Dont know how much you yourself know about the MPC60, but you can check the spec without opening the unit as master-ceo states.
However, if you still are not sure how to check, opening the unit will also give you a visual indication of what options are fitted (SCSI, memory expansion, Roger Linn 3.1 OS upgrade) as you will literally be able to see them. There are only a few screws to remove, so it wont take long, besides taking a look at the inside will tell you a lot about the condition of the machine and what type of environment it has been in.
1. The SCSI board is centrally located and will be internally connected to the SCSI port at the back of the machine. It will be clearly labelled
SCSI INTERFACE FOR AKAI MPC60 - MARION SYSTEMS CORPORATION.

2. The memory expansion board (if fitted) will be connected to the white expansion socket on the left hand front PCB. If you can see an empty white socket, you don't have the memory expansion board. It looks like this, and may be be MUTEC/ MU-TECH branded.

3. The OS eproms are located on the PCB located in the centre base of the machine, if the SCSI board is installed it will be partly obscured. The Roger Linn 3.10 eproms are clearly labelled, and there should be four of them numbered 1 to 4.

A fully upgraded MPC60 will look like this when you open her up (this one has an internal card reader in place of the floppy).
