I'm "just about" finished with an emulator for a Control Data
3300 computer (you might ask "why" - I'll explain later.)
But I'm looking for diagnostics tapes (instruction, floating point,
mass storage, memory, etc.) Also, other operating systems would
be interesting (I was dumb back in the 70's and didn't make copies
of all my old stuff...) such as Master with MATS or MSOS or Realtime
Scope. (I have no problem reading 7 track tapes.)
I'm building this primarily to resurrect an obscure language, also
developed at OSU, called "Oscar". It was a numerical person's
dream interactive system for it's time (way before common graphics
terminals, alas) including all sorts of large precision arith and
rational number management (ratios of integral fractions) which made
matrix manipulations a lot easier. Oscar ran under OS-3 and hence the
need for the emulator. Besides, it's fun. (And I have source for damn
near all of the OS-3 system, languages and tools (I was "with it"
enough to make copies of those at least.) The original 3300 at OSU was
"decommissioned" back in the early 80s, so this part is even "on topic!"
It's a bit depressing (and humiliating) to see that my entirely-C-based
emulator (i.e. NO assembler "optimization" on my part) runs at nearly
the speed of the original machine on a lowly 66 mhz 486. (1.6us/cycle
where instructions USUALLY took 2 cycles, for fetch and memory reference.)
It'll probably scream on a reasonable Pentium-class system. (By inference
will we be writing emulators in 15 to 20 years that emulate 400 mhz Pentiums
and Power PCs at the full speed of day? Boggles the mind...)
I'm emulating most CDC periphs (as far as I can without real "iron") so
the emulator should handle virtual 604/607 tape drives, disk controllers,
501/512 printers, card readers, punches, etc.
I realize this may be a bit "off topic" with respect to the other
"mainstream" collectable computers (dec/hp/etc.) but, hey! it's
what I learned on way back when. And the computer was far too large
to ever think of "owning" one.
For reference, the 3300 was a 3rd generation computer (no IC's - all
Germanium transistors) with memory that came in chunks of 8k words
(24 bits) all the way up to 256k words (LOTS of boxes.) Each 8k
took half a 7 foot tall by 6 foot wide rack (IIRC). I think
very late in life they had 32k modules... 24 bit ones-complement
math with a "reasonable" two-state architecture (program/system
mode) that actually worked (OSU's may have been the only one that
really challenged it, though, running timesharing software on it.)
Any and all software for the beast would be welcome. For reference,
anything for the 3150, 3200, 3300 or 3500 would be welcome, as well
as any CDC docs on these machines. I've got quite a few, but some
of the more obscure controllers (3317 terminal control, for example)
eluded me. Information on 3600 or 3800 (a sort of "48 bit word" 3300
and 3500) would also be welcome, as these two lines shared a lot of
peripherals and controllers.
And of course, assuming anyone else is as silly as me and wants to
play with this mess, I'm happy to make the source/executables available
(it's Linux based.) It's not "ready for prime time" yet, but soon...
Thanks for sharing the bandwidth,

What's that got to do with it? Diodes are analogue parts - the output
(current) is a continuous function of the input (voltage), not a
discrete one (to me the difference between an analogue and a digital
component). In fact, Allison, you were saying only a few days ago that
you don't need any amplification to make an analogue _computer_ (with
which I agree - although some of your examples I wouldn't call
computers).

That is an excellent concept. Thank you - I'll remember that.
For non-electronic digital computers, where do Facit mechanical
calculators lie? I have one (which is driven by an electric motor but
could conceivably use any motor) which has algorithms for optimised
decimal multiplication and non-restoring decimal division. It is not
programmable, but it is pretty complex - and all done mechanically.
For pneumatic computers, I think some pipe organs of the turn of the
century came close - you could program some buttons to set various
combinations of ranks for fast selection during performance. However,
the more complicated schemes of this nature (popular around 1920) used
electrical as well as pneumatic logic elements.

It certainly would. Even the RT-11 driver (which is about the simplest

It's basically a message-passing protocol, unlike most of the earlier DEC
disk stuff where you can poke the hardware registers to "make things
happen". To oversimplify, with MSCP you make a message containing
instructions, put it in a memory buffer somewhere, tell the controller it's
there, and it does the rest with DMA, returning a response message.
The relevant documentation is "MSCP Basic Disk Functions Manual",
AA-L619A-TK, and "Storage System Diagnostics And Utility Protocol",
AA-L620A-TK, which in turn are parts of the UDA50 Programmer's
Documentation Kit (QP-905-GZ). My copy is version 1.2, April 1982.
It's not good bedtime reading; the plot's a bit too convoluted and the

If your developing with RT-11 for a specific task then sysgening is
needed. If you need to run BASIC, DECUS-C, MicroPower Pascal, write
assembly code files or edit text then the stock monitor are just fine.
Sysgening to simply move to a different varient of PDP-11 cpu or disk
however is not required. The typical example of sysgening RT-11 I've
done was to use a console that wasn't DL (standard PDP-11 serial line
unit) compatable.
RT-11 was designed as both a development enviornment and a realtime
executive for embedded applications. It's pretty flexible and small
so it's good for lots of other stuff. It weakness (there is one) is
that it does not use a scatter-gather map for storage so storage space
can be poorly used due to device fragmentation.

I have just returned after a long weekend to find my mail had got set to
Postpone again. This has probably all been said but I thought I'd put
my bit in anyway.

Allison

A filter made of passive components or otherwise I wouldn't consider a
computer, although I agree it is definitely analogue (Americans may omit
the ue where appropriate).
I would say that an analogue computer:
(a) combines two or more signals
(b) does so in a more complex way than by simple addition or
subtraction. (But this could be A+dB/dt, for example)
An analogue computer need not be electrical at all - quite complex
analogue functions can be implemented in cams, for example. A good
example of a simple embedded analogue computer is the ignition
distributor on a petrol engine. This:
Takes two inputs - camshaft angle and manifold vacuum;
Differentiates camshaft angle to get engine speed (centrifugal
weights on springs);
Applies some non linear function to engine speed (cams attached to
the centrifugal weights);
Adds together camshaft angle, function(engine speed) and constant *
vacuum level;
Compares the result with a reference angle to generate pulses of a
given width for the ignition.
I claim that is a simple (but actually quite sophisticated) analogue
computer.

Agreed 100% (As Tony would say). An excellent example of an embedded
analogue computer.
Another example is the convergence circuit in a colo(u)r television.
This takes the two timebases as inputs, multiplies them and their
squares/ first derivatives etc. by user settable constants, and feeds
this back onto the deflection systems of the tube.

