Thanks for the catch - I'll make that clear in the listing. I knew it didn't look like a "normal" CPS1 B board, but after looking at more pictures I see that it should say "Mitchell" next to the model number.

Clearing some space, getting some cash together for more parts! All prices include USPS Priority Mail shipping within the US, tracking will be provided. Prices listed do NOT cover PayPal fees, please plan accordingly. I'm happy to make a deal on multiple items. Currently, I am only shipping...

Very, very interesting. Thanks, y'all. I've got a DASH A-board that is currently dead-to-the-world. If I can't get it up and running after doing some troubleshooting, I can see if I can transplant the CPU over. Granted, the reason it's dead to the world could be that CPU so.... Otherwise, best...

I've seen some rumblings of a "crystal and CPU" pairing recently, as opposed to the straight crystal swap. Any ideas on an appropriate replacement CPU?

EDIT: Sent to auction!

B-board sold, feel free to make me an offer on the WW set!

Looking to declutter, first on the chopping block are my spare Street Fighter II boards! Prices are shipped within the contiguous US, no international shipping at this time. F&F preferred, otherwise please add 4% for fees. I have several positive purchases KLOV and can point to a few forum...

Swapped in a different 12 MHz crystal after verifying that my solder job was ok on the first one. No change. Swapped the original 10MHz crystal back in and performance went back to the "expected" stuttering of a 12MHz game running on 10. Very strange. I might order different 12MHz crystals from...

I've got a couple naked B boards, would like to find 2 shells for them to live in. More concerned about condition than I am about color, I'm actually thinking about maybe painting one for a repro. Only looking to buy from within the US or Canada to shipping costs low. Would also consider...

Don't get the wrong Idea - I simply removed roms from working B boards (one had a good C board, the other had a bad C board), set everything aside in antistatic packaging, and burnt roms for those respective titles. I'm using SheepNova/Lydz generic B-21 C boards. No games were irreversibly...

I have both a 10mhz and 12mhz CPS1 short A boards. I've recently made repro 1941 and Daimakaimura boards for myself, so I opted to upgrade the crystal on the non-DASH board to 12mhz. On either of these games, there would be a light stuttering or slow downs on complex scenes. Both work flawlessly...

Here's the thread I used to build mine (and where I did my troubleshooting). There is another angle you can take, which gives you more options for the B board to use as a donor. It was a bit more involved than using a SF board ...

Ohh that's right, he's in AUS. Well for the first time, I can honestly say: lucky him for living in AUS :P Please don't give me THE BOOT, my Australian friends

Wasn't shipping on them from China to the US super expensive? When I priced them out on TB, it came to about $29 USD after shipping for one - "coincidentally" the same price shipped on eBay.

What a roller coaster, but I did get it working! I can confirm that the MAME rom works as-is with a 90629B-3 B board I used an unmerged copy of daimakair No patching necessary - generic B-21 C boards work fine Turns out the C board I was testing with died during testing, luckily it was one of...

If you're still looking to buy, I've bought several different lots and types of EPROMs from jk_parts on eBay. SpeedPAK shipping so it's well tracked, arrives reasonably fast, and I've never had an issue with quality or misrepresentation. I just received some M27C4002 yesterday that have been...

After reading through aje_fr's thread, I think it's best that I start fresh. I'll burn a new set of ROMs from the resale set noted in AlxUnderBase's previous post (I'd dump and CRC against the set Alx used, but it's probably just as quick to reburn and erase the old ROMs for later reuse), then...

Oh I must has misunderstood. Thank you for the heads-up!

I'm fairly certain - the solder mask on my B board matches what MostroVeneno showed in pictures of his 90629B-2: the "top half" of the graphics section calls for HN62404P-N (so those would be 27C400), and the bottom half of the graphics section calls for HN27C4096 (noted earlier in the thread as...

Man - I'm trying to get this working on a 90629B-3 with some issues. -I'm using the resale ROM set (I've tried both the merged set from MAME and a non-merged set from some rando site) -I've tried both stock and "protection removed" program ROMs (generated from the ROM patcher on UKVAC) -I've...
