The best way is to convert the GIF into a "portable" bitmap (i.e. nothing but the bits), then back into a GIF again. I've been doing this for a decade with a package called NetPBM: NetPBM, GRAPHICS, Suite of graphic image format manipulation & conversion pgms Enhanced portable bitmap toolkit. The PBMPLUS toolkit allows conversions between image files of different format. By means of using common intermediate formats, only 2 * N conversion filters are required to support N distinct formats, instead of the N**2 which would be required to convert directly between any one format and any other. The package also includes simple tools for manipulating portable bitmaps. As of the last release I built (early 90's), it was supposedly available at: * wuarchive.wustl.edu (128.252.135.4), directory /graphics/graphics/packages/NetPBM * ikaros.fysik4.kth.se (130.237.35.2), directory /pub/netpbm. * ftp.informatik.uni-oldenburg.de (134.106.1.9). This site also carries binaries for the Amiga. * peipa.essex.ac.uk (155.245.115.161), directory ipa/src/manip * ftp.rahul.net (192.160.13.1), directory /pub/davidsen/source * ftp.cs.ubc.ca, directory /ftp/archive/netpbm What *I* like about NetPBM is that it's a command-line tool, not a "point-and-drool" graphics tool. This means that when I have a few thousand images to convert (as I just did yesterday) that I can do them all with a command script. I especially like it for things like auto-cropping and twiddling colormaps to make backgrounds be "transparent". -- Tim Shoppa Email: shoppa(a)trailing-edge.com Trailing Edge Technology WWW: http://www.trailing-edge.com/ 7328 Bradley Blvd Voice: 301-767-5917 Bethesda, MD, USA 20817 Fax: 301-767-5927

HP9114B battery pack

by allisonp＠world.std.com

<It's supposed to be a Panasonic 'block' type battery. A similar battery <was used in the Portable+, and the service manual for that machine <clearly shows an assembly of 3 Cyclon cells. So it looks like either <could be used. The difference is they are both gelled electrolyte lead acid cells, No difference. Therefor the working voltages and charing conditions will be very similar. SCR based chargers like that will not work if the cells are open circuit or sulphated (high resistance failure). Allison

I found an HP150 (model 45851A?)--how do I make it work?

By the time of the Touchscreen II, lots of us who had deployed 150A/Bs had concluded that while the 150 wasn't that bad, touch screens were not all that they were cracked up to be. You had to take a hand off the keyboard and reach up and touch the screen, and if you had to do this a lot it resulted in a sort of fatigue that was called "gorilla arm", and there were usually ways to do what you wanted from the keyboard (either a function key or tab around some and then press a function key or Enter). So most users didn't bother with it after the novelty wore off. So when it became an extra-cost option we really couldn't see paying for it. Besides, who wants a bunch of fingertip-sized smudges on the screen? -Frank McConnell

Diode help... HELP!

<Well, the obvious chip to use for this application would be an 8-input <priority encoder like the 74x148. I have no idea if there was ever a 3.3V <version of this chip, though. No there wasn't, t was never that commonly used. As to a chip to do what a simple diode encoder can do is beyond me. Allison

Archive Viper Data Cartridge Drive - Available for cost of shippi ng

by jdykstra＠nortelnetworks.com

I've got an Archive "Viper" 150 MB. data cartridge drive with SCSI interface, model 2150S, available to the first responder for the cost of shipping. The drive worked the last time I used it (several years ago), but there's no warranty. The belt, heads and capstan are unworn and appear in good condition. This is the drive only--no enclosure or power supply. If you want them, I also have seven data cartridges. Althrough they physically fit this drive, they may not all be accepted by the drive's firmware--I have a half memory that certain drives only worked with certain cartridges. If you want this drive and the cartridges, email me your address, desired method of shipping, and whether you want the cartridges. If I don't hear anything by Wednesday, it goes up on eBay. ---- John Dykstra jdykstra(a)nortelnetworks.com Principal Software Architect voice: +1 651 415-1604 Nortel Networks fax: +1 612 932-8549

In einer eMail vom 2/23/100 3:39:04AM, schreiben Sie: << Uh, you don't think they'd let me take this on the plane as carry-on luggage, huh? I'm going to be in SF on Monday for work... >> According to my experience, shipping this beast would be around US$ 1000,- (within US or to Europe, not counting forwarding within Europe). Not too bad for a solid item like this, I believe. John G. Zabolitzy Munich, Germany

Two VMS software tapes available

by af-list＠wfi-inc.com

I finally built a rack for my 9track tapes and went through them all. In addition to what looks like an entire software distribution for my (still dead) Cadnetix system, I found two VMS tapes, available to anyone interested: XDS-11 Base Package Signetics' Amaze Rev.C Binary (must be an *ancient* version of this, marked 1985) Cheers, Aaron

<Sounds like a job for an IC, like 8 bit parallel to serial using one dip <switch input for serial data perhaps clocked by sequential reads. Maybe a <bit binary to octal? 8 bit multiplexer? He wants to do a diode encode for three switches 8 possible states. The reverse would be to decode two bits to sense the state of three switches to be read on a single bit port. <Sheesh, I shudder to think how many pens are busy on the backs of envelope <right now. Only to show what's in my memory. :) That is a textbook circuit. Allison
