Re: [EXTERNAL] History of EPICS

[Maren Purves via Tech-talk <tech-talk at aps.anl.gov>]

Just a minor addition:
I know that Mary Fuka came to JCMT from LANL but I do not know what
she worked on at LANL.
I was told (don't remember by whom of the two) that she and Peregrine
McGehee (now at SLAC, we worked at the Caltech Submm Observatory at
the same time, about 30 years ago) once worked on the opposite ends of
the same beamline :)

I recall William Lupton (Keck) and Nick Rees(UKIRT,JCMT) spearheaded the initiative to bring it to the Astronomy community. This was later supported by Maren, Allan Honey (drvSerial/drvAscii) collaborating with Jeff Hill and later Kevin Tsubota (Keck). When the Gemini project started many of the RGO staff developed EPICS related work packages: VMIC-5588 Reflective Memory, PMAC1 support, AllenBradley PLC5, GenSub Record (Andy Foster, Andrew Johnson et al), Xycom 240/566 (now acquired by Acromag?). I believe Mary Fuka (JCMT) worked on the predecessor to EDD/DM called GDCT(spelling?). Does that sound right, Maren?

With Till Strauman (SLAC at the time) and Eric's help, I got the 2700 building for RTEMS 4.9.2 and it was accepted in EPICS 3.13 circa 2009. Gemini has since phased out the 167's and the 2700 is the ubiquitous Gemini controller. The 2700 now supports RTEMS 6.1 and development branches EPICS 7.
