I've just uploaded a scan of my (xeroxed) manual for the "C7420 Home Computer Module" to @internetarchive.
The C7420 is a #BASIC cartridge with #Z80 CPU and RAM expansion for the Philips #G7400 (#MagnavoxOdyssey2) #Videopac+ video game console.
I did not find any manual for that online - neither Enlish nor German. So, here you are:
I've been working on optimizing Terminal performance, it used to REALLY lag out on long text printing across lines or scrolling.
Not now! It's too fast to measure! Tho I lost the pulsing cursor, but even if I put that back it'll still be drawing at native speed.
I don't want to write a buffer to make it slow down to some terminal speed, but I kinda ought to. Or add a PAUSE command so you can make fake slowdown.
Also maybe text aligned better on non-Safari?
