Thanks for you reply, VingtTrois!
Actually, I'm not confident enough to tamper with the hardware. I haven't used my A2000 since circa 1994. I'm not sure which ROM I've got, but I've got a couple of floppy disks named Workbench 1.2/Extras 1.2 if that might help determine which ROM I've got.
Like I mentioned earlier, my A2000 sounds "normal" during start up but if memory serves me, I think there should be a green light under the Power indicator on the far left of the computer. This green indicator doesn't illuminate. Could this indicate a Hard Disk failure?
I'm considering selling my A2000 as I don't have space or time enough to use it, but I just thought it would be a good idea to check the functionality before doing so. I have no idea on the amount of labour or costs that might required to make it work.
I can't find the scart connector (which I assume should be used to produce image). The only cable I found was the TTL.RGB connector with mono video/left audio/right audio inputs...
