Microsoft ICE for compositing scans: a success story

by legalize＠xmission.com

On my final trip to The Black Hole, I picked up some more Tektronix documentation. One of these was a photocopy of the manual for the 4953/4954 Graphics Tablet. This manual combines the instruction and service manual in one with circuit diagrams and descriptions in the back of the manual. However, since this was a photocopy and not an original, the circuit diagrams were not available in their original size. The person who photocopied the manual had attempted to cover the diagrams with multiple photocopies of different parts of the oversize page. It was difficult to manually match up the different pages, if only just to identify the order in which they should appear in a scanned PDF of the manual. Instead I just fed the scans into Microsoft ICE, available as a free download: Microsoft ICE (Image Composite Editor) <http://research.microsoft.com/en-us/um/redmond/groups/ivm/ice/> The results speak for themselves. See the last three pages of the resulting PDF: <http://bitsavers.trailing-edge.com/pdf/tektronix/49xx/070-1791-01_4953_4954…> You can see that the person who photocopied the manual did miss a few bits of the schematics, but for the most part the schematic is now legible as a single diagram. Due to the blending that occurs at the edges of the individual images, Microsoft ICE will sometimes produce a grayscale image from the bilevel scans I use for making PDFs of manuals. So a little post processing in ImageMagick reduced the bit depth back down to 1 bit per pixel and converted the image to PDF for combining with the rest of the pages via pdftk. The command stream went roughly like this: convert composite.tif -monochrome -compression Group4 page.tif convert page.tif -density 600x600 page.pdf The -density argument tells the PDF file that the image was scanned at 600 dpi so that the composite page is shown at the same relative size to the other pages in a PDF viewer. It may be possible to combine these two commands into a single invocation of ImageMagick with identical results; I haven't tried that. I had previously used hugin, an open source image compositing program that has tutorials for compositing multiple scans like this. However, using hugin to do the same job was a very tedious, laborious and lengthy process. With MS ICE, it was a simple matter of drag-n-drop of the image files onto the application which it processed automatically to find the resulting composite. -- "The Direct3D Graphics Pipeline" free book <http://tinyurl.com/d3d-pipeline> The Computer Graphics Museum <http://computergraphicsmuseum.org> The Terminals Wiki <http://terminals.classiccmp.org> Legalize Adulthood!

Missing footnotes [was RE: Our Museum Need a special help..]

by RichA＠vulcan.com

From: Rich Alderson Sent: Wednesday, October 10, 2012 11:40 AM > The earliest Buddhist texts are written in a Middle Indic[2] language Oh, crap. There was only going to be 1 footnote anyway, which I forgot to include: [1] "Middle Indic" is a designation for the Indo-Aryan[2] languages of the period roughly between 500 BCE and 800 CE, descended from Old Indic languages contemporaneous with Vedic, Epic Sanskrit, and Classical Sanskrit. The Modern Indic languages are descended from various of the Middle Indic languages. [2] This is a linguistic classification, prior to the racialist adoption of the word "Aryan" to mean something entirely different. I decided in composing the 1st note that the 2nd was needed.

He's obviously building a 21.6 Gigabyte RAID Array using a proven storage medium with a long track record, rather than these modern hocus-pocus terabyte drives that use pure magic to record anything and you never know where on the media it will actually land. Won't hold all of bitsavers by any means, but will hold like an eighth of it. 15000 floppies, times 1.44 Mbyte each, gives 21.6 Gigabytes. Oh, wait, he needs at least one drive for redundancy. Actual capacity = 14999 * 1.44 Mbytes. The 15000th drive carries the parity stripe, just in case any of the other drives ever fail. Tim.

