Funny what you find when you dig in the back of the cupboard.... I have a few old SP.ACE boards and one of them had a set of ROMs in it, turns out they are Twilight Zone, and from what I can make out they are a £3 set? Would appreciate if someone with better knowledge of the emulator could give these a go and let me know if they are ok. The verify good so here's hoping! Twilight Zone.zip

0.01/0.07ohm is really low resistance for open circuit I'd take another quick look Maybe they are short... Can't say I've ever checked they are in tolerance...what can go wrong with wire wound resistors... go open circuit and stop the lamps / 7 segments lighting up? Fix when something don't work. I think the only triacs are for payout on the bottom left of the board. The lamp multiplex is all DC so would be transistors. They look very similar but a triac is kind of an AC version of a transistor. I kind of work project Coin boards in the order they show errors… 1. getting the initial beep and reels start to turn at all. 2. completing reel initiation (slowly finding reel position flags then spinning the reels fast to initial game position) 3. going into attract mode (inputs and outputs relatively happy) and you get that short ting. 4. registers credits and spins off (coin inputs and start button OK) 5. Pays out fire. 6. all lamps working & Credit display working. 7. level sensors working & Everything else. Each step can have setbacks and I’ve learned some of the symptom combinations for errors through putting in plenty of hours. Then another one comes along and takes all week to suss… I’m not saying there is anything wrong with going over the whole board before trying to get past stage 1 and there is plenty of potential for fun before you get to stage 6. For me it feels like a win getting past stage 1. Like other tec you’ll find your own way and that’s what it’s really about for me… Then again some tips really helped me along the way when on other tec.

The resistor in the third photo says 'R47' which I think means 0R47 or 0.47 ohms. If so, your multimeter readings aren't far off.

Yeah the dongle isn’t emulated fully in mfme, all those rebuilds will show a bit of life but can’t fully boot unfortunately. It’s very likely you could find the dongle check and disable it if you spent a bit of time looking over the code, of course, it might not be so simple J

Best I can get it to do is boot this far then hangs with percentage on the screen.

This is probably the same but there could be something in here to assist. MPU 5 field manual 19-01-10.pdf

Looking in hex I believe this is the 5p BWB rebuild V03. It won't work in mfme as they required a dongle, this was never fully emulated in mfme sadly. J

Was a pleasure chris and glad you enjoy the machines

It's been a long time Since I played one of these. Thanks Massive to sulzerned for my invite today. Welcome to Roadrunner https://youtu.be/d6QPMAi3eq8

And the good thing is you only need the power plug in to test boot and speaker if you want to listen for the boot tone. Not lockouts so you don't need to work in the back of the cab. Make sure the keyway blanking pin hasn't fallen out of psu plug at mpu end!!! Glue the bugger in as they are known to fall out. I'll admit to killing a board being 1 pin out a few years back.

That custom near the crystal can be swapped for the daughter board. Think it's just 2 clock outputs which would be easy to check on the cro.
