Replica 1 plus Users Manual Programming in BASIC: To start the replica 1 and enter BASIC, turn on the replica and press reset. Next type in: E000R [RETURN] The memory contents of E000 are displayed and BASIC begins. The prompt for BASIC is ‘ > ’. This is how you know you are in BASIC. Here is a simple ‘HELLO’ program you can type in: 10 PRINT “HELLO WORLD!” 20 END RUN When you type in RUN, the program will print out “HELLO WORLD!” onto the display, and then it will return to the prompt. You can view your program by typing in “LIST”. To get started programming in BASIC, read the BASIC manual. There are many example programs on the internet to help you get started. Krusader:
The replica 1 has 8K of EEPROM (ROM) space onboard. 4K is used for BASIC; 256 bytes are used for the Woz monitor. This leaves just under 4K available. Now, thanks to Ken Wessen, that space is now occupied with a powerful assembler called Krusader. To start Krusader, type in ‘ F000R ’ [return]. To program the assembler, refer to the Krusader manual for sample programs and commands. Changing Boot ROMs: Now that you have experienced the replica 1 like it was with the apple 1, you can use a new revised version of Applesoft BASIC that was modified to work with the replica 1. Place the jumper on the ROM select with the power switch in the off position.
Turn on the replica 1 and press RESET like usual. The Woz monitor is still there but when you enter E000R and press ENTER, the prompt is now a “]”. You are now in Applesoft lite. Some features like graphics commands have been removed to make it fit in only 8K ROM. © Briel Computers 2014 page 22
