Archives now go back to 1999

Hi guys/gals,

The list archive now goes back to 1999.

http://dir.gmane.org/gmane.comp.hardware.trs80.model100

I don't think the index is fully built out yet (so searching for TPDD
will only bring up recent articles at the moment) but that should happen
automatically, eventually.

Re: Setting up a TPDD

Bingo!

I got it! Well you guys got it for me.

I dug out some old DSDDs which were hiding in the dusty corner of my
computer desk (I didn't even know I had them anymore). Transfered over
DOS100.CO and DOS100.BA. Bada Bing Bada Boom formatted the disk and off we
go, a working TPDD drive.

I thank you all for helping me out on this.

Now I have one other question which ROM should I buy so I can properly use
my drive. TS-DOS vs Ultimate Rom. I'm leaning toward the Ultimate ROM myself
because other utilities (which I guess I just answered my question).

6v dc ... negative center!!!  The same power supply specs as used on 
a Model 100, 102, 200.

>Does it matter what type of floppy I use?

Yes.  The high density ones are ... too good!  Use SSSD (single sided 
single density) or DSDD (double sided double density) if you can't 
get the first.

Re: Setting up a TPDD

Well I have made some progress.

 Using Ron's guide which Rick provided the link too. I was able to
successfully able to get the TPDD to spit out the correct code ( q{ ).

So after that, I tried TEENY again. The motor that drives the belt that
spins the just doesn't spin and no indicator lights come on. So I see the
motor is labeled 6VDC. I figure I would see if the motor is burnt out and
hook up a 6 volt source to the motor. It didn't seem to spin, but I gave
TEENY a 2nd shot to see. Success (sorta)!

Now when I prompt TEENY to save a file off the 102 the plater spins and the
read/write LED comes on. With the cover off I can see the head move back and
forth just a couple of millimeter or so.

But then I get the FF error. Which means if I'm correct that the file can
not be found on the 102. When I hook the 102 to my linux box running dlplus
I can save and load files no problem.

I'm either doing something wrong or my TPDD is off to a better place where
all TRSs go when they die.

Does it matter what type of floppy I use?

Thanks again everyone for you help. Sorry if I'm a little slow.

Re: Setting up a TPDD

Hi Keith ... thanks for writing.  Below are some links to answer your 
questions and get you going.

If you need a boot disk, these are always available from the Catalog 
and Order Form at Club 100 (www.club100.org) for only 2 bucks.

If you have the ability to transfer files between a PC and your Model 
102 or 200 then you are already set up with a Model "T" dos, like 
TEENY or TS-DOS.  If not, then download the DL-ARC.EXE self-deARCing 
file at http://www.club100.org/catalog.html#hotsetup and get set up 
for file transfers to a PC.  During the process you will load TEENY 
... part of the archive.  Also in the archive are dos100.co and 
dos200.co ... these are RAM versions of TS-DOS for the 100/102 and 
200 respectively.

There is also a BASIC DOS called DSKMGR.CO (disk manager) which is 
found in the Club 100 library DRIVES 
category  http://www.club100.org/library/libdrv.html

Booting instructions, as well as drive belt changing instructions are 
here: http://www.club100.org/library/libsup.html

Now ... the BIGGIE is testing the drive without a dos ... the amazing 
Ron Wiesen provided those instructions here: 
http://www.club100.org/library/libdoc.html ... see the heading 
"Diagnostic & Diagrams"

That's about it for now.  Good luck and congratulations on 1) getting 
a Model 102, and 2) posting a question for the first time.  That's 
exciting, sir.  -Rick-

Setting up a TPDD

Hello Guys,

I'm a long time lurker, 1st time poster. I bought my 102 a few years back
and a model 200 more recently. I'm only 25 but I remember see one on
Discovery Channel in the late 80's or early 90's and I wanted one. So now I
have two. It sat on my shelf for a long time.

Well just  the other day I got a TPDD.  Eject mechanism hadn't been used in
a long time and was stuck but I managed to fix that.

My question is how can I test the drive to see if it works? I see I need a
file call FLOPPY.CO and that I would need to boot off the disk. Where can I
find this file and how to I get it onto the disk. Can I take a regular FAT
formated disk and just copy it. I doubt it is that easy. Or is there a image
out there I can just use "dd" to blow on to a floppy.

Thanks ahead of time guys.

magic pokes to make things disappear

TEXT: poke 63841,0

ADDRS: poke 63874,0

SCHEDL: poke 63885,0

To restore them, poke the value B0  (176 decimal) hex instead of 00.

while I'm on the topic..

way off topic, however... one of my favorite videos.

http://www.youtube.com/watch?v=Y1gcvHBd7oc

have to share this video.  Here is the background info.  A few years
back sailboat design really took off, literally.  The combination of
carbon fibre for high strength in both hulls and masts, and a new idea
called the "canting keel" has created some incredible performance on
the water.

