    New dumb idea: building a Neo Print system

    You want to warm it up, but not cook it... So maybe something like a hairdryer or a heat gun / air station on very low for a minute should do the trick.

    FS Selection of Jamma boards (original's and boots) Including some nice data east.

    Post is 6 years old, board was repaired and sold for 50 in the end. I'd like to also take this opportunity to announce GG's on selling regular boards, it's not worth the stress these days. If these posts keep getting bumped, i'm going to have to ask darksoft to lock them. Actually it was...

    New dumb idea: building a Neo Print system

    As you say, this dump is also suspect.. At this point for me, it's hard to tell, both are missing some data but it seems to be there in the other dump?! :) Does it also verify OK if you take the chip out / put it back in? Maybe it's also worth trying the heat trick, to see if the data changes ...?

    New dumb idea: building a Neo Print system

    It's actually slightly better dump but still repeated , does your programmer detect pins? if not can you try another eprom reader? There's other tricks to try such as heat / cold to try and get a good read....

    New dumb idea: building a Neo Print system

    Thanks for the dump! It seems P1 is corrupted, can you try re-dumping as 27c4096? Cheers! Also for these 2 slot neo prints, one of the slots is for the "main cart" and the 2nd slot is for a "red label cart" The "red label carts" are only add-on content and require a normal game in slot 1 to...

    ZN1 & 2 Bios & Romboards by Hammy

    Also now @Darksoft has re-done the acclaim sound board, NBA jam EX should be easy enough to do but would also require a custom top board.

    ZN1 & 2 Bios & Romboards by Hammy

    It's WIP hardware, everything works but it's hard to explain due to the number of bios sets / variants. Slow down a bit , take your time. Especially on rom burning 322's they fail sometimes. A lot of how it works is hard to explain, but easy to understand, MAME has the games grouped into the...

    ZN1 & 2 Bios & Romboards by Hammy

    No, the bios is separate / done, taito bios is accessed by adjusting the switch. The 2 smaller files are for the smaller chip sockets, they can be combined into UPROG to get the chip number down. Small sockets use 27c801, big socket use 27c322

    ZN1 & 2 Bios & Romboards by Hammy

    All you need to do is download the files of the game you need and burn them off / set the sockets up on the romboards. Most games are 2 or 3 chips so it's not worth populating all sockets. Files will have 217,218, 219 etc in the file names , this is for the socket numbers. The bios switch...
