Fixed a minor multi-legged creature in the XGA sync generation - it would only have affected a few monitors, but hey, a bug is a bug, and needs squashing.

I also fixed a bug in the palette demo for XGA. You can always find my latest drivers on the Downloads page.

I managed to shave seven instructions from the plot pixel routine, so I updated the VGA/SVGA/XGA drivers and the Life demo.

As usual, you can find the new drivers on the downloads page

I’ve finally found the time to add three new product pages:

• Proteus - a high quality prototyping board, can stack on Morpheus or Propteus
• Propteus - a high quality Parallax propeller prototyping board, can stack on Morpheus
• SOJ36DIP32 - memory adapters, allows using fast SOJ36 package SRAM’s in DIP32 sockets

I have also uploaded the BOM (Parts list) for Propteus on the Downloads page. Enjoy!

I’ve updated all three drivers (VGA, SVGA and XGA) as well as the Life demo - you can find the new versions on the Downloads page.

The update is only needed for people who are running Morpheus with a Mem+ board, and was needed to allow for longer switching times between READ and WRITE and ALE commands in plotpixel.

I have also found that I had some 74HC139 chips that were not fast enough for Morpheus - if you see a vertical bar about 1/4 to 1/3rd of the way across the screen you likely need a new, faster, 74HC139.

If you purchased a full kit from me and have an affected part (series P9712AH, MM74HC139N or MC74HC139N) that exhibits this problem, please send me an email and I will send you an STMicro 74HC139 which does not exhibit this issue.

I’ve updated my XGA driver and Demo1 with the Palette handling code!

Now all three drivers (VGA, SVGA, XGA) have the same palette handling code and demo.

On the downloads page, as usual. Enjoy!
