Texas Instruments TMS1000NLL Die Shots
June and July have been very busy for us, but not busy at the acid bench or microscope. Now we're back in the lab and getting down to business, knocking a few chips off the top of the amazing pile of historic devices we've received from donors lately. Here's a very early microcontroller from TI.

6800 Visual Simulation
Thanks to Jorge Cwik who's joined our preservation and modeling effort, we've got a complete set of polygons for our Motorola 68A00P, made in 1986. Jorge worked in a standard vector drawing app, Corel Draw, and has written scripts to help with the work. He's provided data in SVG as well as extracted a netlist for the chip. After converting to our visual sim format, many folks on the Visual6502 team helped debug the netlist and bring the chip up in simulation. Our wiki entry for the chip links to the simulation and other 6800 material. Enjoy!

Even better - Jorge is eager to get started on other chips, and in fact, he started modeling a famous Atari chip before discovering our project. Way to go, Jorge!

Motorola 6800 delayered
We've posted a step-by-step description about what we do to look at all of a chip's parts: Motorola_6800_die_shots.html
This features five high resolution die shots of a Motorola 6800 chip as we remove layers of material one by one. Each of the die shots is aligned, so by loading them into a paint program on different layers, you can flip between them to get an idea for what's what.
We have a similar breakdown for a custom Apple Lisa chip, a 341-0064A, which is actually a National Semiconductor COP421 customized for Apple. A gate-level model of this rare chip will be a great asset for computer history.
