32V filesystem images to verify code against.

by Jacob Moody

Hello TUHS, I recently have been working on the Plan 9 fs/v6fs and fs/v32fs programs, another member of the community had noticed bugs within them and I wanted to verify that the new code is working as expected. I haven't had an issue verifying v6fs using files from the TUHS archive but v32fs has proved to be a bit more tricky. After a little bit of work we were able to get the 'file2' located at https://www.tuhs.org/Archive/Distributions/USDL/32V/ to mount and read files. But given that all the files here are binaries it was a bit hard to make sure we're getting the correct information. I attempted to cross reference the files I get against the file2.tar also located within that spot in the archive but I am getting tar errors when extracting this file, so its not exactly obvious if what I am checking against is correct. So I would like to ask if someone here knows exactly what the sha1sums of these files are supposed to be and/or has another image with known contents I could test against. I will preface this with the fact that I am not very well versed in old UNIX filesystems so please let me know if I've missed anything. Thank you, Jacob Moody

Unix System V on the Public Domain 32000 (NS32016 chip set) reproduction

by Andrew Lynch

Hi I am interested in reconstructing the Public Domain 32000 (PD32) which appeared in 1986 edition of MicroCornicopia. It claimed to run Unix System V on a PC 8-bit ISA board using the NS32016 chip set. Does anyone remember this system and/or have any interest in it? Here is a link from Hackaday more fully describing the effort: ISA bus slave NS32016 processor board | Hackaday.io Thanks, Andrew Lynch

Re: Mills' initial implementation of FTP - best citation?

> From: Paul Ruizendaal >> the ambiguous phrase "had the first implementation of FTP", which >> has been flagged as needing clarification > From RFC 354 ... and from RFC 414 Those are NCP FTP, a slightly different protocol, and implementation, from TCP FTP. (The code from the NCP one was sometimes recycled into the TCP one; see e.g.: https://github.com/PDP-10/its-vault/blob/master/files/sysnet/ftpu.161 which has both in one program.) These RFC's you listed are obviously pre-TCP; the first TCP RFC is RFC-675. (The first RFC that even mentions TCP seems to be RFC-661.) RFC's are all NCP-related until around #700 or so, when the mix starts to change. Maybe the "needing clarification" refers to these two different FTP's? Without an explicit classifier, does that text refer to NCP FTP or TCP FTP? Noel

Re: Mills' initial implementation of FTP - best citation?

> From: Bakul Shah > He was part of NSFNet, so could have got first FTP on NSFnet or a > later version of FTP. You all are talking about _two separate FTP's_ (as I pointed out previously). If you all would stop confusing yourselves, you'd be able to sort out the bogons. In this particular case, the NSFnet appeared at a _much_ later stage of the growth of the Internet (yes, it is spelled with a capital 'I'; the morons at the AP were not aware that 'internet' was a pre-existing word with a _different meaning_) than when Dave was working with the Fuzzball, and by that point there were _many_ TCP FTP's (e.g. the ITS one I previously sent the URL to the source for), so the 'first FTP on NSFnet' is a non-concept. The best bet for accurate data is to look at the TCP meeting minutes from the IEN series: https://www.rfc-editor.org/ien/ien-index.html Looking quickly, the first one that Dave appears in might be IEN-160, "Internet Meeting Notes -- 7-8-9 October 1980". (He wasn't in the "Attendees" lists of any of the earlier ones I looked at.) Look in the "Status Reports" sections to see if he says anything about where he's at. The one for this one says: "Dave described the configuration of equipment at COMSAT which consists of a number of small hosts, mainly LSI-11s. ... COMSAT has also used NIFTP to transmit files between their hosts and ISIE. The NIFTP software was provided by UCL. ... COMSAT plans to .. arrange a permanent connection to the ARPANET." I have no idea what a "NIFTP" might be. Also, there is a reason that serious historians prefer contemporary written records, not people's memories. Noel

