    Toshiba PF picture centering

    https://www.arcade-projects.com/threads/toshiba-pf-d29c051-firmware-dump.17109/ The TL;DR The MCU has a programmed ROM from the factory. There are One Time Program versions of the MCU that could in theory be programmed as a replacement. I had tried to dump the existing MCU and have not had...

    Toshiba PF picture centering

    Yep that all looks spot on, which is somewhat disappointing as it is indicating the issue is with the MCU itself. Not sure where else to go with troubleshooting this. One thing I will note, that when I select the 'Reset' option - I have to highlight the option, then hit the up + down + func...

    Toshiba PF picture centering

    Can you check pins 15, 14 in a similar manner. Pins 16, 15 ,14 are all used for the remote control board. I believe all those pins should be pulled up to 5v. I 'think' the connection is as follows: (Remote-41) pulled up via RA14 (Remote-40) pulled up via RA12 (Remote-39) pulled up via RA10...

    Toshiba PF picture centering

    Yes, MCU-16 is the 16th pin of the MCU chip, the one directly next to the resistor. You can see the silkscreen pin (1) and (21) on the PCB, so that should help identify pin 16

    Toshiba PF picture centering

    Did you happen to measure the resistors RA12 and RA13 in-circuit ? (Did you measure them while they are still soldered to the board) I am guessing that would explain the difference in resistance. You want to verify that MCU-16 is getting pulled up to 5 volts, take a DMM and measure across...

    Toshiba PF picture centering

    You can see roughly center image is the remote board connector (notice the silk screen '42', '41', '40', '39', '38') and the MCU is upper left. Remote board pin 41 looks like it goes through a wire jumper (JP077), then a resistor (RA15) on its way to MCU pin 16. Also looks like it might get an...

    Dodonpachi saidaioujo Conversion sold for 2500usd

    @LinkArcade Here is a way to loose money and gain back some credit. Or if you have contact with the seller still, maybe see about releasing the dump into the wild and save @buffi the hassle.

    Toshiba PF D29C051 Firmware dump?

    That is really odd, I have never seen the remote needing to be attached at all, let alone getting the hieroglyphics. I know in the datasheet for the MCU, the OSD has a lot of characters available, including glyphs, sounds like you somehow got into that part of the MCU memory. I have been...

    Toshiba PF D29C051 Firmware dump?

    I did build the adapter and it does seemingly work to read the OTP chip (TMP87PS38N). However, still no luck with dumping the test MCU (TMP87CM38N-1H55) or the MCU off the PB-9929 (TMP87CK38N). When I dump the OTP chip - I see sections of all 0xFF and some sections of other random hex. I am...

    Astro City MS-8 only turns on after power cycle, any thoughts?

    Was the big filter cap that is on the B+ changed as part of the re-cap? Generally those large filter caps are not included in cap-kits and need to be purchased separately. I am wondering if the B+ is coming up too quickly and throwing the chassis into HV shutdown. Only after being on for a bit...

    Hello from SoCal. Diving back in, after a long absence :)

    @fatherpain Thanks for hosting such a fantastic meetup. It was great catching up with friends after such a long time, and meeting some new people as well. Can't believe you added a Commando to your lineup, as if the arcade needed to get any more awesome. Pretty pumped that just as we are...

    Hello from SoCal. Diving back in, after a long absence :)

    Thanks to @fatherpain I discovered several games I knew the names of but never got a chance to really enjoy. Anytime I would find the game in the wild it would be either a busted ass cab or emulated. His cabs are all pristine examples of how the games were intended to be played. Really glad to...

    New CRT monitor purchases as of May 2021 - Do you know any good sites?

    Oh right, if you already have a NNC with a monitor, then you got the chassis part solved. The DY you could reuse, but I had had pretty bad luck getting the stock NNC DY to work with other tubes. (A68LZU185X) - I must have tried it on 3 different 29" tubes and could always get close but the...

    New CRT monitor purchases as of May 2021 - Do you know any good sites?

    If you want a really high quality replacement monitor for the NNC you have to build one up yourself. Its a process of hunting down a PFX or Toshiba chassis while at the same time doing your tube homework. There are several flat 29" tube #s that will work for the NNC, each of those tubes #'s will...

    That Salamander cab with the early Konami logo looks amazing. You are working on some really cool cabs, color me jealous. Looks like you got that monitor pretty dialed in so nice job! Keep the progress pics coming.
