Internals

The CPU in the AFG5101 is an Intel 8085, the GPIB interface is implemented using an Intel 8291.

The backplane connectors used in this unit are DIN41612, or Eurocard connectors. The required extender cables can be easily made up using these connectors with ribbon cable to allow for adjustment and calibration.

+The backplane connectors used in this unit are DIN41612, or Eurocard connectors.
-The front display uses a blue electroluminescent panel for backlighting, which is usually almost completely faded and dim by now, and the LCD contrast is usually quite poor too.<br>
+The required extender cables can be easily made up using these connectors with ribbon cable to allow for adjustment and calibration.
-A standard cheap 5-volt Hitachi chipset compatible LCD module with 'parallel' interface can be used as a direct drop-in replacement with the removal of the EL inverter from the rear of the front panel PCB, and the LED backlight to be wired to the supply side of the now-removed EL inverter. Top pad is +ve (to anode). bottom pad is -ve (to cathode).<br>
-The new LCD may be 2mm thicker than the original LCD, this can be adjusted for by replacing the original 8mm tall brass standoffs with 6mm tall replacement standoffs.<br>
-If the contrast is too dark on the new LCD, the contrast pin (third from the left) on the header connector from the front panel PCB to the LCD PCB can be removed entirely, and the connection made with a 3.6 kΩ resistor around the edge of the PCB's. This (or a similar value) should bring the contrast back to center scale.<br>
-To adjust the contrast and turn the backlight on and off, press <SPCL>, then <2> <2> <0> followed by <ENTER>. The contrast can be adjusted using the up and down arrow keys and the backlight turned on and off using the <ENTER> key.
-The RAM backup battery is another common point of failure, this was originally a Renata 125-1 3-volt primary cell in a potted enclosure with two diodes.
-A replacement can be replicated using a CR2032 cell and two 1N4148 diodes as used in the original part. See images below for the schematic of the original Renata part.
