So, when first I posted this, I (and others in the forum 😉 ) assumed SIP memory for this board:

But a little zoom around the RAM area - and a photo from the manual makes me think otherwise .. What do you think? Is it "just" 30 pin SIMMs with pins on both sides, or are the two rows actually for 2 separate modules - or should it, as the manual implies, be filled with DIP memory chips? And in that case - HOW?

On the other hand, the jumper designations doesn't match and there are no jumpers near the 287 socket either ..

You can have total of 8 SIP memory modules there. They are like SIMMs, just with pins. I think, you can even solder pins on SIMM module and it works.

But would there be room for actually putting a module in each of the two adjacent rows? I mean, with the size of the memory chips, I wouldn't think they could sit there?

Each SIPP socket has pins labelled 1 through 30. Clearly it's not for DIPs, because 30 is not divisible by 8 or 9 (the number of legs per side on memory ICs typically accepted by 286 systems). Although it's tight, there should be just barely enough room to squeeze the SIPPs in there.

Well, only one way to find out 😀 after sorting out that Varta plague, that is ..
