Looking at shematics in: http://www.modtronix.com/products/prog/pickit2/pickit2%20datasheet.pdf Some notes: - if VDD_TGT is off, AUX, ICSPCLK, ICSPDAT are turned off by PNP transistors Q2, Q3, Q5 resp. (check again!) - board has two 512kbit eeprom chips: 24LC512 http://www.microchip.com/wwwproducts/Devices.aspx?dDocName=en010828 - target voltage is generated with PWM through a 10K / 0.1u filter, followed by 2x gain amp. this can then be switched to VDD_TGT, which is also fed back to analog in (straight). - VPP pump is driven by PWM with a 1/3 feedback into ADC. can be enabled to VPP, or VPP can be pulled down to perform reset. - there don't seem to be any hazards. Seems like a fun project to try to get this going. Maybe together with the non-documented debug modes?
