My SBC list - Quest Elf, COSMAC VIP, Z-80 "starter kit", Motorola 4MHz 68000
evaluation board, SYM-1, AIM-65, BASIC Stamp I (14-pin SIP module).
My SBC shopping list - KIM-1 (with working keyboard, natch' :-), Elf-II,
IM6100-based board (Intercept?), Motorola 68330 evaluation board.
I have the article from 1978 where the Elf-II is written up
(
http://penguincentral.com/retrocompuing/ElfII/). I've just re-done the
text at the end and am preparing to scan in the missing figures. Some of
that is the actual artwork for the Elf-II PCB. I know I can buy iron-on
transfer paper, but I've never made a double-sided PCB at home, only
single-sided (and then, only with rub-on transfers). Has anyone out there
ever made double-sided boards at home? I'd feel better if I had a layout
package and made my own files so that they'd be nice and square, as opposed
to a scan from a 23-year-old magazine, digitized and laser printed, but I
haven't found a layout package yet that I could manage to start from schematic
and end up with something printable. Suggestions there would be nice, too.
