Coming Back

Postby yellowpig » Thu Sep 14, 2017 7:14 am

A few days ago I thought I had discovered here a Beeb-related forum that I hadn't come across before. I turns out that I registered with stardot.org.uk in 2006, and then totally forgot about it for over ten years! A bit remiss of me really, as an enthusiastic Beeb user ever since I got my first machine in 1981 - with the original OS 0.1. I can only blame pressure of work, and I have hardly touched the Beeb over the last decade.

I have recently retired now, and can now take up some of my old interests again. We have also moved into a smaller house, though, and there is nowhere to set up the Beeb (I replaced the old one with a Master 512 some years ago, as those of you who know my website may guess) so it has unfortunately had to be relegated to the loft. (Well, I suppose I could put the PC away instead, but ...)

As a result, I am now exporing emulators, particularly BeebEm, mainly using Vn.4.03 because it supports the Master 512 co-pro. It is an excellent program, in my view, though I was a little disappointed to find that three of the programs I wrote specifically for the Master 512 do not appear to work with it. (I am not surprised about this - they all use some very low-level techniques that are likely to interfere with the way an emulator operates.) I wonder if I can modify them.

Welcome back to the Forum, David . . .

If your programs work on real hardware then it indicates that the emulator you are using either needs upgrading or tweaking. I'm sure someone who knows what they are talking about will be along shortly :D

Welcome back! I've found your site very useful on many occasion. You're probably not aware but MAME now supports the Master 512 as of the 0.189 release, no mouse yet though. Try your software on there and let me know of any issues.

Welcome back,
beebem is getting some love at the moment, so there is a chance that it can be made compatible.
b-em is good, as is jsbeeb, an in browser emulator, which is used when you launch a game from the Complete BBC games archive which you might have also missed as well as some of the games in the Year 2000 on section.

Thanks for the welcome.

If your programs work on real hardware then it indicates that the emulator you are using either needs upgrading or tweaking. I'm sure someone who knows what they are talking about will be along shortly

I am not sure about this, and I think I may need to sort things myself when I have time. The programs I am talking about are:

  • My Co-Processor Filing System (or CPFS) which uses the Tube "backwards", so I really cannot expect it to be emulated
  • A program I called PCCE (for PC Compatibility Enhancer) which extensively uses the Trap Flag and Unknown Opcode Exception - just the sort of thing that has to be used at low-level in an emulator, and the two uses are bound to interfere
  • My Master 512 Mouse Driver - the AMX emulation seems seems to work in quite a different way
I think I might be abe to get CPFS working, though I will have to look carefully at how the emulated Tube behaves when it is present but configured "Off". The other two are going to be harder.
