Sorry for mistypes from my android. Yes 68000... and.. I have a UV eraseer for EPROM. Is been reprogramming eproms for years. Thx for the info

I know you can buy "unlock" sets for $40 that include a 6800 chip and a few of the eeproms Can't i just use any 6800 and program those same eeproms myself?

I bought a "Bad" Outrun board on ebay. and mix and matched parts and i now have a working Outrun board. A) Turbo outrun (my original set) B) Outrun (from ebay) Used B Rom's from video and CPU boards Used A Main board Used B Video board Funny thing was the B (ebay) board didn't have a...

Just re-verified all EPR and OPR chips with my GQ-4x programmer. They all checkout fine. Have re-seated each chip with DeOx... here are a few better photos now that it is on my testbed. does anyone have the manual for this?

Well replacing that Eprom did not make a difference. Any other thoughts?

I'm going to say no. because a few days ago I was wondering if one of my NP's were bad and I swapped their spots with same issue.

Yes sir. That fixed it. Wow i just replaced those with my cap kit. My guess was that my 162 NP from the capkit was bad. Problem Solved!

I'll hope they are all in tip top shape.. and move forward with the one I know is bad. Thanks..

28 Pins. Thanks again for the help.

Sorry i think there was a misunderstanding. The chip that doesn't Verify against the MAME roms i have is EPR-12293. which when i romident it i get "681b2254 NOT FOUND" But when i romident a few other roms from the game board it does ID them properly. Guess i need to order a 27512 chip...

So.. is this a chip that can be re flashed/replaced without affecting the suicide battery ?

12339 sorry!

8909 mpr-1239 t36.. sorry i deleted it, but since i was able to read and Verify the chips i didn't want to wast anyone time.

Actually the MPR chips on the Turbo outrun board read and verified using a "27512" setting... I have tested every Eprom on both board and one come back bad.. "EPR-12293" its an intel 27512. Now this board still has the FD1094 317 chip with a updated battery. Can i just replace the EPR...

S0 This is an upright game. But i'm not sure it's the original board. how do i tell which romset i have so i can compare rom's on board to a mame romset
