Workprint – June 2017

June 13th, 2017 by Jason

There hasn’t been a lot of coding time for one reason or another recently, but one thing I’ve been tinkering with a little is the SuperCPU or more accurately an emulated version courtesy of VICE; I’ve reworked my unrolled plotter – the one used in MD201704 – to handle about four hundred points. There’s also a “user interface” so that the cosine curves can be fiddled with as well because that seemed like a fun thing to do.

Halfway through playing with it I realised that, since it’s 6502 code rather than 65816, there’s no reason it won’t work on my Turbo Chameleon-equipped machine as well… where the 6MHz mode takes longer to get all of those points cleared, updated and drawn whilst the “unlimited” mode actually gets job done faster than the SuperCPU! Since I can at least release it as tested on one real accelerator and possibly get someone to run it on a SuperCPU as well, this may well become MD201706 and there should be enough raster time to finally use Sean’s double speed cover of Brian The Lion without breaking a virtual sweat.

There’s also a C64CD demo being prodded at right now, quite literally in fact since it’s testing on my C64C as I write. Unlike previous releases on said label it isn’t inspired by classic 1980s or 1990s releases and instead has a loose theme based on current events and a discussion at the Atari Age forums which got onto the subject of encryption. It needs a little more work, but should be ready to go either tomorrow or possibly Thursday.

MD201705 (C64)

There’s no theme to MD201705 so I can’t mumble about that for this post, but it does rework an effect I did previously in the demo Mish Mash, covering a larger area of the screen and updating the colour RAM this time as well as adding some more cosine curves for good measure.

It’s available to download from the usual suspects and the source code is available from Github too. There’s no YouTube video at the time of writing but I’m in the process of rethinking how to do those for better results.

Here comes the groom

So about now I should be stood in a registry office in Leeds, wearing a suit of all things (yes me, wearing a suit… I don’t know how that happened either) and getting married. But through the power of WordPress automation, here I am posting about it at the same time, partly because there’s a couple of hours to go and I need something to occupy me so that the contents of my bag don’t get checked for a fourteenth time.

I was hoping to find time for finishing and releasing MD201705 yesterday but things didn’t entirely go to plan and most of the day was spent fretting with a pause around the middle where we went into town for the cake!

I probably should point out that I’m not worried about actually being married, Sue is my soul mate and we’ve been together for sixteen years so there’s no doubts in my mind on that front; I’m just not best keen on the whole getting married part of the deal, being somewhere close to the centre of attention. But I’ll deal with it and thanks to everyone who wished us both luck, especially the ones who got the abridged version of this post in response – sorry about that! I’d better go now, I need to get that bloody suit on and there’s bag check fourteen to do as well…
