Not a lot to update on right now, as I've had limited time once again due to lots of assembly service work to get done.
However, in the last couple of days I had a chance to update the demo software seen previously in regards to setting the correct
palettes for the pictures, so a bit of software dev, proving out the hardware.
Here are some photos taken today that show the pictures with the correct palettes set, and obviously a lot clearer pics as a result.
The photos were taken at Springers Leisure centre in Keysborough today at the 'Vintage' section of the computer swap meet.
Additionally, I've started work on updates to the FPGA / Dragonball So-Dimm.
There were a number of fixups I needed to do to this board, but I also wanted to make a some changes which are :
A) replace the 2Mbyte SRAM with a 48LC16M16 SDRAM which is cheaper and is 32Mbytes
B) add a 1Mbyte parallel flash rom to boot from rather than rely on getting code out of the SPI flash which is used for the FPGA configuration
C) once I've tested it, I want to add the HDMI & I2S sound parts.
So, lots of PCB routing going on :
It's a 6 layer board (1mm thick) routed with 0.125mm signal tracks, and it's very tight.
More updates in the next week.
