I own a relatively old PS/2 model 80-4016 which means it has a 40MB HD and is a 16 MHz 386 MCA bus machine. It has 1 MB RAM on board and 4 MB on an INTEL ABOVEBOARD MC32. My questions are: 1) where in the tower case do I look to see if there are anymore SIMM slots to be filled on the mother board? 2) near the very top of the case there is something that looks like a small half card that plugs into a port (NOT an MCA or XT bus port but rather with a bunch of male pins. Underneath it is another port which has nothing attached to it. Is this the actual main memory for the machine? The small rows of silver square blocks are not SIMMs but what are they? 3) Would it be possible to buy 2MB or 4MB SIMMs to replace the ones in the machine now? On the motherboard not the INTEL card.

This is the motherboard memory. The Model 80 did not have SIMMs SIPPs, etc. but rather large memory cards. These memory cards fit into either of two connectors on the motherboard just above the MCA slots and below the power supply. You will be able to use the 1 MB and the 2 MB cards in the 16 MHZ Model 80, but not the 4 MB cards. The 4MB card will go in the 25 MHz Model 80, but I'm not sure about the 20MHz & the 4MB card. This gives you a maximum of 4MB on the motherboard. >3) Would it be possible to buy 2MB or 4MB SIMMs to replace the ones in the > machine now? On the motherboard not the INTEL card. Yes (2BMB) and no (4MB). hh -- Harry Haas GTRI/RIDL/DB "What makes it DO that!?" - Bones Georgia Institute of Technology, Atlanta Georgia, 30332 uucp: ...!{decvax,hplabs,ncar,purdue,rutgers}!gatech!prism!hh2 Internet: hh2@prism.gatech.edu hhaas@{gtri01|rmadsun}.gatech.edu

The motherboard does not take SIMMs. > 2) near the very top of the case there is something that looks like a small > half card that plugs into a port (NOT an MCA or XT bus port but rather > with a bunch of male pins.

IBM memory modules. Third party suppliers (e.g. Kingston) do these boards at a reasonable price. Don't know about the 80-041 but in my 80-111 this memory is faster than the bus memory. > 3) Would it be possible to buy 2MB or 4MB SIMMs to replace the ones in the > machine now?
