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.

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

Hmm. Had no idea they were worth that much. I paid $120 for the four

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

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

Serial Card. But the //c will read CP/M files only in RAW
mode - so any nibble copy programm (or even RWTS programms)
can copy CP/M disks from DOS (>3.2, 16 Sector DOS) or ProDOS.
If you want to copy CP/M files logicaly (I think thats what
you need for transfer) you could only use the CP/M environment.
The best way is to put a SSC in an ][, ][+ or //e boot CP/M
and use MODEM7 for Transfer (and _ANY_ programm on the PC :)
You could also use any other serial card, if it is supported
by your CP/M - But its hard to find anything not SSC compatible .)

FYI I have a vinyl of early computer music some of which was rendered in
such a way as you describe. I picked it up at PCC'76 or maybe 77.
Back then there were a lot of different efforts to render computer music.
Some were quite interesting but the best of the day was from the people
with the blue boards that called themselves SSM or Solid State Music.

Wasn't someone looking for Vic 20's for their collections? (Dan???) I'm
sure this person will part out what they have even though they think
they may be able to get a package offer. Contact them at the Erols.Com

We currently own six C64 computers, seven 1541s, two C128s,
two Vic 20s, several monitors, Amigas, printers, etc. and
would like to know who to contact regading selling all our
C64 and Amiga equipment. We have tons of games and mag-
azines also. All are in great condition (some never used).
We would like to clear out our playroom so would prefer to
sell everything all at once and not one piece at a time.

does anyone have any experience using hardware copyright keys? I picked
up a couple copies of some software from a thrift shop today and some of
them ask for hardware keys- the most info i can find is something about
serial card plugs? It didn't have them in the box, and I couldn't track
down any info on who donated them. am I completely out of luck ? It
seems to me that I would have to buy a whole copy from the original
seller of the software, but I doubt they're still in business. any info?

More like 100+, not counting all the addressing modes. the instuction set
for the 8086 is many times larger than the PDP-8. The PDP-8 instuction
set is 47 (most all variations included), it's very minimal.

Actually there was DECnet-8! Dual processor machines were not uncommon.
but they were not networked like you would current machines. It was not
the mindset of that era and generally not required.

If you want to go the underground route, there are cracking programs that
defeat the hardware (dongle) locks on some programs. But I'm not suggesting
that you do it or anything.

The main problem with these machines is that they are still so heavily used that noone wants to give up the media (cd-roms, etc). You can try comp.sys.next.marketplace. There are also some websites... http://www.orb.com and http://www.deepspacetech.com.
Mostly what you probably need is a >300 mb standard SCSI harddrive, a cd-rom player that works with that machine [there are many but not all work] and the cd-rom media (NeXTStep 3.3 is probably the best).
If you were near me I'd tell you just to come by and I'd do a builddisk for you. Perhaps someone else will offer. $25 was a good deal- last time I checked they were still going for a couple hundred. Poor kid!
Once you get it working there's tons of software around for it, some of it the best quality available... try http://peanuts.leo.org and http://www.peak.org/next.
The machines, although great performers for their time are getting slow by today's standards. Because of that, and the fact that Mac OS X Server (aka Rhapsody) is somewhat available, the prices should be dropping lower.

Do you mean compilers (I think DR was the only one to do PL/I), or do
you mean application programs for an 8086 that used PL/I? I used the DR
compiler to do a sports handicapping system and a mailing list system.
It used DR's Acess Manager for the ISAM file system, and DR's Display
Manager to draw forms on terminals. It ran on an 80286 based Concurrent
DOS (aka MP/M II) custom built S-100 system. I believe I still have the
source code somewhere, if that's what you are looking for.

First of all, I believe it could be untwisted by pulling off the
back cover of the connector and pulling the cable off. Also, I
believe the IBM controllers walk fine with jumper-selected drives,
just that everyone uses the half twist thing.

I certainly do not want to propagate any more off-topic stuff, so
maybe e-mail would be mo bettah.
Having said that: The Model III that I have was used primarily for
R2D2, some of the ancillary robot, droid and creature noises, and a
lot of the tracks for the Alien Roadhouse Band, etc., etc. Thus I
was told by the previous owner, and corroborated by one of the
editors who worked on the pic.
Csound *is* in the digital domain, but it's output needs to be
made into a voltage somewhere; the early PDP11 versions used the
DACs of the day... in fact MUSIC IV was used entirely offline, one
coded the program, punched cards, waited until the (lowest-priority)
job was run [to tape], the the tape(s) were taken to another
facility to be rendered through DACs to am analog recording. *Then*
you debugged...
Zane, I would like very much to have an (archival only, honest!) CD
copy of the Hyman recording.
BACK ON TOPIC PART: I would love to locate some 70a vintage DACS,
prferably standalone boxes, or more DAC cards for my MINC. I am
trying to consolidate all the info/software/hardware I can around
the DEC Mini line and music. I have a wonderful picture of a PDP-5
system running a music notation and translation interface for MUSIC
IV at Bell Labs in the late 60s. It then sent code to an IBM 7094,
which output a tape to another machine, referred to only as a "PB
250 Computer" [Pitney Bowes?] [Packard Bell?] which acted as the
translator and DAC. I have soundsheets in the book of music
realized on this machine, and I'll put them up on my FTP site any
day now... (Thanks to Marvin, from whom I stole the book)
Damn, drifting off topic again... sigh.
I guess I should output a list of my collection....
Nah, too bleedin' hot right now.
Cheers to all
John
< Help? I have 2 power supplies for DEC BA123 boxes which

