I don't think I'll tell Travis Goodspeed what I'm doing to his wonderful tool...
(I'm adding template matching to MaskRomTool and it's doing a *spectacular* job at detecting flipped bits based on their diffusion shape)

The front base part of an Olympus BH2 metallurgical microscope, shown mounted on an aluminium base plate. The Y axis CNC motor and coupler are visible in black, front centre of the base plate. Behind it is a set of three RGB LEDs firing into a beam combiner cube (X-cube) pillaged from a scrapped 3LCD projector. A Makerbase MKS GEN1.4 3D printer control board is visible at the edge of the aluminium plate, with a halogen lamp plugged into it. A load of cables run from there to the LED driver boards.
Lunchtime project complete - this is the MKS GEN 1.4 (RAMPS 1.4) board which runs my CNC microscope. It now has RGB LED and halogen lamp brightness controls. #pyuscope #icre #icreverseEngineering
Which pad is which? #BSBACM edition.
First we trace out the power pads...
There are 52 bond pads and 48 pins, so 4 of those pads need to double up...
I would love to know why the Acorn/#ARM Albion IOC has an all-seeing-eye symbol on the die. #ICReverseEngineering #ICRE
Any #ICRE #ICReverseEngineering folks recognise these logos or the text? They're on a bunch of random silicon dice and packaged chips I was given.

Chips a la Phil #icre #ICReverseEngineering
I've been taking the tops off silicon chips again ...!
This time it's a weird chip called the M4613D/A which turned up in a Blaupunkt data terminal. A computer museum in Spain dumped the ROMs, and Pernod is working on a MAME emulation […]
