This is not 56k friendly, so please if someone wishes to copy images and make a PDF I would be grateful (as would the site owner (sorry Kev) I am sure).

Start with the base unit:
http://i138.photobucket.com/albums/q265/Parris1972/Bobs%20sitdown/DSC01037.jpg

And here's what should be inside it at this stage. A transformer, the Sun PSU, the amplifier, filter and leads.

Attach legs and thread through cables, attach earth wires and top cross frame for the lighting:

http://i138.photobucket.com/albums/q265/Parris1972/Bobs%20sitdown/DSC01038.jpg

Here's a close up of the lighting taken at a later stage:

http://i138.photobucket.com/albums/q265/Parris1972/Bobs%20sitdown/DSC01044.jpg

Add the monitor brackets top and bottom:

http://i138.photobucket.com/albums/q265/Parris1972/Bobs%20sitdown/DSC01039.jpg

...then add monitor to the brackets BEFORE you add anything else. It is hellish to stretch across the CP lower when you have a monitor weighing you down.

Wire in and tidy up:

http://i138.photobucket.com/albums/q265/Parris1972/Bobs%20sitdown/DSC01043.jpg

Then add the leg covers once all wiring complete. DO THIS BEFORE YOU ADD THE CP UPPER AND LOWER (you'll thank me for that tip!)

http://i138.photobucket.com/albums/q265/Parris1972/Bobs%20sitdown/DSC01046.jpg

Once both leg covers attached, get the CP lower on, then attach the upper. Some people will leave the upper off, but it never bothers me or gets in the way imho.

http://i138.photobucket.com/albums/q265/Parris1972/Bobs%20sitdown/DSC01049.jpg

So you should be at this stage and it's beginning to look like a proper arcade :
http://i138.photobucket.com/albums/q265/Parris1972/Bobs%20sitdown/DSC01051.jpg

Start with the wiring in and JVS I/O board, any credit boards, speakers and whatever is required:

http://i138.photobucket.com/albums/q265/Parris1972/Bobs%20sitdown/DSC01053.jpg

At this stage you can test whether everything is ok by inserting a Naomi motherboard and checking whether the sound and picture is okay:

http://i138.photobucket.com/albums/q265/Parris1972/Bobs%20sitdown/DSC01057.jpg

Test all the remaining electrics:

http://i138.photobucket.com/albums/q265/Parris1972/Bobs%20sitdown/DSC01062.jpg

Fit monitor cover / bezel and adjust the CP upper to the correct position (it can be moved around, so you want it perfect and then screw it down tight).

Check all locks before closing the CP upper if you have a CP attached otherwise you could accidentally lock yourself out and need to drill the lock out:

http://i138.photobucket.com/albums/q265/Parris1972/Bobs%20sitdown/DSC01063.jpg

The following images are taken with another CP, but clearly demonstrates that you next have to insert sticks and buttons:

http://i138.photobucket.com/albums/q265/Parris1972/Bobs%20sitdown/DSC01034.jpg

Then when complete and the new artwork is applied to CP upper, leg sides etc, then simply insert some cool titles like these two here (Zero Gunner 2 & Psyvariar 2).

Clearly as very basic guide and others have done much better, more detailed guides, but it does show that it's pretty straight forward. The first one I rebuilt took me hours as I had no idea where I was going. The most I have completed now is 3 in one day as I had to swap a lot of parts of some faulty units.

Very nice, dude - thanks for sharing. Despite not owning such a unit, I've long been interested in them (mainly for the looks more than the games available for the system, I have to admit - although you demonstrate two great games in the last photo; I've enjoyed the Dreamcast versions of both) and how they fit together.

Maybe I'll eventually pick up one of these and make use of this great guide. :)

They are not so expensive to obtain so long as you are prepared to do a bit of work yourself. The last one I bought was £150. It really wasn't all that great and required a lot of TLC plus some new parts, but these units are more cumbersome than expensive these days. Expect to pay anywhere between £400 and £1400 though depending on condition.

I have created a basic PDF from your post but i'm not sure where would be the best place to host it for people so if you or anyone has suggestions then i can upload it.

Cheers for that, I am not sure where the best place would be? Perhaps something like megaupload?

I was trying to temporarily upload it to my newer site but it too big in size although i think i'll upload it to megaupload. Also I will keep a copy on my comp so if needed it can easily be uploaded again.

So they convert to sitdowns? Man I passed on a lot of these in upright config.

Yeah, there are a lot of guides floating around to simply chopping the legs and side covers down, punching holes for cables and lowering the entire unit. I'd say it's a 2 hour job to do properly.

I've found a few good units (or at least they seemed to be good - not that I'd know) for £300 to £400, but I was put off by the lack of "interesting" games available for the system.

Plus, the few games that I did want to play (shmups and puzzle games - not a fan of beat'em ups) don't seem easy to obtain or cheap. Not that JAMMA boards of shmups are. :)

Then there's the lack of space... Heh.

If you struggle with the games available for the arcade motherboard, you could always purchase the cabinet, make sure you have a dual or tri sync monitor installed and go the MAME route, or install a Jamma harness and use another system. Actually, it is something a few people do and Ross has been helping me out with a MAME set up as I wanted to use some titles I owned on consoles in the unit.

However, you get the advantage of the authentic arcade feel on a nice sit down unit.

Actually, taking the JAMMA route was my original plan, but I then found the Insert Coin cab orders and discovered that an Egret II would be a lot less effort and a bit more practical - although not as good looking. :)

Not too keen on MAME, although I don't really know why. I just don't like the idea of emulating something when I could be playing the original, even though that's not entirely rational. After all, I enjoy the Dreamcast versions of Ikaruga and Zero Gunner 2, even though they're not the originals.

Having said that, I've been using MAME quite a bit these past few weeks to play some early Cave shmups - mainly DonPachi, which I enjoyed so much I bought the PCB. :) It arrived yesterday, but unfortunately my TV doesn't like being 'tated, so I've got to either play it side-ways or wait 44 more days. Haha.

Sorry - I appear to have derailed this thread a little.

No worries, I went for the Atomiswave cab, narrowly missing out on an Egret II as I came in too late. See you in 44 days! :nod:

Back on topic - here's something I've been wondering ever since I read those threads on discharing monitors: when disassembling one of these (or, in fact, any cab) -- effectively doing the reverse of what you've done here -- do you need to discharge the monitor? Or do you only have to do that if you're going to be messing around with the monitor itself?

Even if you are not going to be touching the monitor, it's a good idea to go through the same steps as if you were. Anyone can accidentally touch the monitor when it is lying around on the garage floor, so best practice is to assume it could happen.

Doh! And here I thought you were selling one (From the forum thread name). (^_^);

Seriously, if only you were in Canada / North America, I'd buy anything you rebuild in a second. Your hand are gold!

Ha! That means that technically I have the Midas touch and we all know what happened to him ;-)

Sadly, I don't think shipping would be possible to Canada otherwise I'd be only too happy to put together a cab for you.

There is always way. I would check the container shipping. Sometime you can buy a space inside and don't have to buy a whole container for yourself.

I've sent a few parcels to Canada and ended up having to write long pages of the content of the packages (the worst being an entire Nintendo dev box) and swiftly fell out of love for Canada Post!

I'm trying to imagine the paperwork involved in sending an arcade... :noooo:
