Will SIPPs work in an STe? How do SIPPs differ from SIMMs?
If I have 2 1megx8 SIMMs already in my STe, will 2 1megx9 SIPPs work with
them to give me a total 4meg?

They use single in line sockets very much like IC sockes. I did desolder the pins and clean the contacts of some SIPs to make them SIMMs again. They work fine. 9 bit SIMMs are no problem in either MacSE/SE30 or Atari STE. Tried it out. The 9 bit SIMMs/SIPs contain one more chip, but the inout-pin of this chip is not connected to anything in the STE. To be sure, connect the Data 9 inout to a 10 k pullup to 5 volts. This will make the chip read in a 1 on every write and stop it from doing wild things. hase -- Hartmut Semken, Lupsteiner Weg 67, 1000 Berlin 37 hase@netmbx.UUCP Hi! (Zaphod Beeblebrox)

As I understand it, SIPPS are SIMMS with pins soldered on (or the equivalent). On PCs, they are sold as removeable, in STEs they have been soldered in place of the SIMM connectors. The 1Mx9 SIMMS work fine in STEs, but you will have some modifications to make on SIPPS to make them fit. Have a good look at the ones you are considering, if they look as if they are modified SIMMS, and you think that you can reverse the mod - go for it. Otherwise, don't bother. Not too helpful, I know 8-). ciao, Bob Pegram pegram@griffin.uvm.edu or ...!uvm-gen!pegram
