Need help with an Infotek memory card

Hello, I have an HP 9816S with an Infotek Systems memory card in it. The card is either misconfigured or defective, because I get the classic "memory missing" error on startup. Anyway, I'd like to find out whatever I can about this card, especially the jumper and DIP switch settings. It's the standard HP 9000 Series 200/300 expansion board, with "Infotek Systems AM 210 Memory" silkscreened on the PC board. There is also a label applied to another part of the board that says "AM 242". It has a four position DIP switch that I assume is to set the memory start address, and another set of four 2-position jumpers located adjacent to the DIP switch. It has 32 sets of 22 pin in-line sockets for memory modules, and there are 16 of these sockets populated, each with a module containing four 256 Kbit chips. The modules are paired up, so that sockets 1 and 2 are occupied, 3 and 4 are open, 5 and 6 are occupied, etc. Counting all the bits suggests to me that there are 2 MBytes installed on this board, with room for an additional 2 MBytes. Is Infotek Systems still around? Last I heard, they were in Anaheim, CA, but I can find no listing for them. Any and all help is appreciated! Thanks, Stan
