487SX FPU coprocessor / SX replacement

[Arbuthnot]

For sale, one 487SX floating-point / maths coprocessor for upgrading a 486 SX with a 169-pin expansion socket. I bought this as new old stock and it certainly appears to be unused. Fully tested in my IBM Valuepoint but I've now upgraded to a different motherboard with a faster CPU so I don't need this. Looking for £40 plus UK shipping is about £4. First sale post so I hope I've done this correctly.
EDIT price drop
EDIT sold externally
