Raven. A homemade Atari-like computer

Yeah sorry I should get rid of that topmost unnumbered changes descriptions — now that you mention it I realize it probably doesn’t belong in that file.

I kept track of work in progress stuff under the xxxxxxx description until being included (or not) in a proper numbered release.

So in this case, there is no new changes to firmware in the 250827 release package.

Another doubt concerns the Samtec SWT-122-01-F-D-RA component for building the byteswap adapter, because I only find the Samtec SQT-122-01-F-D-RA: is it the same thing? Thank you. You are doing a great job!

I double checked my order history and indeed, the part I ordered was SQT-122-01-F-D-RA and not SWT-.
Thank you! I have corrected that typo in the readme now

Can I ask you where you ordered from?

@luciodra , I got them from Mouser but I had enough other stuff in my "waiting to order" list to reach the point of free shipping.

I'm trying my 5420 but there are only a couple of resolutions that I can match. Now I have a nice 640x480x4 that I couldn't use before. The other resolutions don't even fiddle with VMG but nothing...

[agranlund]

@luciodra , I wonder if my code is failing to detect the GD5420 variant.
That card doesn't support linear access to the full framebuffer, but the driver is meant to support larger-than-vga resolutions by help of automatic bank switching.

Would be interesting to see what the serial logging says when you use the attached debug build (goes in c:/nova/default/auto)

@agranlund, we have placed your attachments in-line so they display correctly in your post. Here's the how-to guide.

A little better but...first the screen remained black, now white and then a ghost screen.
Ah,the 640x480x4 screen no longer works. No, after a minute of black screen, a color screen opens.

[agranlund]

Yeah it wasn't intending to fix anything. I wast mostly, or rather only, interested in seeing what it printed to the serial output.

Are we still able to use the SMT EPROM Simms? Iight make up one if so.
