Classic GUS GF1 vs Primax GF1. There are couple of hardware differences, apart from the colour of PCB:
- Primax clearly uses higher quality components!
- The original Gravis uses different type of RAM slots. It had 256kB of RAM on-board, upgradable to 1MB with classic DIP modules. Primax, on the other hand had 512kB of RAM, also upgradable to 1MB, but with SOJ modules (for ex. RAM from cheap S3 trio PCI videocards).
- UltraSound Classic was one of the first sound cards that featured hardware mixer. They released many revisions, but first one that included hardware mixer was 3.7. Fortunately Primax was released after 3.7 revision and included hardware mixer as well.
- Primax is also a bit louder, about 1 and a half db.
- This card is almost 30 years old and it still sounds brilliant with its crystal clear output.
- Primax is an excellent sound card with cracking wavetable and clean output. Many games support it natively and others can be made to work using one of the emulators.
If you’re looking for an UltraSound card, this is one is as good as any!
Primax is very hardf to find! So... Grab it now!
