I used to have one like that, and I may even still have some SIPPs --
but they would be 256K SIPPs, which you probably don't want. However,
you do realise that SIPPs and SIMMs of the same size (capacity) have
exactly the same pinout? You could either tack pins onto SIMMs (I've
seen it done) or fit a SIMM socket to the board, if the spacing between
the SIPPs is standard. I may also have some 1MB DRAM. What pinout and
config does your board need?