I know most people are not sailors, however I hope it's interesting.

There is a round-the-world race sponsored by Volvo, and the current
class being raced is called the volvo open 70.  These boats are
capable of >40 knots under sail in the open ocean.  This video
focusses on one of the boats "pirates of the caribbean" as it pulls
out of south australia and heads out into the southern ocean (the
roaring 40's).

I find it interesting to watch a 70 foot sailboat surfing at 40 knots
in 10 to 20 foot seas, although I am sure I would not be up for the
ride. 1 month of constant firehose in the face....no thanks.

What makes the southern ocean especially challenging, is that at these
speeds in those kind of waves, it is really hard to see "growlers",
which are mostly submered small icebergs.

Oh yah, it's made of carbon fibre and honeycomb core, but it's a bit
larger than my project!  Hah.

my vacuum controller project

Well, almost done.  It's up and working now, and I had loads of fun in
the process.  To use the M100 as a controller, as I've mentioned I'm
using the BCR port to power a vacuum sensor, and take the readings.
Originally thought to use the printer STROBE signal as an output, but
that does not work.  I changed the plan to use the casette port relay
instead, and that works great.  I used an old modem cable to connect
to the cassette port, and to make the specific wiring I needed.  The
casette relay drives a signal to an external relay board that has a
relay capable of switching 120V 15A.  That relay sends power to the
vacuum pump.  My 555 circuit to convert DC voltage from the automotive
MAP sensor, to a frequency, worked well, however it is not linear.
So, I had to use a lookup table to correct the non linearity of the
sensor.

The coding was so fast and easy...I'm surprised I did it.  Usually I
have a lot more pain.  I had the M100 in the test set up, with a REX
installed with TSDOS.  I could compile assembly and directly load and
test the changes, which made for very fast iteration.  Overall the
software is simple.  I use function keys to vary the two setpoints up
and down.  The setpoints represent the vacuum at which the pump either
needs to switch on, or switch off.  In effect, they are the max and
min vacuum settings.    I simply loop quickly looking for either
inputs from the keyboard to adjust the settings, and make vacuum
readings, and decide what to do with the pump.

I've got the entire rig mounted in a wooded case that has 120V AC in,
vacuum in, and a relay controlled 120V outlet for the pump.

This is the first application that I had originally intended to be my
use for M100s - controllers.

Every Menu File Slot Consumed in M10x Laptop

Field Day 2008 will be a bit different than my past Field Day efforts in one
respect: I will operate on every HF band allowed by the Field Day rules, and I
will employ every allowed mode of transmission.  Consequently, in the
particular M10x laptop that I'm dedicating to handling the logging chore, use
of the "Log Recorder for Model 10x" will consume every menu file slot.  It's
an interesting "maxed-out menu" situation where the Model 10x has just enough
file slots to meet the demand -- no file slot remains unused and no additional
file slots are needed.

As is the norm, the first 5 file slots are consumed by the built-in
applications (BASIC, TEXT, TELCOM, ADDRSS, and SCHEDL).  All of the remaining
19 menu file slots are consumed, as the menu depiction below illustrates.

| BASIC     TEXT      TELCOM    ADDRSS   |
| SCHEDL    LOGREC.BA L160CW.DO L160DI.DO|
| L160PH.DO L80CW.DO  L80DI.DO  L80PH.DO |
| L40CW.DO  L40DI.DO  L40PH.DO  L20CW.DO |
| L20DI.DO  L20PH.DO  L15CW.DO  L15DI.DO |
| L15PH.DO  L10CW.DO  L10DI.DO  L10PH.DO |

The BASIC program file of the Log Recorder for Model 10x, file LOGREC.BA,
consumes 1 menu file slot.  The 18 remaining file slots are consumed by log
files that are needed to cover all combinations of the six HF bands (160, 80,
40, 20, 15, and 10) and the three transmission modes (CW, Digital, and Phone).

Currently, the Field Day rules do not allow use of the 60 Meter and 30 Meter
bands.  Perhaps the rules will change in future years.  If so, and recognizing
current FCC restrictions on transmission modes for these two bands, then an
additional 3 log files would be needed: L60PH.DO, L30CW.DO, and L30DI.DO.  In
order for the menu to support those additional 3 log files, the file slots of

Solstice Point - Summer in Northern Hemisphere/Winter in Southern Hemisphere

According to calculations made by my Model 10x laptop, next week, at 23:59 UTC
on June 20th, our planet reaches one of the two solstice points along its
orbital path around our star.  This particular soltice point marks the middle
of Summer for folks living in the Northern hemisphere, and the middle of
Winter for folks in the Southern hemisphere.

Enjoy the season wherever you live,  -= Ron Wiesen =-
