I got it from my old boss from a project where we built a QA training station for an ultrasonic inspector. My (MACRO-11) code would slice a portion of a large (multi-megabyte) data file and display just the desired component (out of a tray of dozens) on the screen at 1000-pixels-per-inch resolution on a 512x512 screen. It happened that we were manupulating grey scale data, but the framebuffer would do color. The card has three odd LIMO-like connectors for RGB-sync-on-green and that's it. I have one cable (for the green channel, naturally). I have *no* idea if there are drivers for anything aside from RT-11, since that's what I was given for the project. I still have a few listings, and I _may_ have an RL01 and/or RL02 pack with source code. I'd be interestded to see pictures of your framebuffer. Mine is accessible, but not here, so if desired, I could do the same. -ethan

OK. I really can give you an Indy, if that's an incentive, and we're just off the A64, not right in York. -- Pete Peter Turnbull Network Manager University of York

Obscure DOS question

by vcf＠siconic.com

MS-DOS 3.3 has a limit of 512 entries in the root directory. I have a need to put more than this. Was there ever a way to put more than 512 files in the root directory? Some sort of patch or utility? Did previous or subsequent versions of MS-DOS allow more entries in the root? Another question: When using the SUBST command in MS-DOS, you cannot aparently substitute the C: drive. I seem to recall that MS-DOS 6.0 allowed this, although I might be confusing that with the ability of LANtastic to redirect the C: drive to a network drive. At any rate, what I'm trying to do is overcome the limit of 512 file entries in an MS-DOS 3.3 root directory. Does anyone know how to accomplish this?

PDP-8 QBOL or DIBOL

by djg＠drs-c4i.com

Some DIBOL information is in the COS-310 manuals http://www.pdp8.net/pdp8cgi/query_docs/query.pl?Search=cos&stype=Partial+Wo… The COS images under ftp://ftp.pdp8.net/images/ may have some DIBOL/QBOL software. Also probably the ETOS image has some. I probably have more around. If you find you need more email me in two weeks and I may have time to look more.

Server space, SGI O2 drive sled, DEC 3000-300x (Pelican+)

by mokuba＠gmail.com

First off, if anyone ever needs some server space to just dump stuff, I've got about a gig of space I can dish out for files and stuff, and ~15 gigs of b/w a month for usage, over charges are negligable anyway, so feel happy to have fun with whatever you upload (email me for info) Also, I've got an O2 with all sorts of goodies (loaded with ram, analog a/v board, etc) but no drive sled! I check ebay often but (unless I'm doing something stupid) I don't see any. Finally, does anyone have OS (Tru64 or else) that will run on a 3000-300x? It's got 256 megs ram, and two internal 4.3's that I'm not sure will actually work, but I've no way to test, anyone who knows anything about this info I'd love to hear from you. Thanks! -- Gary G.

LaserWriter Plus

Fred Cisin <cisin at xenosoft.com> wrote: > Which sub-model of 4 DOES take the Postscript SIMM? 4Si. I have one, it's one of my favourite printers. 3Si and 4Si are both Canon NX engine, very few differences, but the formatter board is HP, not Canon, and the 4Si one is quite different from the 3Si one. The 3Si one takes discrete ROMs for PostScript and the 4Si one takes a ROM SIMM (I have one in mine of course, since I don't believe in PCL - PostScript forever!). I think this PS ROM SIMM is specific to 4Si and other models using PS ROM SIMMs have different ROMs. MS

Apple LaserWriters and HP LaserJets

by alhartman＠yahoo.com

I remember becoming LaserJet certified in 1989, and after taking the class, 2 other students and I had to break down a LaserJet I and put it back together. The instructor said not to worry, this one was broken and if we just got it back together with all the parts in the right place it would be ok... I was working with one of the Help Desk Girls (non tech), and the guy who managed the parts room (also non-tech). They did all the work as I directed them. We broke it down, put it back together and just for kicks and giggles, started it up... Wouldn't you know it worked perfectly... Needless to say, the three of us were LaserJet authorized a few minutes later... I remember a set of articles in Computer Shopper from a guy (whose name I can't remember) that had a whole website (and in those days, having your own website was no small trick..) about modding LaserJet and LaserJet 500's to take an Apple LaserWriter logic board to convert it into a Laserwriter. I wanted to do one of those SO bad. I ended up with a LaserMaster Printer that was a LaserJet IIP engine with an external controller that went in a PC and did all the PostScript processing in your PC. They called it a 'WinPrinter'. Before that, I used my Atari ST with the MagicSac Mac Emulator (not Mac Plus, Mac 128/512k) using MacOS 6, a program called EpStart (to be able to use an Epson Printer in place of an Imagewriter), and my still working today IBM PC Graphics Printer (an MX-80, IBM branded) to print. My first ever printer was an old Okidata Microline-80, 7 pin DotMatrix that used typewriter ribbons and roll feed paper on my TRS-80 Model I. Those were the days...

Totally OT, but frustrated.....

He made the point that in several decades we've seen hardware get bigger and faster by several orders of magnitude, but software hasn't done anything of the sort. -- Pete Peter Turnbull Network Manager University of York
