For anyone who can be interested in details used to install the reader in mpc 2000 xl (one more satisfied user

) :
Before switching from the floppy drive - I made upgrade of the OS to the 1.14 version (as Lampdog sad

)
The jumper setting - I left it as it was (default) when the reader arrived,so it is closer to the power cable.
I tried using both: the card reader and my external 100 MB Iomega zip drive,to copy the stuff (programs,sequences and sounds) to the memory card.The termination of the zip drive was ON and the SCSI number was 5 (don't know if this has any meaning,just giving all the details

).It works perfect ! No problem in copying everything.
I bought this reader of course

Memory card used - Kingston 512 MB Flash Card
that's all I think
To anyone who is thinking about installing card reader - go for it !!
