Re: 6502 Assembler

I use beebasm for all my stuff.
There is a github and some people here contribute .
I have hacked beebem to load the labels that can be exported so as to show them when debugging.
There is also swift, by I have not tried it.

Re: Need help with BBC just picked up please

Do you have any interest in building one of the cheap logic analysers from hoglets thread?
You can connect it to the tube and he has a program that will turn the capture into 6502, which can then be compared to a known good trace to further aid diagnosis.

Re: Need help with BBC just picked up please

It seems that most parts of the machine work, including display, sound, at least partial OS reading and RAM. I can't remember if you can put eproms in sideways slot 0, but if you could, you could put one of my games (probably not space invaders) in there and it should auto boot. You just load the ma...

Re: Need help with BBC just picked up please

Someone in another thread suggested reversing the cable as a quick check to see if the symptoms change. I mention this for others as you have already done a more thorough test.

Re: Need help with BBC just picked up please

The screen shots from my test ROM look OK.
A good way to check is to run the same test in an emulator side by side.
I can't remember how to change the emulator OS, but you can temporarily rename the files.

Re: Acorn Atom & BBC Master System

Welcome, I'm no hardware expert, but the CUB should be fairly easy to fix, only problem is that there aren't many CRT repairers around, although we do get one or two at the ABUG meetups.

Re: New version of Scramble for the beeb (going well)

Here is a version to "hide" the VLSI corruption, as I don't have a VLSI 6845, I can't be sure it will do the job!

PS It should be OK on anything except BeebEm, but I haven't tested it yet (haven't unpacked from ABUG yet!).

I thought that part of the reason for alternative DFSs was a shortage of 8271 chips. I member double density controllers early on with their own DDFSs.

@Tricky - is the corruption at the bottom of scramble on the agenda for the weekend? Would be great to get that sorted :D
I forgot to take the scramble source and to be honest, until I was talking about it on Sunday, I had forgotten about it. It is a simple fix, I just keep forgetting to do it!

My atom lives with ramrom and mmc. Flappy birds crashes if you make it through the first obstacle. There were a couple of games that were crashing: tetris and w.a.r. but they were fixed by an mmc rom update.