Agreed it could be part of an analogue computer. But I think Tony's
point was that it does not by itself make one. Otherwise practically
any analogue circuit becomes a computer (One of Vonada's axioms, I
think: All circuits are amplifiers)

Definitely analogue systems. But some are merely filters, not
computers. (I think a PLL almost qualifies as a computer, though...)
But in general, I agree with you both - analogue computers are often
small, simple and embedded, and they're a heck of a lot more common than
most people think.

I know, I know, when I get a chance. For now;
I found an Anderson-Jacobson 1200 BPS modem (AJ1256). Is there any
thing special about it, or is it safe to throw this back?
This was on the way to a thrift store. There I saw:

RCA Victor, couldn't tell if it worked, $75, no I won't buy it
IBM PPS II ( I think) form printer - does anyone have any experience
w/ this?
I didn't buy any of the three, but I might get the TI-60.

Here's an interesting artifact. I got the reference manual for Microsoft
BASIC-80 (version 5) over the weekend and it still had inside the original
non-disclosure registration card that I guess one was compelled to sign
and send in before they could use MS BASIC. This book was distributed
with some morrow system as the card is addressed to Morrow Designs
Software License Department. It reads:
"The party below agrees that it is receiving a copy of MICROSOFT DISK
BASIC or FORTRAN for use on a single computer only, as designated on this
registration form. The pary agrees that all copies of MICROSOFT DISK
BASIC and FORTRAN are owned by MICROSOFT, that all copies will be strictly
safeguarded against disclosure to or use by persons not authorized by
MICROSOFT to use MICROSOFT DISK BASIC or FORTRAN, and that the location of
all copies will be reported to MICROSOFT at MICROSOFT's request. The
party may make up to two additional copies only, for back-up purposes.
The party agrees that unauthorized copying or disclosure will cause great
damage to MICROSOFT."

I promised Sam I'd look this up a long time ago. I had some trouble with
the phone lines, though, which made it impossible to use the modem.
But here it is. I seem to have a preliminary version of the 'Voice Module'
manual, although I did not get the module itself with the machine.
The manual goes into a lot of detail: theory of operation, external
interfaces, architecture... schematics...
I'll quote from the overview:
INTRODUCTION TO THE MODULE
__________________________
GENERAL
The Voice Processor Module, shown in Figure 1-1, provides a fully
integrated voice and data interface between a workstation and the switched
telephone netowrk or commonly used private automatic branche exchange
(PABX) system (supporting Tip and Ring connection). When used with a
digital PABX system, all signals and transmission between the Voice
Processor Module and the PABX occur via analog techniques.
The Voice Processor Module is an X-Bus module containing two
printed-circuit boards. The first board contains a Bell 212A-compatible
modem.
The second board contains the following:
* modular jacks for two telephone line interfaces (FCC, part 68, registered)
* additional modular jack (FCC, part 68, registered) that allows
connection to any standard voice unit (telephone set)
* analog crosspoint switch allowing any device to connect to either line
under software control
* Dual-Tone Multifrequency (DTMF) touch-tone auto-dialer
* DTMF touch-tone decoder that permits numeric data entry via remote
voice unit touch pad
* call progress tone detector
* voice amplifier
* Adaptive Pulse Code Modulation (ADPCM) CODEC (Coder/Decoder) for
support of digitized voice communications at speeds far less than the
normal 64Kbps
* 8051 microprocessor to control all module activities
(...excepts from following specifications...)
Modem board is originate/answer, full-duplex. Supports 212A and Bell
103/113.
DTMF generator generates all 16 DTMF digits, may be programmed to transmit
various key sequences, and can generate single tones.
CODEC and ADPCM technique allows recording/playback of digitized voice
information at 6-kHz (24Kbps) or 8-kHz (32Kbps) rates.
Software support is provided by CT-MAIL, CT-Net, and "Operator" software,
which is specifically tailored for the Voice Module as follows:
* Telephone directory management, which has the ability to add, delete,
modify, and look up entries in a disk-based telephone directory, and
automatically establish calls using the information in the directory.
Menus provide assistance in accessing special functions used by PABXs.
* Voice digitization, which allows the operator to use the CODEC to
record and play back calls or messages. This capability enhances
CT-MAIL, where it is used for voice annotation of written documents, as
well as the inclusion of voice attatchments to textual mail.
* Telephone answering, which allows an unattended system to automatically
answer the telephone and perform a variety of user-selectable
operations ranging from simple messatge playback/recording to input of
numeric data from a telephone touch-tone pad.
There you have it. All typos are my responsibility.

I recently bought a Maxtor IDE along with other HDDs at a hamfest. When I
got it home, I noticed that it "clunked". No response when I hooked it up,
so, I took it apart...
The head had gouged its way through the entire thickness of the platter; the
remaining part of the platter was lying loose around the hub! It must have
made a horrible screeching sound for days (months?), but I guess no-one
noticed.
The head is ground away, of course, but the arm's still intact.
Anyone ever seen a worse failure?

As it turns out, I've picked up a couple of other projects and will
probably never get 'around to it'.
I'll give the system away to anyone who can pick it up- I'm near Boulder,
CO.
The system is a DecStation 3100 with a VR299 monitor and Dec Keyboard. I
don't have a mouse, or hard drives. I believe that there is 16Mb of Ram
installed. As far as I know, it works fine. (I never got further than
realizing that the mouse was generating an error on boot, and never made a
loopback connector to go further.)
Anyone that's interested, reply via email...
Regards,
Jim Velasquez

============================================
Now the RA is hardware visible. As opposed to the RA81, where you CAN'T
plug it straight into the controller, the RA92 likes that. Go figure.
Anyway, I boot up and say HARDWR LIST.
It sees 2 devices off the UDA50, the RA81 and the RA92. It identifies the
RA92 as a RA92 also.
Now, I try to DSKINT the 92. I get to where it asks me for
pack clustersize. The default here is 32. When I type 32, it says
?Illegal clustersize specified
and prompts me again. Nothing works.
Apparently 32 is too big a number, but it's the required number, so
I've shot myself in the foot.
Is this a known bug? Have I screwed up here? Is there something I can change
in RAM to let me go ahead?
I can't find any mention of this anywhere....

