What is the going rate for a Time Pilot? Is it an original?

BUMP!

Would it be possible to remove all the hacked in wires and burn Radar Scope roms to take this pcb back to it's original state?

You'd have to ask Scott Brassington (maker of the hi score kits) - but I guess it would work, and it may turn your game into the US version?

Look for cold (cracked) solder joints too.

As the machine warms up, the connections of the components get better - may be why your machine improves after being on for a period of time...

John - Can you post the picture of the Sky Skipper Cocktail please>

Don't suppose you have a decent pic of a Mario Bros cocktail too, do you?

I am converting a Space Fever (no.2 of 3 I have) to a Mario Bros very soon.

It has the Jap roms - if you can burn eeproms or know someone who can, you can change it to the US set.

If you don't have that hold pot in the correct position it can start up like that.  Give it a (careful) twiddle!

Make sure you haven't damaged any of the legs on the chips when re-inserting them and they are all in the correct way around.  Look for the notches on the chips.  You should have also re-inserted them in the same positions as you removed them - but you probably know that already!

Maybe someone should do a port of Fix it Felix Jr?

If they do - I'm getting one!

Sounds like one of your colour input wires is loose / not connected or one of the colour transistors on the neck board has died.  Get the teswt screen up on the 60 in 1 and see if either red, green or blue is missing / incorrect.
13  Tech and Marketplace / I need help with my game! - Technical Discussion / Space Fever Lines on Screen on: January 16, 2013, 02:55:07 pm
I recently got (another) Ninty cocktail to gather parts for a Space fever resto.

I now have a pcb, but it just has bars of coloured lines on the screen.

I have been told that it may be one of the 4116 rams or an ls174 that is the problem.

I probed all the rams in the line to compare and one of them at I5 is different on ppin 14.  I am just about to whip it out, fit a socket and try another 4116 ram (that hopefully works, but has not been tested)

Anything else I should be looking for?

That would be me, Virtvic - long time member of J+

We must have met at the old Barn possibly?

Nice get on the 'tent though.  I really like them, but don't ever recall seeing one in the flesh.

They kinda remind me of these (I'd kill for one!)

15  Tech and Marketplace / For Sale / Wanted / space fever colour pcb on: January 16, 2013, 06:27:55 am
Not wanting to jump in front of chuckie egg's wanted post - he has a b&w space fever cocktail.

I am specifically after a colour pcb as mine doesn't work (at the moment )

I'd still like a spare even if it did though.
