Re: Centronics printer to usb converter

I am sure there are lot of people around who dont actually print much any more but given the ability to use modern printers on a Beeb, would happily get something like this just because it exists. And who doesnt have about a dozen RPis kciking about, I am sure they breed. And I get to add something ...

Re: B-Em

That scrolling demo seems to be missing NuLA. Is it the NuLA version? I first saw this as a NuLA demo but I have since discovered there is a version on the B-Em demo disc that came with version 2.2 and is still in the discs directory which does not attempt to make use of NuLA. Interestingly the NuL...

Re: Which Emulator for BBC Micro on Linux?

Interesting - thanks for this! I'll try it out when I'm doing my Linux fixes. I'm not surprised if it is rather slow on a Raspberry Pi, since b2 is written with a modern Intel system in mind (GPU, good branch prediction, lots of MHz, out-of-order execution) - which is another way of saying it isn't...

Re: How t pass arrays into procedures?

I waste loads of space making the program readable, then run it through a basic code cruncher. Best of both worlds then. Readable, maintainable but still small.
