DIGITAL PRESERVATION / Re: My magazines (almost all in PDF format)
« on: June 01, 2020, 12:09:09 AM »
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.

I've started the long boring process of scanning magazines that can not be found on the internet. As an Acorn fan-boy, I'm concentrating for now on BBC Micro magazines that are not currently available on 'The BBC and Master Computer Public Domain Library' - 8bit Software

I'm in contact with the site owner and he's agreed that he will thank 'David from the Retro Computer Museum' for the scans that he posts on the site.
They will slowly be added to my Google Drive

I tried using the fancy overhead book scanner that Mike donated but the results were not great when used on colour magazines (sorry Mike). So I'm sticking to a flatbed scanner which unfortunately takes about 1 hour 45 mins per magazine. My ambition is to scan one magazine a day, we'll see how long that lasts, but I've only done 5 so far with at least 80 magazines left and I'm getting bored of the job already.

Would love to, I know from memory that we have at least a couple of issues of A&B Computing

I'm not sure how much of a completist you want to be with your collection Mike but I found a few more Acorn publications (eg Disk User magazine and The Beebon magazine) for you to download if you want here

I'm loving what you've done so far Mike, keep up the good work.
I was looking forward to the playing with the book scanner you donated to the museum, I'd only just about finished getting the museum's magazines collection in the right order and in labled boxes when we went into lock down.
If I manage to find and scan any missing magazines I'll keep you updated. However, my next job was going to be documenting what magazines we had, that's going to take a little while, longer now I can't even go and look at them.

GAMING EVENTS - OPEN DAYS 2020 / Re: Minor Nascom gathering - 29th Feb 2020
« on: February 03, 2020, 10:19:18 AM »
I'm a volunteer at the Retro Computer Museum that will be there on the 29th, I am also the curator of the magazine collection.  I'm sorry to report that we currently do not have any Nascom magazines in our collection. I have a very cheeky request to all the members of the Nascom community that will be coming to visit us on the 29th. If anybody was feeling particularly generous and wanted to donate some to us knowing they would be on permanent display to the public and would allow us to represent another British computer manufacturer that risks been forgotten, that would be absolutely brilliant.

Ok done. I've cancelled my regular donation with MyDonate and setup an equivalent on Virgin Money Giving.

Just read the amazing story, I've never seen a repair log that has taken that many years to complete.

Hello Karl,

Welcome to the Museum forum.  That reminds me that we need to dig out the museum's old Dos games box, I don't think it's been out on display since we moved to the bigger building in January. it's somewhere in storage but no-one is sure where it was buried during the move.

You may have some problems getting your 386 on a modern network. Did you know that Windows for Workgroups 3.11 (WfW 3.11) did not ship with the TCP/IP network protocol that is used on the internet and modern networks?  It used the older NetBEUI network protocol which I always associated with the old 10base2 coaxial cables into a then ubiquitous NE2000 network card....  Sorry, showing my age now.  TCP/IP was released in 1993 which is the same year as WfW 3.11. The good news is that there is a TCP/IP stack upgrade out there for WfW 3.11 that I have used in the past that does the trick, but it's been over 20 years since I last used it.  Good luck and please let us know how you get on.

Hi Graham,

Welcome to the forum and congratulations to your son.  Hope to meet you soon at the RCM, I'm there most Sundays.
I can empathise about having a son who's now better at programming - my Computer Science degree is 25 years old and I ended up fixing them for a living instead of programming them. My eldest son is in his third year of a Computer Science with Games Development degree. What makes me feel old is the fact that the only programming language that James has been taught that was around when I was in Uni is C++, and at the time my Lecturers refused to teach it to us because they did not approve of Object Orientated Programming Languages saying they would never take off because it was a wasteful way of programming.

Any decision on November's film?  If you haven't picked one yet, how about the next installment in the Three Flavours Cornetto trilogy - Hot Fuzz?

Diane and I will be there.
