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 (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.

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...

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.

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... - Great Microprocessors of the Past and Present
