Yellowing may be irreversible. I've been thinking of removing all electronics from a case, and soaking it in dilute bleach solution overnight. I did find a great method for removing permanent marker from textured plastic. Cameo copper cleaner powder works great and doesn't harm the texture. For other stains, I use a Scotch Brite pad of the type that says it's safe on fiberglass. I'd sure like to find a good method for cleaning keyboards.

How to read/write TRS-80 diskettes from PC?

by kaikal＠MICROSOFT.com

Does anyone know how to read/write TRS-80 Model I format diskettes with a PC? I have a CompatiCard II and a Copy II Option Board. I assume the Option Board is able to copy TRS-80 diskettes (I hope, just got it this weekend and haven't tried yet) but I need to actually write files. Sydex 22Disk appears to support only CP/M formats. Any ideas? thanks Kai

Buzzing PS?

by ds_spenc＠alcor.concordia.ca

Hi, The Apple /// I picked up last weekend has one annoying flaw, and that is a *very* loud power supply, that seems to get louder the longer the machine is powered up. I think this thing becomes even louder than our 1950s-era Westinghouse refrigerator. (OK, perhaps an exaggeration, but the sound seems to carry farther.) There is nothing obviously functionally wrong with the computer - it boots up fine, there's no wavering or glitching in the display, nothing to say that something might be wrong. Except the buzzing. It makes me nervous. Is this noise normal, or is it a sign that something is about to go kablooie? And if something's wrong, is there any way of knowing which part is about to go? It looks like the power supply should be easy to repair, but I don't know what I'm doing with these things. I know it's been stated here that power supplies should be checked before powering anything up, but I don't really know how to do that, and sometimes I'm just too impatient to see my new toys running.

Cleaning boards/keyboards

by allisonp＠world.std.com

> Bill mentions sticking a keyboard in a dishwasher. Bill, I assume you've > done this, and it's OK? I would think that with the heat of drying and > all it would kill the components. Over the years I've done this to de-crud boards, keyboards and equipment dropped in salt water. Water generally will not harm electronics save for stuff made of paper liek speakers. The real problem is insuring it is completely dry after cleaning. A warm, under 180F oven works for this. Removing keycaps and the like first is a good thing. Also some keyboards by their contruction will trap water if it gets in and baking it out is the only way short of sometimes destructive disassembly. FYI, water gets coffee out the best if there ie a small amout of soap to break surface tension. Try to use soaps that are not chemically active and corrosion forming. Woolite is good in the sink for this and most dishwasher soaps are ok. Logic boards like DEC modules, motherboards and the like clean well in the dishwasher. I've done boards in the sink with a soft bristle brush and woolite and dried them by blotting with several paper towels and oven dry. The sometimes look better than new. Remember (not a joke!) Rinse well when doing this. FYI: resist the temptation to vacuum as the moving air can cause static charges that can do subtle and long term damage to ICs, even ttl. Dishwasing is actually safer.

old hardware

by foxvideo＠mail.wincom.net

Last fall I was given the remains of something(?) from a local municipal office. It has been in my garage all winter, and since our Canadian weather has finally warmed up a bit, I went out to have a look. The only identification that I can reach is on the two drives which are a few hundred pounds each and are Century Data Systems Model T80 A's. Can anyone tell me anything about them? There is also another rack about the same size, but it is buried in other junk and is not accessable. The deal also included a Calcomp 1041 plotter which runs the test plot, but doesn't want to talk to my Windows 95/486. Regards Charlie Fox

I'f I remember correctly there was a "Keypad" that allowed you to enter BASIC code and a BASIC language cartridge. Seems I found the cartridge at a garage sale and used to have one, but could never find a working keypad. I have now abandoned the 2600 years ago in an attempt to get rid of some the toys I never "play" with anymore. I find myself re-buying many of the things i've sold.

But since I'd had the technico board for a few years before the TI99 I'd been into assembler. The TI9900 cpu is a bit slow as it was very memory intensive (registers AKA workspace was an allocated block of ram). IT was a real computer archetecture compared to the 8080. When compared to z80 at 2.5mhz or faster it was slower. But that was the spped they could get out of silicon and the ti99 tried to cost reduce it by narrowing the bus slowing it further. Still in many other ways it was a more sophisticated cpu with memory banking when that was rarely heard of. Allison

I'm fairly new to the list, so I'd like to introduce myself (and my computers). I am typing this message right now on an Apple IIGS. I've worked with most of the older Apple II series computers also. I still actively use my Apple IIGS for nearly every task that most people think requires a "new" computer. My first computer, on which I learned a *lot* about programming, was the Mattel Aquarius, which I still own. I've been looking off and on for information about it. The FAQ is nice, but I know of at least one possible inaccuracy: the "Chess" game was released, I'm reasonably sure, because I have it. The computer's not too bad of a player, either, if I remember (it's been *years* since I've used the machine - I'm living at college right now, and the Aquarius is at home). I know now that a lot of people didn't like the Aquarius. I thought it was a really neat machine. I probably learned more from it that from any other single learning tool I've ever had, with the *possible* exception of my IIGS. I'm looking forward to hearing about anyone else's experiences with the Aquarius (or even the IIGS, though info about that is still plentiful on comp.sys.apple2). -- Andy Brobston brobstona(a)wartburg.edu http://www.wartburg.edu/personalPages/BrobstonA/home.html My opinions do not necessarily reflect the opinions of Wartburg College as a whole.

I have been trying to decide the best way to get images into digital form. Naturally, a digital camera is one way, but not the only. There's also the photo/scanner method, camcorder/video capture, and probably others. As I see it, the pros/cons are: DigCam: + Easy to use, convenient - Expensive to buy, somewhat limited capacity, no hard copy of images (except printer output) Photo/Scanner: + Hard Copy, can be used for other stuff too - Film and Developing can be expensive, takes time Camcorder: + Easy to use, Allows for selecting the right image from several views - Video capture hardware/software isn't cheap So, does anyone have thoughts on which is best? I'd like a scanner for other things, but they're expensive too. There's also the question of 35mm vs. polaroid and type of scanner. (Not to mention where the heck would I put it!) I've got a camcorder and my girlfriend's mac supposedly can do video capture as is, but I've got to find software and figure it out. --------------------------------------------------------------------- O- Uncle Roger "There is pleasure pure in being mad sinasohn(a)crl.com that none but madmen know."

Yes :-) I remember the PCWs we used to have at school. They had small scanning devices that replaced the print head on the printer. The computer would make the printer scan the entire sheet of paper, line by line, and in this way it built up the image... Not the fastest of scanners, but fun to watch it go! ___ _ _ ___ _ _| (_)(\)(-) | (-)(-)(\)
