ram chip crossreference?

I'll make a general offer to the whole list, 256k Simms for 1.2 * shipping (shipping is actual postage plus $1 for a box or padded envelope if the shipping method doesn't include it like priority mail does) (please ask for just what you need) 1 MB simms 4 matched/$3, 8 matched/$5 plus shipping. No applications research available at these prices, but I will check for speeds. BTW I'm guessing the list has some people besides myself pulling parts. Recently I have started pulling chips off boards and dumping them in a box. Mostly memory stuff I hope to use on underpopulated cards of my own, but I suspect that if people make requests to the list, parts may be found. Related to the chips, AAAArg, bought some cards a couple weeks ago and the scrapper had cut the fingers off half a dozen nice cards, Corvus workstation cards, Z80 cards, etc. OTOH I have a few Z80A chips in my parts box now.
