Description

The module SRM-01 is an expansion of 32kB RAM with DIN RGB output. It was made and sold by Yamaha. Product name is 32K RAM/RGB Unit.

It is only for a Yamaha or derivative computer (Victor, Sakhr) with 60 pins slot. It is not compatible with the regular 50-pin MSX cartridge slot.

Its RAM is placed on pages 0 and 1 (0000h~7FFFh). As such it is only useful to upgrade a 32kB MSX to 64kB. However the systems base memory and the expansion will be in different slots which can cause compatibility problems with some software that blindly assumes all memory to be in a single slot.

NOTE!
If you are looking only for a memory expansion we recommend to buy another standard expansion. A 64kB RAM expansion, or even better a Memory Mapper cartridge that initializes its segments itself at start up is the best choice.


Official price: ¥12,800
