Did you happen to order the external selector from @Frank_fjs? That way you just get a longer USB-C cable?
I did order one of the new LCD selector but I haven't heard from Frank in a long time. Anyone talk to him lately?

I'd still like to get one of these made if someone here can do it.

:)

What's up! Loving my Sega 16B Multi!

Can someone make me a 1 foot extension for my selector? I need to move it as the way I'm mounting the boardset it sticks up too far. An extension will allow me to move it to another place.

I need it to be 1 foot long and have a male end on one end and a female end on the other. Not sure what the 10 pin connector is called. See pic below.

If you can make me one, send me a total shipped and your paypal.

Thanks!

Hi @Brentradio , according to @Frank_fjs this cable is "A 10 pin (5x2) way IDC cable."

this was based on a similar question in the selector thread:

something like this should work:

Did my m72 and 16b multi this weekend. m72 perfect first attempt. Been dealing with graphical glitches on the 16b, all eproms verified blank, programmed, verified. Donor board is a shinobi with a regular z80b and 6800 and no security chip present, board ran flawless for hours prior to installation. Pulled all eproms and verified no bent pins with correct chip orientation, reloaded all 15 rom images into my wellon vp598 one at a time and re-verified the labeled chip to ensure i didn't confuse file number and chip number, all chips re-verified. All sounds and games function perfect, games like fantasy zone, tetris, excite league are missing half the animated pixels. Is there an eprom or range of eproms i could focus on replacing before i shotgun the whole lot? Do i need to consider the b boards jumper settings?
Cheers.

Please elaborate. I don't understand 'missing half the animated pixels'.
Backgrounds are flawless, controls flawless, sounds flawless. Graphics glitch in and out. I have an entire another batch of fresh EPROMs, I’ll just get busy and try those out. Easy.

Something wrong with the sprite data. Looks like a stuck or floating address line too me.

copy. my background is automotive, code is fully over my head. i did watch each chip and all the 322's verified in the same time spec @ 11secs. i will say the legs on the chips have some visible oxidation, i would be more suspect but my wellon would have identified a pin not reading.

The ZIF (zero insertion force) socket on your wellon, grip the chip legs differently than the PLCC (plastic leaded chip carrier) sockets on the multi. So passing on the wellon doesn't guarantee good contact on the multi. Removing and reinserting the EPROMs from the PLCC sockets is a good way to "clean" the chip legs.
