Hi Ian I'll give a look if I have also ther simm ram 30 pin ..... but now I'm also not sure if I'm using 1Mb or 4Mb simm ram .... The ram used have 6 chips : 1 chip is TC514400JL-70 (for parity ?) 5 chip are TC511000AJL-70
Is there an homepage to know exactly if the simm ram is 1-4-8-16-32 ....etc.... Mb ? and also if it has fast page, parity ..... ?
