This is a mystery EPROM found in UD11 (TMS2532 EPROM) in a CBM8032. I am pretty sure, it is a driver for the 1541 for the User Port. After SYS40690, it prints "vc-1541-dos/80". I have disassembled it with C64Studio and fixed some labels already. I noticed, that at $A390, Port A of the VIA is manipulated. There are routines to set and clear Bit 4 and Bit 5. 

I have also found a Copyright Statement at $A2F7 "(C) G MUTZ (84)H".
