bump.

When I got this machine 5 years ago, I always wondered if I could fit a shifter. When I adapted an Outrunners PCB for RM I kinda missed the opportunity to shift and even started building a radiobox which I never finished. With the Slipstream Conversion I recently managed to do and the gear...

I can have a look at my board this month. So, some updates in general: I have 5 dead Naomi PCB's here. 2x old revision with the second large big heatsink that was used for HotD2 and came with the metal cage 3x newer revision board in plastic housing I just decided to give it another go and...

Necrobumping this. I saw another thread where Ken talked about the existence of two different package sizes depending on the version of cart/system/dimm. What package type are the 16-bit buffer ICs?

Bought Rad Rally from Jojo and what can I say? It's not Rad Rally anymore! View: https://youtube.com/shorts/OwZOAhS8gRs?si=G_gyr4LMMv5rrWHL Board is working great and came well cushioned! Communication was great. If the Cool Riders wasn't so expensive I'd buy in a heartbeat again! ;)

Thank you. I wasn't aware that these are non jedec and the rom map from mame says 27c010. Finally got it to work properly!

Any updates?

Sorry for double posting but I finally managed to convert a Rad Rally. I have no 27C010 or Equivalent here. Programmed it to a 27C2001 and wired Pin 30 to VSS and burned it like 27C010. Reads fine, SND01 also but I have no sound. PCB is working fine with Rad Rally or Golden Axe 2 Romboard. Any...

What a great project! So, after all I could revive the motor in my Rad Mobile DX cab with a modern solution while retaining the System 32 motherboard? I once came across a 839-0341 pcb from Marocco and pulled the trigger, but I have not yet had the will to test it as my PSU looked shot.

Up!

Any chance you could tell me what Eproms to use? Or anyone else?

Let me know once you've tried if it helped. ;)

Did anyone attempt to blindly replace the usual RAM? IC16,18,20,22? I got two of these revisions and they do not boot. Fans spin, voltage is there.

Definitly check the voltages first. N2 is possibly dead because of overvolting it.

Is Ken still active here? Got an Naomi 1 Rev. D board with all factory repairs except the one that runs to the Diode and the X76F100, both Fans spinning but not booting. All voltages are good and most importantly the LED's DO NOT LIGHT UP! What could this be? IC 41 and Bios are all good and have...
