Narrative:
While climbing through approximately 10;000 feet; we were alerted to a via (versatile integrated avionics) failure. After checking the QRH; multiple alerts began appearing. I contacted maintenance control and dispatch and relayed our situation. They suggested a return to the departure airport. The alerts continued; and I declared an emergency. We had no map displays; the du's (display units) were flickering; the captains' airspeed indicator was unreliable; the stall warning was going off; no autopilot or autothrottles; and we were in manual pressurization mode. The first officer was the flying pilot and did an outstanding job while I tried to prioritize what we had and didn't have. We landed and after evaluating the condition of the aircraft; decided to taxi to the gate with crash fire rescue equipment trucks following us.it appears the #1 via had a complete failure. The QRH was no help. The level 1 alert only states; 'do not change eis source' and that the fuel quantity comparator will be inaccurate. I feel the QRH should give you a bit more info as to what to expect.
