486 CPU. I'm also looking for an older Mac Mini
(1.42ghz version with Airport/Bluetooth).
Thanks.

Oh my, what am I going to do with these MDI SCSI CD boxes? I have 3 or 4 of
them, each one containing seven CD-ROM drives, a power supply, and some
kind of logical unit controller, so all 7 drives appear a LUNs under one
SCSI address.
The drives are Toshiba XM-5301B, a 4x tray-type (doesn't need caddies) that
works sideways or in the more usual orientation.
Specs here, from http://www.netcomdirect.com/tosxm4xfonco.html
CD-ROM Mode 1 -data discs
CD-ROM Mode 2 - data discs
CD-DA audio discs
CD-DA/ROM - Mixed mode/combined
CD-ROM XA and Photo CD (Single and Multisession)
CD-Bridge (White book, Video CD)
CD-I, CD-I ready
The cabinets are 17" but with ears for std rack mount, 7 inches high, depth
behind the rack 20 inches.
Anyone (local) want some? Anyone got any ideas what to DO with them?

I'm having a ton of trouble saving a program on a cassette tape using
Altair 680 basic. Was there a KCACR basic made without the CSAVE
command? My basic appears to have a CSAVE command, but it won't accept the
name!!!!! : (
I'm sending this to two groups. I've been at this problem for hours
now... : (
I'll post a transcript below. Let me know what I'm doing wrong! : (

Yes, I'm replying to my own message!
I did a quick search on google and came up
with 300 links (searching for "Exatron Stringy
Floppy").
Unfortunately, I was unable to confirm what
the ESF's were made of. The sources also
state different increase read/write rates
over cassette drives. Here are some of the
better links (including pics of the unit and ESF):
