- What do you mean with extra fast ram? If it is a true fast ram ($20) it

- from internal expansion as a chip ram, but the rest of chips on expansion
- card (if installed) may not be used anymore. There is one internal expansion
- sold here, which enables using 2 Megs of internal slow-fast ram AND 1 Meg
