TFMSX Rev2 specifications

Hi.
I've recently got one TFMSX rev2 board on my hands for testing, which is made by Chucky. I've been chatting with emails with him as I can't fire it up.
I've tried to find an information how it needs to be configured, like
- what kind of power supply is required? (5VDC, negative center is the only information I have, my power supply gives 5VDC/2A and polarity is changeable)
- DIP switch settings? (S1, S2)
- monitor port is informed to comply with the Amstrad CPC+ specification, and this board it's 8-pin DIN 262 degrees
VDP jumpers are marked clearly.

The power supply is 5V +ve centre. The Dip swtiches pick rom bank of 1 to 4.
Code: Select all

# wget http://www.msxarchive.nl/pub/msx/emulator/openMSX/systemroms.zip
# unzip systemroms.zip
rm -f *.rom* bank* default.rom

cat MSX2.rom MSX2EXT.rom DISK.rom > bank0
cat MSX2BR.rom MSX2BREXT.rom DISK.rom > bank1
cat MSX2P.rom MSX2PEXT.rom DISK.rom > bank2
cat MSX2SP.rom MSX2SPEXT.rom DISK.rom > bank3
cat bank0 bank1 bank2 bank3 > default.rom
This is how the (default) roms are created.
The RGB cable is the CPC+. Chosen because it was the cheapest i could find. Here is the URL.

Oujeah - Thanks for the clarify! :) I switched the power supplys polarity and the board immediately fired up.
I had only 8 pin din 270 degrees connector, which is not very co-operative in here, so perhaps I need to find either the correct video cable or din connector.

The decision for this cable was entirely because it was the cheapest one i could find on any website coupled with the fact the MSX didnt have a standard video output connector.

I still need to return to this - Where I can find reliable information about the video connector pinout and what format it delivers (RGB/component)?
I've tried this one,
https://www.cpcmania.com/Docs/Scart/Scart.htm (CPC464+/6128+) without external power connection, as I _guess_ that power is delivered through the video connector (just guessing, but pin 3?).
Neither my Finlux-tv (which I use with Atari (scart/vga) or Specrtavideo's (side AV)) or OSSC does not recognise the signal from TFMSX.

The pinout is the CPC 6126+ without the power. I chose it because it was the cheapest cable in this category.