WATFOR for IBM 7040

by spedraja＠gmail.com

Hello. Im' playing actually with diverse emulators for the IBM 709x and the software available for them (IBSYS and CTSS). Fun and instructive (I'm using it to play with COBOL and FORTRAN at present). Now I should like to go one step beyond. I have doubts about the compatibility but I should like to know if exists some request for the WATFOR compiler for the IBM 7040 to the Waterloo University or whoever would be the owner of the rights of this software.. -- Gracias | Regards Saludos - Greetings - Freundliche Gr??e - Salutations -- Sergio Pedraja twitter: @sergio_pedraja ----- No crea todo lo que ve, ni crea que est? vi?ndolo todo

I stand embarrassingly corrected TWICE! The "wrong" Mike part is explainable in that I get cctalk as a digest and messed up in the Copy & Paste. The second part was me reading "control console" and assuming you meant the teleprinter. So Sorry! I spent a lot of time with a B2700 learning Fortran. The Glendale, CA Board of Ed had a B2700 that was used by the Junior college for Cobol/Fortran classes back in the mid-70s. A buddy from High School got a job there as a Sys Admin so got to spend a fair amount of time around it. Eventually they upgraded to a B6800 system. Eventually I went to work in Goleta on the Small systems, then got transferred to Pasadena where the Medium systems were built. I was there as they were debugging the B2900. ;-) Very fond memories.

[...] To complicate > things a bit this was part of a LVM raid ext3 raid 5 set, When you have a drive go bad in a RAID 5, it's best to pull the drive, put a new one in its place, and start a rebuild. That's the point of using RAID 5. Trying to recover data from the failing drive is mostly a waste of time. Of course, if the drive wasn't in a RAID 5, mirror, etc., you wouldn't have that option. My experience is that once it starts it just gets worse, especially with the newer drives (>100 or so GB) - junk the drive and put a new one in. In fact, based on what I've seen and heard I'd replace more of the drives once you get the bad drive replaced and the array rebuilt, especially if the drives are from the same batch. Marginal drives can and do go out during rebuilds. Of course, if the data on the array isn't critical then this becomes much more flexible- but if it is then you don't want to have your second drive go at some point in the near future, then the third give up while you're attempting to rebuild the array after the second disk's failure. Any reason you're recovering data from the drive rather than rebuilding? I'd go along with Eric here - if you rebuild then you're starting with a known-good array, rather than potentially having errors in your replacement drive. This isn't just anecdotes, either - I've seen numbers. That's one reason I've gone to mirrors on my few critical installations.

That's part of why I went with Innerduct - I'd worked with it in a commercial setting and was able to buy 100' off the reel at a local Granger's supply. If I were trying large PVC conduit in a short basement, I'd also consider a joint in the middle, but it seems that you worked it all out. > I was just lucky enough that the folks who had rehabbed the house > back in the '80s and added an HVAC system had left extra space > around the old chimney when they put in the duct work (and also > lucky that said space intersected my office).

I had the same advantage in my 85-yro house (now 98-yro!) - next to the stackpipe is a laundry chute from the bathroom to the basement. The back bedroom shared a wall with that, and there was room around it to run the innerduct. I did have to rip a large hole in the bedroom wall to mount the various duplex boxes since it wasn't easy to find larger low-voltage boxes. Now, I can goe to Lowe's and get the big orange plastic wall boxes that even directly accept (with concentric breakouts) 1" and larger conduit. If I ever build a house, I'm going to run innerduct all over the place. The stuff is really handy to work with (and comes with pull-rope/tape already installed). It's specifically designed for fiber, but there's no problem sharing the space with twisted pair low-voltage cables. -ethan

