My A500 "project" pics, details, build log?

As you are probably aware of, I made up a circuit that was basically the same as this device, and it worked on two other tvs that didn't accept 15Khz.

In fact, this TV with the scart input won't accept the Amiga input on the vga connector either...

Quoted from another thread, on another forum:

"The issue some TVs have is with the sync signal being the wrong type.  YPbPr video should have a Tri-level sync signal, the Amiga outputs a  normal bi-level sync. Some TVs will cope fine, others will not, it all  depends on the analog front end of the TV.

With some creative circuitry you could create a tri-level sync from the Amiga, that should help."

The three (make that four)TV's I'd tested all worked with this format of YUV signal.... I guess its a bit hit and miss...

I suppose someone needs to figure this circuit out.... :p

I tried to get the faulty A500 keyboard working...

Swapped out the controller board... half the keys don't work?

I dont remember if that was the original issue, as I didn't want to test it with the possibly faulty controller, as this motherboard also had a bad CIA chip, which I'd already swapped....

Hmm...

[AmmoJammo]

Now to figure out how to hold it there... other than double sided tape :p

[AmmoJammo]

Yes that's the A600.

Ah, hot glue would be about as good as double sided tape :p

Might try to figure out what plastic the case is, and find some suitable glue, so I can use the bits I cut out to make brackets, as I really need the drive removable, as the keyboard can't come out unless the drive it out

[AmmoJammo]

Master and slave connected to the internal ide header

[AmmoJammo]

Mmmm.. melted plastic! :p

Well, this drive doesn't work on the Amiga...

I had originally planned to use a slot load drive, but stuffed the cutout just for the slot, so went to the tray load instead (which cost all of $13 from memory)

However, I had been booting with the CF as slave, and the DVD as cable select, which made it a master....

This new drive doesn't work like that, and I've now cut the wire on the IDE cable to set it to slave, and it still doens't work...

However, the previously drive doesn't seem to work as slave either..... argh :/

[AmmoJammo]

I think I "twiddled" something months ago when I was playing with the settings, as I can't get any optical drive to work :p

Thanks for the link!

[AmmoJammo]

The slot load Panasonic drive, with the CF card set to "slave" and I can find them both...

Disconnect the wire to pin 28, which should set the dvd drive to slave (if it was cable select) and set the CF to master, and I get checksum errors when workbench tries to load...

I have to assume this drive is internally set to master, not cable select...

However, the new, tray load HP drive, doesn't seem to let workbench boot no matter the jumper settings....

:/ and workbench is all messy from various IDE CD software being installed, setup, and messed up :p

Bought myself a 24 inch Dell 2405FPW today! Should support the Amigas native 15Khz sync frequency, plus it has composite, component, and svideo inputs for all my old gaming goodness!

Haven't actually bothered trying it with the Amiga yet though, I just hung it all my wall and am using it now...

Its a pretty old monitor, but I figured for $70 it was worth the money.

[AmmoJammo]

Don't say that! :p
I'll have to plug in my Sega Mega Drive (via rgb), and see what happens...
