    The PET is completely original and it never had a banner display. All that stuff was stored in my workshop for over 20 years. I'd decided all that stuff needed a new home and I couldn't think of a better person to take care of it than Adrian. It was a pleasure to meet you and give everything a good home.

    Fun project! Really looking forward to watching this machine come back to its former glory. The PET has a special place in my heart because it was the first computer I ever used, and it really got me started on the path to an eventual career in tech. When I was young my parents would send me to summer camp, every year, without fail. I. HATED. IT. WITH. A. BURNING. PASSION. I'm NOT what you would call an "outdoors type." Well somehow one of the camp counselors must have gotten wind that I was into electronics, video games, etc. (maybe they heard me talking with someone or something) and they made a deal with me: if I participated in the day's activities, in good faith, as best I could, then during the evenings they would let me play with the computer in the camp office. Which happened to be one of these exact model of PET. (I remember that wonky keyboard well.) I would happily while away the evenings playing games loaded from cassette tape and generally messing around with it, and eventually I taught myself BASIC and started writing my own games and other programs. The rest, as they say, is history.

    Amazing how far technology has come since the 1970s. The very first computer I got to see was in fact a PET 2001 sometime in 1978. The first one I got to actually use was an Apple II around 1983, then I got a 64 for Christmas in 1984...

Plus you have to credit Commodore with their foresight in bringing to market what amounts to the first plug&play "appliance" computer with everything built-in. Granted, neither the datasette nor the "keyboard" were anything to write home about, even back in '77. 😫

    Oh my God I owned a Commodore pet 2001 which I Purchased from Rick Inatone Back in November 1978. I programmed that computer day and night, I peaked and poked the memory. I can remember typing Hexadecimal code into the machine to program a chess game. I wrote basic computer software programs and actually stored them on cassette tape. It took 20 minutes to back up the 8K of memory and you had to do that three times just to make sure one of the copies was readable. My first big endeavor was to program a bowling league sheet which I printed on the commodore dotmatrix printer. I eventually programmed my business using Commodore 8032’s coupled with the hard disk drives, what fond memories. I actually have video tape of me playing chess on the computer with my son on my lap, as he was only less than one years old. Thank you for bringing back such memories.

    on March 14 1978 I got an 8k PET 2001 for £695 and it started me off on the road to computing. I added a 32K memory expansion and a second cassette deck.I helped start a company called Petsoft that year and wrote programs for it. I gave up my job and went self employed for 4 years earning a living from the PET. I had a great time.

    The PET was what I used in high school until we moved "up" to a T!99-4A. I repaired a crack in one of the copper traces on the motherboard and it performed flawlessly. Somehow one of those green capacitors had gotten whacked and it broke the copper track. There was enough lead left to solder it back together. The thing had been gathering dust in a library for who knows how long.

      @@douro20 One of my former employers used a 3000 series PET for instrumentation and data acquisition in their research lab -- specifically because of the GPIB. It actually was the lab's first computer when it was founded in '79. The PET was last used as part of a "multicamera optical system" before gathering dust in the lab's basement. That PET is now in my possession, and still doing well. (Ok, the monitor's horizontal linearity is a bit out of whack; probably needs a new cap in the deflection).

    Went to Secondary School ( ages 11 - 16 ) here in the UK from 1978-1983.
    For most of that time we had a single Pet 2001-8 , in a school of over 1200 kids!!!
    In fact most of my o-level course work was done on this solitary Pet ( or by sending a hand written listing to the local University where they transferred it onto Punch cards to be used on the Main Frame !!! )
    Used to bribe the caretaker to let us stay after hours so we could use it.
    Hours & hours in typing in programs from various magazines & books when I was supposed to be doing Computer Science coursework .
    Even more hours spent playing - 2 games stand out in my middle aged memory - Star Trek & Nightmare Park
    Would really love to be able to find one & give it a good home

    That was the first PET I used in high school at the BTHS Physics Dept. Computer club in '78 and then we got the other 2001 with the full keyboard. Strange; the newer 2001s with the large keyboard used 2114s Static RAM Chips and 4108/4116 Dynamic RAM chips. Putting/upgrading that PET with more RAM should not be a problem.
    Later in HS ('80/'81), the Math Dept. got a bunch of 4016s to teach programming on but being a computer club member, I was head of the class and the teacher who did not know anything about programming.

