I have a DTK computer. It's a 25MHz 386. The model number seems to be KEEN-2503 or something like that. I am trying to install a Cyrix 83D87 coprocessor. When I place the coprocessor in the 121-pin Weitek socket (the Cryix is supposed to be able to go in a Weitek socket or a 68-pin 80387 socket) the machine will not boot up. The BIOS setup says that the coprocessor option is set to autodetect. My questions: 1. Does anybody who has a similar DTK machine know if there are jumpers or other settings that need to be changed when installing a coprocessor? 2. Some computers have 2 sockets: one for a Weitek and one for a 387. I saw only a Weitek socket. Is there a 387 socket hidden somewhere (under the hard disk maybe)? 3. Anybody know a tech support line for DTK? TIA, -- E.
