Re:About dang time...
I don't remember laughing at the idea of a personal computer costing less than $1000. I remember the early 1980s, when $200-$600 was the norm for a roughly-current-tech personal computer.
I think you're comparing what was then a toy or curio with today's "serious" computers meant to do real work. What was available in the early 80s? Well, there was the Apple II. One of those would set you back $1300--for the cheapest model, with 4K of RAM(http://oldcomputers.net/pet2001.html). For its day, that was a serious computer...and for 1977, that was a serious price. True, you could pick up a Commodore PET for a mere $800 (http://oldcomputers.net/pet2001.html)...but that was a pretty lame machine. If you're thinking of the Vic 20 or the later Commodore 64, or the various offerings by Atari, those weren't really comparable to a "serious" computer of today. They were fun, but not serious computers. My first personal computer was a Compaq "transportable" PC. It had 256K of RAM, 2 floppy drives (the "small" 5" sized ones)...and no hard drive. The screen was a grayscale monochrome about 5" diagonal. It was the size and weight of a sewing machine.
I paid $1800 for the Compaq. In 80s money, that's quite a chunk. I told my wife I needed it for "business"...but really I just wanted to play Zork, and teach myself to progam in C. (Now there's a memory: I put the Lattice C compiler on one floppy, the code and editor on another, the linker and object code on a third, and compiled on a 128K RAM "disk" that I had split off from the 256K total RAM I had available. I felt like a juggler, swapping those floppies...but I cheated by usually holding one in my teeth. I also had to run in place in hip deep snow the whole time.)
The point is that the price for "serious" machines has remained fairly steady, or declined moderately from the mid-80s, but it still costs what—to most of us—is real money to get one. (The price for gaming rigs, on the other hand, has skyrocketed.) But it's also true that some people spend too much money on laptops. If you're one of those "road warriors" who has to work spreadsheets, PhotoShop, or give live demos of bloatware, you need a $2K laptop. But if all you want is connectivity, then the $200 laptop is all you need. I don't think Sony has anything to worry about...some buyers, like parents who used to spend $1K on laptops for their kids will get the cheap ones instead. But there will still be plenty of buyers for the workhorse, expensive laptop. These cheap laptops don't replace full-featured ones. We're just seeing the creation of a new, needed, market niche: the cheap laptop for people who don't need the features and power of the expensive ones.

Re:100% of the PC-compatible business computer mar
They were, extensively, until the IBM 5150 started making serious market share inroads. (Of course, it's true that more "serious businesses" ran CP/M systems, and that's the market the IBM system ate up. But there were business TRS-80s as well as "home PC" TRS-80s used in businesses.
And let's face it, it's a bit disingenuous to say had "IBM had 100% of the PC-compatible market" when there was only one system compatible with the 5150 in the world at the time and it was the 5150. That stage lasted only about a year.

Re:C64 - 3rd PC - Most loved.we got to feel smug despite the rubber keyboard You are being overly generous. The first sinclairs had a membrane keyboard. I also know of many a man that lusted after the 16K expansion module. That's what made the C64 so great. It came with a real keyboard, and a full 64K of address space that an 8 bit cpu could address. Truly visionary.

Next up:
the Lisa II
sorry, already done. The Lisa II (or Lisa 2 or Mac XL) was the follow on to the original Lisa. It replaced the Lisa's dual 5.25-inch "Twiggy" floppies with a single 400KB 3.5-inch floppy and came bundled with a Macintosh emulation program (MacWorks XL: basically Mac ROM code adapted to run on the Lisa hardware). It was released around the same time as the original Mac and cost slightly more, but had a larger display, hard disk drive, expandable memory (up to 2MB) and an internal I/O expansion bus. The processor was slower (6MHz for the Lisa vs. 8MHz for the Macintosh) but there was a custom memory protection/memory management chip that was, unfortunately, never used in Macintosh mode.

Re:Apple II, TRS-80, and Commodore Pet
Claim 3 is wrong..
LOL. Claim is indisputably correct and the fact that you don't know this leads me to believe you weren't even born when the Apple II was released. Not only could one program the Apple II in machine language, but Woz built a debugger and disassembler into the ROM to make it easier to do so.
The TRS-80 was limited ito 4K and 8K DRAM configurations, and the Apple II could be expanded to 48K DRAM on the motherboard and even more via the expandable slots (which the TRS-80 and PET lacked).
And the only "real-world" application that mattered was VisiCalc which was only available for the Apple II.
Clearly you hate today's Apple, but don't confuse Woz's groundbreaking machine with today's company. -
Off-topic - 8088-2 board
That doesn't look like a PCjr board to me, by the way.
The PCjr had various nonstandard connectors on the back. Also there were two slots on the board itself, for the optional 64K upgrade and the optional disk drive controller. Finally there was another large connector on the one side for the sidecar (I'm not sure if that connector was physically on the motherboard or not - it may have been a ribbon cable to the side - but obviously there was some connection for the sidecars on the motherboard).

