Re: Bush internet surf set

Networking I'm not terribly concerned about I was interested, because adding some form of networking is perhaps the easiest way to remove the ZIP drive dependency for loading software (well that, or something like parallel port based SCSI.) but VGA out would be nice... Given it's the RGB type of SC...

Re: Bush internet surf set

Well that sounds straightforward enough... does anyone have a ROM dump? I've looked about but can't find one. Otherwise I should be able to take a copy with a burner I have access to next week. It would be great to have the system booting risc OS without a zip drive! What else is on the wish list? T...

Re: Bush internet surf set

Physically, standard RISC OS ROMs will fit, but IIRC I didn't get anything out of my 3.7 ROMs. Partly, that could have been screen mode (I didn't try very hard, it must be said) but as flibble said the hardware is fairly different (eg., EEPROM rather than CMOS etc.,) Yes - I think that burning your...

Bush internet surf set

Latest aquisition (for the handsome price of £1) is one of these nifty little boxes. I've got a ZIP drive on the way, but I was wondering if anyone has tried sticking A7000 ROMs in one to see what happens, or knows of a reason why it wouldn't work? Would be great if you could boot RISC OS without ne...

Re: A3010 hard disc interface

1. Something is wrong with 16 bit mode but 8 bit mode works (unlikely?.. I don't think it has got to 16 bit mode yet, which is for bulk read/write). If you can get it to fully work only in plain 8-bit mode it would suffice, as the mini-podule IDE expansions we get for our Tens is actually 8-bit any...

Re: A3010 hard disc interface

So, I never bothered with CF on my A3020, mainly on the advice of APDL. I did try with my RiscPC and would get the card recognised then errors 21/22 or sometimes 8 when I actually tried to do something with it. Sometimes I'd manage to get it formatted, then it'd start playing up. Plopped in an SD/I...

Re: A3010 hard disc interface

Maybe I will buy an SD adapter, but I'm not convinced that is the issue. I don't really understand what is going wrong, because communication is clearly working in both directions as the CF cards all respond correctly to the identify command and send back their identity correctly. I have a couple of...

Re: A3010 hard disc interface

I've tried various from about 500MB to about 800MB, as well as the conner driver that came with the IDE mini-podule, which is about 20MB I think. That one gives error 22. I've no idea if any of the drives work, they've been in a box for years and have moved house with me several times... Aside from ...

Re: Tongue-tied A3010

Looking at the A3010 now, pin 6 is actually not easy to get to, except by plugging a wire into the mouse connector at the back of the machine. I'll have a look later and try to find an easier place to test from and get back to you.

Re: A3010 hard disc interface

I added the missing resistor and checked all the wiring, used a shorter IDE cable, and have scratched my head for a while. After thoroughly checking the schematics I've now figured out the problem - I misread a pin number on the schematic. I read 155 but it is actually 156, which means that I've sol...

Re: A3010 hard disc interface

Haha, ok I've just looked at the A4000 schematics and it has pin 27 connected to +5V via a 5K resistor!

I don't have time to fix this now but it looks like that is almost certainly the issue.

Re: Tongue-tied A3010

Well analogue electronics was never my thing, but I can see that the audio circuit certainly uses "Clean Vcc" a filtered version of the 5V line. It also needs the 12V supply and has dedicated grounds. I'm sure your 5V line is fine, but the only other clue I've got about where the problem could lie i...

Re: A3010 hard disc interface

It's a bit messy I'm afraid. The ribbon cables going to the CPU and the C&T IO chip are superglued to the PCB to stop movement. I guess I was feeling sadistic or something (stupid, probably) because in the end I didn't bother with kynar and just used the normal ribbon cables directly. I had a couple...

Re: Tongue-tied A3010

I had an idea with regards to this. My A3010 has a dodgy 5V line that will sometimes produce anywhere between 2.5 and 3.6V, other times it comes up as normal. I have to keep powering it on and off to get it to come up stable. When it has the wrong voltage, I get horrible noises coming from the speak...

Well I've finished soldering and the machine still boots, so I'm calling that a win!

I'm going to leave the software until tomorrow night but I will take some pictures to share before that when I'm putting it back together.

Re: A3010 makes a snoring sound

My A3010 makes a horrible, very loud, low pitched noise if the battery is low or not charged. And it then wont boot up for a while, I have to leave it plugged in for 5-10 mins with the power on then reset it. I've changed the battery now, but last time I powered it up it still did the same thing, I ...