    On old dusty computers like this with dual row ICs, I'd recommend carefully pulling the socketed ICs and cleaning the contacts manually. Use a glass scratch brush on the IC pins, and a small contact file in the sockets if absolutely necessary, after a good swipe with alcohol and a toothbrush as the first course of treatment. De-Oxit is good stuff, but it helps to get things as clean as possible first before using it around PCBs, because it will tend to wash the contaminants onto other parts of the board where they can cause issues. Honestly though, I'd probably ultrasonic the whole board too, and replace all the electrolytics as a matter of course. It doesn't seem that much is wrong with that PET other than some poor contact surfaces and/or dust bridging lines.

The only models that used the MOS 6550 SRAM chips were the 2001-4 and 2001-8 (sometimes called the 2001C machines to differentiate them from the 2001N and 2001B models).

    the expansion port carries a full bus up to address line 11 along with quite a few pre-decoded select signals and as such... yes. you can hook up pretty much anything you want to it and i'm sure people did and many still do (mainly considering that the thing lacks both rs232 and any other sort of network capability - the pets don't even do software bitbanging rs232 on the userport. at least not without loading the routines for it yourself. so yeah i do guess quite a few people instantly soldered a 6850 to that ;) besides that. other than the keyboard, the basic revision they originally shipped with (most have been modified to basic 4 anyway), some other obvious things. it's pretty much the same machine as a 4016/32 or 8016/32 they all seem to have the video ram in the same spot, 1 via and 2 pias, in the same spots too. they also all have $0401 as the load address, so it's not like the 2001 is gonna do anything more or less than your other pet :P other than having a bit less ram and a worse keyboard :P the only thing potentially causing incompatibilities between the pet series is the various different keyboard versions when decoding them directly... some differences in the character roms for 'international' versions, and the 'basic 2 or 4' (along with different kernal and editor roms to accomodate that) thing. (not that it seems to make much of a difference while running programs as basic 4 is just microsoft basic too. just with another number ;) as for the 'just soldering stuff to that expansion port' eh yeah well gotta keep in mind the previous model was the kim-1 :P lol. and other such things which come with a piece of prototyping board to solder onto on board of all things :P i do think many people 'added some stuff' but no. not with a connector and a cartridge housing around it. :P lol.

    At about 10:30 he frets about using a 1.5A fuse ("it's pretty beefy" and "more than enough for this computer") right next to the label that says the PET draws 1.1A. That could hardly be a better match - if anything a slightly larger fuse would be ideal.

  • @aitchpea6011
    @aitchpea6011 5 років тому +1

    IIRC the side expansion port is the system bus, and could conceivably be used for memory expansion, though I don't know if anyone actually went that route as fitting an internal memory expansion was a trivial matter.

    The big blue Mallory CGS series cap went leaky in my 2001. Last time I took it for a spin, the transformer hummed like crazy and clearly wasn't happy, so I immediately pulled the plug before blowing the primary. The Mallory is originally 27000µF, which is an odd value (it's also a LOT bigger than the one in this video). The closest replacement I found is a 24000µF KEMET, which is much smaller; not sure if it's still long enough for the original mounts. Given that the tolerance is probably 20%, I expect 24000µF is still ok. Mouser and Digikey still list the Mallory CGS series in Europe, but they cost about triple compared to the KEMETs, plus double for shipping!
    Also, the fuseholder on my 2001 broke too, though it was actually the plastic post that cracked and separated where it passes through the case, exposing the metal contact and shorting it to the case! This happened while I removed the fuse to check it (assuming it had blown due to the essentially shorted cap). Luckily these are easy to replace, though the 6.3mm fuses are less common in Europe. The original fuse -- rated "3/4" at 250V, so presumably 0.75A -- is still intact, so that's good news.

