1541 drive connect with PC

X1541.EXE by GHIELMET@eldi.epfl.ch (Leopoldo Ghielmetti)

The X1541 program requires an adapter cable to connect your PC parallel
printer port (LPT1/LPT2/LPT3) and a commodore disk drive (1541/1581).
*(The Female port pinouts are shown below. The normal cable is Male-Male.)

type "x1541"   for the interface scheme (see above)
type "x1541 ?" for the options list
     options are : "/b" force monochrome mode
                   "/c" force color mode
                   "/LPTn" force I/O from LPT port n (n in range 1..3)

     Activate Menu or to dismiss menu and go to file list
          Also used to dismiss status boxes (after COPY)
   Highlight memu or Select menu item
    Highlight menu

 or  Go back; Highlight previous menu

1541-COMMAND Note:     command letter (e.g. N0:Test Format,tt)
                   Must be capital letter --^


**** Brief command sequence for file copy ********

1. OPEN 1541    to select and highlight Drive# sub-menu
                to select drive number (8-11)
2. OPEN IBM
3.  to source filelist
4.  selects file(s)
5.  for menu
6. COPY
7.  to dismiss status box after copy is complete

DE NADA

Well I forgot to mention it, to make a file with another extension (seq,
usr, rel (not yet supported)) you should give the correct extension to the
IBM file Eg. *.seq will be transferred as sequential file (seq)

In normal condition 1581 and 1571 have the same mechanism as 1541 but for
lack of documentation I did not implement the fast serial mode feature.

ciao, Leopoldo
