--- Now to the rest:
I'm wishing I've kept all the broken TTL chips over the years...
I am evaluating a TOP2004 programmer for testing TTL chips. I bought
it off of ebay from
http://www.mcumall.com/comersus/store/comersus_dynamicIndex.asp I
bought it on ebay because the price was cheaper. They are located in
Canada and it took 5 days to get shipped to Alaska. Very well
packed. The other TOP programmers ship from china/japan.
I want to be able to recommend a TTL tester to my customers of the
Kenbak kit. With 132 74xx TTL chips it would really come in handy!
So far I think it does a good job. If I lift a signal leg on a
74LS04 it both can't auto detect anything and will report a 7404 as
bad. I only have one known bad part, a 74LS376. It DID report it as
bad and undetectable.
What I'm wondering is if anyone knows how I can prematurely kill a
TTL device or simulate static failure. I'd like to try to test how
thoroughly the programmer tests the chips. It can't tell the
difference between a 7410 and 7412, but that isn't too important for
knowing the chip works (mostly)
On a second note, I have successfully over clocked my Kenbak
500%. Its running happily at 5MHz. : ) Although it gets a lot
hotter! I need heat sinks...
--I suppose giving one 12v to simulate hooking up a power supply wrong?
--Hooking 12v to a device normally powered at 5v?
--Shorting out a buffer output? (I think some buffers are designed
to be shorted out though)
--Vehicle ignition coil to an input? : D

I'm sure you hate this question, but did anything ever happen with Don
Maslin's disk collection? I spoke with and exchanged disks with Don over
the years and just tonight learned of his death.
I'm looking for the MS-DOS 2.11 bootdisk for the Sanyo MBC 555-2

It is assumed to be lost.
Parallel efforts are ongoing to build collections from
what survives in other sources.
Sadly, a dozen book boxes of 8" disks that I gave him when I didn't
have the time to do anything with them are gone as well. Fortunately
the really obscure stuff was already read from the set.
Hi,

On an old Spenser Tracy, Kate Hepburn movie called "Desk Set" playing
on the Family Movie Channel. 1957
Looked like an IBM 700 series computer. Unfortunitely it was only
shown during the opening credits.
Story is about installing an IBM computer in a TV Studio. Mostly a
situational comedy. I am not sure I will stick around toii see if it
show up later.

We have a bunch, as in too many to count at this point in time, of 9 track tapes and the free standing tape
racks they are hanging on, to dispose of over the next few weeks. I will putting a few on ebay along with
other stuff as it gets sorted out what has and has not been spoken for.
Mucho thanks to those to all of you who bid in the ebay selloff. All involved conceder it has been a
success, and IBMcollectables now has a TrueBlue xSeries quad Xeon with twin RAIDS, it is not NEW but it
is a whole lot more computer then the 1850R-400 it is currently crawling along on. I hope to get Gallery 2.x
loaded and SQL loaded so I can get the site updated and moved over soon.
Oh ya....I digress
... as for the 9 tracks and racks
Question One: anyone interested in picking things up here in Columbus, contact me offlist.
Question Two: anyone know of any use for 9 track tapes ?
Question Three: what is the "Green" thing to do with them, or do we let the local recycler take them all ?
PS: we have 4 3350's spares and two 3420 Tape Units (spare / parts - mostly complete but not working),
and , some card cabnets currently not spoken for. Please contact me off list.
Have a happy weekend everyone,
OSU WON ! and that school up north just LOST !

would be difficult. These are wright-line freestanding racks without rollup
doors?
The computer muesuem was looking for some, but we were just offered six
at JPL.
> anyone know of any use for 9 track tapes ?
I have lots of tapes that have broken wright-line seals. If you can't find
anyone to take them all, I could use the seals, though it's likely you're
using the hard plastic auto-load types if they were used with a 3420.
Hi Tony
Well I got a good response to my musings re British Computers.
I'm busy cutting and pasting all of the data to give me a list of who
said what and who has what. A passing thought.. should there be a
British
Section at Bletchley?

Yes. The Dragon 32 was based on the same Motorola Application Note (for
the 6883) as the Tandy Color Computer, anf is a very similar machine.
Although for some inexplicable reason, the BASIC tokens are differnntly
ordered, so a binary BASIC program from a Dragon won;t load on a CoCo
and vice versa...
The main differece between the hardware of the Dragon and the CoCo is
the printer port. There were 3 PIA lines left over once the necessary
signal had been taken for the sound, cassette port, keyboard, VDG
control, etc.
As er all know, the CoCo used them for a bit-banged RS232 port. On the
Dragon, they were the Strobe, Busy and ACK lines of a Centronics port.
The data for that came from the 8 keyboard scan lines (one port of a
PIA), suitably buffered. There was no problem with the dual use of this
port, the machine didn't try to read the ekybaord inptus when it was
sending a character to the printer, and the printer ignored the keyboard
scan 'data' because there was no Strobe signal along with it.
The Dragon 64 has (not surpisingly) twice as much RAM, and also a real
hardware RS23 port, based IIRC on the 6551.

HP9000 K class box with 2 jamaica arrays and 2 autoraids
all of which is mounted in 2 beautiful, 1.6 meter HP cabinets. All cabling
is included. Disclosure: One Autoraid has a bad controller. Several of
the drives were upgraded in one Autoraid to 36 gig drives. Besides the
one bad controller in one autoraid, all the rest is working.
Contact me offlist if interested. Gear is located in St. Louis, MO. I will
not store this for you ;) Nostalgic interest - this is gear that I sold new
to this customer as an HP9000 dealer "back in the day".

