Sitenotice: 11/29/2018: The wiki is back. It turns out, some anti-virus product on my web server had an issue with the latest version of PHP. My server techs have resolved this issue, and things should be working again. During the investigation, I did restore to a backup from September. There is a chance that any changes done since then were lost, but I do not recall any edits. --OS-9 Al

8/30/2016: Massive re-work is being done on the InfoBox Templates. Read that page to keep up with the plan for that, and adding better keyword tags (categories) to all the pages. --OS-9 Al (talk) 15:28, 31 August 2016 (CDT)

Floppy Disk Drive Controler FD-501
Floppy Disk Drive Controler FD-501 Back

Controler

One of the more 'modern' controllers (mounted in a shorter cartridge than the older ones), this is also the only Radio Shack model ever to feature gold-plated card-edge connectors. Due to the much higher reliability of gold contacts over tinned PC fingers, this is my personal favorite among all of the Radio Shack controllers. This model was introduced in the 1986 Radio Shack catalog.

Drive

All subsequent drives were also white in color, but were mounted horizontally and used half-height drive mechanisms. They shipped with a single drive (Drive 0) in the lower 'bay', and a blanking plate over the upper opening. These drives could be upgraded to a dual-drive system by installing the second drive kit in the existing case. Note that the kit included, and all dual-drive installations in these cases require, a 12-volt cooling fan. The units run acceptably cool with a single drive, but not with two drives. The 4 cm diameter, 1 cm thick brushless fans (as used on many CPU heatsink assemblies) work well in these cases.
