I did the following experiment and concluded that ESC-Z and ESC-Y now work: 1. Typed ESC-Z on xcbm2 default config (that would be a 610 or B-128). The screen turned completely green. This is consistent with a missing but enabled alternate charset. 2. I doubled characters.901237-01.bin by concatenating it with itself and used the resulting 8K file as charset. ESC-Z now didn't show any change. 3. I edited the file from 2 to mangle the first few characters in the second (added) half. Now ESC-Z shows the mangled characters. It also tells me that it starts with the lower case set. In all cases, ESC-Y switched back to normal (in case 2 of course nothing was to be seen). So I guess this works now, nice! > Regards, > Michau. Cheers, -Olaf. -- ___ Olaf 'Rhialto' Seibert <rhialto/at/falu.nl> \X/ There is no AI. There is just someone else's work. --I. Rose
