The two I've seen that are SCSI are the TK50Z-FA (for use with VAXStation 2000) and the more generic TK50Z-GA (less proprietary on the SCSI side than the FA). Depends. If you're talking the bare drive with the 26-pin Berg header on the back, it's a proprietary serial interface which requires the M7546 (or similar) tape controller. Such were often installed in MicroVAX II and III, and could also be found on the MicroPDP-11 series. If you're talking external case with a pair of 50-pinners on the backside, that could be either an FA or a GA. Such were used with systems like the VAXStation 3100 series, or anything else that needed a TK50 on SCSI. -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- Bruce Lane, Owner and head honcho, Blue Feather Technologies http://www.bluefeathertech.com // E-mail: kyrrin(a)bluefeathertech.com Amateur Radio: WD6EOS since Dec.
