Laser-cut cardboard stencil jig. Hmm… hmm. So close.

NEVER MIND THAT. Cardboard bits instead!!

It went… okaaaaay. I had to redo most of them a bunch of times. The cardboard was a lot thicker than the PCB, so way too much paste got through! I’m also using scavenged vintage capacitors because I still haven’t ordered any new ones 🤣

Getting there… I hope this works #vintageComputing

This didn’t melt the solder at ALL. I had to manually set the oven to 240°C to get it to work. Package says 180°C but… Aliexpress. Also, maybe the oven needs recalibrating! (Vevor *and* hacked firmware 🤣)

Honestly shocked… all four simms worked, first go! 64MB!!

I’m not sure the most-thorough memory test was designed with 64MB in mind. This has been running for about 13 hours 🤣

@j twisty boi capacitors
Show threadJames against the machineSep 29, 2023
@jpm yeah they’re way too big 🤣 most worked ok!!
Show threadI love this, so ISep 29, 2023
@j I usually use spare circuit boards from finished projects or superseded designs. I did try 3D printing one which worked pretty well too

@jpm I designed it to print but then was in a lAsEr MoOd

I usually use old boards too but these are a weird thickness and I have no others ¯\_(ツ)_/¯

@j ah that’s fair, not the normal 1.6mm?
Show threadJames against the machineSep 29, 2023
@jpm 1.2mm to fit the ol’ sockets. They *should* be Thicker, I think, but no one makes imperial boards any more ¯\_(ツ)_/¯

@j aha gotcha
