I have a NEC PC-9801 DS2 with 640 KB + 4 MB RAM = 4'6 MB.
I've read here
http://www.pc-98.jp/htmls/1800000006199.html that this PC-9801 model can be upgraded to a maximum of 14'6 MB RAM.
The problem is I don't know which RAM type this computer uses (EDO 60NS, EDO 70NS, FPM, ...).
And another question:
Will the computer RAM be upgraded to 14'6 MB correctly if I connect four EDO 60NS modules of 4 MB each one? or do I need to put necessarily three 4 MB modules and one of 2 MB? (having to buy a 2 MB module separately will be more expensive for me).
