🍎 Apple-I Emulator
Authentic Clock Speed
This emulator runs at the authentic Apple-I CPU speed derived from the NTSC master crystal:
14,318,180 Hz ÷ 14 = 1,022,727 Hz ≈ 1.022727 MHz
Woz Monitor Commands
After booting, you'll see a backslash (\) prompt.

XXXX.YYYY — Dump memory range
XXXX: DD DD DD — Store bytes at address
XXXXR — Run program at address (e.g. E000R for BASIC)
Tips:
• All input is UPPERCASE. The Apple-I had no lowercase.
• Press CR (Enter) to execute commands.
• You can paste text (Ctrl+V) to enter programs quickly.
• If you loaded BASIC ROM, type E000R to start BASIC.

• The blinking @ cursor replicates the real Apple-I!
