MaDDuck Posted January 20, 2018 Share Posted January 20, 2018 I am trying to hook up a 1581 to an SX-64. I know how to change the device number on the 1581, but how do I change the device number for the built in drive? Any help will be appreciated!

+OLD CS1 Posted January 20, 2018 Share Posted January 20, 2018 Changing the device number on the internal 1541 is similar to that of the stand-alone 1541. You have to open the case, locate the drive main board and cut of or both jumper traces which indicate device number. I have not been inside an SX-64 for a long time, but I believe the traces which need to be cut are marked. Quote Link to comment Share on other sites More sharing options...
MaDDuck Posted January 20, 2018 Author Share Posted January 20, 2018 Thanks for the help, but there is a software method that I remember from WAY back, open15,8,15,"<<SOMETHING>>: close 15 Quote Link to comment Share on other sites More sharing options...
carlsson Posted January 20, 2018 Share Posted January 20, 2018 There is an example here: https://www.c64-wiki.com/wiki/Device_number Quote Link to comment Share on other sites More sharing options...
MaDDuck Posted January 20, 2018 Author Share Posted January 20, 2018 Hmmmm.... Looks good, thanks for finding that. Seems a bit off to have to add 32 and then 64 to the device numbers... I'll try it and see. Quote Link to comment Share on other sites More sharing options...
carlsson Posted January 21, 2018 Share Posted January 21, 2018 The command writes 2 bytes to memory address $0077-0078. It seems $20 (decimal 32) is added for the LISTEN bit and $40 (decimal 64) is added for the TALK bit, per the 1541 disassembly.If you like to disable head knocking on bad sectors, you can use this: OPEN 15,8,15:PRINT#15,"M-W";CHR$(106);CHR$(0);CHR$(1);CHR$(113):CLOSE 15 Quote Link to comment Share on other sites More sharing options...
