    Never in my life did I think that retro computer kits would be a thing, over 40 years after they were originally released, but I'm glad. I can show my daughter the 8-bit computers I grew up with as she looks at lines of code and at simple looking games (slightly bemused) and yet having played like Space Invaders, she returns to them later on, as she finally understands gaming concepts like playability meaning more than something looking good or sounding good. So far it's all been on emulations so something running on a PC or tablet means it's still attached to today's technology but a board and chips shows how old computers were.
    The beginnings of affordable home computing is a subject today's tech nerds need to delve into to understand it and it's a fusion of generations who enjoyed it long ago and get to enjoy it again.

      I got my first computer in 1995, a variation on the PowerMac 6100. I still wanted a Compact Mac to hang onto and play around with some older stuff from the late 80s/early 90's that wouldn't run on that machine. Never really got into Apple II though. Played around with it a bit, but felt a bit too basic for me and never really had the desire to go back to it.

      It sounds like you're reaching. Hardly anyone grew up with a PET. They just were not ever meant to be in the home for kids. Literally nobody was asking for this computer to be made. Being a PET, it is essentially DOA. They are no good for games and nobody would ever use one today for any kind productivity or even as a terminal to an internet based BBS. It is an expensive piece of kit where the best experience you will have with it is soldering it and then troubleshooting where your mistakes were.

I ordered the one with just 4K of memory ($600) but several weeks later got notified that they weren't making that version anymore because everyone was asking for the extra 4K upgrade which cost another $200!!

    Design it so it can be tested electrically, as much as possible. Tell them to check the power before putting the chips in, etc.

      Indeed. Unwanted shorts between adjacent pins and to ground (particularly of the power rails) are something that can and should be checked during the soldering process.

      @@EvilSandwich BASIC had its place, but these days the most commonly found language in learn to code courses is probably Python - as used, for example, on Raspberry Pi. Those working on embedded systems will typically use C, perhaps using the Arduino or mbed environments initially. The first rudiments of programming are sometimes taught using visual coding environments like Microsoft MakeCode (e.g. on BBC micro:bit hardware).
      BASIC made sense 'back in the day', but suffers from lack of standardisation in areas such as flow control and lexical scoping. Graphics primitives are dialect specific, as are any library or object orientated features. These limitations together with the wealth of pedagogical material already out there for alternatives such as Python means BASIC is unlikely to make a comeback.
      The last company to push BASIC heavily was probably Microsoft with Visual Basic, but traditional Visual Basic was declared a legacy product in 2008 and development stopped with Visual Basic 6.0. Visual Basic .NET is still actively developed, but is a fully object-orientated language that doesn't have the deterministic execution of traditional Visual Basic. C# is perhaps more popular than Visual Basic .NET for .NET development, though the popularity of these two languages seems to wax and wane.
      Realistically, traditional BASIC is a legacy language these days, just as 8 bit microprocessors are legacy products these days. Low end 32 bit microcontrollers are so cheap now that there is little reason not to select a 32 bit chip unless using DIP packages, 5V logic level compatibility, reuse of existing code assets and/or shaving every penny off the BOM cost steers you towards an 8 bit chip.
      I have fond memories of my journey with 8 bit equipment but I haven't powered on my ZX Spectrum or BBC Master in years (and would expect them to need some recapping and other hardware maintenance to use them again). I certainly would not spend the money on something like the Mini PET, wonderful as it undoubtedly is for those who want a 'new' PET. If I wanted a 'new' 8 bit, 16 bit or early 32 bit computer to use for legacy system software, I'd probably go for an FPGA based solution if software emulation was inadequate.
      If you want to buy something to code on, you can buy a Raspberry Pi or similar device for something like a quarter of the cost of the Mini PET kit, power it with a redundant phone charger (so long as it has sufficient output), hook it up to your television using HDMI, connect an inexpensive wireless keyboard and perhaps also a mouse and you have all you need. The Mini PET really isn't a learn to code tool - there is little point in most people learning about the limitations and idiosyncracies of systems originally designed over 40 years ago.

      @@DavidWood2 Not everyone wants to learn programming to make a career out of it. Some people just want to explore and play around for fun. That being the case, a simple to understand language that can teach the rudiments of programming is just as valid as learning some variation of C or Java etc. Modern computers are daunting, huge layers of abstraction, requiring various bloated 'libraries' to access their complicated user interfaces etc. It's easy to be distracted or put off by that, and many modern languages just aren't ideal for learning the very basics. Who cares if the language isn't a modern 'standard'? C, C++, C#, Java, Python, Perl and Lua are all different to each other anyway. However, the basic mental processes are transferrable, so once learned, it relatively easy to move on to another language.

