    Hallo.
    I can get a Barco Graphics 800 from 1989 for under 500£.
    Any reason i should not buy this?
    This will be my first PJ and i cant afford much moore at the moment, but i can wait if it's not worth buying.
    It's included a screen and ceiling mount. I have sent the seller some questions about the screen, cables and tube wear. It's on QXL so i know it's a risk involved, but yhe price is tempting.
    Will It take Progressive scan? I will probably buy a Denon DVD 3800 later this year, so it's almoast a must.
    Thanks

    If it's not trashed then it's great. If it has a worn out tube or tubes then it's pretty worthless except for spare parts. The cost to replace the tubes is probably more than the end value of the product. If you can't get to see the thing working to confirm it's performance then try and get a money back guarantee (otherwise you'll have to accept throwing away £500, which it sounds like you can't...and who would!)

    It'll accept prog scan signals no problem. Used on a 16:9 screen you're probably looking at 800 x 600 resolution once it's dialled in. IFf it's in top condition then maybe even up to 1024 x 768. It will not accept COMPONENT signal though. Pretty sure it needs RGB signal for progressive. You should also be aware they are huge.....

    I know it's huge, but thats no problem.
    Progressive thru RGB will probably be a problem, don't think the Denon can do that, only component.
    This will be a temporary PJ, going for a better one later, in a couple of years.
    The bid is about 330£ at the moment with 3 days left.
    Will it be better to wait until i can afford a BG808, a year or two?

    808 is different kettle of fish. Much higher spec.

    Don't get me wrong. An 800 or 801 should produce a pretty magical picture when set up well and if in good order. It's just a bit risky. You could get a transcoder from Key Digital to do YPrPb to RGBHV conversion for $300. Or you could buy an Iscan which will make ALL sources better......

    I have a Sony1270 at home just now. Same tubes as the 800 I believe. It's great. (easier to set up as well I think). If the thing is working it's a bargain! The 800 in the pics I posted had a problem where it drifted by about 2mm every day. I didn't have time to fix it so sold it to a forum member for a good price. If you do a search for posts by Orbital you should find him. Ask him how he's getting on and whether he thinks it was worth it.

    Good luck!

    Gordon

    Do not fear for I am here!!!! :D

    Yup I have still got the very same BG800 as Gordon has in those pictures :) Does it still drift by 2mm every day? Sure does. Do I care? Do I **** as like :D It takes 10 seconds to put right and the picture is just dandy again.

    It was easily the best wedge of cash I've spent in ages and I'm sure if you get the PJ for the right price and it's not a ringer it will more than tide you over until funds are available for a 808 or something similar.

    Cheers

    Dave

    P.S. I'll post some pictures one day of the room now it's all finished Gordon. See what you think :D

    Magking, Were you looking at the one on ebay being sold by hoody34. If so the seller has loads more in stock.. everything from 708's to 808s

    I purchased a Barco Graphics 800 from him for £600 on sat. absolutly mint. Less than 2000 hrs on the clock and no burn..

    It's a great projector to start out with but you must be aware of the size and weight.. Not the sort of thing you can install on your own..

    Anyone know where I can get some cheep scafolding from?:).. I cannot ceiling mount the projector as I live in a rented flat but I want to construct a scafolding frame to do the next best thing..

    Lo all,

    I did exactly that. Install it on my own :D all 64KG of it!! Well when I say on my own it took four of us to lift it up to the ceiling mount and my Dad to guide it onto the lugs but no specialist tools used just manpower :D The difficult part is getting your mount in correct alignment to the screen, but again it's not rocket science. You just need to take your time and check everything you do and then it's chock's away!

    Cheers

    Dave

    Wheres the cheepest place to purchase ceiling mounts?

    Lo again,

    I bought my mount from a place in the States called Projector Systems and it does the job just fine. It cost about £250 altogether which compared to the Barco one is peanuts! I think there's is about £750!! (Roland would know better than me) But the Barco one can move a fair bit all directions which would help a lot if you've got your measurements a bit wonky :D

    Cheers

    No not the same, I'm looking at QXL in Norway. But it's now sold, so i'll just start looking again, but it's no rush.
    Thanks for yhe help anyway, it might show up a new 800 one day. It's a 808s for sale now, but it's close to 3000£ and that i don't have. Not yet anyway.

    Ceiling mounts are available from crtprojectors.co.uk for a lot less than the price above, look fairly simple.

    You can hire a lift from HSS hire shops or similar. One day i will get a CRT maybe, size is the problem though.

    Just finished mounting my Data 800 in the single garage which is now our movie room. Fortunately, I had a bracket from a 600 which was just re drilled to allow nuts and bolts to marry up to the 800.

    You could lag bolt into the joists and bolt directly to the 800.

    To really make an 800 shine, try a quadscan scaler. This will accept the YUV input of a non progressive dvd and output XGA. I can get a refresh rate of 48.7 khz, and no visable scan lines on a 7ft wide screen.

    Regards

    Nathan

    I will probably be mounting my projector (Barco Graphics 800) on a scafolding stand or something else that can handle the weight.. I rent my flat and my landlord would probably object to me ripping the ceiling apart to reinforce it..

    My problem is how to attach the projector to the scafolding.. I could purchase a proper ceiling mount and use that but it seams such a waste..

    Is there anything wrong with mounting the projector by screwing bolts directly into the metal bars that line the underside of the projector?

    Your help/suggestions is apreciated.

    Assume that it must be overhead and not floor mounted, suggest that you bolt through the existing holes in the bracket already on the projector and then U bolt corresponding metal plates to the scaffolding.

    Do not know if yours is the same as mine, but we used dead man's handles and wooden blocks to support my Barco. It only took minutes to get it ceiling mounted.

    Regards

    Hi all,

    The mount from crtprojectors.co.uk doesn't seem to offer much in the way of adjustment once the projector is mounted. This is what you pay extra for with other mounts. The one from Projector Systems enables me to tilt the PJ up and down by about 20 degrees and also move it forwards and backwards by about 4 inches either way. This can be very useful for fine-tuning the installation when you've got the PJ up there. Not all ceiling mounts are created equal you know :D

    Cheers

    Dave

    Orbital,

    its a good point you make about the adjustment on the bracket. Like everything you pays your money and takes your choice. The adjustment must be useful when trying to get things set up accurately to a mm. Maybe one day i wll have a CRT and have to face these problems.

    Is this convergance having to be done once the PJ is warm. (ie do not converge a projector untill it has been displaying a picture for at least an hour.)

    If this is a horizontal movement of the whole raster each time I would suspect the raster shift is set too high.

    Go to your normal convergence on red menu and look at the figure for Raster shift when you try to make your 2mm adjustment. If this is between 40 and 60 then ok any higher and I think you have some settings fighting each other.

    Hi there,

    Something like a BD/BG800 is an excelent starter projector....i have a bd800 linked to a htpc and get an excelent picture from it

    I used to live in a rented flat, and so mounted the projector in table top mode on a meter high home base rack (the kind of pine slat bolt together thing) which while a touch wobbly wasn't too bad in actual use. The rack was behind the sofa, so we sat underneath

    http://www.darkwave.org.uk/~lee/homecinema/cinema.html

    Has a photo of what i mean.

    BTW when i ceiling mount the projector in my new house i'm going to look at making my own bracket 'cos £250 is quite a few DVD's....

    cya,
    Lee
