Hobbit Processor from AT&T

[Michael Z Slater]

Does anyone have any details on the "Hobbit" processor from AT&T?
According to press reports, it is a low-power RISC processor that will be
used in a hand-held computing/communicating device under development at
Eo Corp., a GO spin-off. Is this a reincarnation of the old AT&T CRISP,
or something new?

Hi, I'm interested in this question too. I searched the web for some materials, but I found only these docs that are mentioned in Wikipedias. But there's an interesting thing: in the Bitsavers' site there's a document, with title "ATT2100 Microprocessor Hardware Specification" - file name: ATT2100_Microprocessor_Hardware_Specification_Mar91.pdf It is in the /att/hobbit folder. Maybe it is the same processor? I couldn't find out what it was, and the Hobbit has a number (ATT) 92010 and later 92020.

So my question is that what is the ATT2100 Microprocessor and how it is related to the Hobbit?

I was at Eo (and so am one of the few people to have programmed this
thing) and I'm pretty sure that this is the Hobbit.

Great! I found another document:
Title: "Integrating a floating point unit into the AT&T
Hobbit(tm ) microprocessor"
URL: http://preserve.lehigh.edu/cgi/viewcontent.cgi?article=1214&context=etd

This one is containing short descriptions of parts of the Hobbit architecture.

What I'd like to know is: How did you manage to unearth
a 22-year old usenet post?!
