Yay upgraded memory to 20MB.. niiiice. Thanks @LaPorta. ☺

This is awesome ☺

Given up trying to find a nice compact mac..

@joshc Well originally adb.. I swapped them both around which just moved the fault.. which is how I found it.

Sounds exactly like the fault I had.. I'd look around the adb asic.

Cheers @Phipli ☺

Ahh that links dead 😂 darn

Ooo thanks for that.. that'll help ☺

I have one of these.. are they any good? I'm guessing it needs software as I cant get anything to be seen on it. I cant even remember where I got it 😂

The mac bench

So far so good. 👍

Ive managed to find my salvaged parts pot and yay there was another asic in there.. after bending all the pins back as well I could.. swapped it and yay tis working now.. thanks all for your help and motivation. Gonna give ita darn good testing today.. fingers crossed. ☺

So cute..

@mdeverhart Between pin 22 and 28(5v) its 508 ohms And pin 22 and gnd is 521 ohms. Pin 27 goes from under the sram ic through a via and then a track on the other side to another via and up under the asic. Ive checked the other asic/sram combo as its the same setup. and pin 27 to gnd is 456...

Will check ☺

Yeah did that.. it's a straight connection.. only other thing I can think of doing is lifting pin 71 of the asic and seeing what the resistance is then between the pin and gnd and the now unoccupied trace n gnd just to confirm.. but i recon the asic is at fault here.

Okeydokey cheers @mdeverhart I took these readings.. Betweeen pin 27 and 28(5v) 469ohms Between pin 27 and gnd.. 452ohms Between pin 28(5v) and gnd.. 15 ohms I was thinking along the same lines but wouldnt know what value resistor to add. Ive checked around there and theres no pull up...

Ahh I see whats happening here... pin 27 on the sram is low.. the machine death chimes.. if i dab some iso between pin 27 and 28 (5v) it seems to pull it up and it goes up to around 3.5v and then the machine works just fine.. Ive fitted a new sram ic and its made no difference.

One button is all ya need

That's gorgeous.. I love my 8100/110 but this is on another level of cool 😎
