The inside of this WJ-8716/MFP is almost identical to the inside of the rest of the radios in the series. The extensive front panel controls of the MFP option require the addition of the two long cards in the microprocessor bay (second from bottom) and a special front panel card in the narrow bay behind the front panel.
There are two very different versions of the MFP option. The difference can only be identified by looking at the the MFP cards in the microprocessor bay. The older MFP has an A3 card # 796022 and an A4 card # 796029. The newer MFP has an A3 card # 796308 and an A4 card # 796275. The cards in the different versions are radically different. For example, the microprocessor in the older version is on the A3 card. The newer version has the microprocessor on the A4 card.
The MFP manual only covers only one version. Check the numbers on your A3 and A4 cards in your MFP radio before you order a manual. The MFP manual also includes manuals for the 232M and 488M options, which are often found in MFP radios. This unit has the 488M option, which is the third card in the processor bay (shorter, in between MFP cards, with cable running to rear panel).
A closer look at the top bay reveals a bulge on the input converter. This is the special 100 kHz wideband input filter for the special WB SMO option.
