I received my 1541 Ultimate-II+ a couple of months ago and love it (which reminds me, I really need to do a write up of it), so the news that Gideon had announced a new product today certainly caught my attention.
The Ultimate-64 is a an FPGA implementation of the entire C64 board. This means it has all the ports of an original C64, so you can attach tape & disk drives and hook it up to your old Commodore monitors. But, of course, that's not all - HDMI output and the full functionality of the Ulimate-II+ are built in.
Of course whenever I see news of someone re-implementing the C64, the first thought that crosses my mind is: "Ahh, that's all very nice, but what about the SID?". Emulated SID will be included (I assume including the ability to emulate dual SID chips), but purists will be able use actual 6581 & 8580 chips!
There's no launch date or price just yet, but this is something I'll definitely be keeping my eye on.
