Since I have never seen the 8800BT, I'm sure it is rare, at least he says a number of times that this stuff is RARE. Shipping and handling including insurance is only $100 plus the winning bid. However, it does have some good photos of the unit. http://cgi.ebay.com/aw-cgi/eBayISAPI.dll?ViewItem&item=35408024

Some "Classiccmp-Friendly" pinouts posted....

by aaron＠wfi-inc.com

After being frustrated trying to view some of the pinouts posted on the web with lynx (everyone using frames/tables/etc), I have created a shell-user-friendly pinout directory on my web server. I've got ~75 of 200 (give or take) up so far, and I'll be working on it for the next couple of weeks. http://www.prinsol.com/pinouts/ If you have the time and the giving spirit overcomes you, please share any that you find missing. Especially those from scarce/rare/unusual machines that might help someone who rescues one with no available documentation. And for God's sake, please let me know if I screwed up on any of these, before someone trusts my addled transcriptions and blows something up! Related, but a little more selfish, could someone give me the pinout for the HP-IB port? Aaron

A couple of quick snags from the local thrift: Wyse-60 terminal, no keyboard: $4.95 "Programming in Assembly: Macro-11", E. Sowell: $.50 Someone posted a couple of days ago that they got some Wyse keyboards? Anyone have an extra for the model 60 that I just got that they would part with for a few $$$? Aaron

auction grabs

by CharlesII＠nwonline.net

My dad recently came accros some intresting stuff at a county auction. I wasn't there or he would have baught more stuff :-) but however he did find some keyboards that look like they came from a terminal and a computer. Does WYSE ring a bell to anyone? But the biggest enigma is an IBM 4224 printer which from the diagram on the back look like it was made for some sort of LAN, but not ethernet. The plug it would take would be about an inch in diameter. This was previously used by the board of elections and in that case was probably was wired in some sort of esotaric network. The other puzzel is an ethernet card that is deffentatily not 10 years old but just bear with me. The face plate already is a dead give away that it is not made for a PC. The other thing is that the interface to the computer uses a plug that has 3 rows of 32 pins. Could any one tell me wat this interface is, and what I could do to adapt this to be used by a PC's serial poart? Another find was in the tons of IBM formated disks I found an original wang floppy disk but without the orginal format :-( Thats all for now.

I did get a chance to do some F8 programming about 1982 at AMF's Electronics Research Lab. I had to modify the code in a rowing machine. They added a clip for the ear lobe that measured your heart rate. I used a 3870 because I could try out new code by inserting a new EPROM on to the processor. I did burn out one of the 3870s and I stuck a white ceramic 1702 on top and made it into a tie clip to remind me. That was the only processor I have every destroyed. And I still have it today. As for the instruction set, the only thing I remember is that the ACC was always trashed on a return from subroutine. I think the processor use it to pull the return address from the stack.

Pre - Columbus traveler with classic computer?

by maxeskin＠hotmail.com

The chief advantage of any kind of history is, IMHO, to reach the understanding of how similar the past is to the present. This applies to computer history as well. Only people who are familiar with it know that the computers we use today (except uncommon parallel and analog computers) are based on Von Neumann's theories more than 30 years ago. There is no real advancement. There is multiplication of matrices by a scalar value... There is nothing new under the sun, as a very old book says. >As mor as I learn about this 'dark ages' as less dark they >apear.

Trust me on this; I've got the docs. and the story of it's development from an Intel person responsible for it. Some parts of the silicon may be similar, but it was designed from the ground up as a video display chip for some sort of consumer electronics. My point was that it wound up being used is just this one application (the Maganvox Odyssey^2/Phillips G7000) and never made available through other channels. I was just pointing out that the 8244 has some capabilites that were not used in that application. What I find so attractive about it (and all the stuff that era), is that it respresents a window in time where the basic foundation blocks for todays stuff (which we take practically for granted) was developed; and the limitations they had to work under (i.e. not practical to have enough memory for a direct bit mapped display, the state of chip fabrication and design, etc) which were unique to that time. I comapre it _alot_ to the automobile industry between 1898 and 1914.

