Re: A3020 has died or did I broke smth?

A dead RTC shouldn't stop the machine booting. Just power-on with DEL. Then at least you could waggle the mouse about or try the bit of BASIC as above. If there's no response on either machine, that's when I'd guess something goofed with the mouse :( With no RTC it boots only to Supervisor mode, so...

Re: A3020 - no HD or floppy

You say you reset the CMOS and then replaced the battery, shouldn't that be the other way around?

Re: (HELP) RISC PC & the black screen of Doom... :-(

Just a few thoughts;
When you replaced the CMOS battery, did you reset/clear the CMOS? If not, I'd try that, and then reconfigure.
To check the HDD, right click on HardDisc4 and select Verify, see if you get any errors

Re: Femto Flash Floppy

You could just add a pair of 2 pin headers (or a single 4 pin) to the board. Then attach a couple of wires with momentary contact switches on them?
This would preserve real estate on the board and allow you to add the buttons as an option.

Re: RiscOS Hard disk formats

It sounds like a partial drive failure to me, I've had a similar fault on an SSD (In a PC) in the past, where I could only read from it.
Writes appeared to work, but when I went back and looked, all the changes had reverted.

Re: hi purchased an a3000 ide drive and need help

I can't see an IDEFSDiscs entry in the screenshot of the *Status output, so maybe that's part of the problem.
Edit: I'm not sure "Drive" needs to be set to 4 either, since IDEFSDrive is already set to 4.

Re: hi purchased an a3000 ide drive and need help

I'm not very familiar with these cards, but normally you need to configure the number of drives for each file system. I'm assuming the Watford Electronics file system is IDEFS, so you would need to specify the number of drives for it. This could be the 'IDE Discs' entry, which is set to 0, but I cou...

Re: hi purchased an a3000 ide drive and need help

Could you do a *status and post the results?

Also ensure that the drive select jumper on your CF adapter is set to Master.

Edit 2: Just looking at your photos, where is the CF adapter getting it's power from?

Bit confused, SCSI and IDE are two different standards and aren't interchangeable.
