Two vector units will have four million apiece and there will be four to eight million for the two million bits of on-board RAM.

A 'Pro' version added 512 kB of on-board RAM required for compatibility with GUS Classic.

All machines with colour monitors have a video card and should have at least 512Kb of on-board RAM.

The main problem I encountered concerned the 1Mb of on-board RAM, which wasn't enough for the more complicated graphics output.

Like its successor, it used the Z80A microprocessor and had only 1 kB of on-board RAM.

Inevitably, the balance was largely redressed with the introduction of the Sound Blaster AWE32 and its successors, which also featured on-board RAM and wavetable mixing.
