    PGM single game PCB interest check

    No idea ... I am still sorting bits and pieces - I'll try to start contacting people soon.

    PCB Feet

    Same here... for some I could clean the threads to make them useable. They were VERY cheap, though. :)

    Neo geo Kizuna Encounter 4p board

    It looks like I need to rework the PCB a bit, and get a new revision. Though while probing around yesterday I somehow managed to damage the VRAM, so I need to fix that as well ... sigh. BTW: I am 99% sure that the problems are timing related, though the HC/HCT should be fast enough up to 50Mhz...

    PGM single game PCB interest check

    It is not really a problem for me to finance them, and that reduces the risk for everyone. Don't worry, if there are no major problems with this revision it'll be relatively quick to reorder them and send them out.

    WTB: Atari Jaguar console only

    I still remember when my local GAME was selling them as cheap bundles (£10?) - though IIRC they only had sports games to go with them, so I didn't buy one at that time. I don't know if there were many exclusives worth playing? The only one I remember is Tempest 2000. View...

    PGM single game PCB interest check

    A batch of 100 PCB sets arrived today. I'll build a test set this weekend. - I am going to start contacting people starting at https://www.arcade-projects.com/threads/pgm-single-game-pcb-interest-check.9373/page-17 - Make sure you have your country in the profile so I can get an estimate of the...

    IGS PGM Motherboard Connectors PCB of the cartridge slot

    That is a standard PC/XT style 8-bit ISA slot. AFAIK it is a good idea to get a quality upgrade for them to improve cartridge connections.

    Espgaluda PGM problems: Either crashing or not booting at all with glitchy static

    There are two issues here: Power supply to the chips, and I/O levels. Power supply is relatively easy, you can use a voltage regulator to produce 3.3V from 5V. The tricky bit is I/O: As far as I understand reading signals output by a 3.3V system is no issue on a 5V system (TTL considers...

    PGM single game PCB interest check

    The PCBs arrive end of next week. I'll assemble one as a test, then start sending out PMs at the start of the list. Don't worry, I allow for plenty of time for the response.

    Any PGM Conversion info out there?

    Interesting, I just copied them from the existing boards. On some boards they go through a small SMD resistor network, so you don't get direct continuity if you check the connector. I think I traced all the PAx directly to the CPU.

    Any PGM Conversion info out there?

    Yes, that disables the bios ROM on the motherboard. Quick tip: Don't get ATF22v10 - they have a different programming algorithm, and some programmers enable the power save. Lattice 22v10 should work.

    Any PGM Conversion info out there?

    No idea... my PCBs were developed by taking everything but the asic communication logic from an original cart, then when I tried it without the 100Ohm resistor it didn't work. I assume it is a pull up to signal something to the motherboard. Edit: I think the Microchip site uses some script to...

    Any PGM Conversion info out there?

    Yes, that is exactly what the GAL is doing - at least on official carts. The BIOS expects the game to start at 1MB, so the GAL maps the address space from the PGM to the EPROM. (It also makes sure the game doesn't map over I/O area). This is how it works for DDP, which uses the motherboard BIOS...

    PGM single game PCB interest check

    Ordered 100 sets for now - I'll order more once they arrive and I get a feeling how well shipping works now.

    Neo geo Kizuna Encounter 4p board

    Quick update (you are not forgotten)... - if I connect a scope and probe the various lines I am getting the correct results - my test program running on actual hardware only works correctly for the first edge - I do think I know what the problem is, though I need to order some parts I had a lot...

    Update: I'll try to get them ordered this weekend, though I will not be able to start sending them out until September.

    Neo geo Kizuna Encounter 4p board

    Does anyone know what I need to look out for when running code on the real hardware? My test program runs in Mame, on my unmodded MVS I boot into a cross hatch screen, on my unibios board I get a black screen. Edit: As usual, found the problem RIGHT after posting... I am using a 27c160 (because...

    PROG-GSC Jumpers?

    In case anyone is wondering. No warranty. I didn't draw in all address and data connection, all EPROMs are just connected in parallel. Just keep in mind M68k A1 is EPROM A0, so all address lines are one down. And I didn't care about the V-ROM connections, though I don't expect surprises there.

    PROG-GSC Jumpers?

    Before I reverse engineer it myself, does anyone have a jumper table for PROGGSC?
