A3000 for sale

Post by oscarthecat »

Hi All,

Going through the junk room, I found my old A3000. Main board looks spotless, no leaks. Powers on. LEDs light and toggle with key presses and so it's probably working. I have a Philips analogue monitor to test it properly but I won't be able to get to that for a while.

1MB RAM upgrade. MIDI podule. Acorn Desktop Assembler (boxed with manuals). RISCOS Programmer's Reference Manual (boxed, 4 manuals).

Offers? I'm just trying to get an idea of whether it's worth the effort of collecting it all together, testing it and so on.

Thanks.

1MB is a bit tight for any great use IMO. Clean board (no battery rot) is quite rare. If it's in good nick physically, that's worth something though -- most of what I've seen go for anywhere in the range of £100-£400 on eBay recently has been horribly security marked, or filthy/physically abused. How's it doing for yellowing? Mouse included? PRMs are worth very little for their content, but some collector may find them physically amusing to put on a shelf. Ditto the assembler.

I just took the battery out. On inspection it looks like it was just beginning to go. Little bit of green and wet under it and a little bit on the nearby resistors. No obvious corrosion.

The 1MB is a 1MB upgrade, so 2MB in total. Original mouse.

Plastics yellowing is present, but not too bad. It's been in a drawer since I put it away 25+ years ago and so it's been stored in the dark. Case is intact and unmarked. Other than being slightly yellowed and a little dusty, it looks new.

Can I test the machine without the battery? Do I need to reset the CMOS or something?

Oops, misread. Ok, so that's a viable machine for games at least.

Yep, snip that battery out right away. It's fairly simple to pop in an 'AA' battery holder and NiMH battery (does require soldering - nominally with the board out of the case), but without any battery you can power-up the machine holding the DEL key until you get a beep, then it'll be fine until you power it off again.

Some pictures of the surrounding battery area would be useful to prospective buyers. The gunk has a habit of spreading far and wide though it sounds like in this case it's survived, even a minor clean up is usually in order.

The manuals usually go well on their own. You can use the mono connector to do a basic test to see if it outputs to a screen. With or without a battery, hold down "R" key and switch the power on to clear the CMOS. Hold it until you see the RISCOS splash

Values wildly though with minimal damage I'd suspect you'd get at least £150 for the basic unit, bit more with a mouse added (gunk can damage the mouse port and movement so well worth fully testing)

Perhaps a long shot request - would you entertain shipping it to me in the USA?

Is this machine still available? I'd be interested if it is.. especially if I could see some images of the inside near the battery area... I'm located in Reading UK...
