Isn't the black screen reporting a missing CPU?

This is the A1200 warning colour, maybe the 68000 is not sitting
properly in your A600.

Another problem could be the machine's SCART plug isn't in firmly in
the back of the display or something simple like that.

What makes you think it's the Kickstart chip?

The custom chips will still notify you of a component failure such as bad ROM by outputting a red screen to your display.

I once had a hilarious problem with my X-Box whereby the screen would only display in black & white in RF/Composite modes. After arranging for Microsoft to collect and re-deliver it 3 times, with them totally baffled (and costing them £60 with Securicor), I found out my TV's battery backup was dead and had forgotten the colour settings.

Obviously I didn't mean to cause Microsoft all this hassle and expense. Hehe

Maybe you should get another cheap A600 and swap ROMs to see, at least then you'll be able to eliminate suspicions and have a machine (with accesories!) for spares/sale.

demonblaze: I bought my X-Box in the blissful knowledge that Microsoft made a significant loss on all consoles sold in order to make the profit on games. I buy the games second hand.

:-D

I only got it for Jet Set Radio Futur but despite it being a lump of a machine it's a very good bit of kit (700Mhz Pentium, GeForce 3, 64MB RAM, 8GB hard disk).

The bizarre thing with the X-Box is only now is a console capable of having an operating system hacked onto it by coders and emulators etc. put on it. Even though people were doing much more with the CD32 SX1/SX32 nearly a decade earlier!

As for the A600 problem, yeah it would make sense there's no CPU-missing screen. The thread I read before must have had their wires crossed.

:-D

Wizard Developments (aka Compute!) had a dedicated setup to check for faults and I think there are machines or software that can immediately pick up on some lost signal or timing problem. Maybe AmigaKit.com has diagnostic software to avoid you spending the evening with the multimeter!

I once had a problem when I installed my Blizzard 1230-IV and a scandoubler and it needed extra juice. It toasted my A1200 power supply and then blew an even more powerful A500 PSU.

Could there be a problem in the power brick as opposed to the motherboard? I know there's a 1-Amp fuse in there that's very sensitive but components could be at fault in there if the A600 isn't getting +5v or whatever.

Maybe you could try a converted 200W supply (or Wizard PowerBox/Goliath).

We should have a tutorial on how to repair Amigas now that many of them are two decades old.

Did you get around to contacting AmigaKit.com as they repair Amigas...

As for Retrogamer, I picked it up in WHSmith but wasn't too enthused. I think my main interest started with the Master System although I did love my Sinclair ZX Spectrum +2 128k and I was intrigued by the C=64 and it's cartridge capability.

Retrogamer looked a very confused publication, they should have sections for each decade so that the really basic machines don't bore the life out of the late 80's gamers.

No, the Dreamcast has a TOTAL of 16MB of memory.

Sega Dreamcast - 16MB
Sony Playstation 2 - 24MB
Nintendo Gamecube - 40MB
Microsoft X-Box - 64MB

Odd then that a CD32 with SX32-Pro can have up to 130MB of memory.

:-D :-D :-D

The Dreamcast definately didn't appear as technically inferior to the PS2 however. In situations where multi platform games were compared the Dreamcast often had smoother, more refined graphics (Ready 2 Rumble 2). Certainly, comparing the awesome Shenmue 2 on Dreamcast to Shenmue 2 on X-Box will prove that there isn't a significant difference in hardware and the Dreamcast's demise was down to the fact Sega (unlike Microsoft) could not afford to lose $300m a year `buying' the public. Something the Monopolies and Mergers Commission should have been told about. Sony and Microsoft, unlike Sega and Nintendo don't make a penny on their consoles and rely solely on software license revenues. They also report the success of each game division on how many millions of dollars less they lost this year to last.

Dreamcast had the advantage of a visual memory card, something Sony tried to copy with the Pocketstation for the PSone. There's a lot of underground programming going on for the Dreamcast with ports of NetBSD, Linux and emulators for all the old consoles/handhelds. It's become a bit of a rebel machine like the Amiga!
