Buzzkill, the EOS reports itself as parity, so the system in question
has to support 16MB parity SIMMs.

4MB and 8MB EOS are supported by all PS/2s, as their size is supported.
The IBM ECC-on-SIMM (EOS) part numbers are

The following memory options complement the Options by IBM family of offerings:
4MB 70ns ECC-on-SIMM Memory Upgrade
8MB (Wide) 70ns ECC-on-SIMM Memory Upgrade
8MB (Tall) 70ns ECC-on-SIMM Memory Upgrade
16MB 70ns ECC-on-SIMM Memory Upgrade
32MB 70ns ECC-on-SIMM Memory Upgrade
The IBM ECC-on-SIMM Memory Upgrades offer 4MB, 8MB, 16MB and 32MB of error-correcting-code (ECC) memory on a SIMM. This upgrade family -- a plug-compatible, fully retrofittable series of 70ns memory modules --
allows you to upgrade a parity system to a fully functional single-error-correct (SEC) ECC system. The ECC function is completely self-contained on the SIMM and provides correction of single-bit errors
that
occur in each byte of SIMM data. No processor changes are required to
receive the enhanced reliability this SIMM family offers.
The ECC-on-SIMM Memory Upgrades are organized as x36 bits, support
parity, and are packaged on a 72-pin JEDEC (Joint Electronic Device Engineering Council) standard SIMM with gold tabs. The 4MB SIMM has IBM
presence detects, while the 8MB (Tall and Wide), 16MB and 32MB SIMMs
have industry standard presence detects.
Use of the ECC-on-SIMM Memory Upgrades is recommended when processing critical applications on systems without native ECC. Enhanced data
integrity and memory reliability are provided with no system performance
penalty. The upgrades are extremely important in server environments
where single-bit memory errors can impact all users on the network.
