    Another die shot of Am2901 bit-slice processor. In this one, I dissolved the metal layers so you can see the silicon transistors. Compare with original photo. Register file in center, 4-bit ALU in lower right. Empty regions used for buses. Bipolar transistors look like rectangles

    Die photo of Am2901 chip with metal layer removed. Die is bluish, with small transistors.
    Detail of die photo showing many transistors. They appear as a complex pattern of rectangles.
    Die photo of Am2901 chip. The bond wires are connected to pads around the chip.
    Detail of die photo with metal removed, showing transistors. They are overlapping rectangles.

    New blog post - Notes on DIY photoresist synthesis from accessible materials. Near the end of the post there are also helpful hints on chemical sourcing for amateur scientists, especially if you have access to a commercial shipping address

    Die photo of MC68HC05SC21, and closeup of where opcode bits are swapped (and inverted) - versus comparison image showing same location on MC68HC05P1 which does not have swapped bits. Closeups of ‘SC21 have been flipped and rotated to match orientation of the 68HC05P1 photo.

    Die photo of MC68HC05SC21 taken with microscope. The area where bit swapping and inversion of opcode bits can be seen is circled in red at the lower right corner of the image.
    Closeup photo of MC68HC05P1 showing opcode bits connected to bus in order (no swapping).
    Closeup photo of MC68HC05SC21 showing opcode bits read from bus with some bits inverted and the order is swapped. (Photo has been flipped and rotated to match orientation of MC68HC05P1 image.)
    Annotation added in red, indicating location where swapped and inverted opcode bits can be seen on a closeup microscope photo of MC68HC05SC21.

    RIP Randy Suess, one of the inventors of the BBS. If it weren't for him, a lot of us would not be the people we are today. He gave me a place to find my people.

    Happy Mac / Sad Mac scarves back in stock: vintage Mac ROM from a Power Mac 5200 knit into a scarf. The ROM has hardcoded images in it. Comes with code by to make an image out of a ROM with a command line script for the exact wrap length of the scarf.

    Torch decap round 2: better, but still lots of thermal stress. Too risky for me, but good acid alternative with more practice

    Any other Canadians here have a real nostalgia for that period in the early 2000s when everyone was stealing DirecTV?

    Back grind PCB to remove underfilled IC. For decap, but more careful removal could probably be reballed
