The photo of the 16 bit sos chip... on the header of this group... was that from a 3000/30 system or?We have had one of thsee since the mid 1980s Thanks - Ed In AZ. Smecc.org. SMECC MUSEUM PROJECT

Can't really read the text but the sos chips in the 300 and 30/33 were
1AB2-6003 PCU 1AB3-6003 RASS 1AB4-6003 RALU My cpu selftest fails on test 23 RASS registers, but thinking it is support logic rather then the chip, but I have not figured it out yet.

The back of the chip isn't readable, the.marking on the die said 1AA1.

OK looking to see about the chip on this io group header that says 16 bit .... it is embedded in resin and has a blue background....... what 16 bit silicon on sapphire chip was first used in which HP system......

this embedded / attached photo is the one I am in question of.
the 3000/30 was first 3000 to use SOS technology Microprocessor.... but perhaps some workstations did also?
I have one of these HP cpu chips in a resin block as pictured on this group's home page..;
Just trying to figure which system used this processor first?
I have had this artifact since the mid 80's...
Looking to learn more!

My personal recollection: The SOS processor based on the HP 3000 architecture was specifically developed for Amigo (HP 300). The desk-sized HP 300 required a chip implementation of the HP 3000 processor because of its relatively small physical size. After it had been developed, the HP 3000 group went ahead and used it, after crippling and then killing off Amigo. https://en.wikipedia.org/wiki/HP_300
Development of the HP 300 SOS processor is more fully detailed here: http://www.hpl.hp.com/hpjournal/pdfs/IssuePDFs/1979-07.pdf
These events of the dark past are all artifacts of the federalist
approach to computer development HP was taking in the late 1970s.
Nearly a dozen HP divisions were all busy developing mutually
incompatible computer systems. IBM had experienced this problem in
the early 1960s and the unifying IBM 360 architecture resulted.

Steve -Thanks Let me digest this I had almost forgotten the 300 I had seen in it HP catalogs but never one in person. Thanks Ed#
