RE: Hand Held Products 71M/M eprom carrier question
I'm not sure this is of much help, but here are a few observations about this 'other' style of carrier:
There is "(C) 1984 HHP Inc." etched on the board. (the normal board has only "HHP Inc.") It appears the 2 pins on each side of the top of the chip carrier (is that pins 1 and 15?) are connected by a common run to the top lead of both of the 2 transistors and next to these there is a label on the board "T/C" and immediately below the T/C it says "1V" The 2 inner pins of the 2 pairs of jumpers are connected together and that is connected to the 2nd pin down on the right (pin 16?) Sorry, that's not probably using the correct terms, etc. but maybe it helps to answer about 64KB support. --Bob Prosperi |
