Ah, but it DOES have VRAM - just not a VRAM simm ;) The 41264 chips at UC6 and UC7 are probably worth looking at.

@max1zzz has even managed to make this work in a PLCC package, too :D

Wait - someone tried to install Windows?! 😂

Seriously impressive work there - also, just a little bit jealous that you get to find this sort of e-waste at all!

@Mac84 can you repost this as a resource? It's excellent!

Hey Ron - i've moved this to the 3D Printing section, but left a permanent redirect in place so people in the Apple I/II/III forum can still see it :)

Hi Jess - welcome to the madhouse - luckily for you, we cover literally every system going plus, as it would appear - plumbing. Just dive right in - there's also an active discord server with dedicated channels for each subforum.

@Trash80toG4 - in case you hadn't seen, the RTC has finally been reverse engineered and implemented in an ATTiny85 (SOIC) on a carrier PCB. https://tinkerdifferent.com/threads/the-apple-rtc-has-finally-been-reverse-engineered.2260/

I wonder if you'd have more success using PAL SIMM's for this - that was quirk on the IIx's

I'll take that bombed board off you, if you still have it!

Please note - all credit goes to Phil Greenland for this: https://www.quantulum.co.uk/blog/new-timepiece-for-a-classic-mac-part-1/ https://www.quantulum.co.uk/blog/new-timepiece-for-a-classic-mac-part-2/ So for anyone with a classic mac needing the 8-pin DIP package RTC, this is the answer! I...

The ADB has, however, been successfully reverse engineered - I do have some original PLCC ADB chips which can be used with the adapter PCB, but it might be better to get a PIC16F87 programmed with the reverse engineered code and soldered to the adapter instead.

For the CPU socket - can you provide us with pictures?

Ooooh - looking at those, i wonder if there's an escape room game for classic mac...

Aaah, gotcha - if it's an iMac, then no need to worry about my question, it's only pertinent if it was a B&W G3 tower. As long as the drive is partitioned into multiple smaller volumes, you should be okay - it should recognise the drive as-is, but make the partitions 127GB or less each as...

Hi Bryan - welcome to TD! What is your current G3? Is it a B&W model, or a beige? I'm guessing a B&W - if so - do you know what revision of ATA controller you have?

@jgrip decapped and imaged it, here: https://chips.c128.se/brainstorm/

Where are you based? I can rustle up a cheap G4 :)
