A complete kit to give your RC2014 the advanced graphic capabilities of the mid to late 80s. It's based on the V9958 Video Display Processor (VDP) which powered the MSX2+ line of 8 bit Z80 computers.
This V9958 chip, was produced by Yamaha in the late 80s and was an update to the their V9938 chip, which was itself, a successor to TI's TMS9918. The V9938/V9958 addressed many of the shortcomings of the original TMS9918.
This is the first board produced within the "Yellow MSX Series".
These are a series of boards that I am developing to achieve MSX compatibility for RC2014 systems.
The idea is that you can build each board one at a time, test it and play with it under RomWBW - and then once you have the set - load up some MSX/MSX2+ games!
The V9958 board is the first in that series.
More details can be found on my hackaday project
The full kits includes everything you need (PCB, passive components, crystals, sockets, connectors and ICs including V9958 and 4x41464C RAM chips)
(The components for both the PAL and NTSC versions are included).
Please note that due to the finer pitch pins of the V9958, the soldering of this board requires a little more finesse than the typical RC2014 through-hole based boards. If you have built a few boards already, then you should be fine. It's recommended that a finer pitch soldering tip be used as it can be easy to accidently bridge some of the pins.
Extra care needed when inserting the V9958 into its socket - there are lots of pins, take your time to avoid bending pins.
You need to identify if you plan to build a PAL or NTSC version and select the correct resistor and capacitors for R13 and C14.
Please note that this is a kit, produced by a non-professional (me) for hackers, DIYers' and retro lovers, to tinker with. I will do my best to answer any support questions you may have.
The V9958, CXA1645P and 41464C chips are obsolete and out of manufacture. 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.
I have conducted the following tests for this board:
