To: SPRUCESUPPORT cc: Putman, Swinehart, RWeaver I'm not sure who is responsible for this Maxc directory anymore. Rick Tibari was the originator. It only had a Message.Txt file in it. The file managed to grow to 52 pages and acquired a disk error on page 25. I have used Teco to write the Message.Txt file to BadMessage.Txt and then MSGFIX to get the mailbox going again. I would like to know who the cognizant (responsible) person is for that directory so I can update my records, etc. Can either of you help me out?

In-reply-to: RWeaver's message of 14 Nov. 1980 2:50 pm PST (Friday) To: RWeaver cc: SPRUCESUPPORT, Putman, Swinehart Some combination of Brian Badenoch and I are responsible for this directory. We'd rather not change it to be a distribution list on Cabernet because we'd both like to able to read the messages that are put there, and that would require never emptying the mailbox, a no-no in the Grapevine world. Let's leave it the way it is. Thanks for the first aid. Dan Swinehart 15-DEC-80 16:24:08-PST,1215;000000000000 Date: 15 Dec. 1980 4:21 pm PST (Monday) From: Swinehart.PA Subject: Request for Information To: SpruceInstallers↑ cc: Ramshaw, Swinehart Lyle Ramshaw and I are contemplating some improvements/repairs to Spruce that would be easier to do if we could use bank 1 of Alto extended memory. Some even more desirable improvements could be obtained if we could use additional banks. So what we'd like to know is: 1. What is the memory size of the Spruce Alto(s) for which you are responsible? I think DMT will tell you the answer for sure. 2. (Assuming that all now have at least two banks) Do you think your organization would be willing to shell out the bucks for additional memory, if we could substantiate significant performance improvement? 3. Can you provide us with file names for any files that currently break Spruce ("page too complex" message or the equivalent)? Send your answers to me only, please. If you're not sure whether you are the one responsible for a system, pretend that you are, and I'll deal with the duplicates. Please forward this message to anyone who is not on SpruceInstallers↑ but who you think can contribute. Thanks for your help.

Rm. 1077 Gene Day Versatec will give a talk on CORJET and Other Competing Marking Technologies Several different marking technologies are competing in current and planned raster-scanned hardcopy applications. For narrow paper webs (11 inches and under) there is no clear winner and several different methods should find long-term usage depending upon the cost, resolution, speed, and quality requirements of the application. For wider paper webs, which are of particular interest to Versatec, the situation is somewhat clearer. Many of the technologies are not easily scaled to large sizes and electrography, in its various forms, seems to have a clear advantage. CORJET, a new ion-projection method begun at PARC, offers the hope of lowering the cost of electrographic writing while improving the image quality as well as providing a direct (non-transfer) plain-paper method.

