I'll try to answer your question, but someone correct me if I'm wrong. Print Shop has no stand-alone "drivers". I ran it and looked for those files. It works with Commodore printers as the "default" but has a menu to be able to select Epson emulation. The "driver" or printer translation is embedded in the program. The graphics disk that comes with the program has two sides... side one is for use with the 1525 (MPS801) and I imagine it would also work with later Commodore printers like the 1526 (MPS802). Side two is for use with other printers... Epson, Okidata, etc. I don't believe you could use a driver made for one program with any other program, assuming they had software "driver" files. It's apples and oranges. Print Master has driver files for different printers, but none listed on my disk for the 1526. Can I assume the one for the 1525 would not work? There are two files... the other one is for the MPS801. Don't know why they have two... I thought the two printers were alike as far as drivers. Guess not. Looks like we're batting an even zero here.

When I first got the game it didn't work, so I sent it back to Origin and they sent me a new one. The next one I got didn't work becuase it was impossible to end. I would go to the designated place, and do the "rumplestilston" thing or whatever and it would never work. If you still want to possibly borrow it email me and we'll talk it.

So now it makes more sense when I tell you that CCCUG (Central Coast Commodore Users Group) monthly newsletters are not only available on the Web at: http://www.slonet.org/~rtrissel but can be requested by e-mail at: rtrissel@slonet.org Currently, the months of July 1995 through June 1996 are on the Web site. June 1995 is only available by e-mail. I'm only maintaining 12 months on the Web. Recently there have been discussions about using a C-64 or C-128 on the Internet. Here are the experiences our club members have had accessing the Internet with Commodore 8-bit computers. We started with Novaterm 9.5 on C-64s with 1200bps modems. Novaterm is shareware ($25) and is available for downloading from several sites or can be ordered from: nrossi@jarthur.claremont.edu We access a local provider ($13/month) (central coast of California) that allows 1200bps and up, and provides a Unix shell. From this shell we can run: LYNX for text browsing of the Web, PINE for reading and posting e-mail and newsgroup articles, TIN for reading and posting newsgroup articles, TRN as a poor substitute for TIN, PICO for editing files, VI and EMACS for masochists that don't use PICO, LESS, MORE, and PG pagers for reading documents to screen, X-modem, Y-modem (batch), and KERMIT for up and downloading files, TALK, YTALK, and WRITE for message display to people online, PERL and Shell Script programming support, GOPHER, TELNET, FTP, and every UNIX command on the system, and have personal Web pages. On my Web pages on this system I have a guestbook, two access counters (one provided by the system, and one of my own in Shell Script), and two access loggers (one provided by the system, and one of my own in PERL). My logger tells me the who, when, how, and whence for every access to every page on my Web site. We now have moved to using DESTERM 128 V2.00 on C-128s with 2400bps modems. It has more features and a better 80 column display. It also is shareware for $25. It can be requested from: mdesmond@ionline.net. There are sites that have it for downloading (I don't know the addresses). One member is happy using DIALOGUE with Swiftlink and a BOCA 14.4kbps modem. That is Scott Eggleston, publisher of The Underground Commodore Magazine, an excellent magazine for $12 for 6 bi-monthly publications. He can be reached at: underground@tcf.com The offline file conversion, text editing, HTML programming and file management is being done with The Write Stuff word processor. Can the Commodore C-64 and C-128 be used on the Internet? You bet!

C64's are fairly immune, since most programs require the machine to be re-booted for them to exit. The virus is "killed" before it has a chance to spread to another disk. Try formatting a blank disk. Yeah, it sounds silly, but I've seen copy protection that will seemingly screw up a disk drive, but is completely fixed by just formatting a disk. I'm assuming it has something to do with the head alignment, but I've never tried to trace down the problem so it's just a wild guess at this point. - Mark Sokos (msokos1@gl.umbc.edu) Electrical engineer, computer geek (er, programmer) in training, no-talent bum musician (have bass, will travel), and perpetual student #! rnews 2614 Path: pravda.aa.msen.com!spool.mu.edu!howland.reston.ans.net!newsfeed. internetmci.com!skylink!shell.skylink.net!mrx From: mrx@skylink.net (Mr. X) Newsgroups: comp.sys.cbm Subject: Re: More text adventure questions Date: 30 Jun 1996 16:59:08 GMT Organization: Skylink Networks (http://www.skylink.net/) Lines: 36 Message-ID: <4r6bos$gcm@news.skylink.net> References: <4r2nn4$q5u@ruby.ucc.nau.edu> <4r2u9g$14n@seagoon.newcastle.edu.au> NNTP-Posting-Host: shell.skylink.net X-Newsreader: TIN [version 1.2 PL2] pap@dana.ucc.nau.edu (Paul Allen Panks) wrote: : >In the game I am working on, I need to possibly save data to disk either : >as Sequential files or Random files. : > : >I've tried using the input#x command in a for-next loop to extract an : >individual room description, but found to my dismay that the command : >truncated off any text after a comma (,) in a string.

That should be good for anything, but only 1 char at a time, you have to do your own seperators, etc.... Also, even though REL files would sound perfect for this, be warned that they are slow and buggy! :( Also, don't forget to use the 4K block of RAM at $C000 (49152) to buffer your data to reduce loads, something like an LRU (least recently used) algo and/or space map. For example, if you could go 4 directions from your rooms, you'd want to have the current room and the room in each direction in RAM (actually more, but you'd need to make more room by reduceing BASIC space or something) in your space map. But in an LRU algorithm, you'd have a list ofthe most recent rooms you've been in (however many you have space for) and each time you need to load a new one you'd check to see if you already have it, if you do, great, if not, throw out of RAM the room that you haven't visited in the longest time. This is better than a space map because if you run up and down a 'hall' of rooms or back and forth between a few rooms, you won't have to load every single time. Of course, you might wanna store all the numbers and other data in RAM all the time and just do the text this way. You could even use variable lengths for room text in RAM. Keep track of the length of each room data and store them at 49152+0, 49152+length1, 49152+length2, etc until you run out of 4K or you could just store 4 rooms at 1K each or 8 rooms at 512 bytes each, etc.... ________________________________________________________________________ (c) 1996 mrx@skylink.net All rights reserved. www.skylink.net/~mrx #! rnews 1232 Path: pravda.aa.msen.com!news1.best.com!nntp.primenet.com!news.mathworks.com! newsfeed.internetmci.com!news-feed.iguide.com!news.delphi.com!usenet From: Lonnie McClure Newsgroups: comp.sys.cbm Subject: Re: Need help with C128 composite cable...

Well, I never pretend to be a hardware guru, but sometimes I take the work of people who are supposed to be. In this case, when I got my Amstrad PPC640 (dual 720K PC compatible) and the University had 1.44 drives. Now, *mind you*, I was never told the tracks were half width, just that the newer drives wrote them skinnier than the old drives, so that the 1.44 <-> 720K transfer was problematic. It could have been a combination of confusion with the 360K <-> 1.2M problem and the occasional problems with some HD disks not being easiy overwritten by DD drives when they've been written by HD drives. Like I said, it might have been the wrong hardware problem. I never had to find out because the solution worked! 8-)# Virtually, Bruce R.

I also wonder about how tightly regulated some 1581 power supplies are when faced with low voltage current. A drive that was 'on the borderline' in one location might plug into another and either 'hmm, why doesn't it work'? or 'hey, that's a lot better, wonder what fixed it?'.

I will endevour to make no more hardware pronouncements until I have built some hardware of my own to pronounce about 8-)# -- Virtually, Bruce R. McFarling, Newcastle, NSW ecbm@cc.newcastle.edu.au
