Internal accelarator for 8bit ATARI XE series.
- internal CPU turbo card for Atari XE,
- WDC 65C816 microprocessor operating at 20 MHz!!!
- managed by Xilinx Spartan6 FPGA and XC95XL CPLD devices,
- 1024kb of zero waitstate SRAM,
- up to 30.5MB of storage ram - SDRAM clocked at 160 MHz!!!
- 512kB of Flash memory (256kB is reserved for FPGa cores, 256kB for OS and New Device handler)
- 256b of EEPROM,
- high speed bus connector for external I/O interfaces, DMA support,
- working modes, fully software controlled
- low power consumption due to DC/DC converters, no extra power supply required
- simple installation: put Rapidus board in place of old 6502C and just solder 3 wires, or use an Adaptus board - this depends on the model of your computer. In this case you don’t have to solder any wires.
- compatible with Ultimate 1MB
- on some ataris below patch has to be applied
- O2 signal pull down - in case, when Your rapidus have problems with core loading (progress bar stops), please, make another patch: solder 3kOhm resistor between 74LS08 pin 1 (o2) and pin 7 (Gnd)
