I'm trying to build an 8570-A16 machine and max it out with 16mb ram. Should be fairly easy as I'm swimming in 4mb SIMMs with IBM branding. Machine reportedly needs 80ns parity ram.
Problem is that when it's not giving a 2xx error (mainly 211, 216 and 225) with whatever memory I choose it's only declaring each stick to be 1mb.
EG: I have two sticks loaded with eight HM514400BS7 4mbit DRAM chips. Rates 70ns. Pop one in and all it sees is 1mb. Pop both in and now it's 2mb.
I also got other sticks with similar 14400 markings on their chips (A14B00J2x, TP104400J2C etc.) and they all also read just 1mb. I don't get it.
