+*       Analog driver cards:
+        The BP-1200, 1400 and 1600 have up to 6 of these cards in them.
+        Each card can drive exactly 8 pins with analog (pwm-controlled?)
+        voltages. The BP-1200 is probably usable with as few as one of these
+        cards installed, but can only be used with 8-pin devices in that case!
+******************************************************************************
+*       Tech adapters for BP-1148 and BP-1200:
+*       Note: Regardless of tech adapter, only up to 48 pins are drivable with
+         analog (pseudo-dac-per-pin) voltages, the remainder are pulled high or
+         low by the tech adapter.
+*       TA-84: 84 pin tech adapter
+         Rev C: Small board which doesn't cover the whole front of the BP-1200.
+          no screen printing on the case, only identifiable by the pcb marking
+          this PCB can be populated with either 48 or 84 relays; if the former,
+          it is known as an STD48 pcb; the latter is presumably STD84 and may
+          have an otherwise unpopulated PGA FPGA or ASIC on it as well.
+         Rev E: Marked "CPCBTA84V", a larger board which covers the entire
+          front of the BP-1200 including the LEDs, but has its own 3 LEDs on
+          it (why not plastic light pipes?) controlled probably through the
+          93c46 bus. This board again has either 48 relays on it, or 84 relays
+          and an FPGA or ASIC on it.
+*        TA-240: 240 pin tech adapter, this is a full sized shield which
+          like the CPCBTA84V covers the entire front of the BP1200.
+          It likely has even more relays in it, and it provides the same
+          "three" connectors that the bp1400 and 1600 do natively, to allow
+          for 240 pins to be driven. It almost certainly has an FPGA or ASIC
+          on it as well, possibly several.
