(DIY) THE FINAL CARTRIDGE III+ FOR COMMODORE 64

ROM hazırlamak için ayrıca bir program vardı, şu an baktım ama bulamadım.
Aşağıdaki linklerde hazırlanmış farklı ROM'lar var.

I shared it at "Schematic and Layout" downloads.

Thanks for your sharing.

I understand what you said, but I think 5 USD for 10 pieces of PCB is not too expensive. Because of PCBWay supports amateur PCB designers like me, I share my PCB designs only on the PCBWay site. PCBWay donates 10% of the cost of every PCB sold to PCB designers. Thank you for asking.

Sincerely thank you for your support. We are committed to building a more excellent community, providing a platform for more electronics enthusiasts to showcase themselves.

it is not a switch. it is optional +5V power output, if needed for sd2iec or something else.

I answer myself. In the comment below I see that it can be used. Apologies

74ALS – Advanced low-power Schottky. Same technology as 74AS but with the speed/power tradeoff of 74LS. 4 ns, 1.2 mW, 4.5–5.5 V.

74LS – Low-power Schottky. Implemented using the same technology as 74S but with reduced power consumption and switching speed, due to larger resistors. Typical 10 ns gate delay, remarkable (for the time) 2 mW dissipation, 4.75–5.25 V.

Hi JMJM, I did not try 74ALS. I think it will probably work, but I can not guarantee. If you try, I will be happy to learn the results. Thank you.

Thanks for replyng, I'll give it a try and let you know. :)

Hiya, I've finally had chance to build and test a couple of these, and I can confirm that it seems fine to replace the 74LS133 with the ALS version.The ones I've built are working great. Thanks C64iSTANBUL! :)

Thank you JMJM. :)

I just put one together using 74ALS133 and can also confirm it works.

Thank you Jason Ginsburg.

Hi! Does all the components come with the PCB if i order one from PCBWAY?

I'd rather get the STL's here for FREE: https://www.printables.com/en/model/119336-final-cartridge-iii-case

Hello Antony Oldham, you can use standart 2V-3V (3mm or 5mm / red, green, yellow) LEDs. Thank you for asking.

Thank you, Archon is a Electronic Arts game and Electronic Arts company is still active working, so threre is copyright problem. I can say that; special shaped cartridge is not suaitable for all games because of some thecnical reasons. My email adress is c64istanbul@bikom.com , thank you.

Hello, Thank you. Some games like Mario Bros, Boulderdash, Pitfall... have still copyrights. Many software companies like Activision are still working. I can only make cartridge of abandonware software. I do not know much about PCBWay remuneration policies, I prefer 10pcs. and Chinese Registered Post, it is cheap and reliable. If you like, you can share your case designs under related PCBs. Thank you.

Good point, esp. with Mario Bros I believe but many ppl already made Zaxxon/Super Zax. Carts. As for a case my personal choice is one out of Plexiglass/Polycarbonate clear to show off the Cart but later a 3D Printable one that will have to not hide the Cart...will share for sure! Thx.

Yes, there is an advantage of using 27C020 (27C2001) DIP32. 27c512 is 64kilobyte, 27c020 is 256kilobyte, with 27c020 you can use "PROGS" menu, this is "PLUS" function. With 27c512 you can make old sytle final 3 cartridge (not plus) (without PROGS menu) (see pictures). ---------- W27c020 is elecronically erasable memory, 27c2001 is Ultraviolet (UV-C) erasable memory. w27c020 can be erased and programmed more times than 27c2001. For this final3+ circuit they both do the same job.

That seems to be a very good option...I really seem to like the Projects you have especially Aztec Challenge! I'd love to make a Custom Case that was Clear to show off the Cart itself although I would use a Red PCB. You have a knack for making some Great designs including Falcon Patrol and Pole Position... you could probably create a Great Mario Bros (new version of course) or a Zaxxon/Super Zaxxon. There is a Zaxxon Cart but no great graphical PCB, lol. Funny that I have a lot of family in Turkey, but mostly in Istanbul? Btw, I badgered PCBWay to finally add an affordable Shipping to Canada, although risky option in China Post, so that making a couple of PCBs would be feasible.. Gonna try and place one order of a few items to save on combined shipping, I hope PCBWay provides some remuneration to you, let me know and thank for the quick response.
