SupraDrive 500 expansion Question

[luvtofish]

I just picked up a Supra sidecar expansion, 2MB MEM, with a 20MB hard drive for my Amiga 500. The hard drive and enclosure connects to the back of the sidecar via SCSI cable.  

I noticed the sidecar itself has what appears to be an expansion port on the left side (accessed by removing a few screws) that would allow connecting an additional sidecar or other device. Does anyone know what this is for and what it does for sure?

Also, if I wanted to update the hard drive, does any 50 pin SCSI work?

Thanks

It appears I have the AMAB5 CHIP. Do you know how big a drive is supported by this chip? I know there is an AMAB6 chip out there, just don't know where I can find one.

I would love to get something larger than 20MB but I'm not sure what drive to get. Do these take SCSI I 50 pin?

Thanks

Thanks! I'll contact him via ebay and see if he has any for sale!!

The drive bay has a built in power supply. I merely had to plug in the standard PC power cable to power it up.

Mine is the SupraDrive 500, not the XP model. I'm not sure what the difference is.