Don't ditch the failed supplies. They can be hard and expensive to

that takes the internal fuse. Open with care as the caps in them can
hold a lethal charge. Rare is the failure of the caps from what I've
seen. The high voltage chopper transistor or the input rectifiers are
more likely to be suspect.

When I was at WPI in the mid-70s, I got a chance to work with the
Arp AX and Odyssey (and a few others for which I forget names) to
produce some music which was used in a theatrical production on
campus (Beltold Brecht's Gallileo)...
I loved getting chances to work on those things...

About a decade ago, a few friends of mine and I played with some
pdp-11 controlled music generation. We got a bunch of the TI
sound generation controllers and one person (who was adept at
IC circuit design) designed us a circuit for controlling a set of
these units from a DR11C (16-bit parallel output).
I still have one prototyped at home... it allowed up to 9 voices
(three voices/chip, 3 chips) of sound, and 3 voices of percussion.
Someone else got ahold of the Stanford music software for the pdp-10
and wrote a pdp-11 version of it... we had it playing a bunch of
the old stanford songs, and I entered a few more (like Scott
Joplin's "Crush Collision Rag"). Since the hardware connected to the
AC lights of the -10 was called the MK10, we called our board the
MK11...
Somewhere I have the schematic for it...
Later on, another friend (hi, Allison) designed a DLV11-J to MIDI
interface... I have a couple of Casio CT101 synthesizers and a
sequencer...

'Moog' is not the kind of music ("Hey, let me put on some moog music."),
rather it is the name of the inventer of the synthesizer.

< A few questions about clean(ing) circuits:
< a)Can dust cause any damage to a PCB? Can it short anything?
Yes, it can be conductive, block cooling and host molds and fungi.

Vacuum with a conductive (carbon/plastic fiber) brush.

Rust is the product of oxidation. Air is the culprit. Water _may_

Yes.

I've recently gotten the necessary hardware and software together to
transfer Records (16, 33, 45, and 78) to CD. As part of this I was digging
through my parents Record collection and found a record that is Moog music.
It was something I was looking for, as it was so unusual that I remember
when my dad brought it home over 20 years ago.
Anyway I was wondering if anyone knows anything about what kind of hardware
was used for this?

anyone have a suggestion for where i might come across a ~20mb RLL
drive? 3.5" size, don't have the model #'s on me at the moment although
I recall with the toshiba it was a JVC. seems to me from what I could
pull off the net that these drives seem to die often.

Ok, this is a repost since the original responder had to back out for
whatever reason...
I have some excess Zenith Z248 equipment to get out of my way and
would prefer a trade of other equipment for
these..
I have two ZDS ZWS 248's, these are the planar units that the
286-12 processor board plugs into. Complete
main units with the planar board, power supply, cpu board, I/O
board HDD/floppy controller (MFM), MDA
video card, drive bay inserts, etc. You need to add drives and it
will take any drive from 360k to 1.44m. It takes
all sorts of MFM hard drives as well and can probably accomodate an
SCSI or ESDI in place of the MFM
controller which will allow larger drive types. 512k on the cpu
card. They have two open 5.25" bays, one has a
filler that can be removed.
There's also another identical unit without a power supply. It's a
case, planar board, drive bay inserts, 2 I/O
boards. Mostly for parts or use to build up with parts you find
elsewhere.
I need $25 plus shipping for ALL THREE (as a package) or will trade
for something that I can use such as
cdroms, hard drives, SIMMs, microchannel adapters,etc, etc, etc....
I would really like to get a couple 2X or
higher SCSI cdrom drives, caddy type or tray load or larger SCSI
hard drives whether full, half, 5.25 or 3.5"...
Drop me a line if interested. I also have two ZDS memory cards that
work on these to bring the 512k up past
1024k that I would like $10 each or trade for. They are not open to
sale/trade until the other units are gone and
the new owner decides they don't want them.

are there hard drives for laptops that are smaller than the 2.5"
