I don't 'collect' chips so much as I accumulate them. I recently
got a whole scad more being thrown away at work. (Anybody need a
Triac? I now have 900 of them new in the tubes.) I do have some
chips that I collect individually, and there's room for such a
hobby to evolve. Early datecode analog and TTL parts have a lot
of interest to me. I've always spent a lot of time looking up
and speccing out any IC Part Number I've not encountered before.
But I want to USE them in new projects. The most recent project
I can look back on was an all-TTL stepper motor controller that I
built some time ago.
One of the important parts of any tool like this is a good parts
library. I now have gschem up and running and it has LOTS of the
things that are important. My trial run with it is going to be
the schematic for the 8088-based SBC I posted about a few weeks
ago. I have the printed schematic from the manual for that, but
it's very coarse and I want an editable/revisable version anyway.

above 110 F in the summer.
I post from time to time about giveaways. I am talking about
things like Apple CDROM drives, etc.
I am at the point where it's time to post
giveaways and
real-cheap-sale items on eBay just to get rid of some of the
excess, which isn't necessarily museum-grade stuff, but then... I
Will you give us a chance before ebay? :-)
I'm a
hardware person, and what I really want to focus more time
on is using some of the 'classic' silicon I have accumulated.
Z80 sbcs (real Z80, not the new clones and ASIC things) and the
Intel 8088 project that I've half completed.
Pray tell, what is the "Intel 8088 project"? All those wonderful
8255, 6821 and Z80 peripheral chips, all the SRAM parts I have,
etc.
I only recently heard about people specializing in collecting
individual chips rather than whole systems. It makes perfect sense
from a collecting perspective now that I've heard of it, but I'd never
considered the idea myself. Do you purposefully look for specific
chips? Are you satisfied in removing them from shipping systems or do
you try to find "virgin" chips in their shipping tubes?
I'm now in
the process of dipping my feet in the GnuEDA
package, [...]
I recall reading in EE times about another freely available tool chain
that was quite useful for small projects. I can dig up a reference if
you'd like. I don't recall it being specifically named as "gnu"
anything, so I think its a different toolchain from what you're
describing.
