Looking for info on my sound card (opens in new tab)

Hello, New to this forum. I have an old Pro Audio Spectrum 16 ISA card I’ve had in storage for about 25 years. It has the model # 650-0022-01-G . Everything I can find on these cards says there are only revisions A-F. Manufacturing date on both the circuit board and the chips show 1992. It has the usuals: A DB15 MIDI/game port, the Line In & Out and Mic in, as well a CD in and speaker out, and a 50-Pin SCSI, etc. It definitely shows the “G” very prominently and it couldn’t be any other letter...
