The mode definition file changed two times.
In NetBSD 1.0 all horizontal values were videoclock cycle values instead of pixel values:
 num clk      wid hi  dep hbs hss hse hbe ht  vbs vss vse vbe  vt
In NetBSD 1.1 and NetBSD 1.2:
 num clk      wid hi  dep hbs hss hse hbe ht  vbs vss vse vbe  vt
the vertical values were used to select the interlace or doublescan mode. All vertical values were half the width for the interlace mode and twice the width for the doublescan mode.
Beginning with NetBSD 1.3:
 num clk      wid hi  dep hbs hss hse ht  vbs vss vse vt  flags
hbe and vbe are computed in the grf drivers.
