I count 75 manuals under pdp11/rsts on bitsavers



Sounds like a lot, I know (and I've downloaded them all) but for all 3 versions 
of V06 (A/B/C) there are only 16 manuals total. Some are things like Runoff and 
TextEdit which are semi generic, but others like the Sysgen manual there is 
only V06A, nothing for B or C.  Same for the System Manager's Guide.  And the 
Install notes.  And so forth.  V7 is worse. V7.0 was a major, major change in 
RSTS/E and there are only seven manuals for it.  Only two relatively minor 
manuals for 7.2 and that's it.  V8 has only a beta level internals manual.  V9 
has a good coverage but tht won't help you for earlier versions much.

This collection in UK manuals for version from 4a to 10.1 That's significant 
for a RSTS/E fan.  It could be hundreds of manuals total if each version 
released is represented.

Yes, it is. Fascinating!
And right now jdownloader is fetching me a local copy, as opposed to
previously not working with that one video for some inexplicable reason.
So thanks for reminding me to try again.

What do you find incorrect or insufficient about Terry’s explanation in that 
email to the darwin-kernel list? 

I get that you would like POSIX unnamed semaphores but they aren’t required for 
conformance and there are specific issues (that Terry relates) that really 
would have made them difficult to implement in a way that’s both compatible 
with how they’re used in practice (e.g. casting to pointers and sticking them 
in shared memory region) and maintaining binary compatibility (a decade’s worth 
of shipping software at that point that expects sem_t to be a 32-bit type).

Origins of nameless semaphores and Apple's non-support thereof

[David Griffith via cctalk]

I recently tripped over the fact that MacOS does not support nameless 
POSIX semaphores.  When attempting to use them, I get a complaint that 
they're deprecated.  I can't fathom why Apple would do that.  I found this 
post explaining it, albeit not very well: 
https://lists.apple.com/archives/darwin-kernel/2009/Apr/msg00010.html. 
It seems that Apple yanked out support, but elsewhere 
(https://intfiction.org/t/macos-frotz-users/41553/5) I'm told that Apple 
did it because BSD 4.4 didn't implement them.  I was fairly sure that it 
did.  Does anyone have a more satisfying answer?

PIC programmer

[brian--- via cctalk]

Hi all,

I have, surprisingly, a non IBM 1130 related issue to ask about. I have a
PIC16C55A-04/P 28 pin plastic MPU that I would like to reproduce --- but
don't have a PIC debugger on hand and in fact don't know whether or not the
existing device is code protected. (If it's code protected, then the path
forward is going to be very different).

Does anyone have the ability to check one of the chips that I have here is
code protected so I can see if I should pursue this any further?
Located in the San Francisco Bay Area but can mail a sample chip.

Thanks!
Brian

I too have a load of RSTS docs I’ve been trying to move on for a few years. 
Antonio was going to take them but ended up in the US so they’re still all in 
my hallway, you’re welcome to those too!

Re: RSTS collection in the UK

[Pete Turnbull via cctalk]

Hi, Al.

This sounds slightly familiar - Jay contacted me a year or two ago about 
a similar lot but the donor never got back to me.


Anyway, I would be happy to collect these on behalf of Jim Austin, for 
the Computer Sheds:  http://www.computermuseum.org.uk/
We'd be particularly interested in the RSTS stuff, as we have very 
little of that.


Please pass on my contact details.

RE: RSTS collection in the UK

[Dave Wade via cctalk]

Al,

 There is a DEC Legacy group in the UK, started for the DEC Legacy Meetings but 
now sometimes carries more general e-mails. Some one on there may be able to 
archive these.
  I don't think there are any museums who have the facilities to take this on. 
A few would take the stuff and put it in store.
 
Dave

RSTS collection in the UK

[Al Kossow via cctalk]

We received this offer, it probably makes more sense for someone in the UK to 
get the lot.
Is there someone at a collecting institution that would like to take this on? 
Email me and
I can forward your contact information to them.

I have discovered the myriad of Facebook vintage computing groups, so I
have begun posting my sale lists there as well.  However, I will always
post notifications of new lists here and on the VCFed forums 24 hours
before I unleash them on the FB groups, which results in a deluge of
activity.  In this way, I give you guys first stab at the action on the new
stuff before the hordes descend upon it.  You are welcome.

As always, please contact me directly by e-mail to inquire about an item.

Thanks!
