I am amazed that there isn't a standard for remotes -- 01 for on/off, 02 for
VolUp, 03 for VolDn, etc. But of course, nobody listens to me.

As I recall, there was much criticism of the IR keyboard since if you were
far enough away to make it useful, you were too far away to read the screen.

A 68040 -based machine is not that old, maybe a bit under 10 years. What I
was wondering is whether or not there is any objective advantage of old
machines to new ones. F.E. one could get an old IBM mini (System/3X) for
little or no money, but is there anything doable on it that is impossible to
do on a W****** 95 machine?

Greetings all!
I recently received a ZX-81/TS-1000 (can't tell, the case was gone and the
TS-1000 is marked as ZX-81 on the board - doesn't matter anyway..)
It has a second set of ROMs, selectable via the channel switch, which
comes up as:
PLURI-FORTH BY TREE SYSTEMS
COPYRIGHT 1983
Does anyone know about this, or, hopefully, have a manual? VLIST tells me
the words but a manual would be really nice. I've since mounted the board
with homemade keyboard (which I didn't make) in an old Apple II case. Add
a few connectors on the case and I'm all set with a nice little 16k Forth
machine!

The EN drives are _not_ SCSI drives. You will need a controller card for them.

Would you like to have another IR keyboard?
Also, do you need any C64 stuff? I've been trying to get rid of it for a
while now (You name it, I have it, except the C64 and all kinds of expansion
boards/cartriges)

Actually I'm not current on the Rainbow and a few otehr would know where
the stuff is.
< Not being mini or DEC literate what is the RX50 format and what
<systems (platforms) is it used on ?
Basic RX50:
Single sided, ten 512 byte sectors per track soft sector and 80 tracks at
96 TPI for a total of 409kb formatted space per disk. It was DECs attempt
to get more density on low cost floppy. While the format worked the slow
dual spindle single positioner dual drive was a dog and internal pressure
made it's use manditory for many systems that would have gone with buyout
floppy drives like teac or sony. In the late 80s that would happen as
a result for the need for PC compatability (AT) and later lower cost and
more compact (3.5" 1.44mb).
The format is not half a 1.2mb drive as it's 250kbit MFM(same as 360k
floppy) and the spin rate is 300 rpm. It emerged whe DSQD drives were
being seen on CP/M-80 and the 16 bit systems of the time. Back then CP/M
could effienctly use a pair of 800k floppies cheaper than hard disk. DSQD
were 96tpi, 80 track 730->820k per drive and were essentially 360k drives
with 80 instead of 40 tracks. This format combo fell into disuse quickly
with poor acceptance due to the general chaos of 5.25" disk formats emerging
between 81-86ish. The driver of that chaos was the need for more space and
the still very high cost of then 5-40mb hard disks. The availability of
media for IBM XT 360k made it a pseudo standard.
It was introduced on the early 80s and used on most all DEC systems until
the late 80s when the VAXmate broke the mold by used RX33(1.2mb at
compatable) and later with 3.5" RX23(1.44)/24(720k) on the 3100 and PC
systems.

This is limted to ASR33s as they have the reader punch, KSR33 is keyboard

The answer is yes! Some systems have provision for tty reader control
and enables single character read. Others just take it at 10 cps as they
have all the time in the world between characters, it's not fast.

That connector/cable is used for a lot of things. It's mainly(?) for the
disk drives, but hooking up to the 850 gives you standard RS-232, multiple
atari SIO(is that what it was called?) ports and possibly a parallel printer
port? There were cables that had built-in adapters to go from the sio to
parallel printers as well as ones for RS-232. Also, there were modems that
used that interface rather than a standard RS-232 and printers too.
Sorry if that's not clear but it's late and I'm still working...

D*mn! Why can I find bargains like that! The Mac colour (or color for our

Isn't that the infamous computer that couldn't format disks? If not, what
was? I am not interested in acquiring this machine, but I would be interested
in the general specs
A bit area-specific but with the plethora of west-coast posters
aargh-ingly having access to so many old machines ; some parity.
Does anyone on this list know of any T.O. computer museums

Well, I have a TV, VCR, and Cable Descrambler box. Each has a separate
remote. I was unable to operate the TV picture controls for a while, because
each time I do, the Cable Box does something weird. Also, if I operate the
the volume control on the TV remote, the Cable Box sometimes changes the
channel. But, the IR emitter is focused in a small beam, so that unless the
IR keyboard reflects off of something, or the receivers are right next to
each other, there oughtn't be interference.

