Some pictures i did during development of the cartridge...

See the ultraDev cartridge in action. Starting an round about 780kb file in 0,94 seconds. Means the data is transfered with around 830kb/s.



The ordered samples of the PCB:



The new rev.c prototype



The new revision c of the PCB is done. Looks like this.




The cartridge connected to a STE. Yeah my STE looks always like this doing alot hardware things with the STE currently.



After a reset the Atari shows this screen waiting for commands from the host computer.



That's the FPGA development board i use. TBH fully overpowered for this job but it's cheap around 30 Euro. Would be possible to do alot more with it than just a cartridge. For example implementing a open source 56000 dsp that would make the atari to a small small falcon. Just an idea but nothing i'm planning to do ;)



The first version of the cartridge which didn't work at all. Well forgot about the 5V the Atari is running and this roasted the FPGA unfornately.



Second version of the cartridge which worked. YAY!... You can see the small difference on the left the bus transceivers. As you can see some last minute changes are done anyway. The big chip is the ram for Bugaboo the smaller ic on the right is for usb communication which enables usb 2.0 full speed.



The tool to update the FPGA. I really love it ;)