disk flaws, classic vs. modern

by jws＠jwsss.com

I have a problem that cropped up that spans both old systems and flaw maps / disks that have flaws to skip over and current technology. In the old days with my experience on a lot of cdc winchesters and removable pack smd drives (and trident) there were flaw maps you could use in a controller to figure out where the bad spots were. When shipped from the factory the mmd / cmd / emd / fsd drives (at least the first two) were not allowed to have more than a false address mark on a track, and a limit of maybe 5 for the entire stack. Later at least on the mmd's they had run of marginal media and upped the FAM errors considerably. (10? 15? don't recall). I later found some drives delivered to such as Datapoint for large systems delivered when we got the story about the FAM problem (needing to up the count) that had zero flaws, but that was 10 years later buying some scrap drives (better than the ones I had purchased 10 years before, still working). Anyway, recently I had a system with a 1.5tb seagate grow a count of "uncorrectable offline sector count" errors. I'm telling this up front since these are effectively the same as the above errors, sectors that are not recoverable by the drive and presented as bad or timeout spots when you seek to the sectors. The errors were not there when I initialized the linux system on the drive, and grew later. To complicate things a bit this was part of a LVM raid ext3 raid 5 set, so there are other complications here, but the initial build was flawless, ran about a 6 months then this drive grew 16 bad errors visible to linux. So, I have now got the situation where there is a bad spot in a file (more complicated because this is part of a raid set, but bear with me). If you power cycle the drive set they do a scan of the media with the raid system I'm using (linux based) and hang before releasing it for server operations. That is the only flaw that there was, and I had a brick. Thank heaven I could put it in a desktop system and recover the data (7tb of it). Anyway, have we lost the capability with such as Linux to run with flaws growing on media at the level where transfers from media come from the drive target to the host, or did this vendor of raid equipment (appliance was readynas nv2+) have a flaw in their bringup procedure. I am glad I shopped and got a system with raid 5 support like this with a linux system that I could take out and troubleshoot with any linux tools, rather than hardware raid. Dodged that bullet. but I am disappointed even so with the behavior of the raid set when I put it on my recovery system. I think there is a basic loss of what one would have been accustomed to in earlier times with media, throwing their hands up with defective media. I was only able to narrow down the error with manual applications of careful dd commands and shell scripting (lacking a better tool) to see the errors. There is a nice timesaving web page if you hunt around the pages found by searching for smart errors. At least that is a nice tool, telling a lot about the drive. I am not going into why a 1.5tb drive with huge amounts of extra space (as I understand it probably > 500gb) can't reassign media 16 consecutive sectors, as that is a totally different discussion.

disk flaws, classic vs modern

Well, I lose anything since the last backup, but given that those >happen every 24 hours, it's not *that* much data and I can reconstruct >it pretty easily. Guess it depends on (a) whether it's personal or business and (b) (if (a) is business), how good your secretary is. I'd rather replace the disks than spend hours dealing with people who come in grumbling about their work for today disappearing. Also, for most non-miniscule businesses it's cheaper to replace the drives preemptively than it is to pay for people to recreate the work done since the last backup if more drives fail.

Fwd: [AHCS] NorthStar Horizon Boot Disks

by david＠classiccomputing.com

Can anyone help my friend Kyle out? Please email him directly - kylevowen at gmail.com > I'm trying to revive a N* Horizon, and as I've found out, you have to have a booting machine to make boot disks. In order to have a booting machine, you either need a boot disk or a ROM board. My processor board doesn't have a ROM option, so I'm out of luck. I have supposedly 4 boot disks, but none of these seem to get the computer booting, though I hear the drive head move back and forth as it seems to read the disk. I still don't get any output into the right serial port. > > Does anyone have access to a bootable Horizon? I have a few hard sector floppies, so if I could get a boot disk copied, that'd be great. Optimally, I'd like to try to read these disks on a known working machine before having to overwrite any. Two aren't labeled, so they may very well be blank. All of the others have labels indicating some possibly neat programs, like Microstat, WordStar, and Mailing List Utility. About half of the disks are labeled Care. Care System, Care Data, Care Source Code, and so on. Any idea what the Care System could be? Another one is from Validata Computer and Research Corporation, which apparently is still alive an well in Montgomery, AL. It's entitled "5 Meg Hard Disk Start Up Diskette for Worcs, PM, Care Systems". No telling, eh? > > My system has a CompuPro 24k SRAM card (with only 20k populated), a N* RAM16-A3 16k RAM card (fully populated), a N* ZPB-A2 processor card (no ROM option) and a N* MDS-AD3 double density floppy controller, all on a N* HRZ-MB-3 motherboard.

