I.D. Industrial Monitors e’ in grado di fornire monitor
EGA compatibili con praticamente tutti i modelli presenti sul
mercato.
EGA L' Enhanced Graphics Adapter arrivò qualche anno
più tardi, nel 1984, e apportò dei notevoli miglioramenti
rispetto alle CGA. Si potevano usare 64 colori (di cui 16 contemporaneamente),
si avevano a disposizione due differenti risoluzioni (monocromatica
e alta risoluzione) e soprattutto si potevano usare gli stessi
monitor delle precedenti schede CGA.
Monitors standard EGA
I.D. Industrial Monitors offers EGA monitors that
are compatible with most models currently available on the market.
EGA
Enhanced Graphics Adapter
Videotype: TTL, 16/64 colors.
CGA/EGA uses a digital signal, referred to as TTL (Transistor-transistor
Logic), for the transmission of it's video signal. TTL is a
signal that operates on a on or off state only, thus limiting
the amount of displayable colors. Intensity bits are sued to
expand available colors up to four times the original amount.
Commonly used in low resolution computers. The Enhanced Graphics
Adapter was next in the line. It stands between the CGA and
the good old VGA cards. It was introduced in 1984 and was continued
until 1987, when the first IBM PS/2 systems were set to market.
It was a nice graphics card at the time, but it couldn't deliver
the vast array of colors we all like today, so it is thus forgotten.
It could produce 64 colors, but displayed only 16 of them at
one time when used with an EGA monitor. It had a high-resolution
mode and a monochrome mode, and was compatible with all previous
monitors, including CGA and monochrome.One new feature on the
EGA adapter was the memory expansion board. The EGA card came
standard with only 64K of memory. With a memory expansion card,
you got an extra 64K, for a total of 128K. Then, with the addition
of a special IBM memory module kit, you could add another 128K,
for a total of 256K of graphics memory. One good thing, though,
was that most "after market" EGA cards came equipped
with the full 256K of memory. (
