Hi Gents.

Recently picked up a non-working project Time Warp and plan to get it back into good working order.

1) Backglass is OK,
2) Cabinet in good condition,
3) 'Wizard / druid guy' and a couple other areas on the playfield need touch up

So far I have replaced several blown fuses and am waiting on my order from GPE to bulletproof the boards ( The capacitors seem to be original and the some of the end caps seem bloated).

The game boots up into Test mode 4 (shows #of machine top left, and 4 00 on the credit display).

I can cycle through all tests (1-4), all coils fire, lamps work, flippers, etc - I change max credit to 00 (on test 4 18) to set for free play, new batteries installed on mpu.

Turn the machine off then on again and get nowhere (machine boots to test mode 4), when I check test mode 4 18 (credits show 20 again as if memory is not retained).

All the dip switches are moved over to the right (is this correct?)

Thanks,

WP

Gnatty will do. Thanks.

On a related note, I also put in an order for a couple of NVRAMs from Pinitech - am most likely picking up a Williams Phoenix tonight for cheap.

So I was looking at the MPU more closely to see the 5101 Chip. Prior owner must have installed a new chip (per photo). Could this chip be the cause or is it comparable to a 5101?

That chip is in a dip socket though. Thought the majority of chips on the boards were float soldered from the factory per Vid's Guide:

In any case, my order from Pinitech arrives on 9/10 so I will go NVRAM. My order from GPE just arrived so now I can update all the capacitors, resistors, etc.

Will report back afterwards.

Thanks @dothedoo for chiming in.

Playfield looks outstanding. Also, like how you incorporated the blue arrows and translucent blue pop bumper bodies.

On a separate note, do you have any playfield scans of the double snake and/or space wizard / druid? I have some areas where the paint is gone in that section and want to make some waterslides.

Well Gents,

Happy to report that my Time Warp is working almost 100% (need to adjust my left target bank - targets drop and reset when new game starts but does not reset during game).

I did the following:

Bulletproof power supply, cut battery holder off MPU and installed Pinitech NVRAM (I really like how these have a small footprint and almost look OEM)

Replaced resistors on driver board and fixed cracked solder joints on all boards (didn’t find many), 40 pin looks relatively new so I didn’t touch it.

As a follow up, I will be making labels for the MPU and power supply, replace the capacitors on the sound board, and do the bridge rectifier safety modification (just waiting on an order from Jameco.
