Welcome, Knuckx. Someone else from sunny Derbyshire.

These Commodore calculators look to be very good. Simple but with everything one would need. I like the green display. :) That Thornton slide rule is almost identical to mine. I bought mine when I went into the sixth form. BITD it was the bees knees and cost an 'arm and a leg'. It lasted me all thro...

Nice.

I usually use a solder sucker to desolder stuff but I do have a 'proper' de-soldering station similar to yours. I've only needed to use it twice but when I did it was indispensable. They are a great tool.

The instructions downloaded from Boobip.com are great, completely explicit and designed for newbies (he says from practical experience :wink: ) The only real thing to watch out for is that the pins on the carrier boards are aligned properly before pushing home the boards into the sockets. The pins d...

The ability to search for titles in an age range has been added. This is a beta version. Please let me know if there are any issues (there may be 'features' though )

Boobip.com.

Hah! With one question you have highlighted a gap in the searching algorithms for my archive! :( I'll see if I can fix that today. In the meantime you could try some of these; Micro Primer Mr T`s Alphabet Games Mr T`s Measuring Games Mr T`s Money Box Mr T Tells the Time Mr T`s Shape Games First Step...

That looks a nice Beeb. Well done. I can echo Tricky about the Boobip SWR stuff - it is excellent and extremely versatile. I went the whole hog and fitted two EEPROMs and two RAMs so that I can have all 16 ROMs populated if I want. That is almost certainly overkill but I use the Beeb for archiving w...

I like demontart. Yummy!

If it is misbehaving, and you're confident all the connections are good, the card is properly set up, and there's no faults with the hardware itself, it's possible that it's the user VIA (one of the two 6522s) that's not working. Yep, I'd second that. I have had that problem - it is really annoying...

Welcome, Phil. :D The mono output from the A3000 should work via the video (yellow) RCA input on a modern TV. It should work OK, not like an analogue TV signal. First thing to do is remove the battery and clean any mess and check if any circuit tracks have corroded away. Next you could try to do a P...

That's a straight forward looking calculator and well used loved.

You were lucky in the 90s - you had calculators. When I did my exams 'when I were a lad' we had to use 4-figure maths tables for sines, cosines, tangents and calculation using logarithms.

I found a book of 7-figure tables in WH Smiths and thought I was in heaven.

I love the smell of magic smoke in the morning.

Welcome, Angus.

Welcome, Dave.

AQA advice for GCSE?

That was A-Level stuff when I taught maths, matrix arithmetic and complex number arithmetic especially. Looks like a case for the HP-15C.

Welcome, Tim. :D For 3.5" floppy drives Omniflop is the way to go. A Raspberry Pi inside a working BBC micro? As a second processor or as a storage device, great idea but don't mess with the Beeb. :evil: A GOTEK drive as the second drive in that Watford Dual drive case would be an excellent way to g...

I definitely agree regarding the Sinclair Scientific. BITD my slide rule was faster and more accurate than that. It was, however, cool and very small. 8) Commodore calculators I never used. They were available and that SR4148 looks to be ergonomic to use - I might try to find one. :wink: I liked the...

The other day I had a constructional problem that needed me to calculate tan(30°) x 1.2. I went to get my trusty calculator to do the calculation and that set me thinking. 1. Which of my scientific calculators would be the best to use? 2. Which of these calculators would be best for GCSE use in scho...

Welcome, Ron.

Shame about having to give up the BBCs.

Welcome, Cameron.

Am I missing something here or what?

That is a brilliant acquisition of the RISCPC setup.

The two ways I used to solve this problem were; 1. I used a parallel port Iomega 100Mb Zip drive with RISCOS 3.11 formatted 100Mb Zip discs. OK I have one but they can be picked up very cheaply. (The drivers are on my website in the RISCOS section). This is a fairly quick method and good for backing...

Welcome, roobarb.

Good luck with your repairs.

Place an END between

UNTIL FALSE


END : REM needed here to stop the program running through the PROCs unless they are called.

REM ...

Welcome, Mark. :D That is quite a history you have there. BITD I was one of the enemy stopping 'liitle oiks' like you doing what you did. :lol: Luckily I was a lot better and craftier than my students and managed to lock down the computers pretty well on our network! It didn't stop them trying though.

Welcome, dhester.

Keep me posted, always enjoy going through another ROM collection

Attached is a list of the ROMs I have found so far. The aim is to package these on SSD images so that they are easy to access for anyone who wants them.

This self-isolation I find is a time for catching up with things I have been putting off doing. Yesterday, for example, I catalogued my BBC ROM collection. The impetus was that I have the documentation for the Continuous Processing ROM for Wordwise Plus but this did not come with the ROM. (I found t...
