Once I started technological archaeology excursion, I became interested in finding out everything about the work I had  accomplished at Heads Up Technologies.  So questions like, "How much code had I written?" became interesting to me.  But these questions were difficult to answer.

From about 1987 through 2000, I consolidated a lot of C-language source-code, Intel-8051 assembly-language source-code, and some software documentation into a "reusable library".  It requires more effort than I'm willing to put into it to determine how much of this "reusable" material is specific to any given product, and how much is shared between products.  Consequently, I'll just present the total quantities of stuff found in the reusable library, and you can suppose that divides among individual products however you like:

• C-language source code:  172.7K lines.
• Intel-8051 assembly-language source code:  83.2K lines.
• Documentation:  1000+ pages not traceable to specific products.  (I counted to 925 and then got tired.)  Documentation easily traceable to a specific product is not included in this total.

It's not a lot of code, but it's not insignificant either.
