Need help with "unresponsive" Teletek FDC-1C all in one computer-on-a-board.
I've already e-mailed Arthur S., but thought this can't hurt. My Q&T turned out to be just a branded case, the "CPU board" turned out to be this Teletek FDC-1C, and I cannot wake it up.
I am hopeful it is my own ignorance keeping me from getting some response from it.
Power supply was tested component by component, and then the wiring, drives and motherboard were all checked out for proper voltages, floppies are Qume DataTrack 842 and they both turn smoothly if somewhat noisily, main AC motors. There was a Compupro RAM 17 installed as part of the deal, but I took it out in case there was an interrupt situation. This board is supposed to at least boot with its minimal on-board RAM.
Monitor, a VT-520, with an old PC keyboard, is fed from J1, a 20 pin header to D-25 connector on Ser.1 Floppies have the wide ribbon 50 pin header > to edge connectors on drives.
I've been through the monitor setup and tried several different combinations, but so far the CPU does not hear me or refuses to speak back. The only thing that happens when I twist the ignition key is a single variable special character, letter on the monitor, and a backward question mark when going off. I assume this is just the monitor seeing some voltage.
Ideas?
T.I.A. for any input, including noob-bashing, if it is even the least bit educational!
