This book covers the "Black & Gray Boxes" used in Seeburg models from 1969 to 1977: The digital credit and selection system. Seeburg called this new system "Microlog System" - short for "Microscope Logic". It meant that the circuits only could be seen underneath a microscope. Electromechanical faults caused by switches, contacts and moving parts in the credit system were eleminated by using chips.
Tony Miller's writes: "While working on my B.S.E.E., I was employed in Seeburg's Quality Assistance Departement where I repaired more Black and Grey Boxes than I'd like to count. Since their inner workings was a well-kept secret and I was not on the distribution list for documentation, I had to teach myself how the three custom chips work. Because of this. I know how difficult it is to fix one of these boxes without the proper support. This manual addresses that problem, and you'll be able to keep your machine working for a long time to come."
Seeburg never published any detailed information on these Black & Grey Boxes. Those needed had to be returned to the factory for a repair. But today Seeburg does not exist anymore and technicians have to repair by themselves. This book is a complete description of how the Black and Grey Boxes work. They include simplified logic and timing diagrams of each of the three custom chips (two in the Black Box, one in the Grey Box) plus the pricing board setup information, for any machines still using coins. These units were used in these models:
- Apollo (LS3)
- Bandshell (USC1) and Bandshell Firestar (USC2)
- Olympian (SPS 160)
- Matador (SPS2)
- Regency (FC1)
- Vogue II (STD 160), Entertainer (STD2), Sunstar (STD 3) and Mardi Grass (STD4)
- Hutch (FC2)

This 3rd edition includes a chapter on the Seeburg Remote Translator (SRT1), an optional accessory used to permit the SC, SCH Consolettes and 3W1-series wallboxes to work with these machines.
