Computer Surplus is selling the Adaptec 4070 SCSI->RLL ST506 adapter for $129. You could then use the RLL drive with the 2090 controller as a SCSI drive. They are in San Jose CA and their number is (408) 434-1060. They also have an ad on pg 366 of the December BYTE. I've done business with them before and my only complaint was that they wanted to much for some of the S-100 gear they were selling. Note they usually sell used stuff that has bee tested to work. --Chuck McManis uucp: {anywhere}!sun!cmcmanis BIX: cmcmanis ARPAnet: cmcmanis@sun.com These opinions are my own and no one elses, but you knew that didn't you.
