It took awhile, but I got some more info on the Sunpak PZ 5000AF.
Went to a "Camera Show", where you can buy, sell, or trade. Someone there had the Flash unit with the Minolta (MX) owner's manual for sale. I told him that I have the same Flash and was looking for a manual, but he wouldn't part the two. He did however, let me take some shots of the pages, and write down some info.
So O-K, here goes:
The Sunpak PZ 5000AF is designed for Minolta a-i, (The 'a' looks like the "Sony" 'a'.), -si, and -xi series AF Cameras.
Auto/Manual Power Zoom from 28mm-135mm. A large backlit LCD Panel (20 seconds duration when Lighted).
Offers both the ADI Flash Mode and TTL Auto Flash Mode, plus TTL Wireless Mode, and "Auto Sensor Mode'.
"MULTI" Flash Mode provides a 'stroboscopic' effect. A 19 Position stepped Light Output from 1/64 to Full.
Rear-Curtain Sync Photography, Flash Unit Slave Function, and a "Automatic shut-down/Standby" Function.
The PZ 5000AF Flash has an ISO (Film) Speed Range from ISO 6 to ISO 6400.
Use 'AA' Alkaline or 'AA' rechargeable Nickel-Cadmium (Ni-Cad) Batteries. NOTE-Do Not Use Lithium Batteries.
Can use External Sunpak Powerpack NC-510 or TR-PAK II.
The ADI Flash Mode can be used, when this flash unit is used with a Camera equipped with the ADI flash function, and a 'D'-type Lens has been mounted on the Camera. Install the Flash on the Camera, and push the (MODE) mode-switching button until the "A TTL" signal is displayed on the LCD Screen. When in ADI Flash Mode, the flash's built-in computer calculates the Aperture (F-number) and ISO (film) speed from signals from the Camera, and the optimal distance of TTL flash will be displayed. The optimum distance will not be displayed unless the Shutter Button on the Camera is pressed 'lightly', or until the ready "OK" signal appears. The Distance will be indicated on a Bar Graph, ranging from 0.5m to 32.0m (1.6ft to 105.0ft).
Differences between Sensor-Monitored Flash Methods in the TTL modes.
ADI Flash Method- In this sensor-monitored method, a monitor flash is fired just before the strobe flash goes off. The results of this photometry, and the distance data from a D-Type Lens, are then used to set the intensity of the actual flash at the optimum value. This method can only be used with Camera's that are equipped for ADI function with a D-type Lens attached.
TTL Flash Method- The Flash is set to achieve the optimum exposure, for the object or subject being photographed, at all times. Since the Brightness of the Background is not factored in, the object being photographed may stand out too much, depending upon the amount of ambient light, and the shooting conditions.
Hope you find this information helpful.
