I've heard from a fellow, Vince S., who has created a PCB layout for the PDP-8/e 32K
RAM design presented in my article on
Tronola.com. He's considering a Kickstarter
launch to offer a $95 kit of parts and PCB but is wondering if there is sufficient
interest. If so, please let it be known.
Features include:
- Battery backup with estimated 10-year data retention.
- Inhibit on power fail to prevent memory corruption.
- Most of the full size Omnibus board offers a prototyping layout.
- Cooperation with any mix of core memory boards. Switches disable 4K fields.
- Compatibility with Omnibus specs.
- All through-hole parts, for easy assembly.
I'm not associated with the project, other than having published the article and
encouraging his efforts. Vince has published lots of PDP-8-related and other layouts on
his website and will make this one available as well:
