There's a little blackout around 8:11 in the video, sorry about that, something went wrong during editing! The full sentence I wanted to say is "Another point for the iComp case is that it can actually fit a PCB with a socket with an EPROM in it." Half of that is missing but re-rendering and re-uploading would take some time and effort so I hope you are satisfied with this little written correction. ;)

Fun fact. Jupiter Lander (and Kickman) can also be used as a dead test cartridge, although not as good as the real dead test, they (at least) will work if the kernal and/or basic rom is bad.

@JanBeta Жыл бұрын

Yes! That's why I have Jupiter Lander as the second ROM on the original Dead Test cart I made. I heard Commodore used those games for testing C64s in the factory before they made the Dead Test/Soak Test cartridges. :)

@mal2ksc Жыл бұрын

I thought it might be easier to just grind down the end of the case so the board is long enough in the "right" position. (Or to put it another way: Maybe the board isn't a few millimeters too short, maybe the case is a few millimeters too long.) Edit: No, there's a "shelf" inside the shell that would also somehow have to be moved back the same amount. It looks like the answer is to relocate the center post by some means, but all the ones I can think of have problems. The simplest would be "tweak the model, print again" but he didn't print it himself.

A little trick i learned to make hot glue seem less hacky, get black hot glue! It instantly looks way more "pro" haha. I use it all the time for securing fragile solder connections.

@JanBeta Жыл бұрын

Haha, that's a good idea! Black looks more pro instantly. :D

@mal2ksc Жыл бұрын

I'm not sure that applies inside a red case. Black hot glue does certainly have its uses though! I found mine at a Daiso store. One complication to bear in mind though: if the material making the mix black is carbon, which it often is, then it's conductive. Since it's mixed into plastic, it probably won't be conductive over any long scale, but if applied to the pads on a PCB, it could potentially short them together. If overheated, the particles tend to settle out, which is how I came to realize that it was just clear plastic with black powder in the first place. It probably won't be a problem with a layer of solder mask in between, so this is limited to contact points and other bare patches.

@madmartigan1498 Жыл бұрын

Me: Why don’t you just use two separate cartridges instead of making one combined? Jan: Because I can. Me: Great stuff!!! ;-)

@JanBeta Жыл бұрын

Yeah, I wanted to make a proper cartridge for quite a while but never got around to it. Very happy I finally did. My original DIY carts were just quickly hacked together to get the job done (and they have worked for much longer than I ever anticipated)! :D

@mal2ksc Жыл бұрын

Given that _one_ of the options is likely to be productive, it saves wear and tear on cartridge slots because in a sense, he's always using the right tool. Adrian Black has a double-ended cartridge where one end is a dead test and the other is diagnostics, and although that's convenient enough for keeping them in the same place, he does have to extract it, spin it around, and re-insert it to switch roles. The truly merged version doesn't need to. Since the trick seems to be to use a bigger EEPROM and then toggle the higher address lines manually, I wonder how many cartridges could reasonably crammed into one package. I have a feeling this will be limited more by easily available EEPROMs rather than by the number of bits that can be crammed into a rotary encoder.

@@JanBeta I think that's pretty common in every language -- there's something specific to a purpose, and it gets a name that makes perfect sense. Then the name gets applied to everything that somewhat resembles the original, and the name no longer makes so much sense because they are put to different purposes. It's like calling modern smartphones "phones" when people spend most of their time avoiding using them to make voice calls. 😆

Zaxxon seems to be a good test game as it really requires a good PLA to function

@danielmantione Жыл бұрын

Well, it is mainly very senstive to a specific PLA flaw. It doesn't serve as a good test for the C64 in general, nor does it mean that a PLA that survives Zaxxon is automatically a good PLA.

I just recognized your composite-to-hdmi converter. Have you modded it to have a direct composite input? Mine came with an additional (ugly) composite/svideo-to-scart adapter.

@JanBeta Жыл бұрын

Yes, it's one of those inexpensive SCART-HDMI things. I hacked in some RCA jacks and a heatsink a while back. I even made a video about that hack job: kzfaq.info/get/bejne/ibFko5xznqzNpGw.html Served me well ever since, even if it doesn't look great. I only use it for testing stuff on the bench though because the lag is quite significant and makes gaming a bit painful.

@Zentauri77 Жыл бұрын

@@JanBeta Thanks for your reply. I just watched the video and the RCA jacks mod is something I will definitely do too. I use the SCART-HDMI converter to connect my amiga 1200. For some reason I need to use the composite input. Using Scart directly does not seem to work. The OSD tells me it detects a 50 Hz signal, but the screen stays white. I even used a differen scart to hdmi converter (MATR CS34L from reichelt) with the same effect. As for the heatsinks; Since the case is made of metal I think it may be an reasonable idea to screw a hetsink/heatpipe to the casing which then connects to the top of the chips - not unlike what commodore did with the TED chip.
