Project to recreate C64. And Atari, And BBC And Spectrum And Apple II....

Is it your USB power supply?

Nope!

Golden Platypussy?  Sounds James Bond-ish.  Is this some sort of high tech spy equipment?

I guess the platypus is a hallmark for Australia, because it lives there (and with an US family in one of my favorite cartoon series). The gold plating can be useful for BGAs, but on the photo it really looks like bragging .

Finally a 100% backward compatible C64 would be very difficult, with the VIC as the most difficult part.

FYI the Visual6502 project has decapped one to reverse-engineer, although won't be done anytime soon probably.

VIC is indeed quite difficult. There are some interesting interactions with VIC and CPU at the C64 hardware and the demo coders tend to mis-use those really well. Muxin sprites, openng borders, expanding gfx up/down, some special modes (Fld) and the Display-hw cycle stealing are hard to emulate with 100% correctly.

For those who have interest.. this seems to be quite a good intro

Yeah.. I know I'm old. C64 was my first own computer and also the first machine I made some code for money. Oh, if I had back then only known half of the things I have later forgotten ...

And 100% SID compatibility would be difficult, too. Some years ago an effect was developed, which can play 4 channels of 8-bit samplerate, 2 channels of SID synth sound and all filtered:

Of course, it doesn't work in VICE.

And there are still unsolved mysteries. One was just explained this year by lft, why on some machines the VSP effect crashes, an interesting analog metastability effect: http://www.linusakesson.net/scene/safevsp/index.php

worked fine for me, albeit without video.  it sounded identical to the video as well...  in fact, the video says it should play on vice. 

[FrankBuss]

You are right, I've tested it with VICE 2.2, looks like they have improved it, it works without problems with VICE 2.4 (and the re-SID setting). But no video.

meh... Its been done

I think that was just a PC with a commodore slant on the looks.


You can't really beat the Ellsworth C64 DTV joystick; it was the perfect form factor released at the perfect time using the perfect selling platform at the time. 
"QVC purchased the entire first production run of 250,000 units and sold 70,000 of them the first day they were offered"

Is this his utube channel?

btw if your spoon breaks, i've got some spare ones here! ;-)

I'm sure I read somewhere that she (jeri) was contacted by Commodore USA to do some work (I guess on the C=64 part )

Is it your USB power supply?

Nope!

Spandau Ballet?

[Stonent]

Haven't people already made replicas of the processors in these computers on FPGAs? Even the legendary Commodore sound chip appears to be recreated.

Even Jeri made her own version of a Commodore. I love her projects, they are quite creative.

There are AVR based SID emulators. One even sits on a tiny circuit board that is plug compatible with the original SID chip.
