25. By John T Roecker 5141 Thomas Ave S Minneapolis MN 55410 Up to this point in this series of articles I have discussed getting WP 6502 running with a non standard monitor ROM In this third article I would like to discuss modifications to WP 6502 to utilize some of the capabilities of the C1S C2s and C1E C2E monitor ROMs 1 I have modified the video output section of my C1P in order to get 32 characters per line This capability is sup ported by the C1S and C1E monitor ROMs Currently the View command does not utilize this expanded video It would be ideal to modify the Type and L Edit commands also but as I indicated in the first article those commands re quire the use of the RUBOUT key for backspacing The RUBOUT key is masked out by the C1S monitor ROM so these two commands cannot utilize the expanded video In my changes to WP 6502 up to this point I have utilized the old video subroutines for the View Type Move Zap L Edit G Edit Blk View and R Tape commands The new video subroutines have been used for the W Tape and the added Print command What I will describe in this article is using the new video subroutines for the View command also Memory locations used by the non standard monitor ROMs will also have to be changed to expand the line to 32 characters I will modify the warm start code of WP 6502 to perform this This time I will reproduce most of the warm start code because it has been
