Re: Cosmac Elf and Eagle
- Hallo allemaal,
Kind regards, Ruud Baltissen
- most of the parts on the boards should be standard dip ics and passive components. If you search in the message archives of this site you'll find some threads like this http://dir.groups.yahoo.com/group/cosmacelf/message/3913 that talk about eagle and certainly point to schematics.You could also post pictures of the loose pcb system. someone may recognize the style and it would be interesting in its own right.

Subject: [cosmacelf] Cosmac Elf and EagleHallo allemaal, (hello everybody)
My name is Ruud Baltissen, I'm Dutch and new to this group.
Two weeks ago I received two 1802 systems: one built using small
PCBs connected to each other with a lot of wires, the other one
using an ELF II as base plus some extras, for example a keyboard.
I haven't any idea if they work. To be honest, I have my doubts
because I saw some loose wires here and there. For that reason I
want to make a schematic of both systems first and compare them with
original schematics. That could simplify identifying the loose
For creating schematics I use Eagle. The advantage of this software,
there is a freeware version available:
As I have no needs for making PCBs, It's ideal for me. Another
advantage for me: a lot of my Commodore friends use it as well.
My question: is anybody of you using this software as well and does
he/she have schematics and a library with parts available for my
use? It would save some labour :)
Thank you very much in advance!
My future plans with the systems:
- I want to restore the 'loose PCBs' system to its original state as
a hommage to the original builder. (I and the previous owner have no
idea who that was)
- I want to restore the ELF II to its own original state and then
use it for further expansion like adding an harddisk or CF. Quite
easy when using the expansion slots IMHO.
With the systems I also received a lot of magazines that I'm
scanning now. They will be made public as soon as I'm finished with
that. Unfortunately there will be a small problem for the most of
you: they are all in Dutch.
Kind regards, Ruud Baltissen

Sorry, I don't use Eagle software. I'm only using Autocad for now. Not the best software for schematics, but it gives me the control I like.
