How do you access the additional graphical characters in the dk'tronics rom for the zx81

Post by Crayon21 »

i'm curious. In addition to the regular character set, how do you access the new graphic set?

In the manual page 5, lists the USR command you need to change to that char set. The USR command is also listed on the char tables in the end of the manual.

I tried, it's not working. What am I doing wrong?

Do you have the hardware for your ZX81?

Or are you using an emulator, which emulates the dk'tronics ROM?

Under hardware settings try different settings under Interface tab:

Change field "Chr$ Gen", and see if there's an option for dk'tronics there.

If that doesn't work, then try combining it with setting or resetting 'Enable RAM in 8k-16K" under the "Advanced settings" tab:
