I finally got around to programming the CPLD for my Fusion Converter build. I made a harness using the Mill-Max connector I mentioned above, mated to the Tigard programmer JTAG pins. I then realised I was unlikely to be able to hold the connector whilst also typing OpenOCD commands so I figured...

I've used them to date mainly when printing MVS and PGM cartridge cases. I got these tips from Amazon that fit my Hakko FX888D: https://www.amazon.co.uk/dp/B08B17VQLD I just press the inserts in by eye. Seem to have worked fine so far. Edit: I don't think the particular iron matters so much...

I can program the modules for anyone in the UK (or nearby). I've got all of the adapters for all of the multis, curse this hobby! ;)

Ordered. Be still my quivering credit card.

That's pin 9 with respect to the ZIF socket on your programmer. So it's pin 1 on your chip. On a regular 27C040 that's the VPP pin which requires around 12V for programming the EPROM. A mask rom wouldn't have any need for that so that pin either has some other function or it's NC. Either way...

I received an email today from PixelHeart stating GladMort should be shipping on Monday 26th for all versions apart from AES JPN which is delayed due to a printing quality issue. Also received my Project Neon MVS batch #3 cart a couple of days ago.

You should be able to confirm by beeping the JAMMA edge from the coin switch finger to one of the missing filters on its outer pad. I'm fairly sure you can just bridge the two outer pads in a pinch as they're just EMI filters and the middle pad goes to ground. They then probably join up to the...

That Tigard board actually looks quite useful, and I can get one from Mouser along with everything else. There's no such thing as too many FTDI widgets!

This is what I found: https://www.mouser.co.uk/ProductDetail/575-8552200610003101 I haven't ordered one yet, but it looked like it should work if the pads are spaced correctly. This is what I was expecting to have to do; inject 5V into the board so the on-board regulator generates the 1.8V and...

I was curious how you're supplying power; I can't tell from the photo but it looks like you're using the same FTDI trinket that is used for programming the Neo Geo Diag PCBs which only supplies 3.3V or 5V, (at least the one I have anyway), and the CPLD is a 1.8V part. I found a Mill-Max part...

Project Neon MVS Batch #3 just dropped if anyone was waiting. Also +1 for Xeno Crisis, I think it's fantastic, I even have it on GBA for alien shootings on the go.

You can replace bad CRE401's with https://github.com/mourix/CRE401 if needed, it's slightly more than just a resistor array.

Neo Geo Memory Card now sold. Time Sleuths still available, I can probably print a case in a different colour if the orange is too off-putting.

My MV1B has one of the NEO-BUF bypass "patches" on the slot PCB, (the one on the main PCB is still present). According to https://wiki.neogeodev.org/index.php?title=NEO-BUF bypassing one/both of these, (it doesn't state which and sort of implies there's only one, when there's actually two), can...

That looks like a potentially lifted pad
