The recent talk of various Tandy clones made me wonder how much hardware
has been knocked-off over the years. These are the ones I know of:

Original Clones
------------------------------- -------------------------------
IBM (PC/AT/etc.) [Billions and billions...]
Apple II(+/e/c) Franklin (1000/1200), Laser 128
Tandy Color Computer Dragon 32
Tandy TRS-80 Video Genie
Macintosh [Rumored. Asian and American.]

Anything else?

Amdahl cloned IBM mainframes in the '70s. I think Terak cloned the pdp-8.

I have read that the Soviet Union supported exactly 3 architectures at
one point: Clone of Intel 8080, Clone of DEC pdp-11, Clone of IBM 370.

WRONG. Terak 'cloned' the PDP-11 (actually, LSI-11).

No, -11,

And the PDP-8. They called it a "TPA" I saw a picture of it; looked just
like a PDP-8/l. The article pointed out that it was non-DIN compatible.
(I think DIN was what they referred to their 360/370 clones.)

What about RCA's Spectra-70?

There was a BYTE article years ago about a Soviet clone of the Apple ][. It
was called the Agat, as I recall. Wierd, wierd machine.

I refrained from mentioning this in my list because it's not
technically correct. Terak used the LSI-11 chipset, but their
machines weren't exact pdp-11 clones, and if the instruction
set is all that counts, there isn't much point to the discussion.

I don't think the Dragon 32 was so much of a clone, just that both
machines were built to similar (Motorola) specifications (same video
chip, same Basic, same memory map..). That was the story I heard,
anyway.

The Siemens (barf) series of BS2000 mainframes were IBM mainframe clones,
one could run the Siemens proprietary system (no comment ;) or IBM MVS.
I believe, the cpu itself was made by Hitachi, can someone correct me here?

My understanding of the Hungarian rip-off PDP-8/l was that it was called a
"TPA". I saw a picture of it where there were two of them placed one over
the other, complete with the front panel and switches. Except for the Digital
logo, I could swear they were made in a famous former woolen mill in New
England :-). The article pointed out that they weren't compatible with
IBM 360/370 knockoffs, and that the picture shown was a "multi-processor"
configuration. Yeah! PDP-8's used in multi-processors? (Give me a break; this
was just a picture of two machines in a little pile!)

Obviously portions of this were just a little cold-war propaganda.

In 1967, I went the the world's fair, Expo '67 in Montreal. The Russian
pavillion was designed to awe the technologically ignorant. There was a
hoaxed model of a Russian-designed transistor radio from 1935 :-). On
one side was an exhibit of pseudo-hyped electronics: some crystals not
even as good as Army-surplus WW II crystals were displayed as "Piezo-electric
Resonators" which of course is accurate, but hardly technologically advanced.

The whole building had a cute light-chaser display through it, but hardly
of technical achievement value.

To contrast this, the big deal about the American pavillion was that Brian
Wilson's guitar had been stolen :-).

It couldn't really be considered a "clone". The user instruction set
was the same, but the supervisor mode (and instructions) was different.

Hm. Not exactly. It's a public display of stupidity of communists
(if you've got to be not a party member you could forget about
travelling abroad, leave alone preparing exhibitions).

Model was surely a hoax, though the first semiconductor circuit able to
amplify signals was indeed invented by Losev in '35 (it was called "crystadine"
and basically was a kind of tunnel diode, not transistor).

Pfrrr. Aren't those modern quratz oscillators you can found in every piece
of electronics are basically the same? I doubt their quality got really
much better since WWII. And crystallography always was a strong science in
Russia. Though, i believe the packaging was pretty ugly.

The decline in Soviet electronics started at about 1970, when a bunch of
ministries was created to rule the new industry. At the time when electronics
was considered a branch of the space/nuclear project it was quite at the leading
age in Soviet Union. Even now the Soviet military electroinics is generally
considered pretty dumb but working under any conditions. Doing complex things
with simple circuits became a kind of art :-) The same applies to mechanics --
look inside the Kalashnikov assault rifle -- it's unbelievably simple and
effective. As a matter of fact, the American high-tech gizmos was always
a target for tongue-in-cheek remarks about killing a fly with a barrel gun.

The common rule in (ex-) Soviet Union was that research and engineering was
quite at the level. The production was (and is) a disaster. To produce things
you need a working economy. To invent them -- quick guts. An empty stomach
was always considered a booster for creativity 1/2 :-)

I did; maybe my article hasn't propogated yet.

Given DEC's failure with the Jupiter, the Foonly (offshoot of the SuperFoonly
Project at Stanford) family was a nice successor. The F-1 was a real number
cruncher (and only one was ever built); the F-4 was the "common" model and
I believe its primary customer was the military, though the old Office
Automation project ("Augie") from SRI-International ran on some. One of my
commercial products ported to the F-4 in almost no time, but there were a
few minor problems since the Foonly systems ran Tenex and my product was
TOPS-20 based (TOPS-20 had quite a few more JSYSs than did Tenex).

