[TUHS] Re: 1972 UNIX V2 "Beta" Resurrected

Hi, So I've tested SIMH again with my reconstructed RF disk image, and this time it worked. I must have used the s1 kernel and the unix-june72 init(7) when I previously tested it, my bad. sim> dep system sr 173700 sim> go 173700 :login: root root # ls -la total 42 41 sdrwrw 7 root 80 Jan 1 00:02:02 . 41 sdrwrw 7 root 80 Jan 1 00:02:02 .. 43 sdrwrw 2 root 620 Jan 1 00:01:30 bin 147 l-rwrw 1 root 16448 Jan 1 00:33:51 core 42 sdrwrw 2 root 250 Jan 1 00:01:51 dev 49 sdrwrw 2 root 110 Jan 1 00:01:55 etc 54 sdrwrw 2 root 50 Jan 1 00:00:52 tmp 55 sdrwrw 7 root 80 Jan 1 00:00:52 usr # It's great that it works under SIMH... However, this still does not help with installing this version of UNIX the intended way. The intended way is to boot from the s1 tape, which would load the cold kernel, initialise the RF, and provide you with a minimal set of tools so that you could use tap(1) to restore the distribution from the s2 tape. The showstopper here is the s1 tape - it is missing /etc/passwd, so you will not be able to login when booted from s1. sim> dep system sr 1 sim> boot tc0 HALT instruction, PC: 000414 (JSR R0,10762) sim> c :login: root root Can't open password file :login: Since you can't login, there's not much you can do :(. For now, my hand-rolled RF disk image is the only way to get a working copy. My SIMH config file: set cr disabled set xq disabled set rk disabled set hk disabled set rha disabled set tm disabled set rx disabled set rl disabled set tq disabled set dci disabled set cpu 11/20 set cpu 32K set ke enabled set rf 2p set rf enabled att rf s1s2unix_rf.img <-- RF disk image set tc enabled set tc locked att tc s1.itp <-- s1 tape load m792low.load <-- Modified UNIX ROM from unix-june72 project dep system sr 173700 go 73700 <-- Low address used by the modded ROM P.S. This kernel is unmodded, which means it supports only LF, not CR, so use ^J for ENTER. Sincerely, Yufeng