Fairchild Channel F units

by MPritchard＠EnsembleStudios.com

The Democarts, (both of them) and #19 are very hard to find. From talking with other collectors, the democarts appear to be slightly more common. Personally, I have a Channel F, Boxed Channel F II, and 23 of the 28 carts; but I don't have #19, or either of the Democarts. There was also a picture of a keyboard controller (K-1) on the box for Channel F II. Perhaps a prototype exists for it. As I recall the F8 was a microcontroller in the same vein as the 8048; but that it multiplexed it's address and data lines; allowing for fewer connectors on the cartridges. I think it also had 64 bytes of internal RAM; organized as set of registers (sorta) which probably means that there was no ram in the system. I suspect the Channel F R&D effort was a rather small one; I had a chance to learn about the R&D effort behind the Magnavox Odyssey^2, and discovered that there was only a handful of people behind it doing the actual development (one guy wrote half the game library) and that it had very poor support from management at magnavox. All throughout the history of it, from 1978 to 1983, they were always told "this will be the last stuff you do for the O^2, then we pull the plug" and each time they'll sell out the latest run of carts/systems and be given a reprieve. management finally became serious about it in 1983 just in time for the video game crash. The Odyssey^2 had an Intel 8048 with a 512 byte BIOS, 128 bytes of RAM (don't recall the chip) and the video (& sound) was driven by the Intel 8244 chip - the only application the chip was ever used in; (trivia - multiple 8244's could be hooked together with the output of one (slave/master mode) being fed into the next one. Intel shows no reference to the chip or any mention of it in their archives, but I have the story on it from the horse's mouth (and the data sheets :) ) Somewhere, way way back in my archives, I have a copy of a post from someone who claimed to work at Farichild way back when (and knew about the channel F). I should try and dig it up someday to see if he could be tracked down. -Matt Pritchard Graphics Engine and Optimization Specialist MS Age of Empires & Age of Empires ][ > -----Original Message----- > From: Francois [SMTP:fauradon@pclink.com] > Sent: Monday, October 12, 1998 9:11 PM > To: Discussion re-collecting of classic computers > Subject: Re: Fairchild Channel F units > > >#19 is the hardest to find. > > > How about the demo cart #2?

Wyse Systems (was RE: auction grabs)

by jsalzman＠hersheys.com

I worked for a company once as a service tech fixing CPT Word Processing systems. When PC based word processing started to become popular (mid '80s), CPT bridged the gap between their longtime standalone word processing units and desktop PCs by using Wyse PC clones (the ones with the blue backlit LCD display on them). They primarily consisted of a clone style case with an expansion board. The CPU board plugged into the expansion board like an add-on card and was primarily an entire 286 or 386 computer on a card. The keyboard connector was an RJ-11 with an optional DIN adaptor for conventional keyboards. The other card typically found in the system was a bridgeboard which was an entire CPT system on a card with a monochrome video out. The 2 cards talked to each other and became a full computer with built in CPT word processing simultaneosly running along with a DOS/windows based environment. The monitor was a portrait style page white display. The on screen display could be split to show DOS on top and CPT on the bottom or made to show a full screen CPT system as the CPT systems were originally designed. Many govornment agencys used these systems to bridge their own transition from dedicated word processing systems to PCs. Jeff Salzman >> > computer. Does WYSE ring a bell to anyone?

Pre - Columbus traveler with classic computer?

by Innfogra＠aol.com

In a message dated 98-10-13 03:37:16 EDT, you write: << is true that sailors in those days were leery of sailing too far from coast -- because there was no way to determine longitude until accurate clocks were developed many years later. >> We know now that the Egyptians knew the 25,000 mile figure around 700 BC and possibly much earlier. Recently they pulled a brass differential geared device that may be an astronomical calculator from a wreck in the Mediterainian that dates back to 300 - 400 BC. I bet the device is older yet, it is hard to carbon date brass. They recently discovered settlements on the south coast of Chile that date back 30,000 yrs. I believe that there was regular but infrequent trade & travel between Egypt and South America 4000 years ago. My question is which way did they go, the long way, via China, the Bearing Straits and down the west coast of the Americas; or did they go the short way, which is from the westernmost tip of Africa straight across the Atlantic. This distance is is shorter than the length of the Mediterainian. If you were able to calculate the distance one had traveled by going the long way (I think this was done first); I would think that the short way would become obvious. To get back to classic computers, I bet this brass device is one of the first computers, if differential geared devices count. My question is why did everything go to Hell between 300BC and 0AD? How could you believe the earth was flat? Where did this idea come from? Paxton

