Re: RiscPC video output failure

Thanks guys, it’s all getting a wee bit clearer, I’ll bell out the connections tomorrow. Here is what I have just now. 80F06079-B2C4-4CC5-AFDD-CF230ACD107D.jpeg 39D7B532-DD70-4A6A-BE5C-22E55D443A6C.jpeg I thought I had got away with just the CMOS/RTC, but looks like there is more to find yet. Dave

Re: RiscPC video output failure

Hurrah! All credit to sirbod for the "high resistance" suggestion -- that's exactly what it was. Vcd<4> from RP16 to VIDC was 800K. A wire-strap later and the machine's alive and kicking and all well again. Amazing. ... with DRAM. But VRAM still has the weird lines issue. :( Hi there, I’m...

Re: A3000 single key not working

Success at last ...... Turned out to be a connection in the ribbon cable connector. Although it all rang out ok, the spring part inside the connector was pushed into its housing and not making contact with the ribbon 🎀.....I won’t be caught out by that old chestnut again.... :oops: Thanks Ian for yo...

Re: A3000 single key not working

I managed to wrangle the over flexible ribbon cable and rung out the two shift keys successfully.

So looks like I have more ringing out to do, or it may be IC4 or IC5 if I’m lucky.

Right Shift turned out to be 7 on Skt 6 and 8 on Skt 7.

Re: A3000 single key not working

Thanks Ian,

The salmon colour on the right shift key on skt.6 was throwing me off a bit....

I’ll test it out after dinner, but it looks like if the right shift is working, then the left should be too, so it looks like a track on the membrane.

Re: A3000 single key not working

Hi there, thanks for your response,

I found this link this morning it tells me it’s Pin 13 on skt6.....but what other connection do I need to test continuity, and see the membrane working or not.

Without a legend, I’m not sure what the colours mean.

Thanks Dave

Hi Soviet,

Nice job, do you have a drawing of the connections between the alt keyboard and smallymouse. ?

I was thinking of trying the same upgrade.

Not quite what you asked, but I can access the CF card from my A3010 in a USB card reader plugged into a Raspberry Pi running RiscOS 5 if you have access to one.
Thanks Andy I’ll dust off my pi and give it a go.

A5000 mouse replacement

Hi folks,
I’ve recently acquired an A5000, the mouse supplied is pretty much useless, very sticky, I’ve given it a good clean etc but to no avail.

The only option I can see is to buy a £30 adapter.

Are there any other option open to me as £30 seems a bit steep.

Thanks

Re: A5000 hard drive replacement

Thanks philpem,

I give it a try, my A5000 arrives today between 17:00 and 21:00, but the battery looks in a bad way, the photos are not clear but I’m sure I can see some fur on it, so I’m,looking out the vinegar and cotton buds.

Re: A5000 hard drive replacement

Yes I noticed the blank spaces, I’m just glad there is something on the other side.

There was a blurred picture of a screen showing the supervisor prompt and I thought it looked more like a 4 ....

Might be a project finding out if I can populate it.

Re: A5000 hard drive replacement

Hi

Thanks everyone, lots of food for thought.

I’ve sourced the parts but will wait till the A5000 arrives.

I can also get a 20 gig ide hard drive for £10 as another option if all else fails.

More fun to be had.
