Risc PC - VRAM
The amount of VRAM determines the maximum resolution and number of colours. It has its own dedicated slot on the Risc PC Mainboard.
If it is single sided then it is only 1 Mb if it is double sided then its 2 Mb.
VRAM 1Mb (0197,003)
VRAM 2Mb (0197,004)
VRAM 2Mb (0197,004) Early Version ?
VRAM 2Mb Simtec
Risc PC - Power Supply (PSU)
If your planning to run extra hard drives the larger power supply is useful. I had issue's when running 2 hard disks and a CD drive with the low power supply.
Low Power Supply (0197,110)
5V = 7.9A, 12V = 2.05A High Power Supply (0197,010)
5V = 11A, 12V = 3.6A
Risc PC - Overclocking StrongARM
Note: The StrongArms speed is written on the processor (not really sure if it is any use tho!)
Note: The StrongArm is by default locked by tracks on the back of the board forcing two switches to be on. To overclock it these tracks must be cut. Careful not to cut other tracks and tracks deeper in the board !
