[cctalk] Looking for EPROMs

Looking for MCM68764 and I could probably use some TMS2532 as well. I'm also always on the lookout for blank bipolar proms (chips stargin with 82S, and compatables). Anyone have any of these they don't need. New, used, needing erasing, doesn't matter. If you have any, let me know how many you have (of each if you have both type) and what you are looking to get for them. If you need more standard/bigger EPROMs, I can trade too.... have a number of 2764, 27256, have some 27128 I think too, and maybe some 27512 ? I'd have to go digging. Thanks, -- Curt
