looks like a 24X, but the RAMDAC seems a 80MHz part - I cant read the ROM which is where most times the model is stated... ETA Squinting real hard it loks like it is a 24x -however the 80MHz RAMDAC baffles me, should be a 110MHz? Maybe I'm mistaken?

Beat to the punch! Yes that’s the one.

I hated the LC power supplies, and decided to replace the innards of those things with MeanWell psu. lower ripple, cleaner and more power overall. No brainer for me…. Less time lost and 100% success rate. And it looks identical from outside anyway

@trag, I'd like to purchase 4-6 of these KM4132G512Q-10 chips you have... Ive got two 6500 boards that I'd love to test your theory out. I have a heating plate and hot air reworking station, so Im confident I can do the swap.

I know it's an older thread, but original schematics for the 6500 are available. And I'm actually very interested in this topic

it is worth noting that Daan’s Takky has a DOS card inside… but what is crazy is that it WORKS

In Italy it’s expected to survive at least through 2035….

while I sure agree on the analog TV, sorry to say but regarding FM what are you talking about? FM is still used all across EU and I can still use a 1970 Toshiba receiver for hifi audio today

Hi and thank you! Unfortunately, it cannot work with an existing CRT tube as the main reason I started off in this five year long adventure was the fact that if the flyback transformer breaks in the analog board, you're done for. There is no way that a new replacement ever will become available...

Well yes! it will take some time though, as i am not alone in this adventure. But most definitely this is a work of love for all the Macintosh enthusiasts and fans out there.

This is a nice tech writeup that daanvdl did on our project! Technical Appendix – LCD Display Connection for Macintosh Color Classic and Takky Video Board Introduction This appendix outlines the technical specifications and connection requirements for using an LCD display with the newly...

After four years, the Color Classic LCD Project con be finally! be considered complete. I initially posted about this project here: LCD Color Classic, where you can also read about the philosophy and why I had started the project in the first place. TLDR – I had a problem in one of my CC due to...

Yes. I partnered with the great DaanVDL. Great things are coming….

So first off, I did try to search for this particular problem and I could not find, it so if i missed it i apologize! I've also looked at all jmacz threads but they are way over my paygrade. I have an identical card to the one I posted a pic of. A Supermac Spectrum PDQ with firmware 1.27 - just...

Can you share the source of the MC88916-80?

I have to try OSHpark with clear mask!

No, I mean the "neutral/clear" color of the PCB. Also like something max1zzz posted:

So I started looking at older PCB from the 70s, all the way to early 90s... and there are PCB materials that look fantastic. I do not understand why no one offer these materials, and I do not mean the traces such as gold (yes pure gold and not enig) like some of the early HP lab stuff, but the...

@clockchip, interesting 512K VRAM you've got there, do you have some info?
