Depends on the current draw for the fan and the power budget on the PSU. I assume there is a bit spare on the PSU even when it's all running flat out so as long as it's a low power fan there should be no problem at all.
Funny that Spy Hunter was mentioned. I actually made a bit of progress with that. I had a smooth scrolling multicolour bitmap road. I was working on making the "sprite" but as with all my VDC code, that is where I have paused
I might have another go at it so I can make a video for you showing the scrolling road and (stationary for now) cars.
Tokra did some great work getting a VGA compatible output from the VDC however he had to lower the horizontal resolution.
If we could push the 128 to even match the original 640 and output 31khz that would be amazing! It would then be possible to hack 80 col software to work native on VGA monitors with as little as a few resistors to connect to the 128 (minimum). I love seeing all this work pushing it to it's limits.
I would be exceedingly interested in any further work on using VGA monitors without scanrate conversion.
It's not atm. Been busy with work, trying to assemble video adapters and family life.
I need to sit down and spend a lot of time working out my software sprite code. I need to be able to shuffle bits around. The idea is to have a 4 character tile and be able to position it pixel by pixel in a 9 character "sprite"
