Re: Smonson's untitled simple harddisk project

Over the week I did a bunch of debugging and now my SD-card code seems pretty solid. So now reads and writes all work fine and never fail (so far). I can format the drive with AHDI and partition it into 4x 32MB partitions, which I can write files on. That's great progress. I'm not sure how AHDI is g...

You sure its just not a bad solder joint on the sram ?
I'm not sure of anything! But even if it is, after passing through the FPGA and then the bus driver (which has Schmitt triggers), as I understand it should be back to a clean signal again.

Re: Sidequest: VGA scan doubler

Yesterday I hooked up the blank connection, but it didn't solve the remaining issue. The issue is that when the screen has a dark background, such as black, it's got an interesting pattern of distortion on it: a gradient of brightness which alternates in intensity and also gets brighter towards the ...

Re: Sidequest: VGA scan doubler

Thats what i have currently, OSSC outputting to monitor. It does work really well in medium resolution, but haven't been able to get high resolution out of it yet. Don't get the option to enable it when in GEM. Is there a way to get the high resolution mode out of the Atari with the OSSC? although ...

Re: Sidequest: VGA scan doubler

I didn't measured precisely but on my STE the resistor ladder and the mono output resistor look like they are neatly arranged in a 4x13 0.1" matrix under the power supply. Maybe they can be replaced by a header and put on a daughter board along with the scandoubler circuitry :idea: But anyway I too...

Re: Sidequest: VGA scan doubler

You can also use an external scandoubler like the OSSC on an STE (if you can get your hands on one), which gives amazing results according to what I've heard. It works basically the same way except that it's not timed to the Atari's internal clock, and it has to pass the signal through an extra anal...

Re: Sidequest: VGA scan doubler

Just out of curiosity, and please excuse my ignorance, i have an STE, but have no idea where this would sit? Will it work in an STE? Unfortunately, there are a couple of snags getting in the way of that: There's no easy way to plug something like this into a socket, each wire would have to be indiv...

Re: Sidequest: VGA scan doubler

You can see some muddiness in the black when there's a black background - that's probably just a result of me not having added the wire for BLANK to my ST yet.

Re: New guy from PL

Awesome. We have lots of hardware projects going on around here, but not enough software projects! I'm also a programmer myself.

Welcome to the forum - I'm looking forward to seeing what you come up with!
