You only need 3 wires. http://www.mathyvannisselroy.nl/xl600k64.htm

Based on experience, you may still get noise/jail bars coming through the display even with the SCCC / UAV installed if you don't have clean power or a decent ground from the vertical block. Once I fixed up the grounding issue, I had a very nice and clean picture on my 800 that surpasses the display in any of my other 8bits.

Bosconian is a work of art.

Here's a nice write up about the physics routine used in the demo. https://medium.com/@peterbudziszewski3/iocaste-physics-routine-1f86570cdc63?fbclid=IwAR1E6PFr5Sh4l1nM4JK57xwNSUTPktT4yHQdD1pid1vNTc3UoNRB65SaEZA

It's brilliant, definitely worth getting. Felt like I was a teen back in 1986 all over again and I couldn't put it down. Great reviews, definitely lives up to expectations and some of the old reviewers were back including Julian Rignall. Maddi did a pretty good review of it https://www.youtube.com/watch?v=vtF9o2Ulawk Don't miss out on the next one...

It's been a major pain from the beginning and resulting in many a blown 6526 CIA

I suppose it would only be an issue with a lot of upgrades ? I just have the SCCC which I purchased from you and the 800 doesn't draw too much. Though I believe this might change with someone like the Incognito. Just wondering if you still plan to develop the a personality board for the 800? I'll definitely be in line for one...

I'm hesitant on installing one inside my 800 for the same reason but since you've already done it you could try adding a choke ( just a hand wound ferrite core with 5 or 6 turns ) and a cap to implement a lc low pass filter. I had the same issue in another power supply I rebuilt but the symptoms were more subtle. Here's a really good video on how to implement one. https://www.youtube.com/watch?v=G-Llhy2ViUY

Yes it's fantastic, one of the best programs ever written. I used to load up that game just to listen to the tunes.

I'd say in 1985 for Apple and Atari. Commodore started using them in 1986. The answer is probably here https://tedium.co/2016/11/24/1988-ram-shortage-history/

Kyle22 showed me this ad from 86 and they look relatively cheap. The two 8 Bit DRAMs are still cheaper based on this ad. I have no way of verifying when the board was made and I'm not sure when 4464s were introduced, so perhaps those were factors. 4416s were in the 600xl in 83, so its highly likely 4464s existed but may have been too expensive to manufacture in large enough quantities at the time. So perhaps availability was the main factor.

I didn't have the upgrade at that point yet. So in order to keep using the machine....

At least they used good quality RAM chips and not the mT variety we all love so much. I no longer have this board, the OKI branded ram went straight into an 800xl. I'm not sure why they didn't just use the two 4bit DRAMs and 3 wires. The ram upgrade before installing the Antonia 4Mb board.

I haven't given this a bash yet. But it look likes a lot of fun.

Reminds me of my old one.

Chipped is usually ok but I always check their values just in case they're off. I've only had one game ( it was a King Of Boxer ) constantly crash because of missing and broken decoupling caps. Once I replaced those the game was stable.

I see more Turbo Chameleon 64 carts being sold just to play this without slowdowns.

The cheats, glitches work because he took the original rom and reverse engineered the binary into his own source code. Whilst the game logic is the same. He would have re-written a large portion of the code to work around the c64s many limitations and make things work in a different way, each system is different with its own unique strengths. The scrolling relies on a very specific technique to make it work on the c64 and he also would have completely re-written the sprite engine to handle as many objects as it does. The sound & music would have been a challenge as well but the SID and NES APU can produce similar sounds.

If it's the one I'm thinking of then it's exempt from being pulled.

google search, you'll find it.
