Sorry, no. The 2091 uses a 256k x 4 bit chip. The 2058 uses a 1meg x 1 bit chip. Same size different organization.

Hard to say in Yugoslavia..  They're long obsolete everywhere. You could try someplace like Digikey, or a european equivalent. I'm not familiar with the electronics shops on that side of the pond.

Looks like 18 pin DIPs. Tyr here

for a picture of the board.
I looked at DigiKey, and they don't have the chips.
