I wish to upgrade my 520STFM to 1M by adding 16off 256k*1 DRAMs. My questions are:- 1/ Are nibble mode rams acceptable? Ie does the ST use the page address mode of vanilla DRAMs? 2/ What other things do I have to do besides putting in the DRAMs? There are 3 spare spaces for resistors near the DRAMs which I guess are for RAS and CAS (2off). What value resistors? Are there any chip selects to be changed? (There are some chip select links near the boot-ROMs -- but are they anything to do with the RAM?) (I assume I will have to put in the extra de-coupling capacitors :-) Thank you, Brian Woodroffe. e-mail == bww%hpqtdla@hplabs.HP.COM