Re:Your problem is caused by the "keyword" systemNote that the US version had 2k, not 1k. I know, I said that myself:- they could have added more RAM to the US ZX81 (it originally came with 2K) Anyway, I don't see why a membrane keyboard is significantly cheaper to manufacture than a "chicklet" keyboard. Maybe the printing is simpler? How much diff does it make? I'm not an expert in manufacturing, but since you ask I'll guess. Remember that dirt-cheap Chinese manufacturing wasn't around then. Most of the ZX81s- at least those meant for its original UK market- were made in the UK (actually, most of them were made at a plant in my home town, along with the early Spectrums). Although the rubber keyboard itself wouldn't have cost too much, there would also have been extra labour and Quality Control costs. My gut reaction is that it still wouldn't have cost that much more, but Atari released the Atari 400 with a touch-sensitive keyboard too, and that was a far more expensive machine. (OTOH, it could have been said that Atari were emphasising the difference between the 400 and the more expensive 800 with its real keyboard and increased expandability).
One other issue with the ZX81 is that it originally came in the choice of kit or ready-built; though I don't see that a rubber keyboard would be harder to assemble (the one in the Spectrum was really just an all-in-one rubber moulding that sat on top of a ZX81-style membrane keyboard below, and poked through holes in the case above).
Anyway, I had originally assumed that what you had wanted was a real "push button" keyboard, which certainly would have been expensive.
FWIW, they actually did release a version of the ZX81 in a Spectrum-type case with "real" rubber keyboard, with 16K built in; it was called the TS-1500. Unfortunately, I think it flopped; which might prove my arguments against your "improved ZX81" proposal. Or- just as likely- it was because it wasn't released until 1983, at which stage it probably didn't look that attractive on the US market. My 8k suggestion was not so much about price, but more about getting rid of the wiggle-zap problem The rampack wobble (AKA "wiggle-zap"... nice description, ha ha :-)) was down to crap design/engineering. Other companies released rampacks that didn't wobble, and there was no reason that Sinclair couldn't have. When word spreads you are a joke, your company is forever tainted. To be fair, the ZX81s in the UK had the same problem, and they still sold like hotcakes. And then the Spectrum sold like hotcakes stuffed with £1000 notes; there were actually shortages and delays, and it went on to become the UK's best-selling 8-bit microcomputer by far. I think that the problem is that the US market had different economics and different expectations. -
Re:Yeah, but...
Nutria already gave some examples, but I've got more for you.
Tandy 1000, HP's 95LX (and 200LX) palmtop PC with DOS (the 200 had MS-DOS 5.0), the HP 1000CX DOS palmtop, some of the early IBM Aptivas, the HP model 110 line of desktops, the rather famous GRiDLite (my GRiD laptops all loaded DOS from hardrive -- always wanted a GRiDLite too though), the IBM EduQuest Model 30 and Model 40 (I have a few model 40s, but only one still boots -- into OS/2 Warp because I'm not using the on-chip DOS), the Sharp PC-5000 portable, the IBM PCJr, certain IBM PS/1 machines, the Tandy 2500 XL, and some others.
Also, Franklin, Commodore, TI, and Atari had systems with some form of OS in the ROM. Some Franklin systems had something called F-DOS in ROM which I think was mostly a ripoff of AppleDOS.
Notice that these examples are not modern hacks to try it out at home, but all commercially shipped systems from the late 1970s to early 1990s.
AMD and Intel still have documentation on DOS in ROM for embedded systems on their websites, and AMD even recommends Datalight's solution. -

