As many of you are familiar with, getting Christmas goodies related to our hobby is very difficult as our loved ones don't understand the hobby and let's face face it we do have our niches. So one of mine has been Single Board Computers I've worked with or intended to work with (can't much more niche than that, can I?). I just finished my Grant Searle 6809 Board and having fun playing with that. 
Somewhere around here I have a wire wrapped 8052AH-BASIC board. Several 6809 boards I helped develop in the 80's which I need to reverse engineer because I can't recall the GAL equations we used. Also I think the boards may not be quite right (bad traces). I still have a bunch of Motorola 68xx boards, might have a Z8 BASIC chip, and a recent discovery an INS8073 BASIC chip (SC/MP family?). I must have purchased that chip back in the late 80s'. So I decided I'd build that board before I forget about it again. I've gathered up a bunch of information from the 'net and found a book 'How to Design, Build & Program Your Own Working Computer System' by Robert P. Haviland. I'm not sure how much I'll stick to the designs in the book but I'm happy with the purchase.
So far, from what I've read, this is one of those odd microcontroller chips (not a straight 8 bit processor with 64K of address range). Intel's 80xx family of microcontrollers are like that.
