Please verify that any SIMMs supplied by anyone other than Kingston meet the IBM specification before using them. The table below shows all of the SIMM types that can be installed in MCMaster. Note the MCMaster DOES NOT support 1MB or 2MB SIMM modules.

Size	Configuration	Kingston Part No.
4 MB	1024K x 32, 70ns	KTM1x32L-70T
8 MB	2048K x 32, 70ns	KTM2x32L-70T
16 MB	4096K x 32, 70ns	KTM4x32L-70T
32 MB	8192K x 32, 70ns	KTM8x32L-70T

MCMaster can also function with no onboard memory installed, using only memory that is already installed in the system. Be aware, however, that running MCMaster with only off-board memory extracts a performance penalty, especially in a 16-bit PS/2 system like the model 50 or 60.

This table shows all possible combinations of SIMMs that can be installed in MCMaster.

Total Memory on	U900 Socket	U901 Socket
MCMaster
4 MBytes	4 MB	none
8 MBytes	4 MB	4 MB
8 MBytes	8 MB	none
12 MBytes	8 MB	4 MB
16 MBytes	8 MB	8MB
16 MBytes	16MB	none
20 MBytes	16MB	4MB
24 MBytes	16MB	8MB
32 MBytes	16MB	16MB
32 MBytes	32MB	none
36 MBytes	32MB	4MB
40 MBytes	32MB	8MB
48 MBytes	32MB	16MB
64 MBytes	32MB	32MB

Note:

∙If only one SIMM is installed on the board, it must be installed in location U900.

∙If 16MB or 32MB SIMMs are used, verify Jumper J801 is connected to 1 and 2.