3.5" drives needed...

by geneb＠deltasoft.com

I'm working on a project to add 3.5" high-density drives to my Kaypro in order to use DSDD media with them. I chose HD drives because getting genuine DSDD 3.5 drives for anything resembling a reasonable price is basically impossible. It turns out that I don't have any 3.5" drives in my stash any longer. If you've got a pair of working 3.5" drives with drive select jumpers, I'd like to hear from you if you want to sell them.

Which vax-vms license for a microvax II with VCB-02?

I figured I would just need a workstation license, but this doesn't seem to have worked. > > Older KA-630 boards (maybe all of them) do not have the firmware to talk to the VCB-02 screen during boot. So, you have to use a serial console to check boot progress or run diags, etc. Once it is booted, VMS 4.7 will run the VCB-02 just fine. There were single-user licenses and multi-user ones. The license exceeded message sounds like it has to do with the single/multi user issue, not the VCB-02. I think maybe there is a system boot-time switch to select # of users, and if that doesn't match, then only the administrator is allowed to log in. (Been so long since I ran VMS, I'm forgetting a lot!) I bought a MicroVAX-II board in 1986, and ran it as a home computer for about 21 years, until the hard drive died. I added a VCB-01 first, then upgraded to a VCB-02. Jon

You could list the many other Individual Computers products, mostly made for the Amiga (accelerators, memory cards, graphics adapters, etc.), or the 1541 Ultimate and Ultimate II, or a myriad of others. It might be interesting to link all of this stuff from a wiki (maybe Vintage Computer Forums' wiki?). There are, however, many fewer kits available. I'd love to see more, as I feel differently about a machine that I have built, myself. - Alex

Anyone want some CR-563-B CD drives?

by fraveydank＠gmail.com

Hey all, These are a sorta-proprietary Panasonic interface CD drive that was found on a number of PC ISA sound cards. I have a pair of them and possibly the sound cards to control them (though I have an inclination to hold on to those for personal reasons). I realize this is teetering dangerously on the edge of "crappy '90s PCs" rather than true classic computing, but one man's trash is another man's treasure (unless it was made by Packard Bell). Free if you'll pay shipping. I owe some people some FileMaker boxes, and I haven't forgotten, but it's been at the back of my queue. - Dave

Serial Connection for UVax II with H8571-B

by tpresence＠hotmail.com

Hey guys and gals, I have tried and failed to get a successful connection between my uvax II and a pc rs-232 serial port. The H8751-B didn't seem to work, so I pulled it off and wired my own MMJ-DB9 connector. I have tested the MMJ cable, and it works flawlessly. For my connectors I have followed "The Cable" documentation at http://www.mcmanis.com/chuck/computers/vaxen/panels.htm (chucks house of vax), under "The MicroVAX II" section but it hasn't helped. I have tested the MMJ-DB9 connection from my uvax III consoles and from the microvax 3100 and it works fine, so I think the PC side is working correctly. The MMJ-DB9 on the pc side is DB-9 Pin Color Purpose 1 Pin 4 & 6 2 Yellow Transmit 3 Black Receive 4 Pin 1 & 6 5 Red Signal GND 6 Pin 1 & 4 7 N/A 8 N/A 9 N/A When I toned out the H8571-B connector and this is what it toned out to (using a straight MMJ cable out of the connector: H8571-B Pinout DB-9 Pin Color Purpose 1 N/A 2 Black Transmit (Tx+) 3 Yellow Receive (Rx+) 4 White DSR 5 N/A 6 Blue DTR 7 Red Transmit Ground (Tx-) 8 Pin 8 9 Pin 9 Any idea what pinouts I should use for the H8671-B -> PC connector cable should be?

semi-OT: alternatives to common e-mail services

by rampaginggreenhulk＠yahoo.com

Are there any? Of course they are limitless, for instance asking a comrade access to their server space. But barring any of that, is there any available for a modest or no fee? I hear the commercial for reagan.com, and besides the fact that I refuse to participate in the growing Reagan cult (have ample respect for the man, but please), and I'd, right now, rather not shell out 40$ a year. ?Oh I forgot, I have my own domain (indiscreetlogic.com), but haven't had the time or inclination to muss with ? it. Is there an alternative to the demoniac Yahoo!, Hotmail, Gmail in the interim? I wish to, if at all possible, avoid having my e-mails scanned (like that isn't going to happen), or having to inadvertently support causes and movements that will ultimately subjugate humanity, promote aberrant anti-social behavior, bolster the Federal Reserve, the Tri-Lateral Commission, the rise of the Anti-Christ, etc. etc. I love kittens too. No funds should be funneled into organization that fail to support the advancement, emancipation, and general well being of kittens. And honey badgers.