I posted on a trash find about 2 weeks ago on virtually the same machine,
with no response. Ditto on some newsgroups. That in itself is fascinating.The
one I have is a PC-S3-2. The only info I was able to find on Wang's venture
into the world of MS-DOS was on the Wang users bbs and this was pretty slim.
They call it a "classic" Wang, (Apple anyone ?) I was able to get a start-up
file from them but it seems to be an orphan like the Atari PC. There's quite a
few Wang CP/M enthusiasts sites but like the TRS m.2 little info on this beast.
even tho, like the TRS m.2, many were sold to the business community.
Most likely quietly fed to dumpsters around the world since most small
businesses don't have garage sales. You were fortunate ( mind you didn't find
it in the garbage) to have some means of IO. Mine had the 2 winchesters
removed and nothing else. I find the MB interesting with its mix of Zilog,
Motorola and Intel chips. Old Wang was known for it's interesting innovations
and IIRC many of it's people went on to illustrious careers with other
companies , like the original DEC, Xerox, and Atari crews did. I don\t have the
URL for the WUG handy but it should be readily available thru a search. They're
a Brit group IIRC and I wasn't about to pay $35 for the privelage of joining
their discussions. Could you give me some info on the FDD's , KB , etc.

I dragged the RA92 up here, plugged it in as DU1, and started RSTS,
but RSTS says DU1 doesn't exist.
This is RSTS/E v8.0-07.
Is there some trick to do to make the RA92 work, or am I up a creek?
I'll play with it to make sure it's not my cabling, but I have it the same way as the RA81, so I doubt it...

No, but the load bang I described was from a 3.5" winnie.

Not much, it just goes rather faster than normal. I've seen it happen when
a servo circuit failed (actually, a field servoid had removed a vital
component from a drive that he thought wouldn't be used again).

Easy way to find out is to try it :-)
There's a small amount of data on TEAC's web site,
http://www.teac.com/dsp/fd/fd_55.html
but that's really for the -R series which are newer. I've got jumper and
setting info for the GFR (similar to RX33) and a little info on the FD55-FB
and FD55-BVU (40 trk DS) and FD55-GFV-17 (HD 80 trk).
TEAC also have a faxback service, and there's a catalogue of the faxback
documents at
http://www.teac.com/dsp/catalog.html
You could try http://www.psyber.com/~tcj as well.

Head draging...? only if it's crashed even then the motors on those old
drives were huge.
<Can any of these stories happen to a modern drive?
Less likely as smaller platters, less mass and more exotic speed control
servos. The big difference is that you would need som really amazing RPM
to make a 3.5" plater fracture and fail where a 14" platter has a far
higher speed at the perimeter at a lower RPM. Without running the numbers
a 14" platter goes transsonic at the perimeter at something like 14,000
RPM however before you get to that speed the forces working on the metal
are high enough that it will exceed the tensile strength. Also small
imbalances show up with increasing rotational speed and the platter start
to develop vibratory waves which if allow to go to destructive extremes
make for good stories.
I know as I have an operating Morrow (thinkertoys) DISCUS with a 10mb
memorex(m101) 8" drive.

I have a couple of 14" Fujitsus (a massive 135MB apiece) similar to that.
They're the predecessors to the Eagles, which have heavy cast metal HDA
enclosures. Much more fun to watch (and listen to).

Yes, you read correctly. One of the local thrift stores turned up a Xerox
'MemoryWriter 630' for all of $8.00. Since I was in the market for
something to fill out forms with, and curious about the MW series in any
case, I picked it up (with a grunt -- these are not light!).
It's built very robustly inside, and appears to be based heavily on the
8085 chip. The design and layout resemble (no surprise) the Diablo 630
series daisywheel terminals. A good vacuuming and a little oiling later and
it works just great. Original manufacture date is around 1984 (based on the
date codes I found on the components).
No CRT on this one, though I understand that was one option. If anyone
happens to have a user's guide, accessories, options, or diskettes for this
beast, please let me know.

Not seen, but heard...
Some time ago, I had a little Seagate 50MB drive on running on the shelf
above a workstation. I knew it had a stiction problem, so I tended to
leave it running most of the time. So there I was, minding my own
business, as they say, and suddenly there was a very loud BANG. I couldn't
see anything amiss, but I shut things down anyway. Then I realised any
damage that was going to be done by whatever went bang had presumably
already happened. I wasn't going to find much out by staring at a blank
screen, so I powered everything up again. All came to life, but the
Seagate just reported disk errors. Tried reformatting; no joy. So I took
it apart. Every platter had huge circular gouges, and two of the heads
were in bits, mostly embedded in the walls of the disk chamber.

They also have an ftp site (ftp.seagate.com, I think) which has all the
jumper info in text files. They also have zip files giving the info for
griups of drives, eg all the scsi drives, all mfm, etc. I use them so
often that I always have a reasonably up-to-date version on my server.
BTW, I find seagate's site and similar sites much more useful than TheRef.

www.haggle.com. The 3/50 is a 12meg flat-top, and the 1+ has 36megs and a
205meg HD. I started them at something like $5 so they'll probably go for
just enough to cover packaging tape.
The impetus? The space is now being hogged by the System 36 I just dragged
in here....
By the way, does anyone want that Sperry IT I got awhile back? It is
sitting in the garage looking forlorn. It has that nifty Genoa video card,
a memory board, an ethernet card, an unknown size HD, keyboard, optical
mouse and pad, complete manual set (system installation guide, Basic
user's guide, and MS-DOS user's guide), and original disk set. I haven't
had the chance to even power it on yet, so I don't know the operational
status (worked when removed). It's heavy (duh), so if someone just wanted
the cards/HD/etc, I could disassemble and ship what you wanted and leave
the carcass at the local thrift.
Oh yeah, I am in the L.A. vicinity, so if someone wanted to pick it up....

<A question occurred to me today : Can you have an embedded analogue
<computer, and if so, how many op-amps are needed to have one?
Yes, and that's very common. None, a low pass filter(RC) performs a
function and can be considered analogue.
<I was looking at the service manual for my Micropolis 1203 hard disk, and
<I read the circuit description of the servo electronics. It's a fairly
<complicated array of op-amps, which combine integral and differential
<forms of the position error, positioner current, etc. I would claim that
<is an embedded analogue computer.
Valid claim, also a good example of a fairly complex function.
<On the other hand, I think it would be stretching the definition to call
<a simple op-amp wired as a voltage follower an analogue computer.
Correct. However often the buffer is between some function or follows one
so it's part of the analog system.
Other analog systems common to computers:
cassette IO (low pass filter on output) and complex filter/differentiator
edge/peak detectors for input. Some of the acients used PLLs for clock
recovery (KANSAS City is one).
Analog to digital conversion (quantification).
Digtial to analog conversion (filtering)
Disk/tape systems have several layers of analog function for data and
control.