Only saw one Systems Concept box; it was in use at LOTS (Low Overhead
Timesharing System/Service/whatever) at Stanford. I remember opening the
cabinet and asking "Where's the computer?" since the thing was so compact
yet was placed into a standard "rack" case since that's all that was
available. Incredible machine; was about 6x the power of the KL-20 CPU
and ran TOPS-20 without any change.

Someone in another newsgroup recently mentioned that SC's "problem" was one
of marketing; they engineered an incredible system, but hadn't the marketing
acumen to sell it. 'Tis a shame.

HOWEVER (and note I recently mentioned my desire to play the ol' games Zork,
Adventure, HAUNT, Fisk, and LUGI), I have been informed that several people
who've left a well-known Menlo Park CA networking company have set up shop
up near Seattle and will soon bring to market a desktop DEC-20; this will
really be a "turnkey application box" which "just so happens" to run TOPS-20!

Though I wasn't sworn to secrecy or placed under non-disclosure, I won't
say any more because I don't want to spoil their pending announcement(s)
[which hopefully will be soon].

No, Xerox did NOT make any IBM clones. They took over and tubed Scientific
Data Systems (SDS), called it Xerox Data Systems (XDS) and they made
their own machines. The structure of the 32 bit ones was similar to IBM 360's
but a bunch of things were different.
Same:
8 bit bytes
I/O channel structure (some even used the same channel IO codes)
EBCDIC (good, or bad take your pick)
Different:
Floating point numbers (negative ones were 2's complement, not sign/magnitude)
Indexing methods
No seperate floating point registers
Instruction sets
memory capacity
paging methods

They were really not a bad machine, and with proper stuff, timesharing did
happen (IBM's TSO was a different story).
Smaller configurations could be limited in scope though.

If you call DG's Nova's clones of PDP-11's then the comparison of clones might be
valid, but not otherwise.

It looks like no one has mentioned that (be ready for a surprise) the
TI 99/4A computer was cloned. I can't find the ad I once saw to figure
out what the name of the company was, though.

Talk about bad decisions. Riding the coattails of one of the least
successful micro manufacturers...

The Sinclair ZX Spectrum (dunno what it was called in the states) has been
cloned in Russia, and was apparantly quite a good seller. Can't remember what
it was called though. The Pearcom II was also an Apple II clone IIRC.

The Sigma-9 is considerably different from a 360. In fact, I can't
think of much in common except for the word length and two's
complement arithmetic. Even the notion of the EBCDIC character set
was different (something that took me many long nights to notice.)

I worked for a time on a Siemens 7881 running BS3000; that computer was
actually manufactured by Fujitsu, the OS' orininal name was MSP, and it
was an MVS clone. The manual for the Fortran compiler was a nightmare,
and so were the error messages. Linking a GKS graphics program on that

Doesn't Siemens hold 20% of Fujitu stock or something like that? In
Germany, they also market and support Fujitsu's VP series. Now, these
are FAST computers...

I don't know for certain if it's true, but I've read somewhere that
a company named _Scientific_Computing_Systems_ (SCS for short) did a
Cray-1 clone. Or maybe it should be called a "Cray-1-compatible machine"
since it was supposed to have considerably less brainpower
(and smaller price-tag...) than the real thing.

No, but the 64k model (Dragon 64, surprise, surprise 8^) had a floppy

The classic computer clone appeared in the early 1970's. A company whose
name slips my mind saved hundreds if not thousands of engineering hours
by photocopying Data General circuit boards to produce a clone Nova.

Data General sued, won, caused the company to go bust, and took over
the factory to make more real Nova[se].

Try using the DB8-E Interprocessor Buffer, but as I understand it, this
certainly doesn't give you a tightly coupled pair of processors.

Speaking of clones, ROLM made the RuggedNOVA under licence from Data General.
It was a Mil Specs version of the Data General Nova.

Not so. The original product spec was to produce a machine which
would look familiar (I think that was the phrase) to a 7090 but the
instruction sets for the 6[23]5 were definitely not the same. And of
course the 645 designed for Multics was even more different.

GE DID byukd a cute hardware emulator box that looked like a CPU to
the memory, ran the 7090 omstruction, and farmed out work to the real
CPU by pretending it was a memory.

For many years the VAX seemed to be the computer of choice for the Eastern
Bloc to try to smuggle. One of the Eastern Bloc countries (Bulgaria I think,
may be Hungary) reverse-engineered a VAX 11/780 and started making their own
under their own name (I forget what they called it). They were supposed to
be very faithful copies.

What's funny, with the fall of Communism and Digital opening offices in
these countries is Digital started supporting these clones.

Hungaria never managed to clone VAX, the machine you're talking
about is CM 52/12, Chekhoslovakia (sp?) -- i had a fortune to
use one; though it seldom worked a day without ugly crash.
Soviet VAX-en were much more reliable (SM-1700 and Elektronika-82).

