Cheers for the heads up, Alex.

I'll have to compare like-for-like when I've got some spare time.

I don't know if this is of any use? The link was posted on EAB this week

Thanks for the reply, Dave. I don't know for certain that it's 1982. I'm deducing that from the name. The 77-68 appeared in 1977 and used a 6800. It sort of follows that the
82-02 would have been published in 1982, and it definitely used a 6802. All I have is a photocopy or print of page 5 (and I can't lay my hands on that right now).

I'm sure it came after the 77-68 and I've looked at page 5 of all the more recent available ACC newsletters without finding it.

Best regards,

John,
Might not be 1982. Might be an 82-pin bus.  Anything else on the page?

Hi All,

Just retired and excavating the spare room, I found one page (photocopy) of an article from the ACC Newsletter about the 82-02, a very simple 6802 machine
from (presumably) 1982. I have the circuit diagram and a bit of the text, but I'd like to have the whole article.

Does the museum have copies of the ACC Newsletter from that era? If so I'm guessing that photocopying isn't permitted and the present Covid situation makes the
originals inaccessible for now. No great hurry, but if anyone can point me in the direction of an archive I'd be grateful.

Best regards,

John

Yes Mike you're right, with the overhead light all scans of glossy magazine paper had a big white spot in the middle. Unfortunately, with the backlight, the bottom of the page would often look darker than the rest as the software tried to be too clever and the contrast threshold makes it look worse.
Another problem was that the lasers try and guess the shape of the paper and distorts the picture it's sees to match. While that seems to work quite well on smaller books with paper that keeps an even shape, on magazines with curly edges, all that seems to go out the window and frequently tried to compensate for curves that are not there. Having to regularly manually edit the laser lines and the centre line was a pain. It seems to be worse when there is more black ink on the page.
On my Google Drive, there is now a folder called 'Scanned with overhead scanner' I have included the results of several hours of fiddling with the overhead scanner per magazine to make them look as good as possible, you can compare the scan of ‘Using your BBC Micro’ with the one I did with my flatbed scanner. Then you'll see why I decided to stick to the flat bed scanner. Pity, the overhead scanner is an absolutely gorgeous bit of kit and when or if I have scan a book, it would be the perfect tool for the job.

Did you try using the backlight as that seemed to work better with the few colour tests that I did?