The prints are now in the PARC (Bldg-35) Library. If there are sufficient requests, I'll have extra prints run off. The pictures will be in the library for about two (2) weeks. P.S. THEY ALL TURNED OUT REASONABLY WELL 11-JAN-81 13:26:57-PST,1283;000000000000 Date: 11 Jan. 1981 1:25 pm PST (Sunday) From: Ramshaw.PA Subject: new Spruce.Fonts To: SpruceInstallers↑ cc: Ramshaw Clover has moved to a new Spruce.Fonts, and those other T-80 Spruce printers that would like to follow suit are cordially invited to do so. The file to pull is, of course, [Ivy]<Dover>Clover>Spruce.Fonts. This dictionary is about 13000 Trident pages in length, with 832 fonts. I estimate that it would take about 8 hours to pull over a lightly loaded 9.6KBaud line. If you would like the fonts but don't want to tie up the InterNet that extensively, send me a physical T-80 pack and I will put the new dictionary onto that pack. New Fonts: - special Laural/Cholla font - all new TEX fonts (3000 pages worth) for new TEX - new versions of ReDraw vector drawing fonts, that aren't thickened in the vertical direction to compensate for a slow Dover laaser modulator - new large sizes of TimesRoman and Helvetica Bold, as an alternative to TimesRomanD and HelveticaD, from Pellar. - TimesRoman18BI The font-level documentation on [Ivy]<Fonts>CloverFonts.Press has been updated already, so pull and post the new version when you update your printer. The character-level documentation will be updated sometime soon, Lyle 11-JAN-81 22:44:18-PST,2337;000000000000 Date: 11 Jan 1981 22:40 PST From: Ramshaw.PA at PARC-MAXC Subject: new fonts, TEX, and MetaFont To: PaloAlto↑, TexUsers↑ cc: Pellar.EOS, DEK@SU-AI, Ramshaw NEW PRINTER FONTS: Clover is now using a new font dictionary that contains: - all new TEX fonts for use with the new TEX - a special font for use with Laurel/Cholla - new versions of the ReDraw vector drawing fonts that aren't thickened vertically to compensate for a slow modulator - TimesRoman 18 Bold Italic - TimesRoman and Helvetica Bold in 24, 30, and 36: alternatives to TimesRomanD and HelveticaD. The file [Ivy]<Fonts>CloverFonts.Press describes the new dictionary at the font level. The character level documentation contained in CloverCharacters*.Press has NOT been updated yet, but will be soon. Other printers that run Clover's font set will presumably be updated over the next couple of weeks. In any case, please update your Alto disks by first retrieving the new widths dictionary from [Ivy]<Fonts>Fonts.Widths, and then reinitializing Bravo by uttering Bravo/I. [Special note: If you are a user of the PressEdit/N hack, also update your copy of [Ivy]<Fonts>Fonts.Names.] For those interested in such statistics, this font dictionary is 26.7MBytes in length, and contains 852 fonts. NEW TEX: A new version of the SAIL implementation of TEX is also released, on Maxc1 and Maxc2. The new TEX uses the pretty new fonts. The old TEX is no longer available. Press files produced with the old TEX will continue to print using the old Computer Modern fonts for as long as those fonts remain on the printers (>3 months). For a description of the features and changes in the new TEX, see: <TEX>Help.Txt --what is TEX and how do I run it? <TEX>Jan1980Changes.Txt --what just changed, and how do I adjust my files? <TEX>Errata.Txt --all known errors and changes in TEX since the Digital Press version of the Manual. The Mesa version of TEX has not yet been updated, but will be. NEW METAFONT: The new fonts were produced with a new MetaFont that can output Dover-style fonts and widths directly. For documentation, see: <MF>Help.Txt --what is MetaFont and how do I run it? <MF>Errata.Txt --all know errors and changes in MF since the Digital Press manual.

Treleaven, University of Newcastle-upon-Tyne, chocolate connoisseur, possessor of happy feet, and author of: "A Simple Single-Chip Building Block", "The Design of Highly Concurrent Computing Systems", "Data Driven and Demand Driven Computer Architecture", "A Concurrent Computer Architecture and a Ring-based Implementation", "A Computer Supporting Data Flow, Control Flow and Updateable Memory", "A Multi-processor Reduction Machine for User-defined Reduction Languages" (to name a few) will speak on distributed computing. His Abstract: For a decentralised computing system consisting of many computing elements (whether geographically distributed mainframe computers, or miniature computing elements within a single board or even chip) the prerequisite is a "naturally" decentralised model of computation. This will allow a large number of computing elements to co-operate in the execution of a program. Computational models used in parallel (data flow, control flow, string and graph reduction) computers help us to identify the attributes of such a decentralised and general-purpose model. This seminar examines these four classes of parallel computational model, and presents a classification for their underlying concepts. In addition, it gives a "kernel" computational model - called recursive control flow - which represents a synthesis of these underlying concepts, and hence supports as sub-models data flow, control flow, string and graph reduction styles of computation. Phil will be here Thursday and Friday, and at Caltech the following week.

As you know Maxc1 will be departing soon. Directories that remain after Maxc1 is gone will become Maxc2 directories only. Over the years Maxc1 users have changed their passwords as requested by administrators. In many cases the password on Maxc2 was not changed in parallel. This will pose a problem when you find yourself trying to login on Maxc2 and you can't remember that ancient password. I have identified 164 directories which fall into this category. I am aware that some of these are Maxc2 users already. I will try to make an intelligent decision as to who these are and I will leave those passwords alone. But, admitting my humanness, there are bound to be errors. In changing the password I have to key in two rather long octal numbers (10 to 12 characters each). I feel that the first fifty or so will be relatively error free but my skepticism grows beyond that. Sometime latter this week I will send out another message informing you that I have completed updating the Maxc2 passwords. At that time you should try logging in on Maxc2 and verifying that your password is correct. Message me if you run into problems. Also, if you know your Maxc2 password is different and you don't want it changed, message me immediately.

