Well, here's a more realistic test, reading and printing 16 × 16 slides from DATA statements. With BASIC 2.0 more like 1.5 fps… :-)

BASIC 2.0 (slow PRINT): https://masswerk.at/pet/?prg=hn-globe-slides-test&rom=2

BASIC 4.0 (faster PRINT): https://masswerk.at/pet/?prg=hn-globe-slides-test&rom=4

The main part of the program is:

  10 PRINT CHR$(147)
  20 FOR F=0 TO 16
  30 PRINT CHR$(19);:FOR R=0 TO 15
  40 READ A$:PRINT TAB(12)A$:NEXT
  50 NEXT
  60 RESTORE:GOTO 20