On the subject of PC Jr's, I've always had a silly question: how do you
use more than one in the same room at the same time? Don't the IR
keyboards interfere with each other? Or is there some obvious solution
to this problem?
I've noticed that some of the Web-TV units also have IR keyboards...
do they have a solution to this problem?

I think that the IR keyboards are the same thing for jrs and for Web-TVs...
a joke. I mean, they belong with video confencing, (responsive) touch
screens, and gigahertz processors. Right now, the technology is too
expensive to get a good use. (IE make something cheap and with few
functions, like a remote, or expenisve and keyboard functions, but at a high
cost). I've seen the Web-TV IR keyboards (a very slim & beautiful-looking
unit), and they cost hundreds of dollars. When you buy the add-on printer,
keyboard, and stuff like that, the price probably soars to a higher price
than a sub-$1000 PC (I've seen 166MMX boxes for under $500), it was the same
problem with the jr: You promise them cheap, easy to use, and seemingly
child-like to use. You end up with bad IR transmiters/recievers, expensive
replacements, a high initial-cost, (the jr. shipped for like 1,200, not the
promised 700 bucks.), and babies are bad enough with remotes. What do they
do with 110 volts, a IR keyboard and reciever, and a cartrige system, all
wonderful devices used by adults/older kids? The results are hard to even
think of. If they could make a computer with less than 20V.... that would
probably be OK....

<Actually, didn't some of the DECmates come with a RX50 floppy drive?
<Were these capable of formatting?
DECmate-II/III are rx50 based.
Actually the RQDX1/2/3 can format a rx50 but the code to do so is not
supplied. The PRO350/380 and DECmate-II/III can't becuase the the floppy
controller that can use handled by an 8751 uP, and the floppy subsystem
does not have enough memory to buffer all the needed data for the 1793
format track command (all bytes including gaps must be supplied).
Some of the DEC controller work alikes may have formatting capability using
RX33 type drives(must have dual speed and nultidata rate).
Any CP/M system with 179x compatable chip can format an RX50 and it's
possible to do it using some PCs (controller/programming dependent).

Been doing a bit of an inventory (sanity check) around the Computer Garage
this weekend, and have come across some units that need to find a new home
to make room for things somewhat less contemporary.
Asking price for any of the units is $25.00 plus shipping, or trade for
other items of interest. (see the Computer Garage 'Wish List' for some
possibilities)
Available Quantity Description
4 Digital DECstation 2100
1 Digital DECstation 3100
1 Digital DECstation 5000/200
These are CPU only, various configurations of memory and hard drive, built
in video and ethernet capability. No OS. (suitable for ULTRIX or
NetBSD/MIPS) Obviously, no shipping if you pick them up! (Beaverton,
Oregon.) No guarantee of condition, though they are in good shape by
visual inspection. Indicated as functional when removed from service by
person who provided the units to me.
Please note: these are MIPS processor based DECstations, *not* VAXstations!
These units will *not* run VMS or any other VAX software.
Drop me a note if interested.

