I have not opened up ours yet but I always assumed they were all DEC
boards.

m having trouble trying to identify the correct module number suitable for
the LSI-11 CPU. Even though it’s a Heath machine, I assume it’s module
compatible with DEC. Any help would be appreciated. Thanks!

Maybe an M8044 MSV11-D (no parity) or M8045 MSV11-E (parity) would be
most appropriate. They came in 4KW, 8KW, 16KW, and 32KW flavors.

Fairly common on eBay.