Ok Compaq laptop owners (you know who you are). I have a near new unit
to sell or trade as follows:
Compaq 2815 Desktop Expansion Base. Looks a lot like the Prolinea
line of desktops with a special lid to slide
your laptop machine into a "bay". It has no drives (blanking
plates) but has an internal contrller for floppy or hard
disk and the empty bays. Has a token ring card now in one of the
two ISA slots. Includes ports for VGA, LPT,
COM, KB and mouse. Has an A/B switch on the rear that I really have
no idea of it's use.
This is like brand new but has no manuals.
Looking for $100 cash or will consider trades of items such as
memory, cdroms, sound cards (especially MCA
PS/2 types), etc or a complete Snappy 3/3 Deluxe setup. I will also
consider equal value electronics test
equipment in trade especially function generators, signal
generators, frequency counters, Fluke DMMs, etc.
Email me direct please.

Anybody know of a URL or printed reference to a photo of an Ampere, MINDSET
or eMate machine? Heard of them and I would like to see what they're like.
I have somewhere in my archives old Popular Electronics and Byte mags which
I'm sure show the others on Doug's list. Those NeXT machines were indeed
pleasing to look at. I wish I could find one nearby here to see up close
or/and purchase.

Yep, those are cool. Also, I also kind of like the Toshiba's, the ones with
those cool monitor/TV/speakers, and the box is awsome, too. And that new
Toshiba model... the one in PC Week... the one that has that "30 second
motherboard change", is finally a smart design, if not artistically
pleasing.

Well, the speakers are probably 6". We are playing instrumental

ive been in communication with a lady that has an old kaypro with a lot of
text files on disk she wants to transfer to an IBM for further editing and
safekeeping. i presume i need to cable their serial ports up and transfer that
way, but exactly how? i need some sort of program to send the files on the
kaypro i guess, but have nothing to do it with. if i can do this file
transfer, i'll get two working kaypros, a TI word processor from 1985 and some
NLQ dot matrix printer shipped to me free.

Hi All -
Just joined the list - looks like a great resource for information. I've
been collecting vintage micros for a couple of years now and only recently
discovered there were other fools with the same bad habit. Currently I've
got about 50 assorted Commodores, half-dozen Apple ]['s, two Kaypros, an
Osborne Executive, a TRS-80, a couple of TI-99's, a bunch of Atari, Coleco
and other game machines, and the rest of the garage is filled with boxes of
tape drives, modems, printers and other peripheral stuff. I'm always
interested in trading, so if there's something you need, let me know.
I'll go back to lurking now.
R.
BTW - I've been compiling a chronological list of every computer ever made
for a book that I'm working on - big stuff as well as micros. It's a pretty
big file, but I'll post it (as a MS Word attachment?) if anyone is
interested.

Well, the KS-10 deal went over like a lead baloon...
It seems the HARDWARE to the system has already been packed off to Caterpillar
Spares. But the SYSTEM (disk) is still there. THAT is what they were melting
down. Not the whole rack, just the RP06 packs that had their data.
When I was told the SYSTEM was intact and may be rescueable, we assumed the
HARDWARE. When I asked about config, he assumed I meant "What's the monitor
built for?"
And they don't wanna give me those disks anyway. Basically, I went in and made
a fool of myself... Oh well. Live and learn...

Ummm. Given the number of hybrids around (as we have seen from more
recent posts), your system might be better. But AFAIK in the taxonomy
used by biologists etc. the list of available classes is different for
each phylum, the list of available orders different for each class, etc.
But I have a computer that is hybrid analogue/digital (an EAI-1000, I
think it's called, which is an analogue computer with a microprocessor
doing an embedded control type job to run the system)...

OK... by some act of God, when I try to plug in the HDD alone, it spins up,
along with the PSU. Now, when I take EVERYTHING out, that includes drives,
cards, etc. and just give the motherboard power, it doesn't spin up at all.
Yes, the black pins are in the middle, I know I've got a good connection...
could this be the "No power" line thingy? Should a real-XT case work with a
clone-XT motherboard?

This is not true, many VCRs have version of the NEC ucom75 chips, cmos
single chip microprocessor(512b-2kb rom, 128nybbles of ram(max) lots of
IO for various purposes). The TI1000 series were used in games and
Microwave ovens. Most of the things like lawn spriklers controllers are
chips like 8048/9, PIC, or other cheap in volume mask rom
single chips micros.
The list can go on but true ASICs are expensive to develope and limited
in scope. There are an abundance of small very low cost single chip
micros that can do tasks like those described.
FYI what does seperate most of these from the general taxonomic classes
is that the "program" is inaccessable on most of these so altering it
is unlikely to impossible.

You are leaving out whole categories of computers. Where do VCR and

analyzers? What about lawn sprinkler timers, aren't they

Funny you should mention the Macquarium. Yesterday on my way home I
stopped at a used computer store and found a Mac Plus Macquarium with
the original documentation dated 1992 (a mere $60.00 for a butchered
Mac... I wouldn't buy one because I don't think it's cute and don't
want to encourage this practice). The top of the case had been quite
roughly gouged out, a glass tank fitted inside the case. I'd seen this
on the web before but thought it was a joke.....

Hmm, must be too early... I suddenly remembered a situation like this I
had with a motherboard a few years back...
check the ISA slots; make sure nobody's stuck a card in there and
mangled a few of the pins. This board I was given had the same trouble,
and a couple of the pins were shorting out and the system was shutting
it down. Nice three-second fix once I'd found the problem!! :)
good luck,

Then again I'm not in charge of this list either.

:-) I doubt it...
The real crime is those who buy sewing machines with pedestals and
treadles, throw away the sewing machine and turn the pedestal into an
olde worlde iron framed coffee table. I am told by a friend in the
trade that this is v. common.

There was a system/36 that was the size of a desk pedestal but I never
saw that particular variant. The system/32 (and possibly the s/38?) had
a desk built into _it_...

