From what I remember, Amiga / planar kinda sucked for text scrolling. I remember dialing into ANSI BBSes and seeing that fringe / flicker effect as text scrolled. I had an 030 machine, so I ran CpuBlit to replace some of the blitter calls with the CPU: http://aminet.net/package/util/boot/CpuBlit http://aminet.net/package/util/boot/CpuBlit
- MarkusWandel 4y agoI guess super-colourful text modes were not a priority. The standard Workbench screen was a 2-plane affair and I never noticed any scroll artifacts (on the original A1000). Also perhaps not all the tricks from the video game world were applied here, e.g. "racing the beam" to update all 4-5 bitplanes in an interleaved fashion at times when they weren't being displayed. Also, didn't the Amiga have hardware scrolling, i.e. you can define a taller display than fits on the screen, and scroll through it by relocating the base address of the bitplanes, and update the off-screen part?
- tom_ 4y agoIt did have hardware scrolling, but there was no wraparound, so a bit inconvenient for an infinite scrolling-type text display. You'd have had to write a copper program to switch the start address at the wrap point.
