Will you be able to use 4 of these on the same motherboard? Will four of these modules placed in adjacent or adjacent +1 slots fit parallel together?
... says the forward thinker.
You're right, four of these identical SIMM banks will impede the next one adjacent to it.... typically these come in sets of four (labelled A, B, C, and D) with two of the units (A and B) having a higher designed PCB to rise above the SIMM bank next to it. Though unfortunately while on a trip in the US (during my SIMM project too!) I could only find a bunch of (C and D's) NOS... they are mirror opposites to each other, once inserted... they face away from each other.
To get around the missing (A and B) I have found a couple of 30 pin pass-through risers with no components on them that lift only the SIMM banks up above the unit installed next to it.
I've tested two of them each on a 16-bit 286 and they work fine, getting four to go together (i.e. 32-bit) is still WIP... my work and a young family take all my time at the moment and have put all my projects on hold, but I aim to complete this project before all others.
