California ASIC is a full service supplier of gate arrays.
California ASIC specializes in FPGA to gate array conversions as well as standard gate array developments.
Regarding your article on obsolete parts, we at California ASIC specialize in manufacturing low volumes of obsolete parts. 1000 parts is normally the minimum that makes economic sense.
We retarget these chips to one of our CMOS processes and then deliver them directly to the customer.

Commodore Business Machines
This company made the Commodore 64/128, VIC20 and later the Amiga computers.
They contained especially made chips.
After Jack Tramiel left CBM after getting Atari for free from Warner Brothers (?). CBM went broke sometime later and was bought by Escom and when that went broke by the direction of the Dutch branch of Escom and after that went broke the Dutch computer builder Tulip bought it. Not a good omen for Tulip... ;-)

Semiconductor die and wafers
Semiconductor distributor and value-added processor of die and wafers for multichip modules, hybrids and other unencapsulated applications. Specialists in Known Good Die (KGD) processing.
World's largest distributor of bare die. We have contracts with 20 semiconductor manufacturers to process and distribute their wafers and die. We have saw, visual, wafer probe and 100%/burn in (Known Good Die) capability. We also do small lots (thousands) of hermetic assembly and test (when the manufacturer does not offer a particular die/package combination). We have three TAB bonders on line which we use for our patented SofTAB known good die (TAB leads are removed after test and burn in, leaving 100% tested bare die) and also for display drivers and other TAB applications.
We have shipped more KGD than anyone else besides Intel and we started shipping KGD years before they did! I'm sure some of your visitors are interested in a competent, professional bare die distributor and KGD processor.

Clear Logic was a fabless manufacturer of semiconductor integrated circuits. Clear Logic has created the innovative new Liberator design technology. With Liberator products, customers design using programmable logic (up to 200,000 gates) and then seamlessly move their manufacturing to our much lower cost factory-configured devices. Designers use the flexibility of programmable logic for quick prototyping. Then they simply use the web to upload their bitstream file to Clear Logic for a much lower cost production solution. All Clear Logic products are fully compatible with Altera functionality, pin-outs, and architectures.
