Sorry for not providing this info in my post. I have version 8.0 of the museum's documents on a USB flash drive. The file is located in the "Service Manuals & Internals" section with a name of "hp41cpu.pdf" and a path of "/data/cd11/intern/hp41cpu.pdf". It's entitled "HP-41C CPU, Display Driver, HP-IL, Data Storage, Timer IC, and Interface IC Specifications" . The portion mentioning the PUS circuit is in section 5.1.6 . Regards, Jonathan Aeternitas modo est. Longa non est, paene nil. |
