Hi Group: I am in need of an M7891-DB or similar memory board for my pdp-11/34A. The specs on this memory are: 128 Kword, 18 bit, parity RAM. Size is not important in this case, I'll take a compatible board with less RAM on it. Please reply to the news group. list, or to me directly. I have stuff to trade or will purchase if necessary! Thanks, Kevin -- Kevin McQuiggin VE7ZD mcquiggi(a)sfu.ca
