The connector on the 3/50 is certainly VME. http://anduin.eldar.org/~brad/sunstuff/Item_7B_board_connector.jpg - the 3/50 without the memory expansion board, close up of the board connector. http://anduin.eldar.org/~brad/sunstuff/Item_7B_case_connector.jpg - a very bad shot of the case that the 3/50 board goes into http://anduin.eldar.org/~brad/sunstuff/Item_8_board_closeup.jpg - a closer picture of the 4/110. Note the three connectors. http://anduin.eldar.org/~brad/sunstuff/Item_8_case_connectors.jpg - the inside of the 4/110 case -- Brad Spencer - brad at anduin.eldar.org - KC8VKS http://anduin.eldar.org - & - http://anduin.ipv6.eldar.org [IPv6 only]
