ok here's what i've learned with a few searches :
I'm not a specialist so don't take every word i say as true i'm just investigating
1. the back of a SCSI card reader looks like this :
so you don't need an adapter to replace your internal zip/floppy with this reader. maybe one for the power port but i think i already made the mod when i switched my floppy for a ZIP (which is very simple).
2. the SCSI to USB adapter needs to be plug to the back SCSI connector of your MPC. then if you connect the USB to your computer you should see the flash reader displayed as a drive.
i don't really get it as i don't know how the data goes from the card reader to the external scsi port.... but i'm ready to believe MPC3000.
Note : I already have a 9gb SCSI hard drive connected to the back SCSI port of my MPC so i won't use this method.
3. i still couldn't find an used microtech unit on ebay but i've found this message (from Oct 2002) on the akai list :
http://www.midicase.com/akai/archive/2002/oct_dec/msg00044.html
where you can read :
If anyone is looking for a SCSI CF card reader, there is usually at least
one available at the popular auction site. I bought the PCD-47's from IMS
there, who usually always has one listed.
http://stores.ebay.com/imsstore
seems like this store isn't actually selling any SCSI microtech unit. i couldn't find anything on ebay and i've tried quite a lot of search possibilities.
4. In the same message from Mike Goins (aka MPC3000 am i wrong?) you can also read this :
I've had some frustrations with the PCD-47 SCSI PC Card reader for the past couple of months. [...] Turns out that the PCD-47 had a read-only firmware installed. Richard promptly emailed me a new firmware. After installing, it now works great with all my Akai gear. [...] I will be glad to supply the updated firmware if you get one of his.
so there may be an issue with the PCD-47 but hopefully it seems MPC3000 is ready to share the updated firmware.
it's cool but do the other Microtech PCD models do also need a firmware upgrade is it the only one ?
And are the older Microtech models slower or just the same with different options ?
I'm in france so i don't want to bid on an unit that wouldn't work completely.
5. i couldn't find how MPC3000 did his mod for installing the USBXchange
inside his MPC and leave the SCSI back port available.
The big questions is : where did you connect the USBXchange SCSI side ??
Seeing this pic of your installation of an internal SCSI HD :
I guess you used a single special ribbon cable which connects MPC to SCSI Flash Reader to USBXchange (may not be the right order) ? Problem : the USBXchange port and the SCSI reader port do not have the same shape!
Also did you find enough space for the USBXchange thing ? I guess you placed it at the place of the removed angle bracket for the 8meg flash board.
----
I'm sorry to annoy you MPC3000 but it seems you're the only one to have done this mod (if you've done it!) and it's quite complicated. I could only find fragment of informations with all my searches.
Be sure that if it's working and if i manage to get my hand on a SCSI reader + a USBXchange thing i would then post a step by step guide with photos to share with everyone on this forum that would end all of this.
And hey, i've bought your MPC2000XL MPC Editor software :p
thanks
