1x SCSI CD ROM drive

I just got around to testing this really old caddy based SCSI CD-ROM drive that came with the big pallet of Mac stuff.

Apparently it's made by Chinon, and it's only 1x. Yes - 1x. The slowest drive I owned until now is 2x. I had to buy a caddy off of eBay for it. It seems to work fine using the CD Sunrise driver. Very interesting old piece of technology here. I'll probably hook it up to one of the older CD-less Macs just because I can.

Most programs required a 1x CD drive, even then... Whats the Revolutions per second on a 1x drive anyway?

wow, that brings up old memories. I remember that when my dad, my brother, and I built our 286 w/ 2MB memory and a 80MB hard drive, that we went out and bought a brand new SCSI hard drive and 8-bit ISA card for it. I think it cost us more than the computer we built was worth (kinda like a blu-ray drive is worth more than some computers) It musta been around $600-900, i forget.

Anyways, have fun! albeit if it's slow, it's a cool thing to say you have owned (Btw, ours wasn't caddy load)

A 1x drive is 150rpm, which works out to 2.5 revs per second. Slowwwww.

Apple used a numbering system in the early days that embedded the rotation speed. A CD300, for example, is a 2x drive, and a CD600 is a 4x. Got kind of unwieldy as the speeds shot up, so they eventually abandoned this system.

Yeah...i think the last one that they called with that name was the AppleCD 600, although I have heard of the Apple 8x drive being called the 1200, the 12x drive being referred to as the 1600, and even the 24x drive being referred to as the AppleCD 3600. But i can't confirm any of that...my AppleCD 8X and 12X drives both say exactly that, "AppleCD 8X" or "AppleCD 12X".

If they continued, we would have the AppleDVD 7800 now on the 52x, 7200 on the 48x and 4800 on the 32x.

I had an IBM 1x tray load CDRom. Not sure where it is now, but it may be gone as the machine it was in decided to smoke up one morning.