    I haven't read all the comments (there's a 1000+), so just a tip on the placement of the power regulators, and that instead of directly soldering the main tab onto the pcb, it might be more convenient to use heatsink grease & then use a screw & nut to hold it down. This is the usual industry "standard". It is more convenient than soldering especially when you have to replace the reg. That is why the regulator tab has a hole, to use a screw. You can also add a separate tiny heatsink to the tab, either make it yourself from sheet metal with a simple shape, or find a proper heatsink for TO-220 packages. I don't know how hot those get on a PET, I haven't used a PET since the mid 1980's.
    Personally, as for the MiniPET, it would be nice if it was designed to take advantage of the higher speeds of the new 6502 it is using, but apparently it doesn't, I'm unsure, even if it takes carefulness for any compatibilities.

    Popping the spacebar on two switches really isn't a good implementation. The official spec for Cherry spacebar calls for one switch in the centre (though it doesn't have to be dead centre, 6.25u spacebar has a couple different implementations where the centre stem could be slightly offset) and supported on either side by stabilisers that are coupled together using a wire. This will allow the spacebar to depress smoothly even if you press on it off-centre. It's pretty trivial to implement the cutouts for stablisers (you basically just need to have 4 correctly-sized holes, 2 sets on each side of the spacebar for the stabilisers to clip into the PCB.
    Cherry stabs are standard parts, and any decent enthusiast mechanical keyboard store will have them.
    Edit: The keycaps you're using are a cylindrical sculpted profile, which means that the keytop on each row has a different angle. If you want them to be all uniform, try looking into uniform caps such as DSA or XDA profiles, they give you more flexibility to implement oddball layouts (such as what you're trying to do in this video) since every row is uniform.
    Edit: Instead of using stickers, which may peel off over time, you can try getting PBT blank keycaps, and use a thermal print transfer process called 'dye sublimation' to permanently print the label onto the keycaps. This printing method essentially 'infuse' the ink onto the top layer of plastic (PBT is somewhat porous, and heating up the cap before printing allow the pores to open up and let the ink seep onto the surface, which then close up again after cooling, resulting in durable printed legends that will not fade)

      @@The8BitGuy SMD parts certainly can be cheaper than DIP components, but for the price they are asking, the cost of the components should not be the problem. My initial though was that there was about €50 of components on it, but since they are using original WDC parts it might be a bit more. Still, I don't see how you could reach €100 with the components on the board. Whatever the reason of the cost, there should be plenty opportunities to reduce the cost without resorting to SMD.

    Hey Dave!
    As an electronics engineer myself, the assembly of such things is very difficult and the 'short to ground' failure is very common. Usually, I test a new board by checking every power rail if it is shorted to ground and etc.
    Also having a solder frame (which is used in production) helps a lot! I'd love to assemble the commander X16 and give some hints about assembly instructions.

    Generally when building a kit with socketed ICs I first install the power circuitry, power up the board with no other chips and check for proper voltages, then install all of the chips. But, I know you just wanted an excuse to troubleshoot! Very nice kit - I remember the PET in it's heyday but could not afford it as a poor high school kid. The other tool I find handy is the bracket which holds the board for easy flipping when soldering. Got it on Amazon recently is really handy.

    With the keyboard, wouldn't it be possible to do some extra things like actually getting a number row working by "translating" the key-press into a PET output key press with a micro? i mean, you might have to do that anyway with the shift-lock and the moved keys, so wouldn't that be an option? Or is putting yet another micro-controller inside a machine that's less powerful than a micro-controller cheating too much?

    • @digiowl9599
      @digiowl9599 4 роки тому +1

      My thinking as well. It may even be simpler depending on how the board and all is done. After all, he have two blank keys next to the space bar. If possible, one could have those act like a "numlock" and switch the scancode or something between the numpad and the top row. While engaged, the PET would see a numpad signal whenever a top row key was pressed (while also giving you symbols when pressing something over on the numpad). but this is me just brainstorming.

  • @merseyless
    @merseyless 4 роки тому

    Regarding the soldering, you will create a more reliable joint if you feed the solder onto the joint, as the flux core can remove any oxidation on the joint rather than burning away on the iron. I find that having a bit of solder on the tip, pressing it against the pad+leg then feeding solder from the opposite side (or thereabouts) works well. Depends on having a good iron, don't get me started about soldering irons.
    Also, for your connection between the to-220 and the board, grab some flux. Any time you can't feed in flux core solder into the joint, you should use flux. I keep a tube of thick flux and a flux pen on my own bench. Thin flux from a pen would be better for that joint but thick is best for any rework you ever need to do. Invaluable for SMD work.
    For your quick connection between the keyboard and computer, grab some "DuPont cable" (actual name) for next time. That stuff sneaks into all my projects.

    A trick that I was taught in the 70s was to solder in on corner of the chip. Then Use something like a tissue and your finger of the other hand and press and reflow. Check to see if it is in flat. The do the same on the diagonal opposite corner. I did all the sockets. When all are in and flat, I would begin doing the rest of the pins in a group. We did soldering at the time to mil speck. Our inspector looked for pin holes and other defects. This was for prototypes.
