Removing Master Modem board

Hey all, My Master has a Master Modem installed which I would like to remove. The screws are easy but the white ribbon cable connecting it to the main motherboard is not budging and I don't want to break anything. Do I require any specific tools or am I doing it wrong? ;) Picture attached to illustr...

Re: Thrust Disassembly

I haven't forgotten about this but has turned out to be substantially more work than I thought. (Who is surprised? ;) Going through 9000+ lines of assembler and data has proven to be fairly time consuming plus I have a day job to do (it does make my train commute pass pretty quickly though.) I have ...

Re: Thrust Disassembly

Thanks Rich. You have a good eye - I found the keyboard reading routine last night and you're right it is still EQUB's. As the data blocks are interleaved through a lot of the code, I had to give BeebDis directives as to what to treat as data blocks rather than wade through a massive chunk of illega...

Re: Thrust Disassembly

Here they are - I did this back in 2003! :D My approach was not to comment the disassembly (for some reason). Instead I wrote a separate file of notes which explains key points of how the code works. I think I probably scribbled on a hard copy of the disassembly, and only wrote up some of my discov...

if I can find my notes, do you want them?
Yes, please! That would be very helpful.

Re: Thrust Disassembly

Yeah, given that Jeremy and Peter went on to create the most technically sophisticated game ever made for the BBC Micro, I'm assuming they were both ninja programmers and therefore this is a non-trivial endeavour..!

Thrust Disassembly

For reasons that I haven't quite determined (perhaps in small tribute to Jeremy C. Smith) I have decided to disassemble and document my favourite game, Thrust. I thought I would share with you all the first piece of that project. Attached should be a source file that is buildable using BeebAsm on th...

+1 on this. Doesn't seem like retrosoftware is ever coming back at the current rate. :? Does anyone have an ETA?

That's a shame. I couldn't make it in the end for various reasons. Does there exist a good general retro computing fair?

London Gaming Market - Sunday 15 November

Has anyone heard anything about this / planning to attend?

Seems to be an attempt to hold a regular (every 4 months) retro-game market in London.

Pasta - Smart assembler for 65(C)02

Hey all, Since retrosoftware is still down, I thought I'd ask here. Has anyone tried, or used in anger, the Pasta 6502 assembler as written by the awesome CRTC demo guys? Details can be found here: https://github.com/crtc-demos/pasta Until now I've been using RTW's fab beebasm but wondered if anyone...

Why is my '5' key not working?!

Now my Master is up & running it's developed an annoying fault - the '5' key has stopped working. Of course I can type '5' using the numeric keypad but getting a '%' out is a complete PITA! Any ideas what's going on here? Doesn't seem to be just sticking as I can't anything out of it, unlike my occa...

Re: Ripping ADFS disks

Thanks for the responses everyone. Alas I am a bit of a PC minimalist these days so only have tablets and an SSD laptop - no magnetic disks and barely any optical disks either! (Streaming is the future apparently ;)) I have managed to find a path by writing a simple BASIC program on the real Master ...

Re: Hello from Farnham

Thanks for the welcome everyone. Farnham, Surrey in answer to that question (is there any other? ;)) Sadly I no longer have an Acorn Electron as I flogged it back in the day to upgrade to a Master. As for the demos, it's just simple scrolly message sprite stuff at the moment (at least it's 50Hz flic...

Ripping ADFS disks

Hey all, I'm in the process of archiving my old floppy disks to PC via the TurboMMC setup on my Master. Being a Master guy back in the day it made perfect sense to use 640k ADFS L capacity disks. Of course these are a complete pain with an SSD based system. I've checked out the DataCentre and am on ...

Hello from Farnham

Hey everyone, I finally got around to registering after lurking for a while so thought I'd introduce myself. I grew up with an Acorn Electron, followed by a BBC Master and finally an Archimedes A3000 before I finally succumbed to the PC bandwagon at the end of the 90's. The Master is the machine tha...
