Very impressive solution! Having the CPLD assert /DTACK directly is both elegant and highly effective, eliminating the slowdown entirely without requiring an INIT. Excellent work!

@jack 68k 68k Jack, how are things progressing with Reconnaissance? It’s great to see the amount of traction and positive feedback the project is getting. I’m curious how things are going from your perspective and what the next steps are for the project.

I recreated this power supply board a while ago, in case anyone needs a replacement PCB for a CR-76E/CR-76U supply. The project files are available here: https://github.com/daanvdl/macintosh-portable-cr76e-powerboard It may be useful when the original PCB is too badly damaged by capacitor...

Great!

Is this the correct Tigard programmer? https://www.mouser.com/ProductDetail/Securing-Hardware/TIGARD-V1

@campbellashe I’m not very familiar with CPLD programming, but I’d like to give it a try. Which JTAG programmer would be suitable for programming the ATF1502ASL?

I recently recapped a Delta Electronics LR57908C power supply. This PSU is commonly found in the Macintosh Quadra 700 and is labeled as: Model: SMP-120EB Apple Part Number: 614-0009 For anyone planning to do the same, here’s a complete parts list with modern replacements. 🌀 Fan Original: NMB...

Simply amazing!

Ah, I hadn’t seen this thread earlier, but it aligns perfectly with one of my recent projects. I recreated the original Sony CR-76E power board used in the 7.5 V / 1.5 A M5136 adapters for the Macintosh Portable, intended as a replacement for boards that are beyond repair. I’ve published the...

In addition, regarding the LCD (referring to point 8 in the previous post reply): Currently, we still have a few K08AS left. We believe this is a truly exceptional display for this kit. While we are naturally very enthusiastic about the final result, it's important that there's sufficient demand...

Just diving in — I actually designed the analog video section and board for this particular LCD-CC kit with the curved glass frame. Yes, it’s running 640×480 on an 800×600 panel. It works surprisingly well, though there’s a bit of visible upscaling here and there. I’m still quite happy that I...

Keep us in touch please! Really like to see the photos;)

This is such an awesome project! I especially love how it's completely independent of original/custom parts — that's seriously impressive. The timing couldn’t be better either, with all the great replacements now available like the RTC clone, sound chip replacement, IWM bypass, etc. I'm already...

I have recently been searching intensively for this variable inductor. The range is from 0-35 approximately. After a long search I found a batch (NOS) that met the specifications. If you still need a replacement: https://airtalk.shop/product/l2-adjustable-inductor/
