IECHost update

Back on IECHost just briefly in order to add something that I thought would be useful: dumping the drive’s RAM/ROM contents.

Dumping RAM contents can help debugging drive code. Dumping ROM contents might not have much use, but it can help create an image of the DOS and e.g. compare it with ROMs available on the Web.

On something a bit more long term, I am still looking for a 2-bit protocol that I can leverage for quick disk dumping. I have the gut feeling that an asynchronous page transfer between IECHost and a 1541 without acknowledgements within the page itself could be possible and allow two-revolution track dumping.

Work stages of my HF logo for Border Mania

As I had captured some of the progress while working at the logo for my crack intro, Border Mania, I decided to share my work stages:

DC2N5-LC TAP playback tested!

This evening I managed to test the TAP playback feature of DC2N5-LC. I loaded the games I usually use for this sort of tests, including The Great Gianna Sisters and Bart Simpson VS The Space Mutants.

Here’s a picture of the playback test:

DC2N5-LC prototype first tape dump done!

The first DC2N5-LC prototype I am building was used to make a tape dump, which was successful!

DC2N5-LC build in progress

I managed to solder the micro SD Card socket and the ARM processor onto the DC2N5-LC board this evening. I tested access to an SD Card contents and that was successful:)

I will have to finish soldering a few bits and pieces, and connect the LCD. As the board is designed to be put into a specific enclosure, I will work on the carving side of things cutting holes here and there.

If it all works as it should, it will be a nice device to hold and use:)

DC2N5-LC boards arrived

Together with a cheap soldering station I finally received my DC2N5-LC boards today!

Unfortunately I had a long day at work and I am too tired to check out either one of these right now.

Border Mania

The latest of my crack intros for the Commodore 64 has been published on CSDb.

A video is available on YouTube as well:

This was a by-product that I put together while working at a different crack intro. It constitutes my first attempt at opening side borders on a Commodore 64.

I actually coded the scroller first (after a pretty long process of selecting adequate fonts and converting them), chose the tune, and worked out how many cycles I had left in order to open the side borders for a logo. At that point I thought to make the logo too:)

What I will be publishing here is about opening the side borders pragmatically using stable code so do watch this space for useful code and hints!:)
