So far I managed to uncompress the files with the custom version of compress on NetBSD/simh. I then created a .tap file according to the reference in FORMAT. I'm using the following config file for simh 3.0.1: load -r ka655.bin set rq0 ra82 at rq0 ra82.dsk set tq tk50 at tq0 quasijarus0a-dist.tap boot cpu Here's a transcript of the very first attempt of booting off the tape: $ ./vax 43cfg VAX simulator V3.0-1 KA655-B V5.3, VMB 2.7 Performing normal system tests. 40..39..38..37..36..35..34..33..32..31..30..29..28..27..26..25.. 24..23..22..21..20..19..18..17..16..15..14..13..12..11..10..09.. 08..07..06..05..04..03.. Tests completed. >>>boot mua0: (BOOT/R5:0 MUA0 2.. -MUA0 1..0.. = Clearly, stand boots. I'm hopeful that 4.3-Quasijarus0a will indeed run on simh. For some follow-up questions... Standalone format supports hp and up disks, but simh only emulates RL and RQ controllers - which means that the Ultrix utilities to label a cold disk must be ported or recreated to the simh host platform. Of course, it may well be that applying a hex editor to the disk image will suffice. Am I correct that Quasijarus supports RA82 disks (using the ra type) and the TK50 tape (as a tms)?

Yes, for political reasons I needed to make the 4.3BSD-Quasijarus compressor a version of compress, not gzip (can't have any GNU), but I wanted to have the higher compression ratio of deflation, so I created a new version of compress that supports deflation in addition to the original LZW algorith. You can find the new compress in components/compress.tar either on my FTP site or in Warren's archive in the 4BSD area. > > Is there a set of 4.3BSD-Tahoe Vax distribution files that's complete? > > Not that I know of. "4.3BSD-Tahoe Vax distribution" is an oxymoron. Berkeley released the Tahoe tape with Tahoe binaries, no VAX binaries. I was the one who compiled the Tahoe source for the VAX, and the result was 4.3BSD-Quasijarus0. OTOH, you may be referring to the fact that the Tahoe distribution in the archive is broken. Yes, it is. Unfortunately there was an unrecoverable tape read error. > > Finally, do you know of any 4.3BSD version that will install and run on > > simh?
