    7800

     

    I got the boards from Albert and I'm able to verify the 7800 connections. If you've got a NTSC Rev A, just follow the picture. Works great in both 2600 and 7800 modes and you don't have to cut or remove anything. RF output will still work too.

     

    The Atari 400 sound boards should be here this week and after a little testing, they'll be made available.

    If each wire was marked with a different color this would be the best set of instructions available.


  2. NEW PROBLEM--I have an 800XL that doesn't boot. When I turn it on I hear a click like it is going to boot but nothing else happens. I have swapped out every IC, it will not boot with Star Raiders and I get no video using SYSCHECK.  When I was swapping out ICs the ROM was bad and 1 RAM IC was bad. I also believe someone had tried to work on it before because most of the capacitors did not have the same voltages as my stock test machine.


  3. I have never had any issue with Best Electronics. Brad is helpful when I don't know exactly what I need and tries to make sure that I get the correct part for the particular computer that I am working on.

  4. I don't know how I can explain it in any more detail than I already have. The computer with a UAV doesn't work with the cvbs connector on the flat screen TV, it does work with the composite connector on the Dell monitor.  The computer with a Supervideo 2.1 upgrade works with the cvbs connector on the flat screen TV and it works with the composite connector on the Dell monitor.

    same cord used for all connections out of the same output of the UAV /  or are you saying something from the other Atari outputs... I don't follow. there are a couple of threads that speak to using a differing wiring/jumpers of he UAV by revisions as well as weather a person leave the 4050 in or not

    Bottom line, the computer with the UAV gives me a composite picture on my Dell monitor, it does not give me a picture on the flat screen TV through the CVBS connector.  The same computer gives me a picture when I run my composite video through a converter with a HDMI output.  A different computer without the UAV gives me a composite picture on the Dell monitor, and on the flat screen TV through the CVBS connector, and through the converter.  Both computers using the same power supply and same AV cable.


  6. I just installed a UAV in a 130XE and decided to see how it looked on a flat screen TV; when I hooked it up to the cvbs connector I got a "no signal" message on the TV. I get a composite picture on my DELL monitor and I when I go through a HDMI converter with composite I also get a picture.  Another 130XE that has the SV 2.1 mod gives a very good picture on the flat screen TV. Does anyone know why this happens and is there a fix.

    Just don't mount an image in slot 1 - then you can boot off a real floppy, and save to the image mounted on drives 2, 3, 4.

    How do you boot from a real floppy, the computer automatically goes to the SDrive when it's turned on.


  8. The SDrive and the SDrive max would be infinitely more useful to the casual user like me if you could designate it as drive 2 then if you were using a word processor or spreadsheet program you could save the files to the SDrive.  There may be a way to do that with SpartaDOS or some of the other DOSes but I am not familiar with them.

    Hello Peter, 

     

    some DOS need to be configured to be able to have more than 2 drives.

    You can copy files to the SDrive but once you have done it I'm not sure how to access them.
