Made a new build of MIKBUG. It runs serial only but gives 9KB of SRAM internal to the SRAM.

M6800_MIKBUG _Serial- Tested/Works

• MC6800 CPU
• Running MIKBUG from back in the day (SmithBug ACIA version)
• 12.5 MHz
• 9K (internal) RAM version
  • 8.5K User SRAM
  • 0.5K Scratchpad SRAM
• MC6850 ACIA UART
  • No VDU

Memory Map

• $0000-$21FF - 8.5KB SRAM (internal RAM in the EPCE15)
  • User program SRAM
• $7E00-$7FFF - 512B SRAM (internal RAM in the EPCE15)
  • 0x7E00-0x7EFF available for user
  • 0x7F00-0x7FFF are used as scratchpad RAM by MIKBUG
• $8018-$8019 - ACIA
• $C000-$CFFF - MIKBUG ROM (repeats 4 times from 0xC000-0xFFFF)
