LM80C 64K firmware R1.20

Revised ERASE command: now, it recovers the original file name, by simply setting/unsetting the MSBit of the file name when deleting/undeleting the file.

LM80C 64K firmware R1.19

• New function EXIST() to check if a file is already present into the directory;
• introduction of GET(0) to roll back the internal pointer of a sequential file opened for reading;
• fixed a bug into the new keyboard shortcut CTRL+ALT (C=);
