I'm currently doing a project with some of my friends on creating a chip ourselves. We have a small program called IDaSS (Interactive Design and Simulation System) which works at register/buffer/operator/state machine level (mostly for microcontrollers and sorts. You can find it at
www.eb.ele.tue.nl/proj/idassfly.html (beta version, still in development)
It can be output to a silicon compiler to put onto the wafer.
Please let me know if you need any info, the programmer is my teacher.

Chipset

A chipset is a set of chips working together and which are sold as a set. Usually people mean a set of chips to populate a PC mainboard.
These sets contain all the usual chips that used to be on the original AT motherboard like the two 8259's the 8255, 8253, 8244, the TTL* glue, the memory refresh and parity. More modern stuff to set the refresh rates, cycle times etc. Lately also the IDE*, floppy controller, printer port and serial ports have been integrated. I'm not sure if the RTC can also be integrated (except for the battery of course) but I guess so. The integration will never stop of course...
There were also chipsets for VGA* cards and modems etc. though. They were usually sold together with a software packet so a manufacturer/seller only needed to assemble the stuff and sell it...

John wrote in 'news:sci.electronics.repair':

Does anyone know a good site to find circuit diagrams for televisions? I need a circuit diagram for a 'Toshiba colour TV' model no. 145E7B.

Usual answer for people in the UK: Go to your local public libaray. There is an annually published book of schematics (and other service info) titled "Television Servicing". Normally in the reference dept.

I copied one for a Toshiba 175T9B just this Saturday...

There are also series for VCRs, and for Satellite receivers.

CPU

Central Processing Unit. (What's now a single chip main processor in a computer, was originally a complete PCB* full with discrete logic. The 2900 range from AMD could be used, but the big companies like IBM all used their own designs. These processors were called bit-slice because the words that were to be handled were sliced into 1 and later 4 bits per chip (registers, ALU's, busses, buffers).
Some hobbyists even built their own CPU's this way but the i4004, i4040, i8008 and i8080 generally put a stop to that for most of them...