Hi!
I just had one of those wonderful days where I was destined to get a new
computer or four. :) Nothing madly unique, I think, but they filled most
of a hole in my collection. I followed a lead on a possible Apple or 2, and
ended up making a deal where I swapped my extra four IIc's (a job lot with
a pile of manuals - I wanted the manuals but already had the computer) for:
Apple IIe enhanced
Apple IIe Platinum
Apple ///+
Apple IIgs Woz Edition
and an LCD screen (Apple) for the IIc. My questions are simple - I know
about the IIe's, which are common, but what about the LCD screen and the
///+? I had seen neither before in Australia, but this doesn't prove much.
Are they moderatly common, uncommon or heaps rare? Although it is good to
know why the LCD screen didn't sell - it works great, but you do have to be
at a perfect angle, the screen is a very odd angle, and, although legible,
it is still quite faint. Oh, and anyone know where I can get some Apple ///
software? It came with some, but no Basic or games stuff.
Best thing about today was the new contact - he gets in a lot of old
apples, and will be happy to pass them on to me because he says that I am
genuine, not someone trying to make money by taking them off him for
resale. :) This is a good thing - before long I may finally have the entire
non-Macintosh Apple line.
Finally, someone was asking me about the Amstrad Notepads and their
availability on Australia, A couple just came up for sale for half the
normal second-hand price (still quite high, but they are still oddly
popular) along with 2 Laser PC3s, a Laser PC2 an old Casio and an old NEC
notepad/laptop thingy. I will pickup some for myslef, but I could pick up
teh Amstrad if he wants one. :)
Thanks heaps,
Adam.
Well today wasn't the best as far as hunting goes. One of my main finds
was an Atari 130XE, the case is like my 520ST, but I'm possitive this is an
8-bit Atari. What is the story with this one, and can it use the same
powersupply as my 520ST? If it can use it I think I'll finally have enough
pieces to get an 8-bit Atari up and running.
It has a cartridge port that looks like it will take the cartridges that go
in the Atari 800 I've got (it's also missing a power supply).
One major plus is it had the necessary cable to connect the computer to the
floppy drive I picked up a month or so ago. Although the cable seems to be
intended to go to this real cool looking little box, an "Atari 850
Interface Module", which is complete with a power supply, and a operaters
manual. The operators manual has the following note, which I think is
interesting "We have included a photocopy of the Operator's Manual in order
to expedite initial delivery of the product", and it continues with
instructions on how to get the printed manual.
What was probably the biggest find was a Macintosh Colour Classic minus
keyboard and mouse for $5.00, only has 4Mb of memory, but it just might end
up replacing my SE/30 as my Word Processor. I just wish it could handle
32Mb of RAM like the SE/30, instead of a measly 10Mb (OK, I admit, that's
more than I need for what I'm threating).
The other good finds were a VIC-20 in the box, but missing the manuals
(I've got those already). I found a VIC-1541 at another place, I'm hoping
to get it cleaned up and running. Most of the rest was manuals and cables,
along with a box of Amiga software (most originals).
Also picked up a Daystar LT200 card (Still sealed in the anti-static bag)
to connect a PC to LocalTalk, anyone know of any Linux support for this?
I'd love to use my Linux server as a bridge between EtherTalk, and
LocalTalk. Especially since I've got LocalTalk Software for my Amiga's,
and the IIgs's will also do it.

New day, new aggrivations...
I've been trying to get an ST-212 drive formatted up as an RD51 so I can
install a copy of Micro-RSTS onto one of my systems.
Got the parameters to format the drive on my VS2000, and that seemed to go OK.
Put the drive into the system (a MicroPDP 11/23), and it looked OK until I
told the RSTS installer to prepare the drive, at which point it started
complaining about various things, and claimed that the drive was an RD52?!?
Back to the notes... Find a note that drives formatted on a VS2000 are not
compatable with an RQDX1 controller... Whats in the 11/23? Yank the back
off... Figures... An RQDX1! FOO!!
Off to the board box... Locate an RQDX3, looks promising... Install it in
the system... Now the system completes its self test and immediately
complains about a "DU0 - ERR 15 Controller Error". WTH is this? Off to
the book shelf... NUTZ! Latest book I've got only gets up to the RQDX1!
Decide to bag it for the night... Put the RQDX1 back in... Same error???
AARGH!!!
So to the questions:
What is "DU0 - ERR 15 Controller Error" ?
Did the RQDX1 perhaps munge the format on the drive during the install
attempt?
Anyone have a list of the jumpers on the RQDX3 that might be of use ?
Can a RQDX3 be subbed straight across for an RQDX1 ?
If not, does anyone have a formatter disk (or whatever) for the RQDX1 ?
Why am I now getting the same error from the RQDX1 and the RQDX3 ?
Anyone got a spare copy of a manual that covers the various RQDX? ?
Foo!

I need your advice. I started subscribing to computer magazines around

others back before Compute!, and served a while on the InfoWorld review
board, doing Commodore stuff. Wrote for many of the short-lived computer

circa 1979-1988 computer literature. Saved everything. Have two C64

So far, you are the only person I have found who might know where I can
unload these goodies. I don't want to put them on the dump but Boss Lady
is getting a bit pissy about it.
Is there a place where I can advertise on the net? The stuff is in

Today I adopted a 256k Apple ///. It has a single internal floppy drive and
two add-in boards from Titan Technology. One is labeled "///+//" and the
other is "///+//e". They are joined by a small 6-conductor ribbon cable and
one contains RAM chips. Any idea what these are?
Also, can someone point me to a good /// FAQ. Thanks!

