  • For a complete treatment of IDE interfacing to 8-bit CPUs (particularly the Z80 family), check out issues 56, 63, 64, and 66 of The Computer Journal. There is a simple IDE interface for the Z80 called GIDE (Generic IDE). It should be possible to adapt it to other 8-bit processors. There is an article about it on the TCJ Web Page. Click on 'GIDE'.

• Hello Friends I've a general query about CD-ROM drives in computer: Does CD drive's life lessen due to excessive playing of Audio/Video CDs or not? If yes, then how a ACD/VCD player keeps working well for so long? I would be grateful if anybody could provide a reasonable explanation! Thanx-a-lot.
