I bought an IPX in the same condition about nine months ago ... was quite a deal at 500 DM (ca. US$350) :) : The first thing to aquire seems to be ram as I could then use the serial : port as the console. Correct. The IPX has a built-in GX frame buffer, but you'd of course also need mouse+keyboard. : Can it use 4Mx36 - 80ns PC simms? I looked in the archives of the sun-managers : mailing list but there doesn't seem to be a consistant answer. Does anyone : have any experience of doing this? Stnadard 72-pin "PS/2"-type PC SIMMs _with_ parity work in an IPX. Make sure the access time is <= 70 ns. You should be able to use 1Mx36, 2Mx36 and 4Mx36 type SIMMs; I currently use one 4Mx36 SIMM. The IPX actually uses only one out of the four parity bits provided. So, if you find some x33-bit SIMMs (e.g. from an ELC), these will also work.