??? I'm not 100% sure I understand your syntax, but I think you're
suggesting that I repair the existing supply. That's a great suggestion,
and I would do it IF I had an adequate schematic diagram. Somehow, I don't
think DEC would be willing to part with such anytime soon.
Unless someone can suggest what component to look at (I think it's the +12
supply that's popping on and off), I will continue to pursue a replacement
for now.

Hi, folks,
I've inherited a DEC VAXServer 3100 with a trio of RZ23 disk drives and a
TZ30 tape drive. Looks like a fun unit to play with, but the power supply's
bad (the LED blinks at about one-second intervals and the thing never boots).
Anyone happen to have a spare PS? Failing that, can I yank the boards out
of a VS3100 power supply and transplant them to the larger housing?
Thanks in advance.

Greetings,
I noticed you answered another person`s questions about their PC jr.
so I wonder if you could help me.
The pins where the monitor plugs in have been broken off.
Do you know of where I could get a new piece? Can I just use the A/V
jacks to plug into my TV? Also where can I get some software or an
IBM basic programming book?
I would greatly appriciate any information you could give.
Thank-You,

Both the LCD screen and Apple ///+ are quite rare. I've seen both sell for
over $100 in auctions. The LCD screen is the rarer of the two. Not sure
where to get software for the ///+. I have an Apple /// as well and not a
single floppy for it. The Woz IIgs is one of my favorites, but its still not
worth much.

Hello all,
One of my recent finds is a Nixdorf 8810 (a PC/XT). It has one hard disk
drive, and it doesn?t start. It?s a Miniscribe Model 3212.
Does anybody know its physical parameters (heads, cylinders, sectors)?
Thank you in advance.

If need one I can get you another PCjr case to use for parts and a the basic
manual that came with the jr for cost plus shipping. Cost for PCjr and book
about $3.

It's a model LT-3200 40 by Paoku P&C LTD. I plug it in and get nothing, no
power brick is used, cord plugs into back of unit. There are no sounds,
lights, or anything when I try to power on the unit.

I forget who (Murray Leinster?) wrote "A Logic Named Joe", which very
closely describes the information explosion of the Internet.
I have just had an IBM 5100 "Portable" computer (circa 1976) donated,
along with a 5103 printer and a 5106 tape drive. No documentation or
software, so could anyone tell me what I have, what operating system it
used, and what kind of tapes?
Thanks

I've never heard of a microcomputer that used EBCDIC, but there are a lot of
things of which I've never heard. It is used in IBM mainframes and minis.
Here at HUD we have a Hitachi mainframe that emulates an IBM, and it uses
EBCDIC internally. We have file transfer utilities that take care of
translating into ASCII as necessary.
What does it stand for? Gee, it's been a long time. Let's see.
According to the "SAS Compantion for the MVS Environment," it stands
for Extended Binary Coded Decimal Interchange Code. That sounds redundant,
but that's IBM for you.

A number of the 8 series aquired desktop status but never by intent
portable. They simply weren't rack bound.
The HP???? struck me as something portable(toteable) as it was a complete
machine that could be moved be moved from one place to another as a unit.
The earliest thing I'd seen that was portable was a home brew 8080 system
with build in keyboard and TV RF output back in '75 and it wasn't a PT SOL.
Though the core of it was S100 boards from an altair.

What I saw demonstrated at the Science Museum (part of the British
Museum) 5 years ago was a working _difference_ engine. This had a
couple of design bugs fixed (one in the ripple carry mechanism IIRC) and
no printer.
I don't recall anything about an analytical engine being built at this
time. Has it been done since? Do tell!

I have the PC-10 here, so I knew about this. :) There was also, from
memory, the Commodore Colt and PC-30. I also seem to think there was a
PC-5, but I can be corrected on this. I imagine there were later models as
well.
What was interesting for me was spotting a Commodore MS-DOS laptop
recently. I thought that the only commodore laptop was the prototype C-64
laptop - I wasn't aware that Commodore made any more, even if it was only a
pc clone. UNfortunatly they were asking too much for me, although I would
have considered it if I could afford the machine.

Has anyone ever built a Braille writer out of a punched tape machine? It
seems to me that slight mods (i.e. embossing, not punching) would be needed.
I have a blind (she doesn't like to be called "visually challenged") friend
who asked me about OCR-to-Braille conversion, and I thought I'd ask you
all...
ps Speaking of political correctness, how do you take _your_ coffee? I like
mine Hispanic (rather than Caucasian or African-American) in color, and
