Documenting and upgrading the RiscPC

Over the last couple of years, I've been collecting the parts too upgrade my RiscPC with a second slice and 4 slot backplane. The parts aren't hard to get hold of but they can be hard to find at reasonable prices.

The RiscPC's modular screwless design makes the upgrade process simple and easy so I took the opportunity to document and of its other features too such as its 16-bit audio upgrade and a conversion from a rechargeable battery to a coin cell.

For more information about the RiscPC and it's upgrades, please take a look at the dedicated RiscPC pages.

More VELA peripherals found

Around six weeks ago, I acquired a four channel temperature sensor that connects to the VELA using the digital port of the VELA rather than the traditional analogue connectors.

VELA temperature sensor module

The sensor unit provides a way to connect four thermistors to the VELA so that four discrete temperatures can be measured at different locations in an experiment. For more information about this temperature module please take a look at the VELA temperature sensors page
I've also managed to acquire a set of original VELA pulse triggered light gates which can be used to measure speed and acceleration when used in experiments using a "car" with a card which interrupts the light beam created by the light gate.

More information on the light gates can be found on the VELA light gates page.
