I just got a memory board for my HP IIIp. The board only has 2MB on it,
but there are 2 rows of empty 20-pin sockets that lead me to believe
I can add another 2MB for a total of 4MB.
I'd like to do that in the most cost-efficient way possible.

The board is marked "(C) 1991 Pacific Data Products" and "P/N 012186".
The soldered-in RAM is mostly marked "HY534256S-70", although three chips
are "HY534256S-80"(?)

Thanks in advance.
