I found two "new" Multibus cards in the last couple of weeks. The first was made by Monolithic Memories and appears to be a RAM/PROM card. The intersting thing about it is that it has three Dallas battery backed NV RAMs and two RCA 62256 SRAMS. Another oddity is that it has cutouts along the top edge, probably for some type of I/O connectors. <http://www.classiccmp.org/hp/multibus/mmi%20mm8800.jpg> The other card is a video card made by Matrox. Everything on it is TTL except for one LSI IC marked MCH-01. Anyone know what that might be? There are four other blocks on it that appear to be LSI ICs but it turns out that they're really DIP switches with covers on them. There is one in the top LH corner with not cover. <http://www.classiccmp.org/hp/multibus/matrox%20msbc%2024-320.jpg> Does anyone have docs for either of these? Joe
