Aztech AT-3300 Audio Telephony (Audio/Gameport/Modem) combo card

Aztech Lab was a Canadian company.
They shipped some Audio+Modem combo cards.

I own one detected as AZT3002 PNP by Windows 95 (PNPID: AZT3002) while it has been marketed as Aztech AT3300-E (AT for Audio Telephony - E for Europe).
The ones with a PNPID of AZT3001 are AT3300-U (U for USA).
It seems it was used in some HP, Packard Bell and Compaq machines.

The card has the following chips:

• Sound: Aztech AZT2320
• Modem: Rockwell RCV288DPi

For a lot more details about the Aztech sound cards family:

• Purple Paws: Aztech ISA sound cards.
• DOS Days: Aztech

Setup

The sound card is installed in the scenic pro and I use the Universal ISA PnP Sound Card Driver for DOS (UNISOUND81b.zip) with the following configuration in autoexec.bat:

REM A2x0 = Memory address port (220, 240, 260, ...)
REM Ix   = IRQ used by the sound card (5, 7, 11, ...)
REM Dx   = DMA channel (0 or 1)
REM Tx   = Sound card type (1=SoundBlaster, 2=SB1.5, 3=SB2, 4=SBPro, 5=SBPro+FM, 6=SB16)
REM Jxxx = Joystick/game port (xxx=hex port). J0=Disable.
REM Pxxx = MPU (MIDI) port address (330 is default). P0=Disable. 
SET BLASTER=A220 I5 D1
LH C:\SYS\UNISOUND.COM

Note: I was unable to achieve FM sound under MS-DOS either with UNISOUND.COM 8.1b

For the drivers, available data are:

• Universal ISA PnP Sound Card Driver for DOS
• Mirror of Aztech's FTP with the Audio Telephony drivers (ftp.zx.net.nz)
• The complete dump of the Aztech's FTP (Vogons) (ISA sound cards only)
• Aztech Audio Telephony AT-3300 driver page (Wayback machine)
