1+ GHz Commodore SX-64 Mod
Spider[DAC] writes "I just found this site, about a person who modified a Commodore SX-64 to contain a 1.2 GHz PIII system. It appears to be a really cool system, and apparantly requires some specially made hardware to make it all interoperate properly. A well-documented read, and definitely something to dream about doing yourself."
Destroying the rarest C64 ever made to change it in to a PC?
People that do this don't deserve to have old computers. (IMHO).
This is like taking a Model-T Ford and "converting" it into a Toyota Corolla.
If you could be told what you can see or read, then it follows that you could be told what to say or think - BoC
Chalk one vote for nostalgia and leaving rare and cool things alone.
...modified a Commodore SX-64 to contain a 1.2 GHz PIII system.
Hardly a 1+ GHz Commodore SX-64 Mod. More like a simple case-mod effort. Slapping a small form-factor MB into an SX-64 case is kinda cool, but it ain't that cool. Now, building a real C64 notebook or building a souped up C64 (not emulated) would be damn cool.
Woah, cut the guy some credit! This isn't just a case hack; he didn't just spend 4 hours with a dremel.
He went to the trouble of using the orignal keyboard. That means he designed and programmed a microprocessor to convert the matrix from the keyboard into the serial stream for the ps/2 port.
According to his tech page, he's going to build a switching power supply, which isn't easy to do right, to replace the 1U power supply he's currently using.
Oh, and there's the sound interface, too, more custom hardware.
Sure, he's using an emulator, but, he's also using a lot of the original hardware.
I'd like to see you do that.

This is Old News.
In the late 1980's, one of the Amiga luminaries, Dale Luck, got his hands on a Commodore SX-64 (when they were slightly less rare), hollowed it out, and stuck an Amiga 500 in it.
Apparently one of the toughest parts of the hack was getting the keyboard to work as the C-64 keyboard layout and electronics are completely different from everything else. Fitting the motherboard was also a bit of a squeeze. All in all, it was an amusing hack, but because the SX-64's color monitor was of such low resolution, it was a struggle to read, even at 640 * 200 pixels. So it was cute but, alas, not useful.
As others have already observered, gutting one of these rarities to stick a PC in it is just sacrelige.

No it's not. The VIC-20 used an 8-bit Motorola 6502 microcontroller. It's dead simple. If you took a university course in computer systems architecture, they might have you design a similar CPU for your semester project. They might even have you build it in VHDL, which you could synthesize onto an FPGA.
Some old systems are intersting for the nostalgia. Others are interesting for novel design. The CPU in the VIC-20 is far less interesting than the nostalgia gleamed from playing old games and reliving your childhood for an hour or so.
