PROTOTYPE APPLE II LANGUAGE CARD
NOTICE THE HAND WIRE WRAPPING - NEAT APPLE LOGO TOSHIBA IC
IC DATE CODES 1979/1980
-
THE APPLE II LANGUAGE CARD WAS RELEASED IN 1979 - THE 1980 ICs (post release) AND ONBOARD ROM MAKES THIS AN UNUSUAL AND TRICKY PROTOTYPE TO IDENTIFY

BURRELL SMITH PROTOTYPE BOARD?
BURRELL SMITH STARTED WORKING AT APPLE IN FEBRUARY 1979 (EMPLOYEE #282)
APPLE BEGAN WRITING CODE FOR THE LISA IN PASCAL ON APPLE IIs
THE CODING REQUIRED MORE MEMORY THAN THE APPLE II HAD AVAILABLE - SO BURRELL SUGGESTED PLACING MEMORY ON THE LANGUAGE CARD
THIS WAS ACCOMPLISHED BY BANK SWITCHING THE RAM OVER THE ROM ON THE APPLE II MOTHER BOARD
BURRELL CREATED A PROTOTYPE FOR BILL ATKINSON (THE MAIN PROGRAMMER FOR THE APPLE II PASCAL AND LISA SYSTEMS)
IT WORKED PERFECTLY AND SOON BURRELL CREATED LANGUAGE CARDS FOR THE OTHER APPLE LISA PROGRAMMERS
