So i'm looking at my current RAM module sitting in my newly acquired 486 - the sticker reads Legend and there are 8 Alliance AS4C14400 chips. Memory test shows i have 4096kB of RAM. Manual to my mobo (zida tomato 4dps 2.11) says it supports the following :
The system board supports flexible SIMM configuration:
· Flexible memory bank location and size.
· Accept 2 pieces of 72-pin SIMM sockets, SIMM 1/ 2, total 2 banks.
· Support SIMM type: 1Mx36, 2Mx36, 4Mx36.
This is what i have:
Since it's been 30 years already since i was fiddling with these systems i don't recall all the do's and don'ts so please help me a little here.
1) Can i combine RAM sticks with different sizes ? I'd like to buy one 8MB module so I'd have 12 MBs in total.
2) I read about EDO and FPM types - i don't recall those abbreviations from my childhood. Which one do i need to order so it gets along with my current RAM module?
Thanks in advance, i'm sure i will have more questions 😀
