Hi
No problems.
Send me a PM when you are home and ready for me to post it.

Yes, I might as well keep everything together. I expect the motor will make a good output device for indications.

Give it a few days while I get myself home and settled again.

Re: Down-sizing because of retiring. Everything has to go.

I weighed it all today and it is just under 2Kgs, so £15 UK Pounds to ship.
Hope this helps?
Regards
Andy

Hi
£15 UK Pounds if the parcel is under 2Kgs.
£20 to £23 if over 2Kgs.
Both will be insured for £50 and signature required upon delivery.

Just to double check you want the stepper motor ...

Sounds quite reasonable, though I probably won't be able to use the ...

Re: Down-sizing because of retiring. Everything has to go.

Yes, Yorkshire is definitely a bit too far from London for a drop-off! ;-)

I appreciate the main board needs some attention. The sockets need cleaning & the reset circuit is a bit temperamental. And the NVRAM is quite old.
So I've priced it accordingly.
£30 UKPounds for the main board and the ...

Re: Down-sizing because of retiring. Everything has to go.

Whereabouts are you in the UK?
I'm in London.
It may be possible for me to drop it off if you are not too far away.
Or maybe do guaranteed next day delivery.
Regards
Andy
PS: The NVRAM is still working okay.

Well, I'm back on the right continent at least. Actually I'm in the UK for a few days, but ...

Re: Down-sizing because of retiring. Everything has to go.

Hi Chromatix
I've added a photo of my SBC and all the bits that go with it.
To the right is the programming board for the battery backed RAM (being used as a ROM).
At the top is the stepper motor and driver board.
And then the SBC itself.
All sitting on my project report. Over 100 pages of ...

Re: Down-sizing because of retiring. Everything has to go.

Hi
It will be a good price! I know I have to down-size and I would like to go to someone who will use it.
Will you contact me when you are back in Finland?
Regards
Andy
I might possibly be interested in the SBC, as a way to help bootstrap my own efforts, but I'm away from home for the next couple ...

Re: Down-sizing because of retiring. Everything has to go.

Thanks Ed,
I've already registered for stardot (as someone else had already suggested it was a better place to advertise BBC Micro stuff).
BTW I have a few Beeb items on eBay. Including an Epson dot matrix printer - tested and working.

Re: Down-sizing because of retiring. Everything has to go.

I've added a close-up photo of the main ICs.
From left to right....
6502
RAM
ROM (battery backed RAM)
6522

Yes RAM DIL with integrated lithium battery. And still working after 25 years!

Ahh, so the SRAM is one of the RAM DIL modules with an internal integrated back-up lithium cell ...

Re: Down-sizing because of retiring. Everything has to go.

I haven't got the board in front of me but from my project report I wrote at the time, I used an NMOS 2MHz 6502
I think the 6522 is on the far right of the board. And the 6502 in the centre.

The battery backed RAM is actually an IC rather than a card. It's plugged in to the ZIF socket on the stand ...

Re: Down-sizing because of retiring. Everything has to go.

I've added a photo of my old Beeb with the programming board.
The programming board is for the 2KB battery backed RAM which I used as a 'ROM' in my stand-alone board.

I soldered ribbon cable to the motherboard and a ZIF socket the other end.
Can have either the programming board or the sideways RAM ...

Re: Down-sizing because of retiring. Everything has to go.

Hi Ed

Hopefully I've added a photo okay.
Photo shows the stand-alone 6502 board.
The battery backed RAM acts as a ROM having been previously programmed on the Beeb.
And the software running the stepper motor was downloaded from the Beeb on to the RAM on my stand-alone board. IE can develop software ...

Down-sizing because of retiring. Everything has to go.

Hi
I'm new to this group though not new to 6502.
I've been involved in computing since 1977, and wrote my first 6502 code in 1980.
But the time has come to retire (a bit earlier than planned due to ill health).
And I need to down-size which means finding a new home for my 6502 stuff.
I have had a ...
