PowerBase RAM Specs

I am interested in upgrading the RAM on my PowerBase. Could you give me the specifications for the RAM and what upgrade options are available to me.
The PowerBase and all Alchemy based machines require EDO DIMMs.  Fast paged mode DIMMs, which are commonly used on previous machines, will not work. Below are the slot and RAM specifications for PowerBase.  

DIMM
Type                  EDO
Speed                 60ns
Parity Setting        Non-Parity
Refresh Rate          2k  DOES NOT SUPPORT 4k
Buffered?             Yes
Voltage               5V

DIMM Slots
Back  Slot 1 (Bank 0)      Must use a single banked DIMM, 32MB or less
     Slot 2 (Bank 3,4)    Can use either double or single banked DIMMs up to 64MB
Front Slot 3 (Bank 1,2)    Can use either double or single banked DIMMs up to 64MB

*Power Computing uses:
    Single banked: 8MB, 16MB and 32MB DIMMs  
    Double banked: 64MB DIMMs

*Maximum amount of RAM = 160MB.

**SPECIAL NOTE FOR 16MB DIMMS
Customers must specify "2 X 8 Density, 2K refresh" rate for 16 MB DIMMS. DIMMS with 4K refresh rate explicitly will not work.  Power Computing knows that both Tech Works and the Chip Merchant have these DIMMS in stock.