I'm nowhere near as useful as most of the folks on the list, but I think of the list and its archive as an incredible resource to help out anyone interested in this hobby - of whom there are not (in my opinion) enough, and anything we can do to encourage more is a good idea. Informative posts from e.g. Tony (how do I disassemble this monitor, and where am I likely to get a nasty surprise if uninitiated?) or Fred (what's the format of this floppy that I need to read likely to be?) look to me like the essence of the list, and the quicker they are accessible to the more people, the better. If indexing helps facilitate that, right on. If indexing make me think twice about my posts, well, that may well be a good thing too. I clearly recall a post where I gave the resistor color-code *wrong* (!) because I typed way faster than I thought (and I don't type that fast...); could be if I'd remembered people might pick my post up on a google search, I'd have been a bit more careful. -- - Mark 210-379-4635 ----------------------------------------------------------------------- Large Asteroids headed toward planets inhabited by beings that don't have technology adequate to stop them: Think of it as Evolution in Fast-Forward.

Old UNIX utils

by alexeyt＠freeshell.org

I saw a lightning talk on Tursday by one of the maintainers of SmartOS, a fork of Illumos, itself a fork of OpenSolaris. He recently discovered that there were some interesting things in /usr/bin that most people don't realize are there, that had stowed away unnoticed over the years: bfs and ta. He demoed them for us, and I have to say I'm sort-of shocked that they never got rm(1)ed. Does anyone here remember using these when they were new/actually useful? And speaking of ta, the presenter wasn't sure how you're supposed to drive it - it is supposedly 'like troff -a' but no matter what input he gave it (man page sources mostly), all he ever got out of it is 'unknown input character blah'.

Tektronix CT8500 terminal -- is it an OEM'ed Tek 4024?

by legalize＠xmission.com

One of the items I pulled out of the Black Hole this weekend was a Tektronix CT8500 terminal. It goes with their 85x0 microprocessor development systems that we've talked about here over the past year. I also snarfed the operator's manual for it, so that will appear on bitsavers soon. Bitsavers has the user's guide for the CT8100 terminal which is really a 4023 as is blatantly obvious from reading the manual. However, the operator's guide to the CT8500 doesn't make mention of any other Tektronix terminal model. On Wednesday, I'll open the cabinet and inspect the board set inside, but until then I thought someone here might be able to shed more light on this. -- "The Direct3D Graphics Pipeline" free book <http://tinyurl.com/d3d-pipeline> The Computer Graphics Museum <http://computergraphicsmuseum.org> The Terminals Wiki <http://terminals.classiccmp.org> Legalize Adulthood!

EISA Configuration Utility and .CFG files

The challenge with EISA is finding the .CFG files that work with the EISA Configuration Utility so you can get the mainboard to work with the boards. The floppy-based sets I have come across are a superset of those needed for a specific board so it is usually worth digging around in manufacturer "driver"/mainboard diskettes to check if they also shipped .CFG files for boards other than their own. The .CFG files (they are text files sometimes with comments) can be a useful source of information about what the board does and how it is intended to work (like slot-specific assignment, IRQ conflicts etc).

Microwave sink (was: Re: strange remark about your collection?)

