The next board from the cemetery is the VT5329E, a Socket 370 development board which was probably used to validate the switch between Trident to S3 Integrated graphics in early 2000s.

The VT5910A development board is one of the most interesting boards from the cemetery.

At first sight, the VT5426D board is very similar to the previously analyzed VT5292A.

Let’s continue the series with another one of the least damaged boards: the VT5292A, built around the Apollo PLE133 chipset, with a VT8601A Northbridge and a VIA VT82C686B Southbridge.

Some years ago, one of the last remaining VIA R&D facilities closed its doors, and I was lucky enough to save a bunch of motherboards from the salvage bin.

I’ve just finished restoring one of the few computers Intel produced in the early 1990s, and I’d like to share a few pictures of this wonderful platform.

A few months ago, I came across what looked like a real gem on eBay US: a studio copy of Intel’s iconic “Bong” sound.

During the beta-testing phase of the Universal Chip Analyzer (UCA), some testers noticed that certain CPUs failed on the UCA while appearing to work on more basic testing devices.

Designing a stable, adjustable and fail-safe power supply for the Universal Chip Analyzer has been one of the most challenging aspects of this project and I was quite reluctant to touch that part of the schematics.

The Universal Chip Analyzer (UCA) beta testing is entering its final phase!
