  • The Vintage Computer Appreciation Thread

    Hello, everyone. After some of the responses in this thread, I figured I'd create another thread for discussion of 'vintage' computers. As you may have seen on my website, I've amassed a collection of several dozen, stretching from ~1976 to 1994 or so (not sure what the cutoff would be; most of them are pre-'90s, at the least). Anyway, I'll get the thread started off with a couple of pics of some of the rarer machines I own:

    Apple Lisa 2

    As some may know, the Apple Lisa was Apple's very first computer to be equipped with a graphical user interface. Released in 1983, it retailed for around $10,000, and that combined with a lack of third-party support lead to low sales. When the Macintosh was released a year later, the death knell was sounded for the Lisa, and after attempts to improve sales, several of them ended up being buried in a Utah landfill.

    The story of how I found my Lisa (actually a Lisa 2, modified to act like a Macintosh Plus) is rather unbelievable. I was hanging around in a local computer surplus store looking for memory for an old iMac, when a couple of guys showed up looking to sell some computers to the store. When asked what they had, the guys started rattling off the names of various vintage computers, including Apple IIe, IBM PCjr, and Apple Lisa.

    After being told by store employees that they couldn't buy the computers due to being too old to support, the guys asked if they could just leave them in the parking lot. When informed that at least some of these computers had value to them, the guys replied that they didn't care, they just wanted it all gone. I waited several minutes, then poked my head out of the store. Sure enough, the parking lot was filled with all sorts of computer stuff, including an Apple Lisa 2! I immediately loaded it in my car, along with a few other computers, and got the heck outta Dodge. I went back some time later to get something I'd left behind, I saw some scrappers loading a truck with stuff from the pile. I figure that if I hadn't been there, the Lisa probably would've ended up in a scrapyard........

    Commodore SX-64

    The SX-64 was intended as a 'trans-portable' version of the popular Commodore 64. Released in early 1984 for $995, the SX-64 is considered the first portable computer to be equipped with a color monitor. Of course, "portable" is relative in this case, since the SX-64 weighs around 22lbs (10kg), and needs to be plugged into a wall outlet. The SX-64 was intended for business users who needed to be able to take the computer home with them in order to be able to continue their work. Of course, it wasn't too long before the price of the regular C=64 dropped to the point that a full setup was cheaper than buying a SX-64, and you got a larger monitor to boot (the SX-64's CRT measures a measly 5" diagonal, though it's fairly easy to read for its size). Consequently, not many were sold, and it was discontinued a couple of years later.

    My story about the SX-64 isn't as awesome as with the Lisa, but still kinda neat. I was looking around at my favorite outdoor flea market, when I spotted the SX-64 sitting under a seller's table. Expecting it to be priced in the stratosphere, I was stunned to see that the guy only wanted $20 for it! I quickly forked over the cash, and began the long journey back to my car (made worse by the weight of the SX-64). Other than a few quirks with the floppy disk drive, it works fairly well.

      Well, I once bought an IBM 2311 disk drive at a swap meet. I was overly optimistic about being able to convert it to work with a micro computer.

      It was the size of a washing machine and took these *huge* "disk packs. Only had 5 meg per disk pack.

      I still have the disk packs.

      And in a storage drawer with a bunch of 5.25" floppies, I have a 256 *byte* core plane I picked up at a surplus shop.

      I seem to have misplaced the pic of the entire thing, but here are successively closer images I took with an old Intel QX-3 USB microscope.

        Nothing wrong with that. Some people, of course, just use theirs to display the binary one, in a rather rude format.......

        Speaking of hand computing, I recently picked up a vintage Keuffel & Esser slide rule from the '50s. I have yet to get the hang of using it, but it's an interesting doohickey nevertheless. Of course, what I'd really like to find someday is a Curta........

        (what I do have is an example of the device which is said to have killed the slide rule...)

        You might not have been quite as crazy as you think. Some time ago, there was an attempt to build a modern computer interface for an example of the original IBM RAMAC hard disk drive from 1956. They appear to have succeeded, even!

        Very cool! I have yet to acquire anything which uses core memory, though a fellow computer collector does have a quantity of it. Rather amazing when you think just how much work went into weaving dozens, if not hundreds of those tiny little ferrite donuts together using hair-thin wire! Makes me want to find an HP 9100.........