Hi Patrick,
What type of computer are you trying to connect to? Mac, PC, a
classic micro, mini or mainframe? Which port are you using, serial or
parallel? Are you using a network adaptor box to Ethernet? I think my
DraftMaster MX has Etherbet built in, but as far as I remember, when
we had a prototype of the previous model, it used an external adaptor
box. I've connected plotters to Apple ][+, Apple ///, Lisa 1, Lisa 2
and every type of Mac, and if you need a plotter driver for a Mac my
company can still supply one. Its not the connection that's
difficult, often its that your application does not output the data
in a format the plotter understands. Modern machines usually assume
the data is going to written into a pixel map (either within the
printer as with PostScript, or within the host computer) so that
later geometries can partially obscure earlier ones. It is even
possible to print from programs like PhotoShop, but it really works
the plotter hard, and while runs of a colour are fine, and single
dots come out with fibre pens, ball pens rely on movement to get the
ink flowing, so can't do dots. Draughting(drafting if you're over the
pond) pens are another game entirely.
I am replying to the digest, so its possible someone's already
answered this.
Roger Holmes.
I've been working on the mail gateway that sits in front of the classiccmp
machine, just a test to make sure things are going the way I expect.
No reply needed.

You can tell how often I fire up the 3CT, because this is probably
general knowledge.
It looks like UCLA AIX archive is being taken offline. Don't know about
existing mirrors at this time, but if you want it now's the time to get
it (before September 4).
Would someone here be interested in a Timex Sinclair "Power Pack 1" tape?

Q: What is the most annoying thing in e-mail?
All:
While thumbing through a folder of random stuff, I found a hand-drawn
map of what appears to be ?Adventure?. I don?t know enough about the
differences between the point versions to confirm which one this goes to.
Here?s a link to it:

Can anyone positively ID this and give me the background for my Web

Hi,
As you recall, I am working on a Catweasel for
NorthStar floppy disk reader project. It is slowly
making progress and will eventually come out in the
open. I'd still like anyone who can to join me.
In the meantime, some people have said one of the
problems with using the Catweasel is actually finding
one to buy in the first place. I have had a lot of
luck here:
http://www.ggsdata.se/PC/en-iokort.html
I recently bought a Catweasel Mk1 from them which
prior to finding it I had thought those were
"unobtainium".
Please do not misinterpret this message, it is not a
SPAM message as much as an little help to my fellow
NorthStar owners to get in on the Catweasel fun. Now
you can longer say that you can't participate because
you cannot find a Catweasel!
Best of luck with your NorthStars whatever you do.
THANKS!

PS, I am on vacation and may be a bit hard to reach
for the next few days.
Hello,
I need some help about the board Model 5400, ASSY00060-13 REV T urgently. Can you send me some technical documents(if you have any) about this board. Do you have any information about that if I can get an extra board from the producer or not ?
Does anyone else have an AP-64e EPROM writer card for the Apple ][? If
so, is there any way I can get you to dump the ROM and send me the file?
I have two of these: one is missing the ROM and the other has the ROM (a
2716 EPROM) but it has been erased apparently.
Also, can you write a tutorial on how to use it? The manual is available
online as a PDF:
http://www.apple-iigs.info/doc/fichiers/ap64eprom.pdf
...but the Engrish in which it is written is so mangled it's hard to make
out what it's saying. Plus, it excludes certain key documentation, such
as which side is "on" for the programming switch, and the DIP switch
setting chart doesn't define what 'x' and 'o' mean in the context of the
switch settings.
Thanks!

No, the OPL was a Sinclair QL..
The microfile 1000's I used were about the size and shape of an
original IBM XT, but with multple serial ports on the back rather than
pc style screen/keyboar: You connected up dumb terminals to use. We
ran BOS on them, but think they were intended for ConcurrentDOS.

>From time to time, I run across panel meters, at hamfests, in the
dustbin, whereever. I'm sure, in most cases, they still work, but
without pinouts, it's a bit tough to put them back into service.
The latest one I have is marked with the following...
Fairchild Panel Meter
Model Number 300555
5VDC Powered: 2V F.S. Range
7825 (in paint, presumably a date code)
It has an 11-pin connector on the back, and inside, under the red
plastic cover, is 4 7-segment LEDs, som resistors and caps, plus 4
black, unmarked epoxy blocks I can't identify. There are a number of
traces going under each one, so I'm presuming they are bare dice that
were glued to the board, then encapsulated, but unlike modern examples
of that practice, these are in square-sided epoxy blocks.
I don't need to know the entire circuit. Mostly, I just need to know
where to attach Vcc, GND, and the sensed voltage. Obviously, googling
for "fairchild 300555" turns up nothing. Not at all unusual for
something of this vintage.
Thanks for any pointers.

I would be surprised if that did work. There are some hardware
differences in the 100A and 100B. The graphics hardware is slightly
different, and the quantity of memory on the motherboard is different.
I'm sure there are also more subtle differences which I didn't mention.
Anyway, it proably wouldn't work, but then again, I've never tried.
There are also other differnces that have nothing to do with the firmware.
The 100A used an AC fan, while the 100B used a quieter DC fan. The 100A
power supply was not quite beefy enough to run the big hard drives,
although it would unreliably work. The power connector on the 100A for
the second drive was also excessively short so it wouldn't reach the
standard DEC hard drives alone anyway. Usually, 100As have the block
letter logo on the front, while 100Bs have the script Rainbow logo.
