I totally agree with saving these things Redwolf Sorry i don't know your real name but i was just pointing out my opinion about where he should look for the money too do...
there have been various looks at doing 360-370 simulation on itanium (porting existing i86 simualtors to itanium) going back to the earliest days of itanium design.
And, of course, *this* reminds me. Back when the Intel Mac was just a rumor, I suggested that, since unlike the Pentium, the Itanium has the ability of being operated in...
in the late 70s, early 80s ... there was fort knox. the low-end 360 & 370 processors were typically implemented with "vertical" microcoded processors ... that avg. out something like 10 micro-instructions per 360-370 instruction. the higher end 360-370 used horizontal microcode engines (being somewhat more similar to itanium).
fort knox was to replace the vast array of microprocessor engines with 801s. this started out that the follow-on to 4341 was going to be an 801-risc engine. this was eventually end ... i contributed to one of the analysis that help kill it. part of the issue was that silicon technology was getting to the point that you could start doing 370 almost completely in silicon.
one of the other efforts was 801-romp that was going to be used in the opd displaywriter followon. when this was end, it was retargeted as a unix workstation and became pc-rt. this then spawned 801-rios (power) and then somerset and power-pc.
there was also some work in fort knox on a hybrid 370 simulation effort using 801 ... that involved some JIT activity. i got dragged into a little of it because i had written a PLI program in the early 70s that processed 360-370 buttembler listings ... analyzed what was going the program and tried to generate a higher level representation of the program ... a couple recent postings