This may not be the best idea, unless your water is "dirty" (in the sense of having something suspended that forms nucleation sites for steam bubbles). Our water is "clean", and my wife once decided to try to heat some up in our microwave. It superheated by a noticeable amount, then finally boiled off catastrophically. Big cloud of steam, microwave door blown open, loud noise, 100 C water splashing around the kitchen. There was some damage apparent later in the switch that should normally turn the thing off when the door is open, which I eventually had to replace, but otherwise the microwave itself was OK. Maybe this is an unusual event and almost certainly it depends on what container the water is in, but I'd use a little caution with that approach given our experience. Howzabout a pile of CD's or marshmallows or a crate of eggs in there instead? ;-) OK seriously, wet towel or wheel of cheese in a bowl or something that won't superheat and has not much mechanical integrity?

Getting Data I/O Promlink to talk to a System 19 programmer

Hi all -- Anyone have any experience getting Data I/O's Promlink software (I have 2.6, 3.4, and 6.1) to talk to a System 19 programmer? I've read through the documentation on Bitsavers but it doesn't mention Promlink at all (it's possible that it predates the software completely). Promlink says it supports the System 19, and I've configured everything (baud rate, etc) on both ends but I don't know the magic incantation to use on the 19's panel to make it talk. Thanks, Josh

Kaypro II

A fellow has a Kaypro II here he wants an offer on. There are manuals and a modem, cables, works, floppies and high expectations. Any idea what to offer him? I see numbers from 50 to 600 on epay, but figure this is a the low end. He was asking 400, and is possibly the first owner. If I find out it is an estate sell out I can probably handle it, but if it is an original owner, I figure i should have a good idea what to offer with some backing. any discussion appreciated. It looks like it has has booted and run cpm from one of the screens full of stuff. jim

misidentification of Nixie tubes

(It might require some > circuit redesign, as I suspect it means using higher voltages....) OK, I have started the clock. Shall we place bets on when someone digs up real Burroughs Nixie that glows green? In the electron tube collecting world, weird "never" types are always popping up. Just the other day, someone discovered one instance of this (specifically, a type 41 from Speed that is not the same as the industry standard 41), and stumped the experts. So, it would not surprise me if Burroughs made some Nixies, perhaps as custom devices, low-runners, or even just lab animals, filled with a krypton-neon mix (yes, green). -- Will

microdata beginnings

by jwest＠classiccmp.org

Started prepping the Microdata for restoration tonight. The cpu, mag tape, and front panel are in very good condition. The power supply - not so much. It was apparently a long term home for mice. I don't see any chewed wiring - suprising - but their leavings induced a lot of corrosion and rust. I'm gonna bet those batteries aren't holding a charge. No power applied yet, going to go through the power supply with a fine tooth comb first. I thought the box was an M1600 for some reason, but it appears to be an R4510. Many years ago I did own two M1600's, and this box seems extremely similar, but the front panel is more reminiscent of the Reality Royale rather than the M1600. I haven't located all the stuff that came in the haul, but enough to get started in any case. The power supply is Microdata A20014662-002. Dare I ask.... any schematics? CPU info: Backplane - 19 Connector A20001279 rev a Slot 1 - 8k rom maintenance interface A20001281-001 rev H Slot 2 - control A20001273 rev E Slot 3 - data A20001043 rev K Slot 4 - empty Slot 5 - memory array board CS20002234 rev D Slot 6 & 7 empty Slot 8 - memory control A20002241 rev F Slot 9 - Formatted MTU control A20001274 rev G Slot 10 - Microcomputer Systems Corp CS20002991 rev B (disk) Slot 11 - 8way A20002615 rev J Slot 12 - GPBIO A20002510 Slot 13 - 19 empty It's been over 30 years since I had my hands inside the guts of a Microdata Reality. Brings back lots of memories. I've got the power supply pulled out and on a bench, all the cabinet panels removed, and cpu cables marked & removed. Haven't dug the Reflex I drive out of storage yet. There's also a box of serial number proms :) Pictures are at www.ezwind.net/microdata Game on :) J

