Well:-) Is there any possible way of doing any kinda modification to my Pro 350 to turn it into a Pro 380? (short of replacing the machine and/or system board!!) What I am wondering is if I can replace the 11/23 chip set with the J11 chip set, and if the rest of my periphials will still work? (I dont know if it is standard on all Pro 350s, but mine has the extra chip, that I think allows floating point instructions) Thanx Billy D'Augustine Azog-Thoth@cup.portal.com

If you could scrounge a Pro380 system board, you could probably replace the 350 system board with that. IMHO, having a 380 doesn't give much additional return. Oh sure, the chip is much more capable than the F11, but with super mode, I/D space, and cache permanently turned off, what real gain is there other than a little bit of CPU speed? I find the stupid disk controller in my 380 to be more of a problem in throttling the performance of the system. BTW, DEC did once put up genuine RSX-11M-Plus on the 380. The conditionals are still there in the Exec source to make it work. Haven't got around to trying it yet, but one of these days ...
