Not much known.
Reportedly, the RAM is accessed in 128-byte sectors.
The RAM is accessed using I/O ports. It can not be banked in like common RAM expansions do. So it's a real RAM disc, not an RAM expansion. There was support for FutureOS for a while (up to system 0.6). That support was abandoned later due to the very high price of the RAM disc (more than 1000 DM) corresponding to a very small number of units sold.
I/O Ports
- F9FC - #F9FE Otten & Fecht 1 MB RAM-Disc (R/W)
- FBF0 - #FBFF Otten & Fecht 1 MB RAM-Disc (R/W)
(Data taken from the FutureOS manual).
