So we’re within the residence straight right here with the Gravitar. Not a lot left to do, however I wished to doc these final bits right here on the weblog.
So I do know what you’re considering. The featured picture is of a Area Duel, not a Gravitar proper? You’re appropriate. However there are causes for that – learn on to seek out out!
So in Half 2 of the restoration the cab was in the home and we had been making good progress on rebuilding the Gravitar. Right here’s the ultimate levels for you:
The coin door was changed as this was the state the outdated one was in. No going again from there I feel. The brand new door is behind, with elements from a donor door that I had mendacity aroundThe coin door wiring wanted a number of repairs, earlier than I might hook up my bulbsThink I discussed beforehand that I had utterly rebuilt the WG6100 monitor. Right here’s the naked chassis earlier than repopulating itBit of a facet word whereas I’m right here – I observed a jitter on the display screen after I plugged it in, and determined to exchange all of the body transistors to see if that might repair it. On eradicating the outdated ones, I observed one of many sockets was disintegrating, leading to a brief from one of many transistors to the body. After alternative, the picture is rock stable. A very good end result!
Subsequent up was reinstalling the cleaned up wiring loom, coin field, energy provide, coin door, PCBs and monitor:
Right here’s the facility block. All restored with new “Large Blue” capacitor and fusesPCBs, loom, speaker, coin door and coin field all inAnd lastly, the monitor was dropped in on the high. Trying good!
A very good hour was spent doing this – it’s value being methodical about this, it’s very simple to overlook to attach one thing. Take one job at a time – I are likely to work from the bottom of the cupboard upwards. After a closing flight test and a double-check that all the things was accurately, it was time for the massive change on:
Gravitar from the leftAnd the appropriate!
There was a small problem although – I had half the sounds on the sport lacking for some motive. So the PCB wanted to go off for restore.
However right here’s the twist – I had a Area Duel package. Area Duel shares a lot of the facility schematic and harness of Gravitar, so in concept it’s a easy case of swapping out the marquee, management panel and PCB. So I figured I’d try this – at the very least I’d have one thing to play whereas the PCB was on the restore store.
You’ll additionally discover that there was no marquee gentle. The rationale for that is the incompatibility of the ballast in my US cab, with UK electrics. I gained’t go into element, however suffice to say, dropping a local UK fluorescent bulb right into a US setup will end in an immediately blown bulb! There’s couple of the way of fixing this drawback, one among which after all can be to swap out the ballast with a UK one. They aren’t significantly low cost, and I wished to experiment just a little with an LED answer, which might be useful for future reference:
It’s a fairly easy conversion. Briefly, it’s essential utterly bypass the unique ballast and starter motor and wire stay to 1 finish, and impartial to the opposite. We are able to maintain the prevailing lamp holderAnd right here’s our new LED strip. It seems precisely like a flourescent bulb, however with low warmth LEDs! I ordered this from a Chinese language eBay vendor for the princely sum of £7 shipped! It’s a pleasant high quality product, and arrived in a few week as I recall.Dropped within the Area Duel marquee – excellent. Simply the correct amount of glow, and no proof of LED “Dotting” that you simply would possibly count on. More than happy with that, and really useful to know for future restorations
So right here we’re – the completed article. One Atari Gravitar, with a Area Duel package put in inside:
It seems nice! The paintings actually popsHere’s the appropriate hand facet. As a two participant recreation, Area Duel works very well. The cab is sweet and large to accommodate each gamers with none issuesYou can see simply how tall these late Atari vector cupboards areI’m significantly happy with how the entrance black vinyl cleaned up with out having to get replaced. You must be capable to make out that I made up a matt black kick plate to cowl up the cracking on the backside. It tidies it up very well. The coin door was utterly replacedAnd right here’s a fast earlier than/after shot. I reckon that’s a job nicely executed
So there you will have it. I’m attempting to work out how finest to mount a credit score change, as Area Duel‘s “freeplay” mode doesn’t present a number of the appeal to sequences, and simply sits on a static display screen ready for the participant to start out, which I discover tremendous annoying. I may also revisit the t-molding. The usual dimension doesn’t fairly match, because the cab has swollen with age – nothing unhealthy. It’s nonetheless stable as you possibly can see, however I think the particle board has drawn in moisture through the years – most likely all the way down to being saved someplace chilly. Barely wider t-molding is offered which might type that, so I could order some and change what I’ve on there.
Right here’s the cab in situ within the loft arcade to present you a way of scale:
And eventually, since I wrote this piece, the Gravitar board is again all mounted. I’ve reinstalled the package, and right here she is:
The finished Gravitar!
Proper, I’m off to play some vector video games! If you wish to look again on the full restoration of this cupboard, go right here.
Thanks as at all times for studying this week.