          I remember the HP9100 from back in HS in the mid 1970's. One of the Math teachers acquired one and was teaching some of his advanced math students (not me but my GF at the time) a bit of programming (Yeah RPN was a bitch I did learn a bit from GF). If memory serves it used little magnetic strips (the size of a mag-strip on the back of a credit card) to either save a program or load a pre-prepared programs.

          Heck even HP pocket calculators in the late 1970's used RPN.

            Very cool! I've heard lots of interesting things about that machine. The 9100 indeed used magnetic cards as part of its program storage (the later HP-65 pocket calculator used smaller magnetic strips for the same purpose). The only HP desktop machine I've acquired thus far is the HP 85A. It's considered HP's first true 'personal computer' (as against a desktop calculator which could be programmed in BASIC, like the 9830 and its ilk).

            Yep, RPN was a fixture of most of HP's pocket calculator line from its inception until the early 1990s or so (they do still offer RPN calculators, but most of their current offerings are algebraic types). The beginning was the HP-35 in 1972, which was based on the same basic engineering as the 9100, though the programmability aspect wasn't added until the HP-65 from a few years later. I've owned several different HP pocket calculators, both LED- and LCD-based. Their "Voyager" series is probably the most celebrated of the latter; the HP-15C is still legendary when it comes to complex equation solving, and the HP-12C financial model is still in production nearly 35 years later! Here's a picture of my HP-11C, which was the mid-range scientific offering from that line:

              I don't see how displaying the binary one would be rude - Fonzie did that routinely (or, counting the other way, he displayed 16 routinely). Displaying the binary 4, on the other hand, is definitely rude.

                    WOOHOO!!!

                    Scored an Atari 1200XL computer, in its original box, at a hamfest this morning for all of $30!

                    For those who don't know (and I wouldn't blame you, really), the 1200XL was Atari's attempt at a follow-up to the 400 and 800 8-bit home computers. While it was in development in the early '80s (as the 1000), Commodore threw Atari (and the rest of the home computer market) into a tizzy when they released the Commodore 64 in 1982. Atari threw together the 1200XL as an attempt to compete, but it received a cold reception due to several factors (including the fact that the C=64 resulted in a 'pricing war' in the home computer markets), and the 1200XL was discontinued after a few months, replaced by the more-successful 600XL and 800XL. I already had an 800 and an 800XL, so I'm happy to have an example of the "missing link" between them.

                        At least part of it was likely that the Lisa was far more expandable than the original Macintosh. The Lisa was equipped with far more memory, and was able to use a hard drive. Methinks you couldn't do a whole lot of software developing on the original 128K Mac...

                        Yeah, "luggables" were fairly popular back then. I used to own a Compaq Portable, and it was an interesting machine, though its power supply had issues trying to run a 'hard card' (or, really, anything beyond the default configuration). I still have a Compaq Portable III, which has a later addition to the series, using an 'advanced' gas-plasma display in glorious orange.

                        Last year, I picked up an example of what could be considered the "modern" version of a luggable, made by a now-defunct company called Dolch. It's similar to the Compaq Portable III, but is equipped with a then-advanced Pentium processor, and a full-color LCD screen. Apparently, the luggable design stayed popular in industrial markets long after they fell out of favor with consumers...

                            Yeah, the IIc is a cool little computer. When I was in elementary school, a IIc was probably the first computer I came across which didn't look like a standard Apple II/e (which was what we had at home at the time). It was in the computer lab, paired with the matching monochrome monitor, which I thought made it even cooler. Unfortunately, it disappeared shortly afterwards, so I moved to one of the lab's regular Apple IIe Platinums, though I used the teacher's IIgs whenever I could manage to...

                            Fun fact: Apple also produced a IIc Plus. It had a faster processor than the standard IIc, and was equipped with a 3.5" disk drive instead of the 5.25" one used by the IIc. It was introduced after the IIgs, and was technically the last new model in the once-proud Apple II line, which was soon abandoned in favor of the Mac.

                            When I was in high school, the storage area of the electronics shop had both a regular IIc and a IIc Plus. Shortly before I graduated, I was given a choice of which I could have, and I picked the regular IIc, since I knew more about it. Oh, if only I'd been allowed to take both of them..........

                              ZOMG! The "friendly orange glow"... One of the first computers I really spent any serious time on was the PLATO system, which used orange plasma panels. http://www.cyber1.org/

                              Hugely advanced, for the time, they had 512x512 individually addressable pixels, and an 8x8 IR touch-screen, as well as a keyboard with a bunch of keys we don't have nowadays. ("STOP", "DATA", "TERM", etc.)