One of the driving forces behind the prevelance of non-Intel micros in the 70s was that Intel processors were expensive (actually they still are!). I think the 8080 was about $200 when MOS started selling 6502s for under $40. Of course with that Intel lowered thier prices (to about $100 or so). Not to say that the Z80, 6502 and others were bad CPUs, it's just that Intel was not looking for the hobbiest/home market at all, and if it wern't for a big business name (IBM) behind it it would still be looking for a 'killer box' (like 'killer app' is to software) to be used in. And IBM was known for the safe route, proven chips and designs, (no innovation made cloning alot easier) and Intel had the name and a good track record among business machine microprocessors. -- -+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+- Larry Anderson - Sysop of Silicon Realms BBS (300-2400bd) (209) 754-1363 Visit my Commodore 8-Bit web page at: http://www.goldrush.com/~foxnhare/commodore.html -+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-

Thanks for the help.

by Aaron_J_Hayden＠student.ferris.edu

I'd like to thank everybody who gave me info on the PC Jr. I got it going late last week. It turns out it needs two power supplies for the cpu. Apparently the people who owned it before me had it upgraded and the upgrade requires it's own power. I saw the second power plug, but it wasn't marked and I didn't think of it needing a second supply. Anyway, it runs like a top now. All of the info was greatly appreciated. Aaron

Cipher F880 9-track Docs/Schematics

by aaron＠wfi-inc.com

I was cleaning out the garage and came across my one real documentation treasure, the doc binder for my Cipher F880 tape drive. The nifty thing is that they put all of the schematics, engineering data (including a price breakdown of every individual component), and mechanical diagrams (lots of blowups) in there too. Does anyone have a pressing need for this documentation? I won't give up the original, but if someone expresses some real interest I could scan it in and post it on a web server or something. It's a lot of material, but it's interesting that they give so much detailed technical information in there. I'll get around to it eventually anyway, just for archival purposes... Aaron

MMD-2

by yakowenk＠cs.unc.edu

Hey, I've got a couple of E&L MMD-2's here. These are neat little 8080 educational SBC's. Hex keypad, "function" keypad, 7-segment LED's, and three sets of 8 LED's for I/O ports 0, 1, 2. Includes a cassette interface, bus expansion connector, serial interface, and even an EPROM programmer for 2708/2716's. Most impressive! But I didn't get any sort of manuals with them. I've figured out most of the obvious stuff, but it would be nice to know the format expected by the "load" function, the meaning of a few unlabelled switches/jumpers, the meaning of "BRL HI" and "BRL LO", and so on. Anybody remember these things? Thanks, Bill. PS. These things seem to be using the word "pop" to mean "burn", as in "popping an EPROM". Was this a widespread usage? I've heard the words "burn", "blow", and "program" used this way, but "pop" is new to me.

Microsci HAVAC

by Innfogra＠aol.com

I can't believe I am doing this much research on a computer I have already sold, but it is interesting. I found the Havac (that is it's name) in the "what's New?" column in Byte, May, 1984. It is an Apple work-alike and they also call it a transportable Computer. It uses the 6502 processor and a 164K 5 1/4" floppy. 64K of ram and 8K of rom and has high res color graphics. The manufacturer claims that over a 1000 Apple II programs will run on it. It is supposed to have printer, serial and Game ports beside the external floppy connector. It's suggested list was $850. I couldn't find an advertisement though, only the announcement. the good news is that I found a couple of boot disks in my archives which I will send to Kai. Paxton

It would seem to me the big differnece was the wave of colonization that resulted. Better put, the vikings were here. Columbus told the world two things, it's not flat and there are great riches in the east. Somewhere in ther is the difference in those explorations goals. < Yes this is OT, but it mirrors one of the recent arguments on ClassicCmp < and it could be argued either way because both arguments have validity. < It comes down to what the individual thinks is 'important'. True. The consideration is not the indiviual importance of any item but it's impact on the collective picture. What is significant is the picture was in some respects a collection of snapshots in time without continuity or context. There were/are pieces missing from the puzzle and it would be nice to fill them in. For example; Two of the oldest computing models Harvard and Von Neuman date back to the first machines yet they influence machines still. To make the picture complete we also need to know if there are other models and what they are. An aside to this is while Intel is currently the apparent successful leader en masse we still don't know how it will play over time yet to come. There have been near reversals in the past and it would only take the next design leap to change the current course. Also the industry is only 30 years old in a century where we are still developing fundemental technologies. My example for that is in the late 70s and early '80s everyone said that 16bit CPUs would wipe the 8bitters away. It sorta did, but not to the projected extent. There would be a wave of 8bitters like the Kaypro, ampro, SB180 to name a few in the 84-86 window and later. The 16 bit machine really didn't reflect enough of an improvement as the next level needed more. I'd say Apple knew (tripped on) this when they did the jump >from 6502 to 68000 (internally 32bit). It would be 32 bit cpus that would have the real impact. I expect that while Merced and Alpha are having an impact we have yet to see the next significant impactor. While we are going much faster, the way we compute is still logically similar to some very old machines. Allison

