- Whats New
- 16MB support
- Abolished the compatibility for Ver1.01 or before.
- Command 41h was abolished and command 42h was changed.
- SmartMedia Utility was chenged.
- Don't use SmartMedia when battery level is low. It may cause terrible problem.
- BASIC command DSKF or HMF doesn't return the correct free disk space.
Revolution(by Aesop M601) returns correct value.

- If you use 4MB media and DS Ver1.14, you cannot create any file in the sub directory which made by DS.
Download the fixed version and replace with original DS.
Not necessary formatting or remaking directories.

SmartMedia is very compact (L45xW37xH0.76mm) and PC-E500 has enough space to place SmartMedia. But, If you have already installed other devices on PC-E500, there might be not enough space.
I've already installed 2 stacked 128KB-RAMs, clock IC(RP5C62), 3 seramic resonators(2.3MHz,4.8MHz,8.0MHz) and 4 logic ICs.
This is the SmartMedia adapter still in the experimental stage.
