I said I'd do it gratis for screen credit, and they wouldn't do it. I think they would be better off building a wooden box with blinking lights in it if all they want is a movie prop. I doubt they are going to find anyone willing to sell or rent them a KA or KI for this purpose. I wonder what kind of movie needs an Alto, DG Nova, and a 10..

I'd have to check the Alpha architecture book, but I think current Alphas with their 8 KB page size only have a 43 bit virtual space. Doubling the page size means doubling the # pointers in a page table and an extra bit for each of the three page tables an address traverses. So when Alpha has a 64 KB page, it will have a 55 bit virtual address space. Celera Genomics has a system with 64 GB of RAM, that's 36 bits of bytes, a -10 would only need about 34 address bits to cover 64 GB. -Ric Werme -- Ric Werme | werme@nospam.mediaone.net http://people.ne.mediaone.net/werme | ^^^^^^^ delete Vote www.harrybrowne.com for President!

[The R10k CPU chip provides 64 bits of virtual address (well, 63 bits usable in user mode) and 48(?) bits of useful physical address out to the pins, and the Origin 3000 architecture can use up to 44(?) of them with the current support ASICs.] And, yes, we've shipped systems that big (512 CPU, 1TB RAM) already, and have promised NASA one twice as big . So 36 bits of byte address for physical memory definitely sounds too small, to me at least... [And *way* too small for virtual addresses!!] -Rob ----- Rob Warnock, 31-2-510 rpw3@sgi.com Network Engineering http://reality.sgi.com/rpw3/ Silicon Graphics, Inc.

Would 72 or 64 make more sense now?

Having downloaded the GPL release of the ITS kernel source code from http://pdp10.nocrew.org/its/swiss/, I noticed that the sysdoc archive included some mail archives in an old babyl-ish format. I therefore wrote a Python 2.0 script to read these in and convert them to Unix mbox format, attempting to preserve the original data as much as possible. The script's at http://pils.us-lot.org/~azz/itsmailbox.py; mail me if you'd prefer me to make the converted files available somewhere (the original files are under the GPL, so I assume it'd be OK).
