Thank you for your amazing work on this project and for your words of encouragement with the build - loving that you have shared your work - It is amazing to learn from and understand and a great inspiration. What you do is noticed and appreciated!

Boards arrived today. I’ve never worked with 6-layer before, the quality is magnificent, it’s like jewellery. I changed the USB header to 2mm IDC for these boards for my use case. Will start work on fabrication shortly

modelled a replacement for the plastic microswitch retainer and coin guide. STL and assembly instructions over here https://www.arcade-projects.com/threads/replacement-microswitch-mount-for-namco-exceleena-coin-mech.34444/#post-469952 Now just need that pesky factory credit board...

Assembly notes as follows 1 x Zippy microswitch "with needle". This was actually the hardest part to find for a bunch of boring reasons that I won't go into, TL;DR use this https://www.aliexpress.com/item/1005005262871807.html You'll need to bend the wire quite precisely to fit the guide 2 x...

This was one that I'd wanted to do for a while after the manual translation. The factory 100 yen coin mech is Series = Conlux N500 Model = N-560 Variant = N-563-1 The only difference between the N-560 and the N-563-1 is the black plastic microswitch retainer that also acts as a coin guide...

Have been working to level up my 3D printing game with better gear/finish/materials recently and one thing that seems to really help is heat-set inserts. A lot of the "serious" projects with 3D printed parts use them for durability, and precision. I got the idea from this LDO guide...

This is the cart that I ordered for parts - given that the whole thing needs to fit into a DIP32 package there are a lot of exceptionally tiny parts in here. https://www.digikey.co.nz/short/55wfn8h8 SMD 0201 is roughly .5mm x .3mm even placing these by hand requires a good microscope and...

Version 1.7 (the most recent) is a 6 layer board - normally these are hilariously expensive to produce but JLCPCB currently have a promo for $30 off 6-layer boards so I applied that. Unfortunately these boards are not particularly cost effective for PCB assembly - they are dual sided, and...

PicoRom is a DIP32 form-factor ROM emulator - up to 2Mbit in size and 70ns access speed Github page here https://github.com/wickerwaka/PicoROM and cool writeup here https://hackaday.com/2024/11/05/picorom-a-dip-32-8-bit-rom-emulator/ PicoRom does a bunch of cool tricks, but the coolest one...

The buyer was @saucydaddy great communication, prompt payment, and very patient with shipping from New Zealand. Thank you very much! Would trade again

I think I've still got some from JLCPCB - will check and confirm, one moment please

After many days of searching I've found some engineering drawings of the TSOP burn-in test socket

And for the CHA (CHA512Y) board we could proceed as follows Quick note on JEDEC vs Non-JEDEC All of the EPROMS On neogeo cards are non-JEDEC, with the sole exception of S1, which is JEDEC. A lot of quite capable programmers have problems writing suitable JDEC eproms for S1 (such as the 27C301)...

So for the PROG (PROGBK1) board we could proceed as follows Prog Board (PROGBK1) 1337-v1.v1 = 4MB = 32Mbit, we could split this in half into 2 x 16Mbit chunks, then write them to 27C160 which does do 8 bit addressing 1337-v2.v2 = 4MB = 32Mbit, we could split this in half into 2 x 16Mbit...

I'm constantly amazed by the brilliance and innovation in this hobby - have been following Hoffman's work in stunned admiration. Can download and hopefully support here https://h0ffman.itch.io/shinobi-neogeo This has been done before (and probably better than me) on this thread...

Can confirm that it’s easy to misalign the slots when replacing them (or building an AES from scratch). If I was doing this again I’d attach the slots to a junk cart first, then use that as a jig to align the slots for soldering. If the slots have been reworked it’s going to be very obvious...

More info filtering out on Twitter/X The Good AES mode with fun menus and etc Unibios support with cheats and etc Choice of PS1 or arcade music (maybe?) The compromise Reduced colour palette (NeoGeo = 4096 colours, M92 = 32bit) Reduced resolution (NG = 320x224, M92 384x256)

Can confirm - one oddball length one AND the other three exactly inverted Asia = top, USA = bottom in these photos That being the case, you DO have to change all the connectors, 400 pins + 400 more pins for donors, + 400 pins to solder back on. Way too much work for me...

Agree the only difference is those connectors - there are 4 connectors with 96(?) pins per connector. You dont have to change all the connectors of course (edit, see below I did not recall correctly, all 4 DO need changing). IIRC the Asia B board has one weird long connector, and 3 standard...

Sorry I cant help directly (being on the wrong side of the world) but this site has the part number details and liked to digikey and mouser options https://wiki.arcadeotaku.com/w/HRS_DF1B So if digikey are sold out you might consider mouser instead...
