Ice Multiboot Release 2

For the eepizza LX9 board + new family of active level shifters

Contains multiple FPGA designs in a single .mcs file:

• a multiboot loader
• ICE-6502 (Mode jumper = 0) - uses the cycle accurate T65 core
• ICE-65C02 (Mode jumper = 1) - uses the AlanD 65C02 core
• ICE-Z80 - uses the T80 core
• ICE-6808E - uses the SYS09 core

In this release there are three changes:

1. Firmware revision is now 0.84

2. ICE-6809E has been added, this is currently untested

3. ICE-Z80 has undergone a major re-write, and has been tested successfully on:

• ZX81
• ZX Spectrum 48K (Issue 4S)
• ZX Spectrum +2B
• Acorn External Z80 Co Processor
• Amstrad CPC 464
• Micro Professor MPF-1

Notes:

• On the 6502/65C02 board you need to fit R10 (ID0) only.
• On the Z80 board you need to fit R11 (ID1) only.
• On the 6809E board you need to fit R10 (ID0) and R11 (ID1).

Ice Multiboot Release 1

For the eepizza LX9 board + new family of active level shifters

Contains multiple FPGA designs in a single .mcs file:

• a multiboot loader
• ICE-6502 (Mode jumper = 0) - uses the cycle accurate T65 core
• ICE-65C02 (Mode jumper = 1) - uses the AlanD 65C02 core
• ICE-Z80 - uses the T80 core

On the 6502/65C02 board you need to fit R10 (ID0) only. The "Mode" jumper then selects between 6502 (off) and 65C02 (on).

On the Z80 board you need to fit R11 (ID1) only.
