I have a 2meg card kit .with memory chips on board 16x1000ap-80. you need to know how to solder. 16 dat lines and Address line 9 from the memory controler chip. its directly next to address line 8 the rest is plug in. it gets its power from the videochip section under the shielding .just remove cover.
and remove chip..plug in kit..and put chip on board kit socket. also gets all the address lines 0 too 8 from the same plug.
you now have 2.5megs
randy.viau@sympatico.ca

think the kit was $30 unpopulated.
chips are impossable to get now.. i paid 1 doller each. $18...something with tax.
never got around to use it.
WILL SELL for same. plus 9.90 shipping.CAN
