I scrounged around a found a stock of Intel 1702 EPROMs today. I know some of you have been looking for these. What are they worth? Joe

Is video relevant? (was: The "FIRST PC" and personal timelines (Was:And what were the 80s

I have to agree that the argument is not pivotin around a single point. I've always thought of computers intended for home use as being personal computers. This doesn't mean that they can't be applied to non-home tasks, but if they're designed, packaged, and marketed for home use, they probably ought to be considered personal. The same can be true if they were designed to be used by a single individual, as opposed to several even if at different times. This doesn't mean that if it can be used by more than one individual it's not a personal computer. Likewise, if it's priced such that a normal, rational (not to imply that we users are either of these things) person could easily consider and justify owning one, it's probably a personal computer. Whether it had video-game-capable graphics is another issue. NOT EVERYONE WANTS HIS COMPUTER TO BE A HOT GAME MACHINE. That doesn't say that everyone who has a computer well suited for video games has a game machine, but it also doesn't say that every "game machine," be it Atari or Z-whatever, must be excluded from consideration as a personal computer. Frankly, I've completely lost track of why this was being discussed. I was, at one point indicating that what was listed at the "first" personal computer was really pretty expensive for "personal" consumption at the time at which it, or, rather, its plans were being marketed.

I have to agree with you on this one. The business community lent some measure of legitimacy to the "pre-IBM-PC" systems by putting them on the desktop to do "useful" work. They didn't care so much about "Space Invaders" or some other game. Without Visicalc and Wordstar, the micromputers of yesteryear would have been nothing more than video toys.

Don't forget that between 1952 and 1960, the price of a phone call, a coin-machine-vended soft drink, and lots of other common consumables doubled. The price of cars did more than that, and the country, having endured, and survived, the post-war(s) recession(s), was about to embark on what now is viewed as the biggest and fastest moving era of economic growth the world has ever seen. That took less than the 8 years between the end of the Korean war and the election of JFK.

That's actually true, I believe, although the now-past concentration of "intelligencia" in CA was the product of wise investment in educational institutions on California's part. With the economic successes bred by the liberal policies toward education and human services, California became a magnet for not only free-thinkers, but free-loaders as well. Now they're well into a backlash, e.g. Prop 13, Prop 187, etc. which seem to have passed. The liberal forces are still strong though. They talked about Jerry Brown as "Governor Moonbeam" but he was just a reflection of what the people had indicated a few years earlier that they wanted.

H214 board for pdp-8x?

Can any pdp8'ers out there tell me if an H214 core board works in an 8E ? I thought the 8E used H212, but I'm not sure Thanks! Jay West

I was not trying to mislead anyone, but, rather, to pass along what my colleagues and I were told at a pitch put on for us by the DEC sales force. We were engaged in a militarization of a uVAX-II by repackaging it in our own enclosure, with our own backplane/cardcage, and using EMULEX controllers and a truly high-res display subsystem separate from the console. Our task was integration-intensive. We had to buy a company in CA in order to ensure they would be around long enough to produce our ultra-high-res display boards, though I would have preferred to build it ourselves. That notion was incompatible with the premise on which the contract was based (COTS equipment, repackged to meet TEMPEST, among other standards. Do you suppose DEC had a separate company for handling this type of contract? That would explain the party-line that was laid out before us. We bought their Q-bus boards but provided our own <virtually everything else>. It seemed reasonable enough that they would take the position they took with government/military business. >DEC sold stuff via OEM's who often did system integration with NON-DEC >hardware and software and packaged systems with specialized requirements. >I remember a Martin Marietta special 11/70 in tempest cabinets with special >requirements -- but that was not common. > >A large number of the DEC stuff was sold through government contractors >because they could get machines under blanket agreements without >some of the government procurement restrictions and approvals. That was probably the case with our particular contract. I wasn't involved in the procurement, which made it a curious thing that I was sent to all these pitches. This was a "cost-plus" contract, so naturally it benefitted everyone when we could make the cost go up. Subsequent fixed-price arrangements had me begging our top managers to let me redesign the whole computer/cardcage/backplane using the microVax chipset by then (9/86 or so) available for use in BI-bus interfaces, on a VME card. I believed I could cram all the required hardware onto a dual-height VME card (about the size of a full Q-bus card) so we didn't have to deal with so many vendors, and then allowing us to use more readily available hi-res graphics hardware. The situation was so politically charged, I was called on the carpet by the VP in charge of that contract, and, I believe, nearly fired. If I hadn't been so fortunate as to have a long string of technical predictions (contradicting what the JPL guys had said) which were substantiated, I probably would have gone packing that day. >DEC got sued (and settled with the govt) because of the following issue: > >GSA got higher pricing from DEC than Ma Bell on their Vax orders.

You're right, the numbers are not universal. It's hard to find numbers that are, BUT, in 1952, people didn't have electric dryers, and washing machines had wringers attached, as well as rollers on the bottom because housewives would roll them out the walk in back of the house to where the clothes line was located so they could hang their clothes and linens, the latter having been wrung before being hung on the line. In '52, as men were returning from the Korean war, the economy was still shuddering from the effect of the Korean war so soon in the wake of WWII. I'm not an economist, and even they probably can't explain exactly what was going on, but in the early '50's a phone call, a soft drink, a Saturday movie, and bus fare typically cost a nickel (that's 5-cents for those not accustomed to our monetary units.) in the midwestern US. In early '52, I lived in NYC, having just immigrated from Germany, and later (June '52) in Oklahoma City. In '55, we moved to Denver, where things really didn't seem too different, at least from what I heard from parents, etc. By then some people did have electric dryers, though. Electric ranges were more common as well. Housing was typically on 1/4-acre lots in the suburbs and the usual 1/6-1/5 acre lots in the city. If you lived where lots were 1/3 acre, you were probably well-off. When I lived in Oklahoma City, my nearest playmate was a physician's son. The guy who lived across the street from him was the chief of the state's highway patrol. By 1960, the culture had changed so much that people in those positions wouldn't dream of living in the same neighborhood with "working folks" like my parents. What I'm getting at here, is that things were VERY different by 1960, than they had been seven or eight years before. If you were raised after '60, the world would have looked quite different than it did in the early '50's.
