Re[2]: 9316 rom adapter.

In Bally games they used the letter at the end to identify the type of Chip
Select. So you get 9316A, 9316B or 9316C. The B tended to be the same as a
2716 as I recall. 9332 was the 2532 equivalent, and had similar
labelling-used in Gottlieb pins.

This has wandered a bit away from Vector discussions, but the ROM family is
the same, and perhaps used similar letter suffixes to show the selects.
