Useless Projects Vs. Useful Projects
This may be me, but i think build a project (with an MPU) that flashes LED's is pretty useless. My reason for believing so is that this can be accomplished with a 555 timer, or some chip from radio shack. You really don't learn much assembly.
Re: Bug??
Nevermind the first problem IRQ_vec is defined in min_mon, however it still wont assemble it will open the assemble screen up for like a second then go down nothing happens
Bug??
Kowalski wont assemble min_mon.asm. It Says I don't know what I should change IRQ_vec to
Code: Select all
ERROR E021: Undefined label 'IRQ_vec'. ROW 435, FILE C:\Users\James\Desktop\ehBASIC\basic.asm- Sun Oct 27, 2013 8:59 pm

Re: Getting young people into 6502
LOL: Lego, Arduino. You don't learn much from a prebuilt microcontroller using Python or C. I'm tired of people in my school calling themselves "hackers" because they know how to use command prompts and Linux. That's more noobish than me. Also since I have been with vintage computing, I noticed ...
