    hmm what happens when you run the program without any disk in the drives?

    0 "" 0 0 is just zeroes coming from the bus. Make sure your cable is good, that the connectors are clean and making a good connection.

    Sorry for being inactive so long. The cable is making a good connection (I checked with my multimeter). I cleaned the connectors and the drive now reacts when i run the program. It says "21 read error 39" on drive 0 and 1, with and without a disk

    Is the disk formatted with 8050/8250 format? In theory, no disk should give a 74 error and an unformatted (or differently formatted) disk should give a 21 error, but it might be an older DOS version, I'm not sure what would say a DOS 2.5 8050.
    Do you have a spare disk that you can try formatting?

    I got 2D double sided double density 48 t.p.i soft sectored disks at hand, can i format them with the 8050 format? And if yes, how?

    yes they would be fine for that drive.
    You can format them with:

    open15,8,15,"n0:disk name,id"
    close15

    with a disk inserted in drive 0, or change n0 to n1 for a disk inserted in drive 1; id can be any two characters.

    It will work in both basic 2 and basic 4 (with basic 4 you have an additional way: header "disk name", d0, ixx
    Again, d0 if the disk is on drive 0, d1 if on drive 1. xx can be any two characters, it's the disk ID).

    I typed this in and the drive did something for about 30 seconds, then the front led turned red. How do i test the disk?

    If the led turned red, it couldn't format the disk. Did you try on both drives?
    Try a few different disks also, after all these years, they might not be "as good as new" anymore.
    However, let's try this simple program to go somewhat faster in trying different disks/drives:

    10 input "drive number (0/1)";d$
    20 open1,8,15
    30 print#1,"n";d$;"test,7x"
    40 input#1,e,e$,t,s
    50 print "format results:"
    60 print e;e$;t;s
    70 close1

    insert a disk on one drive, then run the program and answer the question with the drive number you put the disk into.
    Report what errors you get with a few different disks on both drives.

    It says "34 syntax error 0 0" everytime

    ops! That's what happens when I don't test programs first :/

    change line 30 to:

    30 print#1,"n";d$;":test,7x"

    basicly there was a missing : before the word 'test' which is just the disk name being assigned to the disk.
    Now it should work
