I think I'm almost ready to send the prototype of the RAMpager for the #KIM1 to the fab. Probably going to do that next week, including Mouser order for components. Currently a bit in a pinch with vet expenses.

I changed the circuit that handles the /CE signal for the SRAMs to try avoid parasitic currents from the battery to the GAL22V10. Tried to cut it off using mosfets.

I also added the option of using either a 1N5917 to power the SRAMs if you wish to stay THT or a PMEG2010ER (SMD) that has lower leakage current.

We'll see if I made a mess doing this. I probably have. But you fail and learn I guess...

Sent the Rev.0 of the #KIM1 RAMpager to #PCBway for sponsorship approval.
If they greenlight it, I'll also prepare a mouser cart for the build

Looks like it got approved! Time to start filling in the mouser cart!

Filled in. will wait until the evening to see if something else pops up in my mind.

Should be a small order, barely enough to get to the free shipping quota, as I already have most of the components.

I'll still forget something essential though.

Great. #PCBway shipped the prototype for the RAMpager and Mouser shipped the package with the components for the build.

With some luck might be able to get to it next week.

I absolutely don't need one, but the name is compulsion enough to order one ...
