There is hardware for running an HP signature in the 9010a. I found this in the service manual (page 4 of 4 of the main board schematic, or something like that, there was no page number). Included in the calculation was a counter that counts the number of high to low transitions made by the incoming data bitstream.
Is this the Async clock module? (where you looking at the PDF from spies or do yo have a schematic?)
Yes, the one from spies. It's a small circuit all by itself on the page, and the bottom right corner of the page says "sh 4 of 4". You can recognize it by all the xor gates. -Zonn
