Unfortunately I have sold my C64 long, long, long time ago only because space is a huge factor. I have here in this table:
1) 22" Monitor underneath it PS 2
2) Beside this keyboard I am typing with right now is my xBox 360, and to the left of the PC mouse is my Amiga 1200.
3) Right in front of my Amiga 1200 is a laser printer and the monitor Commodore 1084s
4) to the right of the Amiga 1200 is it's mouse and right beside that the end of the table and couple of inches away from that is my bed.
So you can see space is an issue here...and I already stored my Apple IIgs in the closet as I cannot use it now. So Commodore 64 with it's own power supply, cable, disk drive 1541-ii and it's own power supply....plus floppy disks is just not going to cut it for me.
I am ok with no sound.....I will play C64 games with no sound. You are right however...that sound emulation will consume much more 68k CPU power...That is why I am wondering in frodo if I can use SID hardware card to solve my problem.
