Recently bought a pile of old ISA cards for a few euro because a mint condition Gravis Ultrasound rev 2.4 was amonng them :D
Along with the cards I got a very early 386sx motherboard from NEAT, it only takes sipp memory and has room for four of these at the bottom.

Does anyone here have some spare one's for sale?

I've got quite a few still here, think they are 1mb each, no sure if they are with or without parity but I suppose I can check. Let me know if you are still looking for some.
 
Can you post a photo of your motherboard? I think the early SX motherboards are pretty interesting. Sometimes they have cache, removable CPUs and other expensive stuff you might not find on a typical SX motherboard.
 
It's the standard 386 core with external data bus restricted to 16-bits, and memory addressing limited to 24-bits. Except for military versions, was only available as low cost non-removable QFP. Basically a 386 designed to sit on a 286 planar.

Got two 2mb sipp's from a kind soul at english amiga board but can't get the board to boot..no boot with removed sipp's either
I'm afraid this board is dead

The 2x 2mb sipps are installed in bank 0 & 1 here
 
Now that's an old 386SX board! I think this must be the first one I've seen that used DIPs for memory. I've seen DIPs on lots of 386DX boards, but the 386SX came out later so it's less common for them.

It seems odd that it would be dead. Boards like that are usually pretty hard to kill. Try removing the coprocessor and the DIP ram, and configure the jumpers to just use the SIPP ram. If that doesn't work, you probably have some bad tants.
 
Looks like you're missing a clock battery. I have the same motherboard and my clock battery leaked and ruined it. I believe it's an axial type that goes in that empty spot next to the keyboard connector.

If you replace the battery, it might work. Also look for damage to the traces on the motherboard from a previously leaky clock battery that may have been removed.
 
NEAT Chipset?

I remember that for 286's, they had some extra memory management possibilities. But then, as this is a 386, that is not an issue anymore.
 
I noticed an empty crystal/oscillator socket OSC1 on the picture, should something
be plugged in there ? Do you get any output at all on the screen or beeps through the speaker ?

Managed to get some memory for the board but sadly the board is dead :(
