Not sure whatever became of my raising an issue of a MC6821 masquerading as a MC6840 in the libraries, but I found another badly drawn / defined symbol.
Missing the alternate output (pin 1), half the input pins are flagged as outputs???, and one even as a power input?!
I already rolled my own and moved on (other than the Device library, most of the schematics I have now use symbols from my personal ‘master library’ instead. Easier that way).
I would say that the kicad library is a gift to the community. It lets users quickly get started building up a personal library – copy the parts you need, organize as you see fit, and tweak whatever is needed to suit your needs. This comprehensive work has an incredible amount of valuable content.
Also, it seems many users don’t build personal libraries and are well-served by the kicad collection.
Yeah, there will be some glitches here and there, but I imagine repairs are not a particularly high priority for the limited hours devs have. Speaking of which, a great big thank you to the kicad library maintainers is in order!
I remember eagerly reading through mc6800 docs around the same time I learned z80 assembly. And I have designed quite a few things with good-ol metal-gate 4000 cmos. But that was decades ago – what sort of retro gizmo are you designing @Meterman2026 ?
I believe I did raise an issue, but it was dismissed as low-priority (probably no time for ‘old’ parts given the dizzying number of atomic-level parts currently in the library).
As for what the project was I needed the 4078 for, I was documenting a circuit board as part of a small data preservation project - see the clip:
I believe I made my way over to Gitlab and raised an issue over there. I seem to remember that it was closed without comment a short while later, so I didn’t bother following up any further.
At GitLab after signing in I can in search box select Author then is (=) and then select myself and after clicking magnifying glass icon I have only my issues.
