When I adjusted the width of the image with the coil, it self-destructed. This one cannot be found, so I made a splint printed in 3D.

Hello all, I bought a set of NOS sideart for my maddog II. I bought it but it's not for the right version for me (I have the 25 "and the Sideart is for the Dx). Does anyone want the HD scan to clean it? After he will do what it he wants as long as I have it too;)

There's an issue on reset. I've to correct it. The test rom work fine only on power on.

You use the old midway version. I don't know this version very well. Why don't you use the 1.2 version?

watch this video : ZjGHKQToZKg

I never use it on taito board. let me know if it work

You have to program and use the test rom

Hi all, I've update the space invaders test rom to v1.2. It's available on the timothy's server : http://www.outerworldarcade.com/arcade/space_invaders/space_invaders_test_rom.html The news are : - Modification of the test RAM to display all rams in error in one time. - Correct a display bug...

I've forgot somes modifications : on the top board, let the strap near R23 to 512 and set the strap near IC94 to 256 on the bottom board set the strap near IC32 to 256

On my passing shot board I've this PLD : on the top board : IC20 ck2605 = 315-5141 IC57 82s153 = 315-5149 IC69 82s153 = 315-5244 IC76 ck2605 = 315-5142 The custom board 171-5468 instead of the 8751 on the bottom board : IC20 ck2605 = 315-5144 IC35 pla16r6 = 315-5108 IC58 pla16r6 = 315-5107...

It's work with a 315-5244 ;) I've repack the roms to be compliant with the address decoding : epr-7385.43 + epr-7386.42 were burn in a 27c512 which was inserted on support IC43 epr-7382.26 + epr-7383.25 were burn in a 27c512 which was inserted on support IC26 epr-7387.41 was burn in a 27c256...

The full schematic is here : http://www.jammarcade.net/files/PDF/System16A.pdf

I didn't want to say that. Maybe that's my English skill :( I think that maybe : The 315-5150 allows the use of 0x8000 size PROM The 315-5244 allows the use of 0x10000 size PROM I'm pretty sure that the solution is to have a correct IC69 (315-5244 on my Passing Shot, 315-5150 on the fantasy zone)

I've the same result as ifkz (see pictures). caius, yours equations came from a 315-5150? I ask that because the file generated by Porchy made the same bug as my 315-5244... The chip is an ATF16V8CZ and I've burn it with a galep-5.

Yes I can test. I'll will order Gal today
