Thanks for all the help!!!
I just checked it--about 20 mA. Interestingly, the reader is now working! I had to put the machine away so I can use my bench for work over the weekend, so I assembled the whole unit, and popped in the battery I bought (from Mark via Ebay), and just for kicks, I slid a card in and it went through smoothly this time, but gave an "ERROR". I wondered if perhaps the card contained garbage data, so I tried the Diagnostic Card from the Standard Pac, and it read both sides, then wrote both sides of that same blank card, then read the card back. I ran the program, and it gave me the -7.777777770-77 as expected, and printed out 1.+07, 10.000+06***, 1.0000+07***.
However, the manual indicates it should leave a -8.888888888-88, and instead I see 1000000.00
I am assuming the last is a display test. Why would the calc not show it?
Also, I notice that the printer paper tends to jam a bit while loading. I had to thread a piece of tape beneath the platic sheild to try to fish the leading edge of the paper up and through. Afterwards, it seems to feed along nicely, although the printer makes a bit of a whining sound.
All the keys work beautifully, and the display is excelent, except that part of the middle segment on the rightmost digit doesn't light.
