Help finding video RAM for Realtek ISA VGA

Postby BSA Starfire » 2017-11-29 @ 09:21

Hi Folks,

I'm looking to buy the two memory chips for this Realtek ISA VGA card to take it up to the full 512K(basically so it can do 256 colours in Windows 3.1). Anyone know of a reasonably priced supply? I'm in the UK,if that matters.
Thanks in advance.
Best,
Chris

Look at the reference of the chip that are soldered on the circuit right next to the sockets, they must be the ones you need. Though I won't recommend this card for 386/486, realtek video cards were cheap and slow.

4256-100ns or faster are really common. I've got dozens of those, but I'm not in the UK.

I know the Realtek is VERY slow, but that is fine for it's intended use/system.

Is this the right stuff?
