The dark blue is actually a switched off cell. I know it sounds backwards, but when I disconnected the video cable once, and only the backlight was on, the whole thing was dark blue. I tried a little program that reverses the color, until something else changes it, and it's actually easier to read (as long as the contrast is set right). It's actually easier to read than some CRT's that I've seen, because the letters aren't fuzzed out at the edges. -- -Jason Willgruber (roblwill(a)usaor.net) ICQ#: 1730318 <http://members.tripod.com/general_1>

Old Microsoft MSX standard?

by rcini＠msn.com

Hello, all: While reading some late-1984 Byte mags, I came across a description of the Microsoft MSX computer standard. Implemented mostly by Japanese computer manufacturers, an MSX computer is CP/M based with 32k of RAM, a cassette port, RF modulator, and cartridge slots for expansion. I picture a Z80-based VIC-20 or C64, although not in that physical form. Anyone have any info on this?

DN3500 motherboard question

by rexstout＠uswest.net

(A copy of this message has also been posted to the following newsgroups: comp.sys.apollo) Got lots of Apollo stuff today, including two 4000's with no CPU chips, two 3010/3000 motherboards and a 3500 motherboard. But for now I have only things bothering me. First, what are the specs on the PC compatibility card and how do I use it? Second, which 3500 board is better, the 11858 or the 15652? What's different between the two? My current 3500 has the 15652 and I'm wondering if I should leave it there or switch the boards. ---------------------------------------------------------------- | http://members.tripod.com/~jrollins/index.html - Computers | | http://www.geocities.com/Area51/Lair/1681/ - Star Trek | | OrHam(a)qth.net list admin KD7BCY | ----------------------------------------------------------------

Virus Checking

by Pjoules1＠cs.com

IIRC it wont even pick up Form A which wasn't even new when MSAV was first released. BTW I wont go into detail but there haave been long discussions about the plural of virus on alt.comp.virus and it seems to come down to the consensus that those who have knowledge of the etymology of the word (and who are generally in the anti virus camp) insist that it is viruses whereas those who think that viruses are 'cool' (and those who write them) insist that it should be viri or the impossible virii.

Old NCR printer

by dann＠greycat.com

Not sure if this is on-topic, but if not, just tell me; I'll go quietly :-) A friend gave me a working (!) NCR6416 laser printer (he was clearing out a shed), and I've got it hooked up to a Linux box on my net. It has some small problems I feel sure I can fix by giving it a thorough cleaning, but my main problem is docs. My friend lost the manuals for the thing long ago, and NCR doesn't seem to remember they made it. I need info on switch settings, front panel switches and indicators, programming, etc. About all I've been able to find is that it uses a toner cartridge type that is still readily available. I can print straight text to it fine from Linux and VMS, but I need to know more to print from OS/2, apparently. *sigh* Need a clue, people; any help *greatly* appreciated.

Fujitsu FW5020M05 and Macintosh System Disks

by todd.osborne＠barnstormer-software.com

Can anyone provide information on a Fujitsu external floppy disk drive for the Mac? It is model number FW5020M05. I am trying to rebuild a SE/30 (10 years old yesterday :) On the same note, anyone know a secret way to take the Mac OS 7.0.1 images that Apple has available on their site for free, download them to a PC and make system disks from them? I have tons of working PC's, but not networkable Macs to use to do this. Or, if anyone can dup me a copy of System 6.0.4 or 7.0.1 I would appreciate it. Apparently this is legal, since Apple has the images on their site, but if it is not, forget I asked :) Todd -- -------------------------------------------------------- Todd Osborne Senior Software Engineer FMStrategies, Inc. http://www.fmstrategies.com/ -------------------------------------------------------- FMStrategies, Inc: tosborne(a)fmstrategies.com Internet E-Mail: todd.osborne(a)barnstormer-software.com -------------------------------------------------------- Founder of the Virtual Windows Class Library (C++) http://www.barnstormer-software.com/vwcl/ -------------------------------------------------------- Anagrams?

Philips P5020 / MICOM (was: Re: "Single instance" machines)

One of >the slots in my machine has a RAM card in it (64K I think). >I know nothing much about it, and I don't have any form of system disk >for it. Well, after I sent the message I began to doubt. Apart from the P5020 there was another computer that looked exactly like the P5020 but had a totally different machine inside. Floppys and screen were the same but the rest wasn't. It did not even have a Z80. I saw them at the computer club. They were called the 'Televerket' and were supposed to be some kind of communica- tions system for a Scandinavian PTT. I think it was also called P5900. The software for it was developed in Forth, so the Forth fans in the club were happy with them. I may have seen the card cage in this machine. You shouldn't have said you didn't have a system disk for your P5020 :) now you made me unearth my own P5020. Or at least try to. This is not an under- taking for the faint of heart. The machine is in my garage. In the back of my garage. The garage has two doors. The one in front that a car is supposed to go through (this has only happened once, in 1986 I believe) and a regular one in the middle for me. Imagine that you take a piece of chalk and attach this to the bottom of this door, at the far end, so when you open the door into the garage you draw a half-circle on the concrete floor. This circle then represents the border of how far you can walk into my garage. So I put on my coveralls, donned my old miners helmet with the strong lamp on the front and I started digging a corridor, by lifting stuff out of the way and putting it back down behind me. Soon the batteries of the lamp began to fade but just at this moment I found my P5040. There was a floppy in the right hand drive. Since this machine is compatible with the P5020 I dug it out quickly and went for the door again. Back onto safe ground I opened the P5040 and saw it had a large PCB on the bottom, and a daughtercard with two eurocard (DIN41612?) connectors for expansion cards, like your P5020, one of which had some kind of communications card in it. After being connected to the mains the machine booted at once. The disk was a CP/M 2.2 disk for the P5020. It had the spreadsheet program on it I mentioned earlier. I found my memory got warped after all those years because it turned out to be the Supercalc 2 program by Sorcim Corp. It claimed to be made for the MICOM 3003. So there you have it: Micom 3003 and P5020 are the same machine. I guess the Micom that Lawrence has is going to be the P2500. I made an image of the CP/M disk with Teledisk and wrote this image to a new disk. The P5040 also booted from this disk, but only if I put it in the right hand drive. This is a bit strange, since when you switch on the machine with no disk in it, the left hand drive lights its led and does a seek. Ah well. I can email you this Teledisk image. You need an AT PC with a 1.2MB floppy drive to write the image to a real disk, since the P5020 uses 80 track single sided drives. You can use a regular 360K disk to write the image on, if it is from a well known brand this will work. Now I'm off to dig out the digital camera so I can put a photo of this thing on my web page, it would be a same to bury it again without a photo after all this trouble :) Kees
