It's amazing what's possible with the ACSI-interface. Even if it's just a SCSI derivate
Fully agree, the way SuperCharger was smart and technically elegant.
You can connect up to 6 x SuperCharger to only one ATARI ST. Each SuperCharger is independent and can execute its own MS DOS instance and program you need to run on. The only limitation is the shared storage but with modern drive using SD card latency and read/write speed is not really an issue.
Beta Systems does also provide API to be able to use the SuperCharger as a compute node for the ATARI ST.
SuperCharger can also be used as a ram drive providing additional 512Kb up to 1Mb reset proof volatile storage.
