Re: New release of EightyOne available

I am really loving the Jupiter Ace support in EightyOne, which helps me develop software for the Ace (and modern-day Minstrel 4th). The Minstrel 4th is fully compatible with the Jupiter Ace but has some modest extensions -- most notably extra ROM space. The Minstrel 4th accepts a 16kB ROM and, as we...

Re: New release of EightyOne available

Thanks for all of the updates to the debugger in EightyOne. This helps a lot with writing code. I have a (possibly foolish) question. I'm using memory view to see what changes when I do something at the ZX80 prompt. The viewer colours Red any memory cell that has changed, so you can easily spot that...

Re: New release of EightyOne available

I have realized that the problem only arise when when the option "Continuous" in "Control Window" is checked: Ah, ok. Thanks, I can reproduce the problem now. I see the the same issue applies to the Step Out button. I will look to include a fix in the next release. Hi, Thanks for investigating this...

Re: New release of EightyOne available

Anyone used the debugger in EightyOne to set breakpoints on I/O operations? I'm trying to detect OUT instructions to port FD (within the Jupiter Ace emulator) and have set up a breakpoint to trip when "OUT A7-0" = $FD. As I have to set a condition on the value, I set this to be >= $00. However, even...

Re: New release of EightyOne available

I've been making good use of the built-in debugger in latest version of EightyOne (V 1.29). It is really useful (as is the profiler) but I do see an issue when single-stepping throuhg a program. Specifically, I assume the Over button, when used on a CALL command, runs the called code and then resume...

Advice on Jupiter Ace development environment

Hi everyone, First of all, I realise this is a Sinclair forum and I am asking about a Jupiter Ace. However, I've not been able to find a dedicated Ace discussion group, plus I see there are some Ace-related discussions on this forum. I've been getting to grips with AceFORTH recently, using the Eight...
