ok, here you go:

1Mx4 DIP        SOJ     ZIP
1       DQ1     DQ1     /OE
2       DQ2     DQ2     /CAS
3       /WE     /WE     DQ3
4       /RAS    A9      DQ4
5       A9      A9      VSS
6       A0      NO PIN  DQ1
7       A1      NO PIN  DQ2
8       A2      NO PIN  /WE
9       A3      A0      /RAS
10      VCC     A1      A9
11      A4      A2      A0
12      A5      A3      A1
13      A6      VCC     A2
14      A7      A4      A3
15      A8      A5      VCC
16      /OE     A6      A4
17      /CAS    A7      A5
18      DQ3     A8      A6
19      DQ4     NO PIN  A7
20      VSS     NO PIN  A8
21              NO PIN
22              /OE
23              /CAS
24              DQ3
25              DQ4
26              VSS

These pins are numbered from 1 to n regarding to their specific package.

Enjoy,
