The Buffee supports everything your Amiga can do right now. It supports all of the talks with the Amiga hardware. There will be no compatibility issues when using this accelerator. 32-bit memory is also supported. Check all of the details below.
Important info about the Buffee accelerator is when the accelerator is connected to the 68000 CPU socket, then Buffee will operate in “ultra compatible mode” and will require that the user or retailer preconfigure Buffee beforehand. Settings can however be configured later with many options by using CLI. Once saved, it will stay like that until you change again.
Buffee settings that you will be able to change
- Enable CPU local RAM in 32-bit memory (disabled by default)
- Set the location and amount of this RAM
- Enable data and/or instruction caches for any memory block (by default only the instruction cache is enabled in 24-bit memory, all caches are enabled for 32-bit memory)
- Enable PJIT instruction cache for any memory block (by default, PJIT ICache is enabled only on 32-bit memory)
- Set the CPU base clock PLLs (presets for 275 to 1000 MHz)
- Set the CPU clock divider (from 1 to 1/256th of the base clock)
- Select between 68000 or 68030 instruction set (68000 default)
- Select between No FPU, 68882, 68040, or fast 68040 FPU modes (No FPU is default)
- Enable 68K MMU emulation
- Preload and remap up to a 2MB ROM image (with or without 68K MMU enabled)
When changing the settings in CLI. These can be saved into the EEPROM memory which will be retained while powered off for decades. Buffee is meant to be an accelerator not just for Amiga, however, it will be a perfect match for Amiga 2000 owners. Buffee and ZZ9000? Now that must be a beast.
This is similar to how I am changing Warp1260 settings through CLI where I can tell the Warp1260 card to use different clock speeds and also tell Warp1260 to either use its IDE controller or the internal one that Amiga 1200 got. It is very convenient.
There are no Amiga hardware limitations
- Autoconfig and Zorro-II
- In-socket expansions
- All 2MB of chip RAM
- Any fast RAM you might have
- Any “ranger” RAM you might have
- The original OCS all the way to ECS
- Floppy drives
- Custom ROMs
- CDTV expansion ROMs
Buffee will be a very interesting product once it is out. The Amiga community is fortunate to have so many options. Chose wisely. Come to Classic Amiga Software on Facebook. Ask any Amiga related questions.
