Back when the GS was first released, I seem to remember seeing that the Apple Memory Expansion card for the GS could be used to add either 1 meg or 4 megs of memory, while third party cards would add much more.. Well someone has now asked me how they can increase their Apple card from 1 meg to 4. Simple I thought, just replace the 256k chips with 1 meg chips and presto.... But wait a second, the first 8 chips are soldered in.... can any of the DTS folks supply a helpful answer please? How does one make the memory card into a 4 meg card??? Many thanks in advance for your help! bsherman@ibiza.cs.miami.edu or bsherman@mthvax.cs.miami.edu bsherman@pro-exchange MCI Mail: BSHERMAN

I have a two meg Checkmate GS RAM card, with four banks of 256k chips and 1
bank of 1-meg chips. In other words, I have a card that has mixed chips on
it. I had quite a few compatibility problems with these mixed chips until I
got a new motherboard (I had one of the original Woz limited edition logic
boards). Now that I have the new board, my problems are solved, but I
wouldn't recommend this card to anyone unless they purchase it with the chips
directly from Checkmate.
However, the one meg chips are larger than the 256k chips; you can't just
replace one chip size for another.

Network Comment: to #11542 by dlyons@apple.com Yes, the Apple Memory card is limited to 1 Meg. However, there are third party cards that offer up to 4 Megs. Now if Apple would just switch those GS's to SIMM bank memory...

Yes, in fact MDIdeas's OctoRAM supported 8MB on one card using 1Mbit SIMMs. Somebody told me that MDIdeas has gone out of business; is that true? Is the OctoRAM still available from some vendor?

MDIdeas has not gone out of business, as far as I know. I have an OctoRAM card from them that was purchased in June. Strange that they no longer advertise the OctoRAM, nor do most mail order places carry it, but I've got one, and it has 4 meg on board and performs flawlessly. We still have dealerships that stock their other products, so I think news of their death is a little premature. __________________________________________________________________________ |Disclaimer: Segmentation Fault: Core Dumped. | | | |Internet: REWING@APPLE.COM-----------------------Rick Ewing | |ApplelinkPE & MacNet Soon!------------------Apple Computer, Inc. | |Applelink: EWING--------------------100 Ashford Center North, Suite 100 | |Compu$erve: [76474,1732]--------------------Atlanta, GA 30338 | |GENIE: R.EWING1--------------------------TalkNet: (404) 393-9358 | |USENET: {amdahl,decwrl,sun,unisoft}!apple!rewing | ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
