Hi thanks for liking #Xts-uBasic, & wish Your CHIP8 project will work as you want... I really like Chip8 & made a couple of emulators in the past => if you can SCHIP8 & play Joust <= tilt me ;)

  Are you sure? yes | no

matseng wrote 01/18/2017 at 11:35 • point

thanks.... This is not my first venture into  Chip8- erritory. 3-4 years ago I made a small handheld device with a PIC24 and a Nokia LCD that had all of the usual games stored in an externalflash chip. It worked pretty well. I did a revision 2 of it with capacitive touch buttons and as I remember a different MCU...  http://dangerousprototypes.com/forum/viewtopic.php?f=56&t=6018

Thanks for following my Seven-Segment Sudoku. 
PS: When I saw your Earth Lander 84, I thought you've made a Sudoku also! lol

Hi Matseng, thanks for the invitation for your Relay Based Projects, and for the skull for my relay CPU !

  Are you sure? yes | no

Ted Yapo wrote 05/15/2016 at 01:20 • point

Thank you for the skull & follow on the Diode Clock!  I'm going to check out your Discrete Computer - I see you also have the "discrete bug" :-)

  Are you sure? yes | no
