Amiga 500/+ 2MB RAM expansion
« on: May 16, 2023, 01:30:56 PM »
If somebody could send full BOM list for this expansion RAM.
I see the RAM chips 514256 4-bit x 256K by Vitelic.
>2 x capacitors on board
>8 x little capacitors
>4 x SIL8/ RESISTOR ARRAYS

and connector , of course.


Board is without clock module for Amiga 500 /512Kb
This version fitted for A500+ 1 MB RAM Expansion.

This expansion board is probably manufactured by AlfaData.

the caps close to the ICs usually are 100 nF (104). The resistor array should be 47 ohm (based on my RAM expansion). The electrolytic I don't know, but probably a 10 uF should be ok.
