“Ultimate” in that it will be the last thing ever completed. I’ve had this one in pieces and in design for a while. About 2 years. Too long? This is the shell that will house my own C64 I used to play on back in the day. (It’s a mess, it needs it, really.)

I have only really assembled the aesthetic parts and built the case. May I present, the RX-64R, my take on the SX-64.

No you may not present it. It isn’t finished. The panel is bare on the other side. It’s like the Wizard of Oz’s builders’ crack back there.


- 7″ LCD screen
- 2 port switchable joystick
- 4 analogue controllers for synth applications
- Audio feedback loop
- control panel printed on weatherproof labelling (design here)
- Multi-cartridge changer controlled from panel with tri-colour LED indicator
- SID2SID board with noise reduction mod and on/off switch
- switchable kernel with JiffyDos and my own modified kernel
- 1541 ultimate cartridge controls and LEDs on panel
- reset button
- selectable character set rom – 3 sets available.
- retro moog monosynth style casing

* sometime in the future.

(Yes I have the red & green LEDs the wrong way round.)

To Do list:

- burn EPROM with multiple kernels
- remove kernel ROM and add DIL socket
- burn EPROM with multiple character sets
- remove character ROM and add DIL socket
- build power supply with added ampage
- strengthen / brace panel and monitor in place
- cut clear persepex sheet to size to cover bare C64 motherboard
- “wire it all up” and “do a bit of troubleshooting”

As you can see I have a lot of work to do on this baby. I’m glad it’s starting to take form at least.

The panels on the unit are aluminium top panel leftovers from a Pactec PT-10 case, as used in the MB-6582 and x0xb0x. The joystick is from somewhere in internet land I can’t remember. I have a whole bag of spares though.

If you’d like to make your own, click the thumbnail below to download the control panel graphics to print out. You could use the individual panel sections for your own mods. It’s always great to see my MSSIAH/Prophet64 key graphics in use around the place, would love to see someone use this panel design. You just gotta do a little bit of cutting and drilling. A hole punch is pretty much perfect for cutting the holes in the sticker(s) for your toggle switches.

That’s the problem with being obsessed with C64s. I get a flood of ideas and it takes me 2 years to render one into something near reality. This one has actually given me an idea for a DTV mod that I won’t tell you about.

“Stay tuned for updates as and when I get another day off work like Christmas.”

Happy new year all

    Mate that’s real cool would like to get some pictures of the inside.
    How many hours went into that, did you plan it carefully or did it grow as you introduced items.

    Stunning! Dude, if you ever finish and want to sell it, drop me a line :)

    One of the best looking C64 hardware trickeries I’ve seen! Great work. If you want to add a stupid feature, I have an idea: feed the 1541U-audio into the SID-input. Dumb modularism ™.

    that one looks plain awesome. would like to see that spaceship in action.

    Curious if you had completed your C64. Very inspirational… I’m currently modifying a few right now.