In the early S-100 days (1975) the engineering lab I worked in got an
early Altair (we needed small cheap computers to embed in environmental
monitoring instruments). A few months later we got one of the first
IMSAIs. After about 3 minutes of comparing the two, we voted to use
IMSAIs and the Altair was relegated to being the doorstop for the lab
doors. I assume it wound up in a surplus action some number of years
after I left. BTW, the embedded controller we actually used in the
instruments was a single board Intel 8080, their evaluation kit board,
the precursor to Multibus. We used the IMSAIs to develop and test the
code in the lab.
Jack Peacock
Well, I recall from The Secret Guide To Computers that early
Timex Sinclairs were used as doorstops at Timex (or whatever).
Some sick minded person might gut a NeXT cube and use it as a
little stool for flowers at an exhibit of abstract art ;)

I'm selling a Mac 128 on eBay. The bid is up to about $60 and the
auction ends today. If anyone is interested in it just go to the link
below and bid through the auction. You will have to pay shipping so keep
that in mind.
11941337: Original Macintosh! 128K / KB / FD / More!
Current bid: $51.00
Auction ends on: 04/30/98 18:31:45 PDT
http://cgi.ebay.com/aw-cgi/eBayISAPI.dll?ViewItem&item=11941337
I also have another 128 that seems to work but has a dead screen. And a
pile of the external floppy drives (3 I think). Includes keyboard and
mouse. Accepting offers.
I've never seen an 80W power supply. All original IBM 5150 PC's I
worked on had a 63W power supply and the IBM XT's all had a 130W power
supply. You mentioned your supply has a 220V selection? If so and you
are stateside, make certain it is in the 110V position. If you have a
220V power supply that doesn't have a 110V selection and you're
stateside... you're out of luck. I concur with all those previous
respondents that this supply of yours is most likely good but loaded
down either by excessive loading (more cards/memory/drives than the
P/S can service) or a short circuit in one of the add-on boards or
drives. Just unload until you find the cause.

That's odd. My power supply's 130W. It's also the 220v variety, as that's
what's available here. It was made in Dublin, Ireland. It really looks
like it was how it was made, as it looks REALLY built-in to the case.
Anyway, I can't see any reason that it would be dememanding too much power,
all I have connected is a XT clone motherboard, (however, it WAS sitting in
an XT case) and a XT floppy drive connected. So, any ideas? I think that

Yep, Apple Records. Actually, it was founded by Paul Macarthney (however
you spell it) and John Lenon, the Beatles. Their idea was to have people
coming in, and doing what they wanted, getting profits for their records,
and not having to go beg the brass at some corporation. They lost more and
more money, into the 80's, when they were "eaten up" by Capitol records.
The Beatles CD's available now from capitol still feature the Apple logo
(not Apple Computer), and the CD's also have it.

hmm, I've overloaded a standard XT (80W) supply before trying to run a
couple of the original 10MB hard drives (amongst other things!). Guess
it depends on what cards and stuff you're running (some of those old
full-length boards drew a hell of a lot of power...)
I've got an old pre-XT machine somewhere with the 63W supply, I seem to
remember it wouldn't even power one 10MB drive with motherboard and a
single floppy drive in place... I can't remember why on earth I even
tried it though, I don't think the pre-XT machines (what was their
proper title btw?) would even run a hard drive...

Sorry, Sam, what I meant was our systems here are badly set up. And I
refuse to spend hours trying to get WNT to do things properly when it's
probably not capable of it. When I try to use your forms page, Internut
Exploder asks for a directory in which to store outgoing e-mails and
then won't accept any that I give it. (For the record, I am _not_ a

I will get TCP/IP on one of my UNIX boxen at home and get a personal

Physical address will follow by private e-mail.

It sounds like a GridCase3. Probably worth $45 easy. That AC module is
definitely worth something. If I hadn't just bought a TRS-80 m600 and a

I finally had enough time today to go to Canadian Tire and pick up a set
of allen wrenches, so I finally pulled the disk drives out of my ailing
Kaypro 2.
I moved the resistor pack to what was formerly drive A, and swapped the
jumper blocks, put everything back together... and it worked! The Kaypro
2 booted up WordStar with absolutely no problems.
Now drive B (formerly drive A) can't be accessed. It gets a "Bdos Err On
B: Bad Sector" on known good disks. So it's definitely the drive that's
bad.
Mechanically the drive seems sound, so I guess I have to assume that
there's something wrong with the electronics. I haven't done a
side-by-side comparison with a working Tandon drive to see if there's any
obvious differences, though.

heres a quick and dirty way to test one:
if you have a hard drive, plug that into one of the power connectors, then hit
the switch. that will let you know if its working or not. this test will work,
as i use an xt supply just to run a scsi drive for my mac when i bring it out
for testing once in a while. if not working, i have several extra xt supplies

The symptoms you describe could also mean that your disk drive is

It is some years since I looked at the Cray 1 in the Deutches Museum in
Muenchen (Munich), but I distinctly recall seeing lots of 10xxx chips in
it. I remember I had just been given a board from the CPU of a Cyber
two-hunderd-and-something (?) that had been thrown out by Muenchen
Technical University a few months earlier, and this board has lots of
100xxx chips on it.
Philip.
I posted this a few weeks back, but noone answered, so I'll ask it
again.
There is a certain Macintosh 5400/180 at my school whose hard drive
crashed about a month and a half ago. When it tried to start, it
wouldn't really seek, just made a ticking noise and the LED would
flash. So, we took it out, ordered another one. A few days later,
it died the same death. So now we have another one. My ethics don't
allow me to just put in a hard drive knowing it will be destroyed.
What should I do? One hint is that the Macintosh is in a soundproof
booth, and is powered from the booth, which is plugged in. But, the
mac is plugged in via a "surge protector".
Ideas? Could it be bad power? Any way to check?

as long as its an xt power supply and not one from a 5150 pc, there should be

Could you simply be overloading it? Seem to remember original IBM XT
supplies do this when there's too much load on the system - does the
supply seem to work without anything connected to it? The fan should at
least spin then...
It's equally likely that one of the cards you've got, or the motherboard
itself is faulty in some way and is causing the supply to shut down. If
you've got a voltmeter try checking the output voltages.
Final possibility: did XT supplies have a "power good" reference line
that the motherboard tied to +12V to signal that everything was Ok?
Can't remember if this was only AT systems that provided this. If they
did it may be that your new board doesn't provide it but the power
supply expects it to (wait for someone else's words of wisdom I guess,
been a while since I've fiddled with these things - if that is the cause
though you should be able to simply tie the line to +12V and then
everything should work... :)

Sounds fun!
It occurs to me that I gave a small talk on the Tek 4050 series last
autumn (fall). I'd like to come to the VCF, and I could probably bring
my 4052 and some demo programs, and give an adapted version of the talk
(either in a scheduled slot or probably more suitably on a demo stand
with the machine).
Finally, Sam, could you put me on the VCF mailing list, please. I tried
to subscribe from the web page but we've just migrated to Lusedoze Not
Tolerable and Internut Exploder, with the result that I couldn't get it
to work...

I can't remember who mentioned they had a 1611A without probes, but I
checked it out in the lab today.
The pod with the ZIF socket and Z80 clip does have a little "stuff" in it,
but the "ordinary" microprobes are simply buffered by a little box
containing a pair of 8T37 buffers and a few decoupling capacitors. This
box is connected by a plain ribbon cable to a connector on the 1611A. If
you need to know the connections/layout, I'm sure it would be easy to
reverse-engineer.