Computer and display
Now wait. You're probably all thinking "What's so cool about that? Just go to Fry's/MicroCenter/your favorite electronics dealer, buy a motherboard, case, power supply, components, etc. and you're done." That's not what I'm talking about.
I'm talking about building an IMSAI 8080. The processor was a 2 MHz Intel 8080A 8-bit processor. RAM? You had to build a separate S-100 bus card using 1Kx1 chips to have RAM in the computer. Power supply? Here are a bunch of capacitors, diodes, resistors, a circuit diagram and a printed circuit board. Go nuts. Hope you're good with a soldering iron.
I spent several weeks putting one of these together in 1976. Once I had it together and working, well, you needed something to get your results on other than the LED panel, so I built a Lear Siegler ADM-3A video terminal. Again, the logic board was a big printed circuit board and you had a couple hundred chips, resistors, diodes and capacitors that you had to solder on it. I used that terminal all throughout college to connect to Boston University's time sharing system.

bus evolution
I think the problem may have to do with the fundamental concept of a computer being an exposed motherboard with a series of slots that house exposed cards. This goes all the way back 30 years to the first micro bus standard (S-100) through most subsequent computers.

This is indeed a practical and economical solution to the idea of putting together and updating your computer. It's really a holdover from the hobbyist days and people have gotten used to it, but it's not really consumer-friendly.
The cartridge approach as used with videogame consoles is better.
I think Atari had the right idea with how it implemented expansion on the 800.
http://oldcomputers.net/pics/cartports3.JPG
The only exposed surfaces were the card edges and the slot. Then you just close the lid.
You see this kind of design approach applied currently to flash memory. If you follow the evolution of the MMC card up through SD and into MINI SD and MICRO SD adapters, imagine the same approach taken with bus specifications. Older cards could be used with newer bus specifications via adapter sleeves. But you'd standardize on a singular form-factor. When you open up your PC, all of the guts would be hidden behind the casing except for the mating surfaces for the cards. All cards would be enclosed.
I don't see this happening because computer technology is by definition transient, disposeable. So nobody wastes money on ergonomics like this. Bus standards change so frequently that you can't even keep your motherboard that long anymore let alone your cards. So you might not even swap cards that much for the lifecycle of the PC beyond the initial system setup.
What I'd really like to see is more effort spent on coming up with a universal backplane that would be more future-proof, maybe something more passive where the glue that binds everything together was itself a module you could swap out. That way maybe the underlying frame could last much longer before becoming obsolete. -
Re:99er MagazineI too am perplexed by their decision to ignore the TI-99/4a. It was cheap enough for just about any family to afford and supported both BASIC (for the kids) and assembler(for the dad). My dad wrote the code and I spent hours designing sprite graphics and translating sheet music into sound() funcs for use in a Frogger game (Toader). We sold enough tapes of that game to just about pay for a 32K memory upgrade cartridge.
Another great one that is missing is the Timex/Sinclar 1000, a $99 machine with 1k of RAM. -

It wasn't mine but an IMSAI 8080
When I was in 8th grade, my school had an IMSAI 8080 http://oldcomputers.net/imsai8080.html that had 8K of RAM, ran BASIC, and had 2 TTY's with paper tape punch/readers. When it crashed, the teacher had to reload the OS with a paper tape that took about 30-45 mins to load.
Then, in high school, we had an Interdata something or other. It had 36K, 2 8.5 inch floppy drives, 7 TTY's and 3 CRTs, ran BASIC and had a Centronix dot matrix printer, and man, that printer was fast. The TTY's had paper tape punch/readers, so you could punch your program and take it home with you! To boot the Interdata, you had to enter a series of codes into an octal keypad on the front panel, the last of which caused the read/write head to move into position on the floppy drive, with a loud clunk. I always that that was really cool!
The first computer I actually owned was an ATARI 800XL that when you entered "print SQRT(4)," it said 1.9. I don't recall the exact details, but it was some goofy bug in the built-in BASIC. In those days, there were magazines that had programs in them that you entered into your computer by keying thousands of (decimal) machine codes into some little BASIC program. I keyed in a word processing program that worked pretty darn well--it got me through my first college career--for the cost of a $2.00 magazine. -

RadioShack Pocket Computer (PC-1)My first computer was a PC-1. I got it for my high school graduation. It came in very handy for any problems that required inverting a matrix or doing a least squares fit. (I can't imagine how people did that stuff with a pocket calculator or a slide rule.)
A set of four hearing aid batteries powered the damn thing for about 5 years. How long do your PDA's batteries last?
Of course I had been writing programs for years before I saw my first computer. I taught myself BASIC about 2 years before I sat down at a computer keyboard. That computer was a TRS-80 Model 1 with level 1 BASIC. Then again, I taught myself FORTRAN about 7 years before I got to use a computer with a FORTRAN compiler (a VAX 11/730).