Strange computer... ATR 8000

by rexstout＠uswest.net

Picked this thing up at Wacky Willy's in Portland, OR for $5 with a floppy drive(actually two 5.25" drives in a case with a PS). Not quite sure what to think of it. It says ATR8000 SWP Microcomputer Products on the front, lighted power switch on front, and on the back we have two 13-pin Molex connectors marked Peripheral Out and Computer In, and three edge-connectors marked RS-232, Printer and Floppy Drive. Inside it says Software Publisher's ATR8000, and has a Z80 CPU, a WDC floppy IC and a VERY small amount of RAM... They assumed it was an Atari of some sort, as they recently got an 800 and 800XL. Does anyone have any idea what the ATR 8000 is? BTW, if you need some Univac disk packs(don't remember the numbers on it) they have two at WW's. Kinda expensive, they say they sell the platters seperatly to artists @$10 each. With 4 or 5 platters in each pack, you either need to shell out almost $50 or be good at convincing them that it's not worth that much(and it's not easy, I've tried before). BTW, it's at the Vaughn St. location, at the end of the Fremont bridge(US30 exit, then the Vaughn St exit from the exit ramp...). -------------------------------------------------------------- | http://members.tripod.com/~jrollins/index.html - Computers | | http://www.geocities.com/Area51/Lair/1681/ - Star Trek | | orham(a)qth.net list admin KD7BCY | | ham-mac(a)qth.net Portland, OR | --------------------------------------------------------------

by maxeskin＠hotmail.com

I maintain my stance that 'microprocessor' is a term used by the public and media to refer to a series of technical developments, that are not well considered before calling them microprocessors. In short, there is no way to define a microprocessor in the technical sense. TI's 1979 book Understanding Microprocessors defines it as: A digital integrated unit (or a set of IC's) that contains the digital functions necessary to be a CPU. It "processes" information and controls and keeps the system working in harmony as it responds to the step by step program that the CPU follows. Nice and circular :) >what a "microprocessor" is.

This is really way off track for cleaning boards unless they have been hit with a strong alkli (leaking nicads!), in which case a good dousing with vinegar (acetic acid) or lemon juice (citric acid) will neutralize that. Anyhow the PH and total acidity of a dishwasher unless useing something strange is fairly mild. Electrolytic corrosion (usually from ionic solutions and dissimilar metals) is prevented by quickly drying the board either with mild heat or forced air. Unless your water is bad (unsafe to drink) it is likely fine for washing a board. I've done this to 10-15 qbus cards, a Micronta DVM, and several s100 cards with the expected result, clean. I do it on boards I'll have to work on as it's less messy and in one case it cleared a short! FYI: I used to service marine radios when I lived on LI,NY and the procedure for dunked electronics was toss it in a barrel of clean water ASAP to get the salt out. This is repeated with several barrels of clean water to get all of the salt. Then the equipment is than opended, cleaned and repaired as needed (speakers, microphones, buzzers, enclosed coils). Generally speaking potable water is ok, mud worse (abrasive), salt is real nasty. Allison

Um, I don't care what anybody says, but that disk drive does NOT look like anything similar to an Apple Disk II.

