REACHING ALD PAGE 83 IN THE SECOND PASS
This has me past the CPU logic sections BB, DN, DU, KA-KW, FA, MB-MC and starting on the major registers now. These are RA, RB, RD, RN, RQ and RS. Once the registers are complete, there are a few pages in the WA and WZ that simply tie signals from storage and SAC, the remainder of the work will be the device controller pages XC, XF, XG, XK, XP, XR, XT, XW and FR.
Total of 5,413 entries, before removing duplicates. Moving a bit slower than I estimated.
ANOTHER CAUSE OF DUPLICATES IN THE DATABASE WAS IDENTIFIED
Some SLT cards, particularly the large double size boards that were developed specifically for the 1130 and 1800 systems, pack so much function into one card that they are covered across multiple ALD pages. Some signals are therefore duplicated even though there is only one pin connection physically. As an example, the -DC Reset signals may be shown on all the pages of a board but it is hooked to a single pin. This gives me multiple entries for the same pin.
