VCF East update - three keynotes, TWO original Apple 1, etc.

by cctalk＠snarc.net

Hi classiccmp'ers. VCF East starts in just 8 days from now. It's at the InfoAge Science Center in Wall, New Jersey, USA. Three keynotes: John Blankenbaker (Friday), Stewart Cheifet (Saturday), Ted Nelson (Sunday). Three dozen hands-on exhibits. TWO original Apple 1 computers, including one up-and-running. Oh and there will be a Kenbak-1 also. :) A dozen-ish tech classes. 8-bit game programming competition sponsored by Hackaday. Consignment room. And the on-site, year-round computer museum is now TWICE as large as before. Come see awesome stuff such as our circa-1965 UNIVAC 1219B mainframe. Kids get in free on Saturday/Sunday. All the details, along with online ticketing, are at http://vcfed.org/wp/festivals/vintage-computer-festival-east/.

KY11-LB prints, and versions

by jnc＠mercury.lcs.mit.edu

So I'm in the process of repairing a couple of M7859 KY11-LB -11/04-34 Programmer's Console boards, and the existing FM Print Set was kind of hard to read in some areas, so I looked online for another set, and although I didn't find one, I noticed several other people with the same issue - asking for a better set. My brain did eventually turn on, and I remembered DEC's habit of putting prints for included devices in with print sets for computers, and with that in mind, I managed to locate another set in the -11/34A print set; that one is a lot clearer. To my surprise, they showed a slightly different board from the one in the existing FMPS available online: in the later version, the four 8093 quad tri-state buffers between the UNIBUS data lines, and the internal bus, are replaced by 74173's. I'm not sure quite what motivated this change - no documentation that I know of refers to the existence of two different versions. The PCB is slightly different, but the ROMs are apparently all the same, so >from the point of view of the i8008, the two versions must look the same. (And given where the change is, it can't make any difference to the interface between the card and the front panel, CPU boards, etc, so either version should work anywhere.) Anyway, the version in the -11/34A prints didn't include the actual front console, plus to which the prints there had been heavily marked up by someone at some point. So I have produced a new set of prints: http://ana-3.lcs.mit.edu/~jnc/tech/pdp11/MP00015_KY11-LB_Jan78.pdf which includes the front console pages from the earlier set, and a cleaned up version of the pages from the -11/34A set for the M7859; hope this is useful to someone!

Document treasure trove

by Paul_Koning＠Dell.com

While looking for DECnet documents, I noticed that there's a very large collection at http://manx.classiccmp.org/collections/antonio/dec/ . Probably not news to many, but in case some had not seen it... Among other things, there are two CD collections MDS-1997-10 and MDS-2000-01. The former contains a rather obscure document, the DECnet Phase IV Token Ring datalink spec. That also includes the Phase IV routing layer tweaks necessary to support token ring -- or other datalinks if you don't want to use the AA-00-04-00 prefix. paul

MEM11A Status

by ggs＠shiresoft.com

Hi, The board layout is complete and has passed all of the design rule checks from the board house. I?ll be ordering some boards for me to assemble and test next week. I have also received a quote for ?turnkey assembly? where I hand them the files and get back fully assembled boards. In order to get the price reasonable I have to have 25 *firm* orders for the boards. I?ll be charging $395/ea + shipping. If folks could let me know (private emails please) as to the quantity that they want (don?t send $?s yet) so I know I won?t be $1000?s in the hole on this before I order the boards. The timing is that I?ll probably place the order for the boards (assuming sufficient interest) in mid-May. I?ll let folks know when I have the minimum quantity. BTW, this is for the MEM11A 128KW SPC memory board (not to be confused with the UMF11). TTFN - Guy

3B2 C compiler and Assembler

by lists＠loomcom.com

Now that I have my 3B2/300 up and running, I'd like to get developer tools installed. Unfortunately, I can't find any of them on the web anywhere. Apparently what I'm looking for are the following packages: * "C Programming Language Utilities" * "Software Generation Utilities" * "Extended Software Generation Utilities" Apparently these three packages are contained on five diskettes. If anyone has these, or can track them down, please let me know! -Seth

Front Panels - PDP-8/e Type A Availablity

by rodsmallwood52＠btinternet.com

Hi Guys I now have a limited quantity of PDP-8/e Type A Front Panels ready to ship. Type A is the early kind where the selector switch runs from the 12 o'clock position anti clockwise to the six o'clock position. If you have a paid order for a Type A then it will ship to-morrow. The others will go in the order that I receive payments via PayPal When they are all gone you go to the top of the list for the next batch. PayPal Payment as follows $150 per panel plus shipping at $20 per panel, You can order more than one but to be fair everybody who orders in time gets one and the rest to follow. Don't worry there will be a new batch of Type A next week. It gets better there will be a Type B release to-morrow. Same rules as above. Same Pricing Even better PDP-8/f and PDP-8/m artwork is complete and panels will be made starting to-morrow. Release 1-2 weeks Rod (Panelman) Smallwood
