Sorry. But it could have been worse... like my random bid from last month. These N501's notoriously self destruct and I don't expect anything less than unrepairable but my offer was so much less than the advertised price I wasn't expecting a yes.
:lol:

Yes, it could have been a lot worse I guess :)

Sometimes you just have to buy stuff when you can, and I've been caught out before by a low-ish bid that I wasn't expecting to win with and there it was, I won.

And with offers you sometimes get a yes when you expect a no.

Nice, I should really get round to upgrading my Sharp 7210 with a 80287 as it's maxed out ram wise and just needs the fpu to complete it.
If it ain't broke, test it to Destruction.