      P.S. The top half of my 2001 is actually RIVETED to the back hinge, so removing it isn't an option. I wonder if this is the case (pardon the pun) with all later PETs.

    Great video! The very first computer I ever used was a PET-2001 that looked exactly like that! I was 11 or 12 at the time. I now own a slightly newer model: an early 4016 with a keyboard that's like your 4016 but a small screen like your PET. Mine has a plastic case and a motherboard that was made in 1981: It has dynamic RAM chips like your 4016 but it doesn't have the 6545 CRT controller. By the way I recommend visiting tynemouthsoftware.co.uk for some products that can help you fix pretty much any problem on your PET: They have a diagnostic card and a RAM/ROM replacement card; those just sit between your 6502 and the motherboard and simulate part of the hardware to the CPU. That way you can also upgrade your BASIC ROM to version 2.0 (or later); looks like you have a BASIC 1.0. And you'll have 32K of RAM.
    Some minor corrections. Don't take these personal, I'm just trying to help:
    3:20 Commodore also made office furniture so the easiest way for them to make this was to make it like a filing cabinet.
    3:36 That's an IEEE-488 port. Not specifically for disk drives; it was also used for printers and could potentially be used for other gear such as oscilloscopes or logic analyzers. In the earliest PETs the port didn't work because there were bugs in the ROM. When they released ROM version 2.0 those problems were fixed. My school had an 8050 disk drive that could fit a whopping MEGABYTE on Double Density floppy. It took IBM another 3 or 4 years before they could do that with the PC and the Commodore 1541 was a big step back.
    3:51 That fuse holder was completely gone, it probably got hit from the side when someone moved the machine or put something heavy down right behind it.
    4:23 I don't think I've ever seen anything that used the expansion port on the side but there were plugin boards that used the INTERNAL expansion connector. For example the SuperPET used it to add extra RAM and an alternative processor.
    4:56 You should have shown the underside of that cassette recorder :-) These early cassette recorders had a corner cut off where the batteries and speaker used to be, if I remember correctly. Around 8:55 you can sort-of see why they did that: it would get in the way of the heat sink :-)
    5:14 I think the number is 320008 (not 32008). That's the first circuit board that Commodore made for the PET. Your 4016 is very different!
    7:45 I would recommend against plugging anything in if the fuse socket is as broken as yours!
    10:29 The fuse is a little on the high side (1.5A instead of 1.1A). You just voided your warranty haha :-) . But seriously: "Beefy" and "more than enough" are not the right words. Basically the fuse is intended to be the LEAST "beefy" part in a circuit so that when you get a short circuit, it fails before something else does (such as the transformer). You're probably okay in this case but... read the sticker on the back.
    11:21 The screen full of Q's that goes away means that there's probably a problem in the display character encoder circuitry (probably not the RAM or you'd see garbled data that wouldn't go away). A 'Q' is encoded as binary 00010000 and space is encoded as binary 00000000 in PETSCII. Chances are that it'll go away when you re-seat the chips, especially the character generator ROM and video RAM.
    12:33 Looks like your system RAM is not fully working either: That should say 7167 bytes free.
    12:36 If none of the keys are working, it probably means one of the PIA chips isn't working. It's a common problem. Try swapping the two 6520 PIA chips (the other one is used for the IEEE-488 port). Also, again, it could just be that a chip needs to be reseated; those IC sockets are notorious for lousy contacts.
    13:05 This keyboard doesn't use rubber but you may have some oxidization in the switch contacts. But as I said, if no key works at all, it's probably the 6520 or its socket.
    Good luck! Looking forward to the next in the series. That picture of the entire haul looks very promising.
    PS Drive safely! Pictures of mountains and baggage can wait until you're stopped.

    Very cool, I started my voyage into the cyber world with a C=128 and along the way have owned several other commodores from the VIC20 Plus4 and a few 64's even one 64SX that I used as my PC when I ran a PD many years ago. They were great machines in their day, I do miss the always boot of those old machines unlike the trash that we get from China now days

    People think if a PET is at the side of the road it’s been abandoned, but its mother is likely keeping watch nearby.
