I don't normally read this net, but I thought there might be someone on this net might be able to help me. A friend has a Commodore 64 and I have a PC and we would like to transmit data & text files between the two. Well, mainly from the C64 to the PC. We have been able to get them to talk to each other through modems, but the files are garbled. It appears that we need to convert the C64 ASCII files to "true ASCII" before transmission. I believe that Commodore's ASCII is slightly different. Is this correct? Is there anyone that can help with this situation? Any assistance would be greatly appreciated. -- R.L.

In Commodore ASCII the letters "abcdef...xyz" have the ASCII values 65, 66, 67, ..., 90, and the letters "ABD...XYZ" have the values 193, 194, ..., 218 (ie. the values for the lowercase letters plus 128). In "normal" ASCII the uppercase letters "ABC...XYZ" have the codes 65, ..., 90, and the lowercase letters "abc...xyz" have the codes 97, ..., 122. All you need to do is write a routine that will convert the Commodore ASCII to the normal ASCII, keeping in mind there may be other characters in Commodore ASCII that don't have the normal ASCII codes. fred UUCP : {allegra|clyde|linus|decvax|utzoo|ihnp4}!watmath!grwalter CSNET : grwalter%watmath@waterloo.csnet ARPA : grwalter%watmath%waterloo.csnet@csnet-relay.arpa

I have had to port BASIC source code from a C64 to an Apple, (in fact I'm working on porting "Masterdisk" right now...) The only way I was ever able to get it to work was with a terminal program that had built in routines to convert from non-standard CBM ASCII to standard ASCII I could read with computers from the rest of the world. I also had no end of problems with the 1600 VICMODEM, apparently it refuses to work properly with any phones but the old rotary dial desk style units... The author of the C64 version of the Masterdisk program also had his VICMODEM 1600 die an infant death. A borrowed 1600 was only marginally usable. Next time we will borrow a Anchor Automations 6470 1200bps unit when we need to port code... Lee Heins {umn-cs, okstate, csu-cs}!isucs1!heins Disclaimer: My opinions are mine alone...

You were having trouble with the 1600 VICMODEM??? and now recommend an Anchor 6470??? Guess who made the VICMODEMs for Commodore? You guessed it: Anchor Automation! Also....good luck trying to get a 6470 to work with your 128. It doesn't. They came out with a "fixed" version called the 6480, but it is still not Hayes compatible, and hence will never work with any terminal program except the one that is supplied with their modem. If you are looking for a hayes compatible modem for you 64/128 that works with ANY terminal program, you need a Commodore 1670 which IS NOT made by Anchor.