TRS-DOS as possible prior art for MS patent on exFAT, and Reference request

by eric＠brouhaha.com

Microsoft introduced a new "exFAT" file system a few years ago, and I wouldn't care about it in the least, except that it is now the official filesystem for SD-XC cards. I only care about that in that digital cameras and such will likely only support exFAT on SD-XC cards, and I'd like my computer, not running Windows, to be able to efficiently access files on such cards. The problem is that Microsoft filed several patent applications covering exFAT. One of them is application US 2009/0164440 A1, for which the US patent office has recently mailed a "Notice of Allowance", which means that they have decided to issue the patent. This application is titled "Quick filename lookup using name hash". Based on the title, it sounded like they are doing what TRS-DOS 2.0 did back in 1978, which is putting on the disk a hash table of filenames which then refer to directory entries. TRS-DOS did that so that it usually only needed to read two sectors to look up a file, the HIT (Hash Index Table) sector, and the actual directory sector containing the file's directory entry. Otherwise they might have had to read multiple directory sectors to find the file if it existed, and all of the directory sectors if it did not. The claims of the patent are a little difficult to interpret. They refer to "a first one or more computer readable storage media having computer executable instructions...". This is basically referring to the disk/flash/etc. the operating system is booted from. They refer to "a second one or more..." which is the disk/flash/etc. which holds the file system in question. Here's are two of the independent claims: 1. A first one or more computer readable storage media having computer executable instructions that, when executed on at least one processor, configure the at least one processor to perform a method of detecting if a target file name exists on a second one or more computer readable storage media, the method comprising: (A) determining a name hash from the target name; (B) determining if the name hash corresponds to a directory entry set name hash value, the directory entry set name hash value corresponding to one of a plurality of directory entry sets, each of the plurality of directory entry sets stored on the second one or more computer readable storage media; (C) determining if the target name matches a directory entry set name corresponding to the one of the plurality of directory entry sets after step (B) determines the name hash corresponds to the directory entry set name hash value; and (D) indicating that the target name exists after step (C) determines the target name matches the directory entry set name. 19. A method of detecting if a target file name exists, the method executing on one or more processors, the method comprising: (A) determining a file name hash from the target file name; (B) determining if the file name hash corresponds to a directory entry hash value, the directory entry hash value corresponding to one of a plurality of directory entries; (C) determining if the target file name matches a file name, the file name corresponding to the one of the plurality of directory entries after step (B) determines the file name hash corresponds to the directory entry hash value; and (D) indicating that the target file name exists after step (C) determines the target file name matches the file name corresponding to the one of the plurality of directory entries. These seem to be to be to be *exactly* what TRS-DOS 2.0 did as early as 1978, so it seems possible that TRS-DOS could be used as prior art to invalidate at least these independent claims, and quite possibly some of the dependent claims as well. So my question is, are there any published works documenting the TRS-DOS file system on-disk format, especially the use of the HIT table, other than "TRS-80 Disk and Other Mysteries" by H. C. Pennington?

Beware of eBay id TRIPLEHAATA

by rampaginggreenhulk＠yahoo.com

He keeps e-mailing me and asking me to pull key tops off of keyboards. NO intention of actually buying a k/b mind you (not at the price I'm asking for one, priced _not_ to sell ;). Beware of this guy, he's simply up to no good! You'll try and be nice and wind up RUINING a keyboard. What chutzpah! ?And relative to a recent thread, YES he does collect keyboards ;)

by pontus＠update.uu.se

Hi A fellow over at the SGI forums has run into some problems and need to let go of his entire collection pretty fast. http://forums.nekochan.net/viewtopic.php?f=4&t=16726942 I don't know the story, I don't know him outside of the forums but there are some really nice machines (even DEC) in there for a person with some storage space and a big car. Regards, Pontus.

Microdata Reality M1600

by jwest＠classiccmp.org

I'm pondering starting the restoration project for the M1600. One thing concerns me though, I have fairly high suspicion that the Reflex I drive is "beyond all recall". Before I put a lot of time in starting that project, anyone have a spare Reflex I drive around just in case I get to that point and it's not recoverable? I'd hate to spend all the time on the machine and find out it's unusable. Unlike a lot of other machines, the M1600 is a paperweight without a disc drive....

I am against breaking up a good keyboard, and only was interested if it was going to be scrapped! Gary
