A 50-year old book (or even older) can still be a very entertaining or informative read, and although some music goes out of style, it can also become popular, and if you liked it then, you probably like it now. Books don't require external equipment to use or enjoy. Music typically does (an instrument to play it, or something to listen to it on), but when was the last time a piece of music fell out of publication simply because the instrument or played it on, or more likely, the machine you listened to it on, is no longer manufactured? The vast majority of software is very machine specific. When demand for the machine it works on dies, so does the demand for the software that runs on it. Music and books "die" only due to unpopularity. When 8-track tape players lost out to cassettes, the music that was still popular went to cassette. The same with LP's vs. CD's. The music did not have to be "reprogrammed" or "ported" as a program is...simply re-recorded. If every computer could run every piece of software ever written (requiring only 're-recording' when the popular formats changed from punched paper tape to cassettes to 8" and 5.25" floppies to 3.5" floppies), then it would make sense to treat software the same. Personally, I think the world would be much better off if the copyrights on software where intially 5-10 years, but renewable for approximately the same length of time as current copyright laws allow. Personally, however, I can't think of any type of software that should require 50-75 years of protection. I cannot even imagine a later series of a mainframe running the same code, even if portable, as its predecessor used half a century ago. Still, it would not hurt to allow such renewals. Even a 10 year period of protection, followed by a single renewal for the remainder of the usual term would be a benefit. How many 8-bit software makers have ceased to exist during that time, with whoever inheirited or acquired the rights as part of the company assets either not knowing they had the rights or not caring, within such a period of time? The problem is, there changes a few years ago to the US copyright laws were primarily to bring it "in sync" with that of many other countries, meaning that one would have to lobby not only for changing US copyright laws, but that of many nations, in order for the US to consider such a change. Also, I expect many software companies would fight such a change, despite the fact it would have virtually no impact on their bottom line.

No, I talked to Tom yesterday (2/26/94) and he said he has all his hardware problems fixed except a new power supply. I talked with him about a week before and told him I respected his decision to quit the board. He just continued the conversation like it was going to be done. That's why I posted the original notice that CTH was going down. The termination of a 10 year BBS is a complex decision and I don't know what Tom is going to do. Right now, it seems the board is going to stay up. Russ Gilbert cb541@cleveland.freenet.edu Empfaenger : /comp/sys/atari/8bit Absender : (Michael Current) Betreff : Re: ??

What is the purpose of this knob? Finally, how can I tell by inspection if this machine has the CTIA or GTIA chip? So far I don't see any chip labels that indicate either (but there are a few chips under the plastic thing surrounding the cartridge ports and card slots... I havn't removed that part yet.)

The Apple IIGS (my computer) used a similar method you are talking about: it has a 65C816 with the custom chips required for Apple II compatibility plus the required hardware for 24 bit memory addressing etc. In my opinion, one of the main reasons it didn't really get off the ground is cause Apple charged too much for it (so, what else is new huh?). But because of it's relatively complex design (GLU logic, Apple //e on a chip, fast and slow side of motherboard and a few others), It actually cost more to build (at the time) than a Macintosh. While the 65802 doesn't have the 24 bit addressing, it is pin compatible with the 6502 and would only take modifications to the assembler in order to support the new opcodes... Good luck on this project everyone! May the Atari 8 bit live long and prosper!!!!! Katishna J.

Allows you to chain ALL peripherals, to one file server, and attach up to 8 more slaves all sharing those same peripherals.
