Just in case someone stumbles across a
SCM PCD-60B multi card reader: this device has been manufactured in different flavours, for read only purpose and for read and write access. I bought one that was pulled from a self service photo printer. It came with firmware version 01.13, which does not permit write operations. I checked the operation with an old PC running Win NT 2000. With this system any LUNs are independently accessible, with the following results:
LUN 0 PC Card
LUN 1 CF
LUN 2 SmartMedia
LUN 3 SD Card
LUN 4 Memory Stick
LUN 5 xD Media Picture Card
A firmware update tool is available to flash the devivce to firmware version 01.28. This firmware flash tool is a Windows application, what is another reason for me to keep that old Pentium III server with SCSI host adapter. It is most useful to run some tools like this firmware flasher. After a succesful update to firmware 01.28 the multi card reader is completely operational under Win NT 2000, accessing each LUN separately.
On a beige PowerMacintosh G3 DT running Mac OS 9 the results are inconsistent, yet. The G3 boots from a HFS+ formatted CF-Card in a PCMCIA-CF-adapter using LUN 0 of the card reader. SCSI Probe then detects and mounts media in other slots, also. Drive Setup does not support the card reader. HDT 2 seems not to like the device at all. So I would not call this a full success at the moment.
However, booting from the internal IDE drive (in this case an 8 GB flash disk on module, which contains a differently configured Mac OS 9) renders the card reader unusable. The system reports the media in the PC-Card slot as faulty and SCSI Probe tells simply "LUNs not supported". In consequence I suspect the operability of the card reader is not connected to the hardware or to the installed OS in general but to some particular software configuration I have not the time to figure out right now.
If someone knows which configuration is necessary and what to avoid in the System folder, please let us know.
P.S.: the SCM PCD-60B has a jumper to enable or disable termination power
