I found one btw and I paid quite a bit for it when you include shipping. Something like $130. I think it's the 1st CD drive ever made for a computer but might be wrong about that. You should be able to find about 20-30 titles for it if you count PAL and NTSC. Psycho Killer and Town With No Name are the favorite 2 games I've found for it so far. Someone told me my A570 was broken in another post when I complained the sound output was low. See you're supposed to put your audio out RCA red & white to this audio-in jack on the A570, then from the A570 to the speakers/home theater receiver you're using with it. I recommend any old computer speakers with it. I don't know maybe something is wrong with mine but I really don't think so. Just a tip if you have problems with not hearing the sound.
Amplified speakers or headphones is what I mean* Also a neat trick I used was I put the sound out to some old computer speakers then out from the headphone jack to the home theater receiver, and that really let me get great sound out of it. Note: you might not have this problem, but if you do, just do this to fix it. It's a lot easier than trying to fix a sound processor.
one last thing* the cd caddies are real fragile, but they're quite easy to replace. one of the push-down releases on one side broke right off from use. It was loose when I got it. Symptom is the disk caddy will not snap in easily you'll have to jiggle it a little bit. But I did a search for "cd caddy" on ebay about 10 seconds after it broke and found one for $8 including shipping! So buy a couple extra cd caddies if you're going to use it a lot. wait till you get it first. the one i ordered had a picture and happened to look identical to the one i had though it didn't say it was a commodore cd caddy. I think there was a uniform size for them.