But since most working implementations of an 8088 (the only one I have the databook for) require additional ICs, I'm wondering if it could truly be called a single-chip CPU. I mean, this thing needs chips for the clock line (8284, this says). It needs more chips for accessing RAM, and it needs RAM. Why do you say it's single chip? I think the only way to determine if it's a microprocessor is to look in the company's literature. If they call it an arithmetic logic unit, it's not a microprocessor. >failed to produce a working single-chip CPU before Intel. > >TI had a design, but it didn't prove to be manufacturable. > >Even if not everyone here agrees that being on a single chip is a necessary >condition for something to be called a microprocessor, to the best of my >knowledge no one disagrees with the claim that Intel as the first to make >a single-chip CPU. > >Eric > ______________________________________________________ Get Your Private, Free Email at http://www.hotmail.com

ckaiser(a)oa.ptloma.edu hath spoke: < Good think you didn't run it through the dry cycle, or chips like the PL < might short out (very sensitive to heat). The dry cycle is ok if the temperature is under 180f, too hot and it can over heat parts. I prefer the oven at 160-180f as it's drier and a bit faster. A blast of compressed air is also good for getting water out from under parts to hasten drying. The PALS while temperature sensitive and no more so than any of the LSI on the board. < Are you sure the soap wouldn't have hurt the solder or board traces, < though? Your kidding?

Items FS or trade

by rhblake＠bigfoot.com

Since I shut down the at home/on site business here and went to work as an ISS/CSS at a local corporation I need to do some cleaning out of excess here. I have many, many machines from 8088 through 80386DX that I can make a reasonable deal with someone on (not as cheap as an unknown condition thrift shop sale though) for mostly main units (you add the KB and monitor in may cases) but I have a few setups that are complete such as a 5150 PC that does have a 5151 monitor and original keyboard. PS/2's out the bung hole, Dells and AT&T's, etc. Many will have to be dug through when someone inquires about the condition and what it includes but 99% are in great condition other than minor wear and tear. I'm always looking for odds and ends for my machines here such as drives, cards, modems, etc as well as electronics test equipment for my bench. If you have something to trade rather than cash (which is my favorite, as is many other's) then let me know and we can go from there. Please email me direct so this isn't a problem with the list. I hate putting this on here but the people on this list seem to appreciate good sturdy hardware and see the actual value and use for it rather than seeing a pile of scrap with gold retrieval possibilities.

The big differences in the two systems was that the original had a dark plexiglas cover over the controller storage compartment and the controllers were hard wired into the unit. It was the first home video game system to use programmed cartridges, but I think the cool thing about the Channel F was it 4 axis controller. ========================================= Doug Coward Press Start Inc.

Back to the original topic some. History. MS was not the only game in town. DRI, later Novell, now Caldara offered CPM86 and it decendants such as CCPM and DRDOS until MS crushed them. Caldara is still at it with Opendos (DRdos decendant). < Personally, I avoid MS-anything like the plague... I have a linux < system which has been up for more than a week straight... running < W95, I'm lucking if I *don't* have to reboot several times a day < either because the system has simply crashed, or wedged itself... I'm no fan of MS but I run a ton of CADD, FPGA and cross assemblers unavailable for Linux or freeBSD. The system that I must run it on is MSdos6.22/WIN3.1 that generally has an up time of months between reboots. The last down time was for a fan replacement. I've never run w95, but I've seen systems that can achieve that as well. My other half has a laptop for work that seems to be solid enough. None of the MS OSs are great products, they work ok though and when the system is configured with stable hardware and software. I've also found that linix or freeBSD tends to beat the daylights out of hardware and find even minor problems that seem to get by under MSdos/win but cause it to crash intermittently. Most of the complaints I've heard of MS dos/winders can be leveled at Linux or other unice as well. My pet peave is that most of the PC unice are limited about what hardware they run on and like win95 also will not be happy with a minimal 8meg of ram. Now what has this to do with old hardware. Unix has been around for some time, some 25-30 years. It's still not the generalized platform for applications software. I find that good low cost CADD tools are non-existant and most require Xwinders which is a memory hog and yet another potentially cranky item. So until I can find a good CADD, schematic capture, PCB routing, XAble and Xilinx FPGA package for PC unice for under a few hundred $$$ MS wins. That defined the market. Allison

It is not usable on anything but a twinax network. I bellieve that IBM made 3 versions of varieing speeds in two interfaces. The second interface is a BNC Coax for the 3270 systems. While the networks are over 10 yrs old I doubt the printer is. Paxton

