Well done, sir! =D> I remember the feeling BITD when I did it with the original release. It was the first hack I ever made. It took me two days of patiently following the labyrinthine machine code to work out that a piece of code placed values on the stack to re-direct subroutine returns and that da...

Welcome, Peter.

Welcome, Zuffle.

Welcome, Dave. Enjoy your stay.

Welcome, Erik. The A5000 is a great machine.

At our secondary school, we had just the one proper computers teacher and he handled all the maintenance himself. I'm sure I recall other guys coming in to help installations but by and large, there was only the odd terminal PC opened up for repair and plenty of tinkering around on the server side....

This thread is from 5 years ago!

Ha ha! If I could read I'd be OK.

That looks the business. So simple!

No.

"IT and computers are boring! Can we go on the internet, sir?" That was a common litany three years ago when I was still teaching in secondary schools. Computers at home can do so much more than computers in schools. School computers are frequently out of date so that they cannot run the latest soft...

Well done, Marcus.

Games? The sign of a misspent youth!

Along with what MartinB says, BITD I had some of these transistors crack the soldered joints under the PCB. Reflowing the solder solved the problem then.

Beebug also did an article about this, somewhere.

A whole bunch of electronic goodness.

I bought this to go with my Raspberry Pi stuff. It also included an Arduino clone and a digital clock/thermometer, which were a complete surprise.

Looks good stuff. I need more colours too. For prototyping I now use what I think used to be called Vero-wire. It has a fusible varnish that acts like a flux so that it can be soldered without stripping. Cool. 8) Only have two shades of orange though. :( Do you have a link to that, as I can only fi...

Some of these for my Plotmate A4 IMAG1293.jpg They work a treat! :D =D> IMAG1292.jpg Mind you they are pretty expensive as they have to be specially made since they are no longer a stock item. I chose black ones but they can be ordered in red, green, blue, etc. to match the BBC micro's colour set. A...

Took me 10 or 12 manual iterations in a spreadsheet to do the turnstile problem. I'd like to think a younger version of me could do it in his head. But is there a way to do it without iterating? A spreadsheet is the best way to solve the problem. Mathematically the difficulty is that three simultan...

Ah, so it would seem to a mathematical programmer! :lol: Socially, what happens in this exercise is: split a class into 3 groups (say 10 per group). a group splits into two smaller groups, one subgroup is the presenters, the other the receivers Each presenter sub-group gets a problem in a sealed env...

Welcome, Chris.

I second that - from experience. I have an old Farnell 0-30v, 0-2A variable PSU which is similar to the Thandar one.

Good enough for a Beeb then?

Ah but the cheap one has no leads or PSU. They must be expensive!

Not at the moment - just a BASIC program.

I'd like to get it working with LOGO but that would need a ROM.

Not exactly software this but I have found a cheapish way to fit a pen to the plotter. The original pens, type 1CY14P5-N, for black, are very expensive and, as far as I can tell, are only available from a single company worldwide. The pens have to be made to order, which means expense and a long lea...

This sounds excellent - I think.

BITD I thought I understood electronics but now everyone talks way above my head.

The mags might be online but there is no substitute for holding a paper copy in ones hand, I feel.

Welcome, Robin.

Welcome.

Thanks for the A3 image links guys.

Unfortunately the A3 one will not drive the A4 plotter properly.
