I need to move some data from Wang 5.25" VS15 diskettes (OS ver. 6.43.20) to
ASCII. Is there anyone who'd like a project? I'm not sure at this point how
many diskettes there will be, but generally these projects run around 15-20
diskettes.
TIA,
David

Having a bit of cabin fever Sunday I convinced my wife (well, not really...
she likes foraging as much as I) to go thrifing. First stop in Stockton was
the the college parking-lot flea market (never know what you're going to find
there.) I was almost empty-handed when I found a a bin of 16 Atari Carts
(actually 15 I later discovered as one was missing the guts) paid $5.00 for
the lot. Included were few standards such as BASIC, Star Raiders, Defender,
and Asteroids but also Atari Assembler, a Dealer Demo Cart, a couple word
processors, an "educational system master cart" (networking??? Pilot?) etc.
Pretty good find. Still need to test em.
Another item, an facinating BASIC book, "Elementary BASIC", a BASIC
instructional guide using the Sherlock Holmes character (from the texts of
Dr.Watson), in it Sherlock Holmes solves a few cases with programs ran on
Babbage's Analytical Engine ('translated' to BASIC by the authors). Pretty off-beat.
The last stop was to our favorite thrift store which did well by us again, I
picked up an Apple IIc (sans power supply) for $3.98, and a really nifty item,
a Sharp PC1501 Pocket calculator w/printer/cassette module (CE-150) in its
carrying case with some cables (no ps for these either) for $4.92! Tested the
handheld, it works, even though the batteries I removed were drippy; the
expansion unit I have yet to get working (not enough power from the adapter I
guess??) There is also a cassette tape in there, will be fun to check that
out. The Apple will have to wait till I find a PS unit, since it is my first
8-bit apple unit. I have little for it but the computer, a users guide and a
few loose disks picked up here and there. I figure I'll collect some of the
games I thought were cool for it and maybe a gizmo or two. Ahhh Another
beginning, will be fun to discover a tidbit here and there, as finding the
Commodore oddities are getting harder to locate.

That, of course, doesn't make it any less dee-lightful. Now, if I could

Anyone tried the lastest DR-DOS by Caldera? Just curious how good it
actually is especially on older machines. Saw a write up proposing that
obsoletes may become viable resources again using DR-DOS but at present
I haven't had a chance to download the trial and run it on a 286. Im
sure someone here is deeply into it.-

What a coincidence! I just bought 3 monitors, 4 boxes, a small stack of

Haven't had a chance to even look them over yet, not sure what's in them.

Same here. Anybody. And I'm in need of software and a monitor cable as

Hmm. Had no idea they were worth that much. I paid $120 for the four
computers, three monitors, and manuals. Had to sell one of them so that
I could afford more stuff! I also came home with 8 Mac IIci/IIcx's and

This is n response to your site asking if anyone has TRS-80 Model III
computers to sell. I have one I may be interested in selling. It has
never had the case open. Also have a wide carriage printer to go with
it. E-mail me at srayner(a)erols.com with an offer. Thanks. Steve
Rayner.
I've been tinkering with my Kaypro to try to eliminate the errors that drive B
has been giving me. Putting in a new floppy drive didn't seem to fix them;
I wonder if it's the cable? (As is, the Kaypro supports two drives (SA400 or
equivalent). The original owner bought a little hardware thingie that does
something to the drive-select signals to add support for four drives; he also
added a connector to the cable for drive C between A's and B's connectors.
I currently have no drive C, and only drive B is giving me problems -- that's
why I suspect the cable.)
So I bought a new cable. It has that stupid half-twist, so I'm wondering how
to coax my system into working with the new cable. I think I understand the
situation from the point of view of the drives (both drives are jumpered as
#1, and some pins are exchanged: 10 <-> 16, 11 <-> 15, 12 <-> 14).
But doesn't the computer have to cooperate in this farce? That is, would I
have to reprogram my BIOS to mess things up in the same way as the IBM PC's
hardware, so that the drive cable can do its part and thus it all ends up
(sort of) working?
It's worth trying the new cable (though it seems rather cheap, and there's a
break in the insulation, though that could be because I dropped it on a
concrete floor at the store). But if it's too much trouble, I'll skip it.
Incidentally: God damn IBM for cutting corners this way, and making people
think shenanigans like this are totally normal and to be expected, and messing
with a perfectly reasonable interface.

Yep, that sounds about right. It uses the same power brick my GRiDPad 1912

I'd rather trade it to someone who can really use it. Even if it works, I
don't really have a use for it, and the 1535 w/8mb is a very usable machine
even without the tray.
GRiD 1535 BIOS Date: 1989, slightly under the 10 year mark, but these are
such extrordinary machines!