Microsci HAVAC

by kaikal＠MICROSOFT.com

This weekend I picked up this wacky little 6502 computer called the Microsci HAVAC. Has anyone else ever seen one of these, or better yet, does anyone have a boot disk for it? The HAVAC has the weirdest floppy drive I've ever seen. It has a center-mounted clamp lever, and the head positioning is done via a spiral-grooved disc! The machine is about 16" deep, 10" wide, 8" tall, with the floppy drive in the center front (there is no door on the drive, just a slot and the funny lever -- no eject mechanism either, just pull the disc out manually). There is a small external keyboard about 10" by 13", no numeric pad, connects via a D-sub connector. On the back of the system unit, there are serial, "printer" (parallel?), 2nd floppy, and RCA video output connectors. I fired it up, and it displayed a HAVAC logo, ROM version 1.3, then the expected "no disk" error. I examined the system board, which is dated 1983, and has a 6502 CPU. There is no info anywhere on the net about this machine, that I can find. Any info appreciated, thanks Kai

I will admit up front that I don't know everything, and I am not an EE (dropped out of community college) but it seems to me that Intel hadn't won anything until ~81 when IBM came out with their PC. Until then, the Z80 and 6502 were as dominant (if not more so) than the 8080/8085? In fact, I'll go so far as to suggest that perhaps if IBM had gone with, say, the z8000, Intel would not be anywhere near as big as it is? It seems to me that what really got the "cheap computer revolution" going was the Z80 (CP/M, TRS-80, etc.) and the 6502 (Atari, Commodore, Apple II). Because no matter what the tech-heads are doing in their garages, nothing is a revolution until you can buy it at Sears. There is a similar situation with digital recording -- it's been around and available for eons, but mostly was only available to those with lots of $$$ (big studios/record companies) or tech-heads. Now, with the soundblaster/CD-R combo and some software (which, if it isn't available as shareware, I would be extremely surprised!) anyone can cut a full-digital (DDD) CD at home. --------------------------------------------------------------------- O- Uncle Roger "There is pleasure pure in being mad roger(a)sinasohn.com that none but madmen know."

I think that the amount of marketing necessary is related to the quality and value of the product itself.

She said, 'Well, their entire PS/2 line was killed off'. For one thing, the PS/2 shows that with great marketing and technology, a product can still fail.

Guys: Are there any of you out there looking for these beasts? I know somebody who's got a 5120 and a 5126. He's asking $50 each (too high in my opinion), but the price ought to be negotiable. I know he also has at least one power brick, and an NOS portable battery charger (M0275). Send me personal e-mail if there is any interest.

It is one of a family of four new ICs which comprize the MCS-4 Micro computer system - the first system to bring you the power and flexibility of a dedicate general-purpose computer at low cost in as few as two dual in-line packages. Seems they were aimed squarely at the low cost market.

We used what we knew about and at 200$US each they weren't cheap at all but it was better than 200 pieces of TTL that had to be wired and tested. So the Mark-8 Etal had the precedence of visible advertizing, Docs and availability. An aside , the docs part was not lost on moto! You could get the 6800 cheap enough and for 25$ more you could get a thick volume of hardware and software knowlege that made using it easy. < What I'm trying to say is that this revolution would have happened with < without Intel, and assigning them all the credit for creating this < industry, or making it possible, or even influencing it is credit not < entirely deserved. What is missed and not mentioned is the small details. INTEL created the 4004 becuase they didn't want another fixed function calculator chip for only one vendor. This ment they could mass make it and sell to everyone with higher profit. The 4004 was significant as it had a hardware return address stack. There are things there that did seperate the micro computers that would result from the minicomputers that were before. < > importance of the 4004.

Also the 4004 was *relatively* cheap but the amortized development cost were still significant and have to be include to be fair. < > 4004 was the Big Bang; that the dust from that explosion still bears t < > Intel imprint is interesting, but that's a different topic. < < And I am still arguing that the 4004 was NOT the big bang.

I'd say there is some reality there. The big bangs were those that would hit the media and cause ripples down the line. Using that line of thought... the CPU chip was not the big bang but the catalyst for the explosion. IE: Altair was not significant due to the 8080 but that it was first of class and more importantly COPIED. Name one other machine/bus before ALTAIR that would be copied widely and competitively within one year of introduction!?! I will add that I doubt Intel saw it as a serious opportunity to sell chips until after the Pop'tronics cover hit the stands. Reason it would be little while before the hobby (we were called that) market would be taken seriously and semiconductor vendors would see the potential of the early edge of the personal computer/ small desktop computer industry. That got DEC, IBM and DGs attention though none were sure of what to make of it. The fact of it was by 1978 there was no question that there wer more microcomputers (or various types) than all of IBM, DEC and DGs output to date! It was the Volkswagons of the computer industry.
