!Browse CD

Hi all,
Does anyone have a working link to the Acorn !Browse CD? I've just got my ethernet card working on my A5000 and I'm looking for the RO3 Omniclient install files from that CD and other internet software to get full use out of it

TIA

Re: Cleaning-up an A420 keyboard

Nice work! I broke one of the plastic retainer clips (and lost it :x ) while cleaning my holder, they're very fragile. I'd like to know if anyone has a good way of repairing the damage

Welcome Richard!

Looks good to go to me. Just remember to clear the BIOS (hold down Del key on power on) and fingers crossed it goes right to Desktop

In that case, to both Paul's!

Yeah I kind of regretted not using my hot air station considering I'm more comfortable doing this sort of job with it. I will return to it when I get time and tidy the work up at the very least. Need to replace the PSU fan in it too it's pretty loud

(Yet another) A5000 restoration

I picked up an A5000 setup yesterday which knowingly only booted to Supervisor. The battery had been removed and apparently cleaned but other than that it was a truly unknown quantity. The person who I picked it up from did all the usual methods of trying to clear the CMOS so I guessed that this was...

Electron key switch

Is this just a simple case of replacing the key switch? Does the replacement just slot in or do I need to solder it and / or remove the pins??

I'm not familiar with Electron keyboards (or in fact Elk's themselves)

Thank you very much for the prompt reply. I haven't try formatting on the A3020 so that will be the first thing when I get home.

Apart from the dubious legality here, is it as simple as burning the rom images found online with many a popular emulator to four new 27c eproms and just dropping them in? All I ...

Sorry I know this thread is a couple of months old now but did you or anyone else try vinyl dye?

I have a Micro ready for retrobriting but I'm leaning towards dyeing it instead as it's more permanent / even but unsure of the colour needed (white, bone etc)

Re: A3000 post-battery repair

There is a lot of corrosion in the mouse port that no amount of lemon juice or IPA can flush. I think I might as well replace it, just to confirm it's just a standard 9-pin mini-DIN and these will be a suitable replacement? https://www.ebay.co.uk/itm/Computer-Part-Din-9-Pin-Female-S-video-Adapter-So...

Can you change a configuration option and does it stick after a reset / ctrl-break? E.g. *config. baud 4 You can use *status to check.
