My commodore 16 stopped working in about 1988 so I chucked it. I remember all the cheap games were really good and the expensive one crap.

Good job JB. Back in 1988 when I was stationed on Okinawa as a US Marine, I bought a Commodore to pass the time. I managed to get quite a collection of them because all the Marine that were going back home gave me their commodores and manuals. I still have my collection in the closet, together with my Apple IIE from 1984.

I got a Commodore 16 for Christmas in 1984. I still love this machine, the colour pallete and Basic was far better than the Commodore 64. It also had a built in reset and you could access the machine code monitor easily just by holding down the Commodore key and reset. Still looks cool. Coders like Udo Gertz produced games that were amazing feats of programming for the 264 series machines.

It had some very nice features and was a nice machine. It's too bad they removed hardware sprites and a chip that can compete with the infamous SID. This computer was originally supposed to sell for around $50 too! Still, I've seen some demos done for it that are really impressive.

Not bad, I use to make crummy Dupont Cables for a few months until I was shown the correct way. A tip for making Dupont Cables. Use a small pair of needle nose pliers to roll the back end of the pins around the sheathing of the wire then crimp it. Typically if I do bogged wiring good old 30 gauge wire wrap wire works very well and some times if there is space you can run the Wires under ICs and such to keep it neat and secured. Also you can Wire Wrap the wire to Headers and even on parts that have square shape legs.

Bill Herd, original Commodore engineer, has talked extensively about how marketing started to micromanage the late 8-bit projects and ruined almost all of them. The C16 was originally supposed to sell for $49.99 to compete head-to-head with the Sinclair Spectrum, but instead Commodore put the price at around the same as the C64 (with some major things missing, such as hardware sprites or the infamous SID chip!) Commodore upper management would later mismanage the Amiga into oblivion as well. This is why Tesla is so great: The lead engineer also runs the company!

Thanks for the video. I bought a non-working C16 and once I got it working I used this video as a guide for the RAM upgrade and it seemed to work fine. I wonder if you have been able to test this upgraded machine with any of the modern games such as Pets Rescue or Slipstream? Although my C16 shows the expanded RAM at boot, it still hangs on larger games and never finishes loading. The CPU and TED are both original and tested working in a Plus/4 so I can't imagine what the problem could be.

Hey Jan, couldn't you just pop a single connector on the other end of the wires and plug them straight onto the IC legs? No soldering necessary.

@olavl8827 4 жыл бұрын

Not Jan, but I think I know the answer. The female connectors shown in the video won't match the IC pins, they are too big for them so there will be no electrical connection. I'm not even sure if female wire connectors exist that can be used on IC pins. Either way I find that soldering is usually much easier and faster then having to dig out the crimping tool for a job like this.

@@olavl8827 You can cut up a DIP socket (or a SIP socket) into individual pins and do it that way. You usually lose about half the pins doing this. However, the connection will be unreliable if it is just hanging out in the air like this. Soldering as Jan did is the better way to go.

This mod basically turns it into a Plus/4, not a C=64, only without the user port and built in ROM software featured on the Plus/4. The 264 series (C16, 116, and Plus/4) are only compatible with each other and were intended to be a low cost machine to take the spot of the VIC-20 in the product line as a low cost, entry level computer. The main advantages are faster CPU at 1.76MHz, much better BASIC, and the TED (replaces both the SID and VIC) which supports 128 colours, but the drawback is it doesn't have sprites and the audio is much less capable than the SID. www.commodore.ca/commodore-products/commodore-264-plus4-ted-series-the-beginning-of-the-end/

The order of the address (or data) bus wires doesn't really matter. Software doesn't care where the bytes physically are, if they can be read from the same memory address where they were written. The only difference would be if one of the A14/A15 wires doesn't work, C16 would "see" either 16 or 32 kB of RAM. (Cause it just tests writable ones just from the beginning, and doesn't notice if second working block is between 32-48k). I did the upgrade on mine at 1986 - the memory chips weren't cheap then for my budget - switching the power and seeing the thing work was some of the memorable things of my life =)

I saw a c64 back in '92 that was in for sale in a pawn shop, it had the keyboard raised to allow more ram chips to be piggy backed to the existing ones. Simple way of boosting the ram size, must have been 4 stacks high for a total of 256mb. But why they needed to go that high I don't know.

@JanBeta 4 жыл бұрын

Maybe they did some high level GEOS work, I think that was able to run from RAM almost completely. I've never seen a piggy back RAM expansion in the C64. Interesting idea.

@@JanBeta Here's an article for the same done with a vic 20: paradroid.automac.se/vic20ram/ I've heard some Amigas were hacked this way also as ram expansions were terribly expensive back then, I know, I still have a fast ram accelerator in my A1200, it cost as much as my Amiga did or close to it! Mind you, it was a great machine with an 020 in it.

I was not aware you could even make this mod happen at all, but hey realistically it's possible that you could get it up to 64kb since it does have at least some similar architecture to the 64, but anyway good stuff as always Jan!

@JanBeta 4 жыл бұрын

Thanks! Yes, the architecture is made for addressing 64k. Basically the same processor like the 6510 in the C64 but running at a higher clock speed (which is why it fails so often, too). ;)

No, the only thing they have in common is a similar CPU. The rest of the architecture varies quite a lot, especially graphics/sound are handled differently (by the TED chip).

17:00 : I'd say the opposite - precision sockets are for removable chips, like GALs, and EPROMs, and for prototyping, while regular sockets are for permanent installation. Chip in regular socket sits slightly lower than in precision one. Regular socket also ensure a better contact with chip pins, but the wipers deform more easily, when chip is reinserted too often.

@JanBeta 4 жыл бұрын

Yeah, that makes sense, too. I just find it more difficult to insert chips into the precision sockets without bending/breaking pins. That's why I argued that way. For stuff that is permanently changed around, I'd go with ZIF sockets or something like that rather. ;)

@francoisleveille409 4 жыл бұрын

Having used hundreds of both types of sockets I can assure you sockets with machined pins go slack and start making bad contacts very quickly if you insert/remove more than half a dozen times. This is especially true if at one point you insert pins that are slightly larger. The contact petals inside will widen permanently. The absolute best sockets are double leaf. My prefered brand is the Diplomat DL available at Digikey. I used one to test nearly 1000 PLAnktons on a C64 board 250466.
