I've mentioned tangentially this a few times, but over the weekend I
finally got around to dusting off the code and getting it running:
https://github.com/dancrossnyc/rxv64.git
rxv64 is a rewrite of MIT's xv6, which in turn, reimagines 6th Edition
as a purely pedagogical system, implemented in ISO C for 32-bit SMP
x86 machines.
Building on xv6, rxv64 is implemented in Rust and targets 64-bit
x86_64. It works well enough to boot up, run a shell, and run
commands, but it doesn't really have much of a userland at present.
I started this as a pedagogical tool, being something that one could
point working engineers at as an example of a "real" operating system
implemented on real hardware in Rust. The code could surely be made
safer and more comprehensible, but cycles are short at present, and
it's better to just get it out there.
Have fun.

Hello!
For some time now I've had both this address, and my original address
which was on another service altogether subscribed to this list. And
starting some time earlier, it would not show a full thread, it would
show partial contents, the latest was the work by Dan Cross. In fact
With that being last, ah, straw I decided to do that.

i do remember the fun of changing the baud rate of an async line on the Honeywell level 66 mainframe at college. This required shutting the whole machine down, removing one of the cards, and the (very careful) use of a wire wrap tool.

Good evening folks, I'm doing some research lately into the typesetting style apparent in the various UNIX System V guides I've scanned to archive.org. Their typesetting style is unlike that of the MM papers published with 3.0 and 4.0, but the contents seem to have continuity with the text in these collections.
Well, in my searches sometimes telecom documents from the Bell System come up too and in materials from the 70s and 80s I started noticing that familiar typesetting in telecom stuff such as that hosted here https://www.telephonecollectors.info/index.php/browse/bsps-bell-system/bsp-…
The earliest example I could find is 1969, so certainly at least a publication style that predates UNIX, but what I can't tell from my searches alone is if this style implies some non-UNIX typesetting system through and through or if there was a macro package dreamed up at some point between 1969 and 1982 that was in place by the time of the System V documentation.
Just to detail specifics of the publication style, the commonalities I've found are the use of specifically bold numbers for page numbers, having the doc title and call number in the outer upper corner of pages, and just the fonts themselves look very similar. As an added note, the fonts used in the telecom documents and System V guidance documentation also resemble those in the copyright statement pasted on the cover of the extant PDF of the fifth edition UNIX manual. There is also some resemblance to the visual style observable in USG Program Generic and adjacent documentation (for instance the 1976 kernel description of PG 2 or the MERT 0 documents). This typesetting style is not seen in known research, CB, nor PWB until 5.0. Was there some separate typesetting system used in the broader System that, say, WECo may have taken up when they took over documentation between 3.0 and SVR2?