I found a mention via a search engine of three Teraks that were

Sure it was. The Franklins were probably the best known Apple rip-offs
^H^H^H^H^H^H^H^H er ah, clones. At least until Apple sued them and
Franklin had to actually design their own machines.
>So the Soviets pirated the Apple ][, who didn't?
But you missed the point. No other >COUNTRY< tried to pass off a pirated
machine as their own. In fact, most cloners (pirates?) bragged about their
similarity to the original machine, the Soviets claimed that their machine
was an original design. To top it all off, they didn't even have the good
sense to change the copywrite notice!

that machine was impossible to air cool and remain that small. Why
small? Conductors propagate singnals at 1nS a foot and a cable of several
feet actually represented a significant delay to the overall sheme of
things inside.
A note: The other commonly known and slightly more recent ECL machine
was the DEC VAX9000, built using ECL-100k built on custom air cooled
hybrids. It also consumed power in great quantities and had special
cooling considerations.

AFAIR the ordinary probes are just micro-hooks on single wires, which plug
into a little distribution box on the end of a ribbon cable.
It's quite a nice analyser, so "play with it" gets my vote. It was also
quite popular, so I expect you could find manuals if you look/ask around.
I'm sure we have some 1611s or 1610s in the labs. If you want me to take
a look at them next week, shout. There's also a description of both
models, and several examples of use, in John Lenk's book "How To
Troubleshoot And Repair Microcomputers" -- which IMHO isn't a very good
book, but there seem to be lots of old copies of it about, and in

[Stopping thinnet with a 3270 card...]
I once heard of a manager of some sort plugging thinnet into the back
of a VT220 (?It was VTsomething...?) video-out port. Seems he thought
it was one of those network computer deals...
VT220s had a video out BNC connector. You could drive a monitor with
it, but wasn't very useful plugged into a coax Ethernet cable.

Yes, happend at DEC sometimes. DEC had VAXmate (AT class) machine that
was netbootable and could do file sharing via eithernet. There were also
X-terminals (DECmindows) that used the net for both the hookup and loading
operating software.

<Excuse my ignorance, what does ECL stand for?
ECL or emitter coupled logic is a form is bipolar logic that operates
at low levels and is non saturating. Non saturating is where the active
devices are neither fully off or fully on. Logic levels are referenced
to a bias level so translation to MOS/CMOS/TTL is required. The reason
for doing non-saturated logic is speed, transistors have a problem like
tubes of charge storage making them harder to turn on or off and reducing
speed. Generally speaking from the late '60s through the '80s ECL managed
to be a factor of 5-20 times faster than the prevailing logic system(RTL,
DTL, TTL) until sub-micron CMOS started to get under 10ns. The last ECL
parts I looked at(years ago) were sub 1nS and could be clocked faster than
1000mhz. An example of the speed difference is 1974 the fastest TTL
divide by 10 (7490) was maybe 35mhz, ECL divide by 10 was 500mhz.

Yes, for certain sorts of useful. You plug the BNC T onto the back of
the card, and it stops all communication on that thin-net segment. At
least that's my experience with such devices. (They told me it was an
Ethernet card. I didn't believe them but they insisted, so I shrugged
and plugged the cable in. It took about five minutes for the
folks hollering from the other lab room to find me.)
If you want an MCA Ethernet card, look for one with both a BNC
connector and a 15-pin D (AUI) connector. Maybe an RJ45 too but
I don't recall seeing many MCA cards that had all three connectors.

I had never seen that Toshiba chip before. The 2716 was just a guess

chip?
The Toshiba part was a regular 2016/6116 2KBx8 static RAM. Same pinout
as the 2716 except for the additional WR* line. IIRC there were LP (low
power CMOS) versions too, various speed grades.
SDS (S.D. Sales) made an S-100 similar to the Teletek, except it could

That's possible, but the probes themselves definitely are just wires with

I think yes, you are the only person with a 5103 printer. I have a 5100
but no printer. Didn't know until your message that they even made one!
So I guess I don't need the ribbons...yet...
However--
I am interested in this --
(1) Computer Wharehouse Store catalog, Spring-Summer 1977. SWTPC! Imsai!
Kim-1! $1200 floppy drives! A slice from the "good old days" of the micro.
The pages are a bit yellow, but in good shape. The cover is also nice, but
the previous owner scribbled his name on the top.
-- if it's still available.

Well thanks for letting me put the things I had up here on the list.
I've sold or traded both the Kontron logic analyzer pair and the Tek
7612D digitizer.
I still have a single channel 10mhz RCA solid state scope in great
(looks new, works new) shape with manual. It's a model WO-535A and is
>from approx 1975 time period. I need $100 for this to fund a few odd
projects such as buying a Snappy 3 video capture.
Please contact me by direct email.

I have a book that hasn't even been used here that may be of interest to
those of you into vitual programming on a PC.
The title is "Playing God - Creating Virtual Worlds With REND386" by the
Bernie Rohl and published by the Waite Group. Includes a still-sealed
3.5" disk fullof source code for C++ and other neat looking things. Made
to run on a 386SX to a Pentium machine with VGA, 4mb RAM and a hard
disk. It says it's an intermediate level book.
The cover price on this glossy softcover with disk is $29.95. Anyone
interested in it? You can have it for $15 which includes mailing within
the continental 48 states.

Now this is interesting---Perseus Development Corporation developed a new
version of their SurveySolutions for the TRS-80 Model I. 4K required, but
as always, more is better.
The date of the release is suspicious (April 1, 1998) but still, it is
interesting and the source code is available. The web page is at

OK... here's the current scoop. Sam Ismail has claimed the DEC networking
book and the Microsystems handbook. I still have available the DHV11
technical manual, the Everex manual, and the DEC programming card.
The remainder of the hardware is on hold pending a possible taker. Thanks

"Our science can only describe an object, event, or living thing in our own

It seems to be all in the very preliminary stages, but time is running
out...
Does anyone on the list have space for a large (two-rack) Multiflow Trace
machine? One has popped up, and it seems that RCS/RI has a big interest in
it, but we might run out of time before we can set up a mover. A cormer of
a garage might be nice for just a short time, just in case the machine's
current owner needs the thing out of the San Diego place on short notice.
If RCS/RI just can not pull this off, does anyone want the thing?

Ok, since I intend to use this thing to work on computer related gear older

inquiry off-limits for random flamage! B^}
Does anyone out there have info (like the tube/switch charts) for an EICO

shape, but is otherwise useless without the charts for switch settings.