But the machine of choice was PDP-11 :-)

They started using existing facilities and personnel trained on

Seems I wasn't dreaming after all. A few random quotes from "Parallel
Computers 2" by Hockney & Jesshope (pg 51-52):

"The second minisupercomputer to be announced was the Scientific
Computer Systems SCS-40 which appeared in 1986. Like the Convex C-1,
the manifacturers claim that the SCS-40 delivers 25% of the
performance of the CRAY X-MP/1 at 15% of the cost. However, unlike the
C-1, this machine uses the CRAY instruction set, and CRAY programs
should run without alteration. [...]
[...] LINPACK benchmarks for matrices of order 100, [...] the SCS-40
reaches 7.3 Mflops/s [Comment: 24 for a single X-MP processor
according to a table in the same book.] [...]
Recoding of the LINPACK benchmarks in the terms of matrix-vector,
rather than vector-vector operations, improves the performance to 26
Mflops/s for a matrix of order 300 [Comment: 171 for an X/MP]."

I can confirm this from firsthand experience. When I was a kid in Hungary,
my father worked on this machine, model number TPA-i1001 (or some such).
I saw the machine quite frequently in 76-78 (even wrote toy programs for it),
and it certainly looked like a PDP-8 from the outside (I never saw the
inside and wouldn't be able to make a comparison even if I had). Although the
machine was itself made in the Eastern block (don't remember if it was
made in Hungary itself or not), my father and his colleagues actually used
manuals for the instruction set etc that in retrospect must have been
supplied by DEC itself, although certainly not directly to their eventual
users. (I don't think anybody in Hungary would have gone to the trouble
of copying a DEC colour scheme on the cover given how difficult to obtain
colour printing, or in fact any printing, was then.)

A true story about this machine. It was installed in a building in central
Budapest that happened to have a subway built underneath it. The subway
construction caused half the building to subside several centimeters while
the other half stood still. This required the use of whole tree trunks to
prop up the structure of the building, and a restriction was placed on
the amount of weight that was allowed to be on each floor. The machine
itself fit in the weight limit, but its airconditioning unit did not.
As a result, my father often left very early to work, the idea being to
run programs until whatever time the machine overheated, at which point
it would crash (or start to give random results; I don't remember which).
He usually got about two or three hours of useful computing per day, more
in winter if the central heating was not turned on. Convincing the powers
that be that this was a very inefficient use of a very expensive machine
turned out to be impossible.

Not quite. Probably the original motive for the GE 600 line CPU was to
replace 7090s in military/aerospace applications. It was designed at
one of the GE military electronics facilities. But it was not instruction
set compatible with the 7090 at all; it was a somewhat more modern machine.

However it was taken over into the commercial computer line, with a great
many teething problems. The commercial versions were models 615-625-635.
Hoping to capture some 7090 customers, especially those who would rather
switch than fight the change to 360 architecture, GE designed a combination
of hardware and software called "9SA" which was short for "704x/709x
simulator aid" The hardware connected to a port on the 635s memory and
also to a memory port on the processor. It executed a portion of the
704x/709x instruction set, mainly the fixed point arithmetic and the
control instructions. It read 7090 programs right out of memory when
doing that. When it came to an instruction it didn't support, it would
interrupt the main 635 processor, which would software-interpret the
instruction, reading values from the 9SAs registers and putting the
results back into them.

The intention was for 7090 customers to buy GE machines and use the
9SA for as long as it took them to convert their programs to GE native-mode
code. Then the 9SA machine would be taken away and sent to some other
customer. As things turned out the customers took a lot longer than
expected to convert their programs, so there was a shortage of 9SA
machines, but it was countered by the fact that fewer than expected
customers switched from IBM to GE.

I haven't seen any mention of the copy of the PDP 11/35 that came out in
the mid-70's. My recollection of this machine is that it was a copy right
down to the ROM's, although there were cosmetic changes to the case and
front panel, including color (orange and yellow?). There was also some
problems with software licensing, I believe.

DEC sued, and I think the producer went out of business. We had one of
these at the college I worked for at the time, and we junked it when we
couldn't get parts.

A small aside - At about the same time, I was doing some consulting for
a typesetting firm, and the owner had two of these at home (one for
spare parts). His son, about 7, would come down, boot the machine,
and play adventure... They also had one of the early micros, I think
it was an Altair, that was supposed to be the kid's machine, but he
thought the PDP was far more fun.

The Soviet Union cloned the Apple II, and they also completely cloned the

Byte reviewed the Soviet Apple II back in the early 80's. I still have the

in this country.

Data General NOVA Digital Computer Controls 'D-116'

and later, many machines using Fairchild 9440 microprocessor were
also NOVA clones, in some sense.

There was a DEC PDP-10 clone called the Foonly. Only a few went into
operation...

Maybe they should have run ads like Smucker's jelly: "With a name
like Foonly, it's got to be good."

I didn't think DEC sued Foonly.

The Dragon ran all Tandy Co-Co software.

The Dragon 32 never ran OS-9. The Dragon 64, which was launched just
before Dragon Data crashed, could however.

At least to some extent, so did Xerox. :-)

(How different *was* the Alto's "BCPL instruction set", or whatever it
was called, from the Nova's instruction set? And is there any truth to
the claim that the Alto's "BCPL instruction set" was Novaesque because
they already had a BCPL compiler for the Nova and it was easier to build
a Novaesque machine than to roll a new compiler?)
