I am looking for a program to make a PC with harddisk acting as a file-server for a C64. The C64 must see the PC as a normal disk, accessable over the serial Commodore bus, just as it can acces a 1541 (ugh) diskdrive. A nice option would be the use of a printer connected to the PC by the C64. If such a program exists, together with a document which describes the cable between PC (AT) and C64, please let me know. Send it to me by email, or send me the address of a MAIL based server from which i can order the program (No FTP for me :-(). If the program does not exist, please send me documentation, maybe I will write it myself. --------------------------------------------------------------------- Phons Bloemen phons@cs.kun.nl Sophiaweg 244 6523 NJ Nijmegen NL +31 80 236769

I have certainly never heard of such a thing and have had C64's and C128's for many years and am a member of ICPUG the UK user group. I am pretty sure that some hardware will be needed as well as software because the C-64 serial bus is a chopped down IEEE-488 (? number) bus which is not compatible (or even similar) to anything the IBM-PC has. The one thing it has going for it is that it runs 5volt TTL levels which from the voltage level point of view would work with the IBM-PC parallel port. The three most likely approaches are:- 1 - Produce a 'pseudo-IEEE' interface for the IBM and connect to the C-64 serial bus. This is probably easy software but expensive/difficult hardware. 2 - Special software in the C-64 to redirect disk I/O to the user port and connect to the IBM-PC parallel port. This would entail little hardware but a lot of software at both ends. 3 - Use an RS232 adapter on the C-64 and a small amount of software modification to redirect disk I/O to the RS232. Connect to the IBM-PC RS-232 port and (hopefully) use one of the cheap IBM-PC programs which allow networking via the serial port. Chris Green (chris@kbss.bt.co.uk or cgreen@ibmpcug.co.uk)

The C64 serial buss is indeed a modified form if the IEEE standard orginally installed on the PET line. Thereisn't any practicle way to share data with an IBM that way. The only way I know of is to connect the C64 User Port via an interface to the RS-232C of the IBM.
Omnitronix, Inc. makes the Deluxe RS-232 Interface. I recommend it as the best on the market.