It may be impossible to provide hard evidence. From RFC 354 it seems to me that the protocol took on a recognisable shape around July 1972 and from RFC 414 it seems to me that there were a number of implementations by November 1972, and unfortunately Dave Mills is not mentioned. His recollection may well be correct, but finding proof he was the first in a 4 months time slot 50+ years ago may be too ambitious. https://www.ietf.org/rfc/rfc354.txt https://www.ietf.org/rfc/rfc414.txt Maybe the internet history list can shed some more light on the matter: https://elists.isoc.org/mailman/listinfo/internet-history

(Off topic) Dave Mills

Dave Mills, of fuzzball and ntp fame, one time U Delaware died on the 17th of January. He was an interesting, entertaining, prolific and rather idosyncratic emailer. Witty and informative. G

Mills' initial implementation of FTP - best citation?

by Royce Williams

What is the best public, unambiguous, non-YouTube reference I can cite for the late David Mills' initial FTP work? I see that the wording on his Wikipedia page has the ambiguous phrase "had the first implementation of FTP", which has been flagged as needing clarification, so I intend to provide it. In both this interview: https://conservancy.umn.edu/bitstream/handle/11299/113899/oh403dlm.pdf ... and this video recording of Mills himself giving a lecture at UDel: https://youtu.be/08jBmCvxkv4?t=428 ... it's quite clear that it's literally true - he authored, compiled, installed, implemented, and tested the very first (and apparently second) FTP server. But Wikipedia's guidelines discourage YouTube-only citations, and the text in the interview seems insufficiently detailed to have citation value. What is the best reference I can cite? Thanks! -- Royce

Are you offering to donate your labor in terms of typeface design, or will it be a type of deal where the community will need to collectively pitch in money to cover the cost of you doing it professionally? In either case, the "C/A/T-printed document" of most value to this project would be the same one G. Branden Robinson is referring to: > If you don't have my scan of CSTR #54 (1976), which helpfully dumps all > of the glyphs in the faces used by the Bell Labs CSRC C/A/T-4, let me > know and I'll send it along. I won't vouch for its high quality but it > should be comprehensive with respect to coverage. The paper in question is Nroff/Troff User's Manual by Joseph F. Ossanna, dated 1976-10-11, which was indeed also CSTR #54. The document is 33 pages long in its original form, and page 31 out of the 33 is the most interesting one for the purpose of font recreation: it is the page that exhibits all 4 fonts of 102 characters each. Here are the few published scans I am aware of: 1) Page 245 of: http://bitsavers.org/pdf/att/unix/7th_Edition/UNIX_Programmers_Manual_Seven… 2) Page 235 of: http://bitsavers.org/pdf/att/unix/7th_Edition/UNIX_Programmers_Manual_Seven… 3) Page 239 of: http://bitsavers.org/pdf/att/unix/7th_Edition/VA-004A_UNIX_Programmers_Manu… 4) Page 499 of: https://archive.org/details/uum-supplement-4.2bsd Question to Branden: the scan you are referring to as "my scan", how does it compare to the 4 I just linked above? If your scan has better quality than all 4 versions I linked above, can you please make it public? M~

Re: PCS kernel sources

Somehow it went into > a folder and has lurked unseen for way too long. > > Does anybody know any more about PCS Unix and, if so, where should > I place the code that Holger has donated into the Unix Archive? I don’t know much about PCS Unix, but I did come across many references to Newcastle Connection (and Unix United) when researching early networking and the various approaches to giving early Unix a networking API. I think there is no other set of surviving sources for this. Maybe Holger disagrees, but I would say that PCS Unix is best placed in the “Early networking” section. By the way, for those interested, here is a start to read up on Unix United: https://en.wikipedia.org/wiki/Newcastle_Connection To some extent, it is similar to the “RIDE” software developed at Bell Labs Naperville by Priscilla Lu and to S/F Unix developed by GWR Luderer at Murray Hill. As far as I know the sources for both of those have been lost to time, afaik.