The major reasons are program efficiency and giving more information about the data flow withing the program to the programmer. I have explored the use of type inference in a strongly typed language. The hope is that such a system would be able to keep all of the strong typing without requiring the user to specify types as rigorously. I have developed a program which infers types in Mesa using the general Unification Algorithm (of Milner et al). This works very well, and runs in 'near linear' time, for a broad subset of Mesa. I will demonstrate a simple system for partially specifying types in Mesa and show examples of of how type checking and type inference can be done identically using this system. I will show how constraints in a Mesa expression can be easily captured. The limits of this algorithm will be shown, and ways (that are not, alas, linear) are shown to extend the algorithm. ------------------------------------------------------------ 14-JAN-81 15:08:18-PST,781;000000000000 Date: 14 Jan. 1981 2:54 pm PST (Wednesday) From: RWeaver.PA Subject: Files Moving to Maxc2 To: PaloAlto↑.pa Reply-To: RWeaver cc: RWeaver Any files remaining in the following Maxc1 directories on Saturday morning (06:00, 17 Jan.) will be moved to Maxc2 to partially accomodate the migration of three disk drives to Maxc2. 134, ALTO, ALTODOCS, ALTOFONTS, ALTOSOURCE, BBN-134, BOOTFILES, CSL-ARCHIVES, DEUTSCH, EXEC, FONTS, GAMES, IFS, KBA, LAUREL, MPS, NOVA, PRESSFONTS, PRINTING, PRINTINGDOCS, PUB, PUP, RFC, SAIL, SERVICES, SIL, SOURCES, SPRUCE, SPRUCESUPPORT, TAYLOR, THALES, & X-TELENET.

I will let you know when the fix has been installed. At the request of Gill.WBST, here is separate information about new fonts for people who want to merge new fonts into their existing dictionaries: Laurel/Cholla font: There is only one font, and it can be pulled from [Ivy]<Ramshaw>fonts>Laurel384.oc The only widths file available for it is the one that Prepress will give you from the rasters: that is, no scalable widths. TimesRoman18bi: Pull if from [Xeox]<FontCenter>Fonts>TimesRoman18bi.oc. Large TimesRomanB and HelveticaB sizes: The fonts are (or at least were once) on [Ibis]<Fonts>BigAPS.fonts. Rumor has it that AltoFonts in APS format are available from XEOS; and Brian Badenoch (Badenoch.PA) has some Alto fonts where the codes below #40 share the same bitmaps as the corresponding eight-bit codes. [I haven't done anything about these Alto fonts.] ReDraw: ReDraw 1.0 is newer than Sept. 1980, and better in the sense that graphic objects are not thickened by one bit vertically to attempt to compensate for a slow Dover modulator. To get the full benefit of the new version, your Dover should have the new NewVec fonts as well, since the old fonts had this thickening built in and the new ones don't. The new fonts are on [Ivy]<Ramshaw>ReDraw>NewVec.Fonts. By the way, version 2.0 of ReDraw is about to be released, with color as the major new feature. It will use the same fonts as version 1.0. New TEX fonts: The new TEX fonts and their corresponding widths are available at the moment on [Ivy]<AltoFonts>NewTex.Fonts and [Ivy]<AltoFonts>NewTex.Widths. If you want these, pull them fast, since they aren't going to stay there very long. They are out there at the request of Ron Pellar, and I plan to delete them as soon as Ron has pulled them, Lyle 15-JAN-81 11:22:37-PST,785;000000000000 Date: 15 Jan. 1981 11:21 am PST (Thursday) From: Tanner.PA Subject: Revised edition: Recreation Distribution Lists To: PaloAlto↑ cc: Tanner Here are the corrections/additions to the recreation distribution lists I've received so far.
