Could I interest anyone in my collection of BYTE magazines, dating from
issue #16 (DEC 76) to Vol 12 No 2 (FEB 87), missing Vol 11 No 11, for
pickup in the San Francisco Bay area in California?

Hello, Did this collection find a good home ??
Else, maybe I can offer one.
Regards, Gerard

All this talk about RL01/02s and RK05s has reminded me that it would be
nice to get the device handler for my dual Xebec hard sector floppy drives
connected to my -8/M. I have only a couple of bootable disks with a couple
of versions of OS/8. A lot of them are corrupted from best I can tell.
I've developed a way to dump all of the readable blocks from disk over the
serial port, which, as you can imagine, does take a while. I've also
developed a little program that can parse the data into RIM format to be
disassembled.
>From the OS/8 Software Support Manual, I can see that the handlers should
be located within blocks 16 through 25, octal. Should I be attempting to
dump those blocks and try to reverse engineer it that way, or is there a
way in OS/8 to directly dump each individual handler?
Any tips would be much appreciated.
Thanks,
Kyle
I quit fiddling around with TME and went to QEMU like I should have in the
first place. Following this page exactly:
http://en.wikibooks.org/wiki/QEMU/SunOS_4.1.4, I got barfage that looked
like this:
Extracting the sunos 4.1.4 sun4m 'uucp' media file.
Extracting the sunos 4.1.4 sun4m 'Games' media file.
Extracting the sunos 4.1.4 sun4m 'Versatec' media file.
/usr/etc/install/tar/export/exec/sun4_sunos_4_1_4/versatec: cannot
extract file.
add_services: 'tar xpfb
/usr/etc/install/tar/export/exec/sun4_sunos_4_1_4/versatec 32k 2>>
/etc/install/suninstall.log' failed.
Please check local media device
/usr/etc/install/tar/export/exec/sun4_sunos_4_1_4/versatec
Press <return> to continue
You have sunos 4.1.4 sun4m release media volume -1 mounted
Please mount sunos 4.1.4 sun4m release media volume 1
Press <return> to continue
I upgraded QEMU. That didn't fix the problem. Then I looked at my SunOS
4.1.4 iso. The file export/exec/sun4_sunos_4_1_4/versatec is a corrupted
tar. I can manually exclude that package, but I'd like to have something
that really works all the way, particularly for when I get my hands on my
real Sun hardware again.
Does anyone know where I can find a known-good ISO? The md5sum of my iso
is this:
927fa22042a70bf21a80be9393b15770 sunos_4.1.4_install.iso
Second question...
With the resulting install of SunOS 4.1.4, I'm having trouble getting the
emulation talking to the outside world. Through trial-and-error, I
figured out that QEMU is assigning the guest the IP of 192.9.200.1 and the
host as 192.9.200.2. Plugging these into what I see at the wikibooks.org
page, I get results that seem like things went okay, but pings and telnets
timeout. What did I miss?

The thread on using two RL02 drives with OS8 made me think about this, but I didn't want to confuse that thread with my tangential topic.
Is there any difference in RL02 drives and/or disk packs for PDP-8 systems vs. PDP-11 systems (other than the obviously different controller cards for OMNIBUS/UNIBUS/etc.)? If so, how do I evaluate and identify the specialized bits and pieces?
I ask this because I have a few RL02 drives waiting for my PDP-11/44 project, as well as a pile of RL02 disk packs. If there are differences for PDP-8 vs. PDP-11 applications, i.e. due to different word sizes, then I'll need to keep my eyes open for mismatched parts in my pile. Conversely, if and when I get a PDP-8 system with an RL02 controller card, I'll wonder whether I can use any of the pieces I already have.
I seem to recall reading in recent months about some DEC drive and/or disk pack that would have different hard sector notches or some such thing for PDP-8 vs. PDP-11 applications, but I don't recall which type of drive it was.

Hah! Another proposal for computer classification!

Minicomputer: can keep a basement warm.

Fred, you da man!

True, with a caveat. You can modify an RL02 drive to be capable of
reading both RL01 and RL02 packs, but it requires a hardware hack.
When I worked at DEC, we had such a drive.
However, an RL02 drive cannot reliably write RL01 packs.

i wonder if anyone out there might have an old pentium 1 board since i
have a few pentium 1 processors and even an amd k6-2 but i want to be
able to use the processors and maybe build up a nice old windows 95 box
or something nice. if anyone might have any just let me know
