Asr-10 Cd-rom, Zip Drive, Additional Ram, Manuals.......

[BigLex]

I just bought a rack.. looking at ebay for accessories.. for the zip and cd-rom drives, will any scsi drive do? I see zips for just over $10.. but for the cd-rom drives, I see some that have ASR listed under the title selling for over $60, but theres other scsi cd-rom drives for much cheaper. Is there any particular features it needs to have to be compatible?

And how much does RAM typically sell for? Theres 2 sellers trying to get $20 for the 16 mb including shipping.

Theres a few different manuals- the original one, Essential Sound Manual, and Musician's Manual (388 pages).. I think all are from Ensoniq- do the latter 2 cover anything different from the regular manual?

Thanks.
