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, PRGs and Vice Snapshots (VSF). The RAD also supports an external disk drive and printer emulator, the IECBuddy , which is the result of a great cooperation with David Hansel. The IECBuddy can be used to synchronize files with the RAD and is integrated into its menu. 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), using the RAD as a (co-)processor (in fact the menu runs on the ARM CPU only). With the RAD you can also play Doom on your C64/C128. RAD's functionality is entirely defined by software. The connecting circuitry is quite simple and does not include any programmable ICs and is thus easy to build. It's a sibling of my other projects: Sidekick64, SIDKick pico and SIDKick. The RAD has been tested with various PAL-machines (C64s, C128, C128D) and NTSC-C64s/C128s, as well as with the Ultimate64 (the inner workings of the Commodore 64 Ultimate). More in-depth tests with SX64 or C64 Reloaded boards remain to be carried out (not by me, I ","default_branch":null,"files":null,"tree":[],"storefront":"/r/frntc","claimed":false,"request_supported":{"post":"https://gitbuyer.com/r/frntc/RAD/request-supported","requests":0},"note":"indexed from public GitHub; nothing is for sale on this page.
