Todd, I found this in my old '01 mail archives for what it's worth. Micron Technology The specs are as follows: 168pin DIMM Gold Pin Standard ECC Pinout 3.3v Buffered EDO 60ns 8x72 The 64MB Sticks we own are Part Number MT9LD872G-6X The step up 128MB Sticks we require are Part Number MT18LD1672G-6X View this PDF for complete Technical Briefing. http://download.micron.com/pdf/datasheets/modules/DM77_2.pdf They do have a different chip layout but I've tested as best as possible and found that it should be okay. -- Adam -----Original Message----- From: usr-tc-bounces+adam=semo.net@mailman.xmission.com [mailto:usr-tc-bounces+adam=semo.net@mailman.xmission.com] On Behalf Of Todd Sent: Tuesday, April 04, 2006 11:13 AM To: berto@core.com; 'Discussion relating to the 3Com/US Robotics Total Controlmodemsystems.'

Hello everyone,

Can anyone point me in the direction of finding some literature on the memory requirements for the various software revisions. I've looked in the pdf's for those revisions and I don't see anything regarding the memory requirements, only what revision the other cards should be running at.

I'm looking I believe at TCS 4.5

hiperNMC = 8.6.3 hiperARC = 5.3.3 hiperDSP = 3.5.12

Thanks in advance,

Todd
