Thanks for linking, @alxlab. For anyone in North America, @Drake may have a few left from his 3D printing test; they came out in amazing quality: Left is my design from Drake's 3D printer, right is the original Apple gear. The gears from Shapeways work just fine but they are not as high...

A few of members are already familiar with truth tables and reversing PAL / GAL chips. If you're among the less familiar, these are chips with several inputs and several outputs. The output is dependent on the combination of input signals to individual pins — all of which can be customized. This...

Very nice! A small bench-top injection mold machine might be sufficient in combination with a small custom mold (could be 3D printed): I've done similar small batch production for Garmin mounts using RTV silicone molds.

I can't speak for the quality of the Thingiverse you linked to, I have never printed it. But I can guarantee this one will fit perfect — I spent 5 years working on it off and on.

@dogcow would say... Here's a link to this great article he wrote about upgrading the 128k and the history of it.

It just occurs to me, if you're using a 512k logic board then @Bolkonksij may be able to use one of the compact mac video adapters I posted about recently.

I think it's amazing that Jon made the source available. I feel like, even if there isn't an immediate reaction, this sort of material has a lot of value for years to come!

RGBtoHDMI + iPad Retina display + CRT2LCD adapter

Just a frigging Mac 128k in good condition. Is that really so much to ask for? (They're really hard to get!)

I hope this means JDW will be providing translation for an English version of Doping Mac.

Nice work, Kay! Another happy mac :)

"I am _NOT_ doing another Thanksgiving dinner. I can't take this anymore! Peace out." — your oven

I love how in the span of 3 posts it goes from opposing modifications to literal sparking cutting wheel. 😅

I'm excited, I hope there's a Kay cameo — at this point he's like a mysterious shadowy figure!

Khajiit has wares... or more specifically, I work on many projects! You can find the meowTOAST on github, which also lists the meowTWOast (meowTOAST v2). The board we discussed ended up being a bit too short in the first revision — I'm not really satisfied with the idea until JLC can provide an...

I believe a CGA monitor would accept the signal but it would also depend on the frequencies supported by the individual displays.

Good find! It definitely looks like a similar in part to Larry Pina's schematic.

Some time in 1988, a small company created a video output adapter for early compact macs with the model number 2702. There are other models, but the focus of my post is on this adapter. I can only assume they were a small company with a handful of employees because later the following year they...

You, uh... collect SRAM or something?

I don't have any insight to offer, but I have to admit I have a morbid curiosity to see photos 😇
