The RAD Expansion Unit is a cartridge/expansion for the C64 and C128 using a Raspberry Pi 3A+, 3B+ 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'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.
Sells OEM RAM for computers.
A utility for Linux that attaches to a running process and searches the memory field for strings supplied by the user. Once found, you can then change the string to a different value. This works much like the pokefinder utilities on the 8-bit computers.
Online app that converts file sizes into other units (i.e., megabytes into bytes, kilobytes into gigabytes).
A poster of every extant processor, socket, module, and jack in use by computers today. Comprehensive and impressive. You can even buy a print of it if you want.