I'll be having fun friday...
I get to go argue with a professional junk guy over a KS-10. The company that
owns it wanted it melted down, to protect some confidential data they had on it.
SO, I'm gonna say "None of your data is on the CPU, just the disk packs,
so he can have the packs. There." The drives are 2 RP06es. (Yes, I know I
need 3-phase. Mark says he knows where to get an RM80 or two. Is there
any way around having to have 3-phase for the RPs? I was told they fail every
other 10 minutes, is it even worth it?) It did run TOPS-20, but I'm chasing
after ITS tapes for it. Even if I don't end up getting it, I may get the CPU
cards and backpanels, and then I know someone who has the rest of a KS.
Failing that, if the junk guy gets everything, I know someone else who has
a whole KS, but no operating system. So, one way or another, we're gonna get
a running ITS installation out of this...
Am I supposed to be this nervous?
I've never had to actually argue with a junk guy over a machine, in front of
a buncha suits... (Division heads or something. The actual company is QUITE
large... *hint* *hint*...)

You can't have mine.
MINDSET was about as you recall. It built in 1984 as a super-multimedia
80186-based PC-compatible (well, mostly-compatible, anyway.) For 1984,
the graphics were superb and it had (IIRC) a video-in connection so you
can use the computer as a character generator/paintbox. I think it was
packed with a low-end cousin to the Time Arts Lumena paint program and
was THE machine for graphic artists. Remember, this was a year and a half
before the Amiga - which, whene IT came out, pretty much took over
Mindset's market.
The Mindset has a unique and quite beautiful white bi-level case design.
So pretty in fact that the Museum of Modern Art put one in their design
collection - the first computer placed in their collections.
Much of the hardware was proprietary - weird memory modules and it also
accepted plug in progrram cartridges.
Mindset didn't last too long as a company. They DID build a second model,
an AT-based machine in charcoal gray. I've seen it once and never read
anything about it
I found my original Mindset last year, complete with a couple of
expansion RAM modules, the boot disks and the paint cartridge.
Like I said, it's gorgeous and you can't have it. Nyah. But - I might
make you a deal on the stereo module!

I saw a CDC demo of that once circa 1974, as I recall it was
called "Plato", used a nice orange plasma display, limited
animation, astronomical price. CDC had grandiose plans it would
be used in schools, like every high school in the country could
afford a $2 million CDC 6600 to support it. Kinda sad actually,
once Cray left CDC they didn't have a clue as to what to do
afterwards, the big iron Cyber 6000s went nowhere, the company
wound up running payroll services (the remnants of CDC are now
known as Ceridian, a batch payroll services company).

Time to clean out at least part of my garage, especially in light of the
new arrivals. All offerings are freebies, though it would be nice if I
could get -something- in trade. ;-)
Please bear in mind two things.
1). I cannot ship anything other than the books. The disk and tape drives
are too darn big and heavy, and would require specialized packaging in any
case.
2). Dave Jenner has first pick since he E-mailed me this morning before I
posted the list. I'll post an update if he wants any of the stuff.
With that in mind, I have the following to offer:
1). HP 7974 9-track vertical tape drive, with all mounting hardware. 1600
BPI, Pertec interface, supplied with the hardware to convert it (if
desired) to a GPIB interface. Excellent condition, powers up and loads
fine, have not actually tested it with a working system.
2). (Definitely a freebie!) 83-84 vintage System Industries SMD disk
drive. Spins up, makes lots of noise, don't know if it works. Comes with
mounting rails.
3). Cipher 880 tape drive, dual-density (1600/3200). Condition: Who knows?
Freebie.
4). Books! I've got spare copies of:
DEC's 'Microsystems Handbook' for 1985
DEC's 'Introduction to Minicomputer Networks' vintage 1974
Everex 'Step 386' owner's manual
DEC PDP11 'Programming Card' quick-reference, vintage July 1975
DEC DHV11 Technical Manual.
Any takers?

Yup, they made desktop PC-compatibles for a while. I remember a
dealer in College Park, MD selling them (Software'n'Things if anyone
else out there remembers them; to the best of my knowledge they aren't
operating under that name anymore if at all).
One of the big selling points was that they were upgradable by virtue
of the passive backplane. Buy an XT-compatible now, later on you can
upgrade to an AT-compatible just by swapping the CPU card for the '286
flavor.
BTW Doug, is that your face I saw gazing up at me from this morning's
San Jose Mercury News? If not, there's some guy calling himself
Doug Salot who has some stuff in his collection that's an awful lot

When someone says Line Printer I think of something with the type
on a chain (or a drum) and the ribbon in front of the paper, and then a
bunch of hammers behind the paper. When the right character is in
front of the right position, the printer fires the hammer for that
position and pushes the paper up against the ribbon and chain/drum.
But the real definition is in how much data you have to send to the
printer to get it printing. If you have to give it a full line to get
it going then it's a line printer. If you only have to give it a
character to make it print then it isn't.

Is this "pod" something that clamps over an installed CPU? There is a test

Dave Jenner has bowed out on all items in the list I posted. Sam has

Well the F8 while known was not hobbiest fodder being aimed at embedded
systems. Same can eb said for z8. The 9900 as I refer to it was not the
TI99/4a(have those too) but a Technico SBC, due to a lack of TI support it
was not that popular. However the TI99/4a is still quite popular.
Others I've worked with 78pg11(uCOM78) were aimed at embedded
applications. I might add that my time as a product engineer at NEC in
the early '80s had me designing in that part as well as supporting it
along with ucom4 and ucom75 4bit micros.
The RCA1802 was sort of a square egg. It had popularity for a short
while. People lost interest after that, partly as RCA discontinued
it by the mid 80s. Also because it was slow and had a relatively
poor(primitive) instruction set and a total lack of high level languages
other than tinybasic.
The advent of more complete systems like apple and trs80 and decreasing
prices helped focus the market on two key players 6502 and z80 and it
would remain that way until the 68000 and 8088(x86) would displace them.

Well, do you know if it's oiled or unoiled? I'm not sure but I think I
may need the oiled. I need to ask someone. My wife says that this tape I
have has the distinct smell of machine oil. It should make the punch block
last longer.
I was just going to order a 1/4 case from Western Numerical Control
(http://www.westnc.com/paptape.html). That's 7 rolls for $33.00, in
all kinds of colors. And they are close by in Grass Valley,CA.
I also want to ask them about the toxicity of paper tape. (My two
sheppards think everything is a toy for them to fight over.)

