I haven’t played a DK in a year, but i just accidentally raised this hard drive from the dead.
Loving the FUCK out of my new picture frame. (don’t worry that SE wasn’t sacrificed to make it, I had the shell from making my OG computer work)

Macintosh Plus with Brainstorm accelerator installed, showing the replacement Toshiba TMP68HC000P-16 16MHz CPU, and the resistor taking the 16MHz clock from the motherboard.Also pictured are the the chips under the CPU card that can’t be photographed in their entirety without
Macintosh Plus with Brainstorm accelerator installed, showing the replacement Toshiba TMP68HC000P-16 16MHz CPU, and the resistor taking the 16MHz clock from the motherboard.
Also pictured are the the chips under the CPU card that can’t be photographed in their entirety without de-soldering card from the CPU and the BBA-14 TSM (Timing State Machine) replacement.
The plus doesn’t like the System 7 boot disk image I have, thus the co-processor not installed error.

(starts 11.2μs after falling edge of HSYNC, lasts about 33μs, first data line is 1.26ms after falling edge of VSYNC)
(Paired with ground connector #2) - Purple HSYNC
(square wave, falling edge triggered, 45μs per line)

- Yellow +12V DC
Marking this SE logic board like its a turtle.

tevruden:Anyway since I’m trying to reverse engineer the chips on the early classic macs y’all are gonna get stuff like this mac 512k schematic Also this equating the layout of the ROM to a modern EPROM chip, MX27C512:
