Motherboard Schematic Drawing Errata - someone - 11-10-2020
On DRG No: 1248-1-06
IC17 XORÂ gate with inputs on pins 12 and 13 and output on pin 11 is incorrectly drawn as a standard OR gate.
This error was fixed on DRG No:1248-6-06 but remember 1248-6-06 contains additional circuitry (the deflicker and RTC circuits).
On both DRG 1248-1-06 and DRG 1248-6-06
IC16 82S123 PROM is missing the not connected pin 4 output.
