Need source for...

In the process of getting ready to upgrade my RQD11 QBus/SCSI adapter to near-current level, I discovered that I need a source for a hard-to-get PROM. Specifically, one of two parts should do it. Signetics 82HS189 AMD AM27S281A I've already checked with the manufacturers and a couple of local distributors. Yes, I'll be looking for these on my upcoming scrounging trip, but it would be a Really Cool Thing if someone could point me at a source for them. Thanks in advance. -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- Bruce Lane, Sysop, The Dragon's Cave BBS (Fidonet 1:343/272) (Hamateur: WD6EOS) (E-mail: kyrrin(a)wizards.net) http://www.wizards.net/technoid "Our science can only describe an object, event, or living thing in our own human terms.
