==Audio Program==<br />
* location 1 & 2. <br />
* Eprom size is always 128kb/1mbit. <br />
* Function of pin 2 can be either A16 or GND.<br />
* Function of pin 26 can be either A16 or GND.<br />
<br />
To use a 27c1001/27c010, A16 goes to pin 2 and GND 26 - this translates to a COOC (closed/open)configuration for JP1,2,3,4 and JP5,6,8,9.<br />
<br />
==Main Program==<br />
* location 3-10. <br />
* Eprom size is always 512kb/4mbit.<br />
<br />
==Q-Sound samples==<br />
* location 11(JP10,JP11) and 12(JP12,JP13) <br />
* Eprom size can be 2mb/16mbit or 4mb/32mbit. <br />
* Function of pin 32 can be be either A20 or VCC.<br />
<br />
To use 27c160, pin 32 needs to be VCC - this means closed/open.<br />
<br />
To use 27c322, pin 32 is A20 - this means open/cosed<br />
<br />
==Graphics==<br />
* Location 13-20.<br />
* Eprom size can be 512kb/4mbit, 1mb/8mbit, 2mb/16mbit or 4mb/32mbit.<br />
* Function of pin 32 can be be either A20 or VCC.<br />