First off 2016 is a byte wide ram. I sounds like someone stripped the
card. The SBC-1 was a complete Z80cpu(4 or 6mhz)/64kram/eprom/IO card
it was designed to be used as a slave to the Systemaster cpu card. The
2016 was used to create a FIFO so that block IO coul be used to
communicate with it. the only thing it lacked to be a complete S100
cp/m system on a board was disk IO. The system master card had all that
and FDC as well.

I didn't quite mean that :-) I was just interested to note that some
micros that were once well-known aren't well-represented in your list, or
Allison's, or mine. Only one occurrence of the 9900, no F8, only one
Cosmac, ... Perhaps three people is just too small a sample to show all
of the ones that faded from popularity (and maybe nobody else here is
interested :-)) Not a lot of DSPs either, though of course they're more
"modern".

I have been rearranging my storage area and uncovered a HP 1611A Logic State
Analyser fitted with a Z80 option that I picked up a few years ago.
I have no idea what one would do with this. Should I cherish it? Play with
it?
Does one need the specific manual or are these generic and perhaps explained
in standard texts?
There are a number of plugin points for various types of probes, none of
which I have off course. It powers up fine though.
Indeed, what a haul (at least if you're into DEC stuff).
Thanks to the kindly folk at St. Martin's College about 40 miles south of
me, I am now the proud owner of:
* A PDP-11/44 and its rack...
* A Fujitsu 'Eagle' drive (and it's weight!)
* A Cipher 880 front-loader tape drive...
* Numerous distribution tapes for several versions of RSTS/E, including
one for ver. 9.7(!)...
* Various bits of documentation. Unfortunately, not a lot on RSTS itself
(much of it got trashed along with the -- get this -- distribution kit for
RSTS 10! Dang, I was pissed when I heard about that...)
And, thanks to my friends at RE-PC, I have also acquired a pair of M4 Data
model 9914 9-track SCSI tape drives. These are neat boxes! Quad density
(800/1600/3200/6250), autoloading, neat front panel with alphanumeric
display, etc.
It's been a busy weekend. Now, if you'll pardon me, I need to go collapse
and snore my brains out. ;-)

DOS 5.0 on it. The nice thing about this is that most of the chips are

By and large including the 8008 and VAX I've programmed and designed with
all. The key thing is I have working examples of all but the 8008.
Drat, I forgot the NEC unique 4 bitters the uCOM4 and ucom75 series
designed them into and programmed them as well.

They were used for calculator like and control systems. The word width

How about the CAI system that CDC had (I can't remember the name off hand

brand name of some wine I wanted to buy yesterday... Will chewing on a

that the CDC thingy :-) had a browser style interface.

They "formed a partnership" which, amongst other things, involved the
exchange of some $90,000,000.

The Wang patent relates to videotex terminals, exactly the stuff that
British Telecom developed in the 1970s and pushed hard (as PRESTEL) in the
early 80s. Prestel was organised a little like an ISP, with various "IP"s
(information providers) renting space in which they creating "frames" of
text and (chunky) graphics which were accessible by modem. IPs could
sublet space, too, so individuals could rent just a single frame if they
wanted.
In 1982 PRESTEL launched a service called Micronet800, which used thousands
of pages on PRESTEL servers to store microcomputer related news, software,
etc, and started selling software to enable home micros to dial up and
display/load/save these pages. Actually, stuff for micros had been around
on PRESTEL before that, but spring 1982 was when it took off. I got my
software and modem that summer. Most of the modems were simple devices
built in to an acoustic coupler, fondly known as agnostic complicators.
PRESTEL itself didn't make use of file extensions, but obviously some of
the micro systesm that accessed it did. CP/M has always based certain
actions on file types and extensions, for example. It did use menus of
links, and the links between frames, could be quite arbitrary (and
tangled!) just like the web. There was even a command to go back one or
more frames, and there were "response" frames and a mail system and ...

As far as commonality of old machines goes, most airports have
old machines. Public libraries do as well. The boston public
library just replaced some Vaxen with Alpha machines. I couldn't
get them to tell me what they did with the old stuff.
In general, I would say that the amount of old machines is greater
than a given reasonable estimate (ie there's always one more).
Also, I'm wondering how many simple cash registers will have to be
taken out of service.

Anyone want to buy an Osborne 1 for $1000? Didn't think so. However, if
you're interested in trying to talk this guy down to reality, I have the

Oops. Too much gin in the tonic water tonight.

The original poster stated that he was passing a NULL POINTER to strcpy. You replied that it should be OK to copy from a NUL STRING. I understand the difference and was trying to casually point out that you were not addressing the question asked. Sorry if I ruffled some feathers.

Yes, but that's not what I wrote. A null string is an empty string (no
characters). A NUL string would be a string with a single ASCII NUL
character in it -- and rather hard to manipulate in C, since NULs mark the
ends. Nevertheless, they do exist, though that wasn't what I was talking
about.

But you can't easily use both sets of registers at the same time (yes, I
know we sometimes do, but it's a fiddle) and the Z80 is very much a
single-accumulator type of beast. And as for IX and IY ;-)
The original design of the 6502, incidentally, was that all of zero-page be
treated as registers. They just happen to be external to the chip, which
wasn't completely unknown elsewhere in those days. So in that sense it is
possibly the most register-rich design of the era -- but the registers are
hardly general-purpose, and the 6502 is also a single-accumulator design.

If you count all the ways you can index with registers, MIPS processors
have quite a few addressing modes. Not all are used very often, though.

The 6502 has a certain elegance of instruction set. Quite a different
philosophy to the Z80, in many ways, but I like them both. We used to say
that you had to learn how to use the 6502, and when you did, the code was
neat, but on a Z80, you just had to decide what you wanted an instruction
to do, and then pick the one that did that. Exaggeration, of course.

Showoff :-) No 8008? I always wanted a 4004 (anyone listening out there,
that's a hint) and an SC/MP. Anybody remember Fairchild F8's?

Well, I've got all of those, and my favourite is the ARM. I've had to
write MIPS assembler, and it's not great fun.

Well, whether I think that's sensible or not ('cos I think you ought to be
able to copy a null string), if ANSI says it's undefined, then it's not a
bug. I take it back. And thanks for checking, which I was too lazy to do
:-)

Yes, I should perhaps have mentioned mailing to postmaster@... or abuse@...
as several responsible ISPs do follow these things up. I've had two very
positive responses from sysadmins, one of whom tracked a spammer who was
spoofing via his system, and one from a large ISP. In both cases, the
culprit lost their account. It's worth looking at all the "Received: from
..." headers in such cases.
