This listing is for an RAD Expansion Unit with 3D printed case designed by me.
 Please write a note in your order of what colour you want otherwise random will be send.

This cartridge can incorporate either a Pi Zero-2 or a Pi 3A+ that's not included in the listing.

 The RAD Expansion Unit is a cartridge/expansion for the C64 and C128 using a Raspberry Pi 3A+ or Zero 2 to implement the actual functionality. 
 Currently it emulates a RAM Expansion Unit up to 16mb (compatible to CBM 1700/1750/1764 REU, CLD Super 1750 Clone, CMD 1750/1750XL) and a GeoRAM/NeoRAM memory expansion up to 4mb. 
 It also features a menu to browse, manage and launch REU- and GeoRAM-images, NUVIEs, and PRGs. 
 The RAD is designed to not only emulate existing extensions, other things that have already been tested (but not yet included here) are, for example, MOS 6510/8500 emulation (incl. turbo mode) or using the RAD as a (co-)processor (in fact the menu runs on the ARM CPU only).

RAD has been tested with various PAL-machines (C64s, C128, C128D) and NTSC-C64s. More tests with SX64, Ultimate64 and C64 Reloaded boards, RAMLink etc. remain to be carried out.

RAD can be used as a REU cycle exact emulator up to 16MB to be able to play all games/demos/utils than needs a REU ram upgrade, like Sonic the Hedgehog, NTSC Sams Journey etc.
 
Also it can act as a CPU upgrade on the C64/128 utilising the ARM cpu of the Raspberry Pi, there is a port of DOOM for that mode that can be run on the C64/128 utilising 1 or 2 SID chips running amazingly fast.

The case is using the short RAD pcb and its designed to be used with either Pi Zero-2 or Pi 3A+ having all their ports available via holes on the back of the cartridge.
