I have it on rather good but anonymous [understandably] authority that 1.4 will work OK on an A1000, PROVIDED one is willing to give up some memory. The amount that must be given up could be as large as half a meg. No guarantees about 1.5 or later... From this I conclude that a rejuvenator is looking better and better... It also could explain the prior posting that the betas do not work on a1000. No expansion memory and they may not fit. Mind I have no 1.4, nor any agreements with C=. The above also could readily change, as 1.4 is after all only in beta and C= would have to be crazy to tie its' own hands by extensive discussions of this. The more things like scalable fonts, proportional font support, and the like get thrown into one's OS, obviously, the more space is required. [The old recursive proofs that one can always bum another word or two of code notwithstanding :-) ]. OS breakage is one of the things that is normal over the course of an architecture, even where the user mode instructions and OS interface are preserved. (Just try running current releases of, say, MVS on a 360/65, for example. RSX eventually would no longer fit the PDP11/34 quite a while back. It's mighty hard (though still barely possible) to get the latest VMS on a vax 725, and it may not run on a Microvax I at all. MSDOS 4.x still runs on the old 4.77 MHz 8088's, but is looking mighty lame there.) Fortunately, application breakage is less common.
