Maybe someone has a spare pair of mounting rails for a DEC RK05 drive, so
that I can finally mount it into my H950 rack?
Offers from all over the world accepted :) (I'm located in
Austria/Europe)

is anyone knowledgeable enough of their product line to give me (us) a rundown of these models, and characteristics (roughly) since their inception (1989 AFAIK).
I'm in the market for one, probably an older model, any condition, but not too shabby w/regards to sampling rate (let's say starting at 100mhz, they may not have gone any lower anyway).

That's an awful lot of schratzing around to accomplish what a simple
GUNRUP% sudo /bin/bash
will do for you. (I use this frequently on my Snow Leopard system.)

Hi Brian.
I just got on the list and I'm working backwards through the archives.
Couldn't reply on one of the existing ones. You did update the list,
so I'm guessing the vt220 and the 8" floppies actually are already
gone?

That's correct. There is a special disk to set up the hard drive. I
think you have to have this disk in drive A in order to read the hard
drive, I don't think one can simply boot a 1050 to harddrive. I plan to
work on this system over the next few months, I will document the process
on my site when I do. I also am knee-deep in projects at the moment.

If anyone bought any of those rl02 or other dec or classic disk packs
and media from ebay, please PLEASE read the contents out before
overwriting them!
I recently found a bunch of lost unix v5-era source code on erased space
on an image of a disk pack image from dennis ritchie, archived
unknowingly at tuhs, so who knows what other gems may be on those disks
in erased space?
dump them with dd, not with dump, since dump ignores or zeroes out blank
space. Tar obviously ignores blank space as well.

Hi,
I'm trying to re-create the source files for the Z8000 UNIX I have
on my Z8000 system (it is a S8000+ZEUS clone).
Easy programs like sync.c where easy. But when argc/argv is involved,
I'm not able to generate 1:1 matching binary code.
I'm working on /etc/unlink for now.
I tried the following C file:
char whatstr[] = "@[$]unlink.c 2.1 07/23/82 21:19:30 - 87wega3.2";
main(argc, argv)
int argc;
char **argv;
{
if(argc!=2) {
write(2, "Usage: /etc/unlink name\n", 24);
exit(1);
}
unlink(argv[1]);
exit(0);
}
The original ASM code for the beginning of main() until the argc
check is:
0042 abf3 dec r15,#4
0044 5df60000 ldl %0000(r15),rr6
0048 0b070002 cp r7,#%0002
The ASM code my C file generates is:
0042 abf3 dec r15,#4
0044 1df6 ldl @r15,rr6
0046 0b070002 cp r7,#%0002
keep in mine, that r15 is considered as the "stack pointer".
I wonder how to get the ldl from the original binary.
I also tried to declare argv with "char *argv[]" which
resulted in the same code. Forcing the compiler to store
argv into a register by using the "register" keyword results
in completly different code:
(sp = stack pointer = r15)
#17 adb unlink
ADB: P8000 1.6
? 0x0042/i
%0042: dec sp,#6
?
%0044: ld %0004(sp),r14
?
%0048: ld %0002(sp),r7
?
%004c: ld r14,r6
?
%004e: cp r7,#%0002
? $q
#18
Maybe the C compiler used to compile /etc/unlink differs from
the C compiler shipped with the system (maybe an older version)
but I don't want this to be true for now ;)
Anyone with deeper ASM and C knowledge than me sees what could
be done here?
Before someone asks - yes I'm sure the source file was in C
and not ASM based on the whatstr. Symboltable of the original
/etc/unlink is empty as well (striped binary).