> A few questions about clean(ing) circuits:
> a)Can dust cause any damage to a PCB? Can it short anything?
Yes and No - no direct harm is done, but dust turns out
to be a good insulator, so the core temerature of the
chips rise if they are covered by dust - even a small
dust film can be difficult. Higher core temperature means
higer stress, more aging and sooner irreversible failure.
> b)What do you recommend for cleaning out PCBs if there's lot of it,
> or spiderwebs, mold whatever?
Yes cleaning is a must. I use several methods:
1. If the board is small enough to fit, I use an ultrasound
cleaning device. This method is not usable if stickers
or other non wter resistant markings ar on the board
(and should be keeprd intact). ultrasound cleaning removes
anything in less than a minute.
2. If the board is to big i use oridinary water (but destiled
is prefered to avoide calcium (?) stains). Maybe with a
little soap in front.
3. If there are some stickers to preserve, I use only short
'splashes' of water, from a mouth washing device.
Alle three methods requiere intensive drying. So I first
use a soft (frotee) towel, and then wave the board to dry
of thebigger parts. If the board is very crowded (like a
IBM-PC or XT) I will use a centrifuge (spin dryer). The
board has to be fixed to get the right. Also a hair drywer
for blowing _cold_ air is usefull to drive out the water.
I never use warm air, since it is less efektive and leaves
more stains on the surface. But as I said, using destiled
water makes it less cruical when it comes to drying.
Also 'canned' compessed air as available in some shops can
be used to drivew out the water from deep corners.
You don't have to remoe all chips.
4) Now if I can't use water, I thake several soft towels
(fabric) and rub off the dirt. A sponge with a liite
soap water, and a second one with clear destilled water.
Also a stick an linnen is usefull to remove dirt from
the edges.
The ultrasound method can be used for a lot of parts.
Even sonme keyboards do well - Original PC-Keyboards
could be dumped without any preperation into the water
and cleaned in just a few seconds.
Oh: NEVER USE ANY CHEMICAL CLEANERS (beside _pUre_ soap)
ON YOUR PCBS - NEVER - NEVER - NEVER.
> c)Does distilled water cause rust?
Basicly almost no, but after touching thesurface it
isn't destilled water :) The main reason for rust
is high humidity always dry your precesious little
ones and store them not in an swamp like climate
(sorry if you live in FL or somewhere near the
Amazonas).
> d)Can distilled water be used to clean circuits?
Yes - see above.
> e)As I understand, tap/spring/rain/etc. water is full of minerals
> and that's why it's conductive as well as rust-causing
Yes/no - If you dry them, they won't pick up rust.

Thats the problem with Microsoft - They always want to
pollute the environment - and as we see not only the
Internet or Java, even simple helpless Apple Disks are
to be transformed in non standard monsters :)
Normaly I could suggest just to dump them since most of
the software is not very unique. But again here are
several levels of restauration:
1. If you only want to keep the software:
Rip of the cover, clean the disk with cold air and / or
alcohol (no nor brandy - use isopropyl alcohol) - take
a _clean_new_ linnen and pour alcohol on. now go soft (!)
ofer the disk to remove any parts - try to 'roll' the
fabric to change the surface and lift of the mold.
now place the disk into a new cover (always open only
one side). If the disk wasn't damages itself you now
should be able to read the content and duplicate it.
I used this Method several times in data recovering
actions.
2. I you just want to keep the cover (special print, or
just since it is an genuine early Microsoft :):
Take a sponge with warm destiled soap water and sponge
it down (Never look at the disk ... it's a shame :).
Drying and now storing a at a dry place to prevent the
mold to come up again - Mold doesn't like dry places to
flourisch.
3. You want keep both:
Combine one and two - so you have a funktional copy
and a displayable disk. Or just use method 1 and transfer
the label to the _new_ copy.
4. You realy want to keep this disk (worst case):
Forgett it - at least You have to do it like in 1) but
you'll have to open the original cover _very_ carfully
clean the disk, clean the cover AND replace all this
fabric fleece inside the disk for new fabric - thats
_very_ sifficult - and even if you mange this, the
disk well always look damaged. The possibility of
reinstaling mold is also the highest.
Some tips:
- Never use Mold covered Disks - or if you have to,
restrict the usage to on 'mold-only' drive.
- Don't use disks lying next to moled disks - the little
friend is already there.
- Store your disks always dry and with enough air
circulation.closed cases can be deadly to your
Disk.
- Avoide high humidity
- Avoide low humidity, since the fleece will become
damaged.
- Avoide heat - Some disks could start to loss their
data as soon as 60 degree (140F)
- Avoide cold - Never use disks below 10 degree (50F)
the stress results in higher aging (remember, flopy
disk drives are still cutting tools like a turning lathe)
Also the magnetic film will loose the tightening if the
temperature is to low (same as when to high (>80 degree 180F)
I already dumped several hundered Disks I recovered
previously from basements and garages because of
Mold.

I tried it when it was OpenDOS. It's just like MS-DOS with a few

You can still use the task swaper, though.

it all. Midi is not fast enough to sample/reproduce straight a/d or d/a
