Description
An in-circuit tested V9958 VDP.
The V9958 by Yamaha is the VDP that can be optionally included when purchasing the Stegosaur MSX V9958 RGB for RC2014/RCBus kit.
Its listed here if you require just the VDP.
This V9958 chip, was produced by Yamaha in the late 80s and was an update to the the V9938 chip, which was itself, a successor to TI’s TMS9918. The V9938/V9958 addressed many of the shortcomings of the original TMS9918.
The V9958 is an obsolete and out of manufacture product. They may be old-new-stock or pre-used, and as such there is a risk they may not function correctly. Therefore, I fully test each chip, in-circuit, prior to packaging, so you can have good confidence that the chips you receive will perform as required.
Items are packaged in anti-static foam within an anti-static bag. Bubbled wrapped and boxed for delivery.
