(C64) An 8-bit Commodore Business Machinespersonal computer released around September 1981.Prototypes were (apparently) made before Christmas 1980 (andshown at some computer fair).The CPU was a 6510 from MOS Technology (who were awholly owned subsiduary of Commodore at this time (?)). TheC64 had 64 kilobytes of RAM as standard and a 40-columntext, 320x200 pixel display generating composite video,usually connected to a television.DMA-based memory expanders for the C64 (and C128) allowed128, 256, and 512 kb of RAM. Several third partymanufacturers produce accelerators and RAM expanders for theC64 and C128. (Some, risking a holy war, compare this toputting a brick on roller-skates). Such accelerators come inspeeds up to 20MHz (20 times the original) and RAM expandersto 16MB.The C64's 1541 5.25 floppy disk drive had a 6502processor as a disk controller.See also Commodore 65.["Assembly language programming with the Commodore 64", MarvinL.

Procollagen Proline Dioxygenase
- mixed-function oxygenase that catalyzes hydroxylation prolyl-glycyl-containing-peptide, usually in protocollagen, hydroxyprolylglycyl-peptide. The enzyme utilizes molecular oxygen with a concomitant oxidative decarboxylation of 2-oxoglutarate to succinate. EC 1.14.11.2.
