[Coco] Alternate font sets

Sat Aug 27 07:00:37 EDT 2016

Art, another such program was Steve Bjork's "Mouse" which he published in Rainbow (3 part asm listing, starting in June or July 86?). It allowed you to use the Coco normally in a PMODE4 screen with custom fonts and a few other nice features like hires interface support. I used it while I had a Coco2, but it didn't work with games that wrote directly to the $400 area.
You could run rom/ram and put it above disk basic and it didn't even take up Basic memory.

Come to think of it, there were a number of programs that pitched into theprint command and rerouted its output to a graphics screen.  I recallincluding one on the original ADOS disk called RSV, so you might give thatone a try with your adventure games.  The ADOS disk is here:  http://www.colorcomputerarchive.com/coco/Disks/Operating%20Systems/ADOS%20(SpectroSystems).zip(Thanks for posting it, Barry!)As Bill pointed out, adventure games often poked text directly into screenmemory, and it won't work in such cases, or in cases where there's a memoryconflict.  (I think RSV was relocatable, but I'm not sure.)  It is alsopretty simple to change the number of characters per line, though I don'trecollect the details--might be as simple as changing the PMODE value and anumber-of-chars-per-line value in the Basic loader program for it.  I thinkit gave a 42-column screen by default.ArtOn Fri, Aug 26, 2016 at 6:30 PM, Bill Pierce via Coco <coco at maltedmedia.com>wrote:> Ron, for DECB, most adventures use the HW 32x16 text screen and that can't> be alterred without external hardware.
