CORRECTIONS
a 1901-0535 is a schottky RF detector diode - see 10811 parts list.
1826-0059 is not an LM208 which has a part no 1826-0072.

01-40 = 1901-0040 = 1N4148

Further correction
1826-0072 is actually a uA208 from Fairchild.
so 1826-0059 could still be an LM208 -different vendor.

Since several of you have mentioned the 10811, or how
the 10544 differs from the 10811, you will find the original
HP Journal article about the 10811 very informative. See
pages 20 to 29.
