I was recently scanning the web for a Dilog SCSI board and stumbled across a "DLI Dilog" web site: http://www.dilog.com/unibus.html I called and chatted with Jon Klotz - who turned out to be a founder and partner of the original Dilog back in 1978. Amazingly, DLI Dilog still manufactures DILOG boards (mostly SCSI - but some serial) primarily for government accounts. As one might expect, the price of new boards is prohibitive for most of us as collectors ($2,500 or so for a SCSI Unibus or QBus board). They don't stock boards - they manufacture them from scratch when they get an order!!! They are capable of manufacturing a brand new board for every product that Dilog ever produced! Jon was great to chat with and knows a lot of interesting DEC history! I was just sorry he didn't have a stack of used boards he wanted to part with ;-) Cheers, Lyle -- Lyle Bickley Bickley Consulting West Inc.
