I'm looking for an 8087 Maths CoPro as all the ones I can find on eBay seem to be Chineseum and possibly fake.

If anybody has one spare, please let me know. The CPU is an NEC V20 as that may make a difference...

Unfortunately I can't see that here in the UK, are you able to share the price please?

Thanks

There's this eBay listing: https://www.ebay.co.uk/itm/324901073436 ... R9Cl1N3wYw

Thanks, I had seen that one and other similar ones, I just feel the price is a bit steep, but I'll keep my eyes open.

@rubber_jonnie

Yes, the price is £34, with delivery included in Japan.

Thanks. Similarly to the one @stephen_usher pointed out on eBay, the price is a bit high, and if that only includes delivery in Japan, it could get expensive to get it to the UK.

Am I just being too sensitive to price? It seems a lot really when you compare prices with similarly old ICs.

You would have thought that they would be more plentiful and hence cheaper, but obviously not. Maybe most of the XT class machines never had one fitted and hence few have gone into the reused circulation.

@rubber_jonnie
@stephen_usher

I would say it is a reasonable price for this quite rare FPU.

@stephen_usher
@HigashiJun

I think probably you're both right and if I want one I will have to swallow the cost. Better have a think about how much I really want one...
