36bit still in use ?

From: Sean Caron Sent: Thursday, December 04, 2014 2:56 PM Oh, quite a few more were made. They were used in-house at XKL for software development and CAD work as well as electronic mail and day-to- day computing. They were finally fully retired a few years ago. It was public information. List price for a minimal configuration was $125,000. That comprised: 1 XKL-1 processor 1 XMG-1 memory (32MW @ 36b/W) 1 XNI-1 Ethernet interface (four 10baseT/AUI ports) 1 XRH-1 SCSI interface (four FASTWIDE differential ports) 1 DDS-2 DAT drive (internal) 1 4GB Seagate Barracuda SCSI drive (internal) with special microcode to allow formatting at 2304 bytes/sector (= 512 words = 1 page) The backplane had 7 slots, so additional memory and peripheral ports could be added. We also OEM'd the M4data 9914 9 track tape drive with a differential interface to allow companies to read archival data. Eventually we began using DLT IV drives in-house for backups, having learned the hard way that DAT was the wrong choice, and 9GB or 18GB disks. We'd have OEM'd those two, if we'd still been in the business of selling Toad-1 systems.
