I acquired as Hyperion 512K card from a third party, made by Kim a while back. Yesterday was the first day that I tried to use it, in place of a Saturn 128, or Lang card, and I must report that it is unreliable. Abouit 40% odf the time, ProDOS 2.4.2 loaded, the rest of the time it wither crashed before finishing launch, or alishtly thereafter.
Am I missing something?!
I installed it in Slot 0, and I had a full bank of normal 48K RAM. The LEDs on the card illuminated, indicating that it was in use, but it still crashed more than half of the time.
A normal language card works speledidly w/o issues.
