JUMPERS

Product Information

Open your computer and locate the CD-ROM and each of the cables connected to it. Below is an example of a disc drive, including where each of the cables should connect to the drive. This card has been reported to have the hanging note bug, but the only cards I have seen have DSP v4.16 which does not suffer this. More Images Sound Blaster 16 Value edition. Most of these have the CT1978 CQM FM synthesizer chip which is almost universally considered poorer quality than a true Yamaha OPL3 chip (some CT2980 cards have the original Yamaha chip which is preferable). If it has the Yamaha chip instead, this is one of the lowest-noise SB16 cards you will find. The majority of Sound Blaster 16 cards feature either a discreteYamaha YMF262OPL-3 FM synthesizer as used on the Sound Blaster Pro II, or a Creative CT1747 chip which has this synthesizer integrated. Some post-1995 cards (notably the CT2910) feature the fully compatibleYamaha YMF289FM synthesis chip instead. All of these contain true Yamaha OPL-3 circuitry. CT2770A then followed, removing these obsolete CD-ROM interface headers from the board as well as the CSP/ASP chip area.

Fun fact... user Imperious on the Vogons forum says he successfully ran a CT2770 on an 8088 XT (8-bit ISA slots only). The 16-bit part of the card is used for the CD-ROM interface only! Imperious said it's great for running the PC speaker audio through the sound card and out of the speakers, though there's only a tiny amount of games that can use the card's abilities on a system that slow.Once connected, turn on the computer and enter BIOS setup. Verify that the IDE (integrated drive electronics) device is set up as Auto or CD Drive. Once verified, save the settings and reboot the computer. CT2771 is an odd card with no information anywhere on the web - let me know if you have any details of this card. Other Creative cards often used the '1' suffix to indicate it was a "value" version of the "0"-suffixed card, so this is perhaps a "value" on top of a "value" card ;-) Either that, or it's some OEM variant.

Creative Labs introduced the 2nd generation of Sound Blaster 16 cards in 1994, starting with the CT2230. The key difference from the 1st generation is that the Yamaha YMF262 was now gone as a discrete chip. Instead Creative Labs integrated the YMF262 into their own chip called "CT1747". These chips got the official "OPL" logo stamped on them, as they did contain the Yamaha circuitry inside. Also sadly gone was the hardware thumbwheel volume control. The CT1790, also called Sound Blaster 16 Sony is the same as the CT1740 but with a Sony CD-ROM interface. More Images Several versions of the CT2501 ViBRA-16 chip exist, including CT2501-TBQ, CT2501-TCQ and CT2501-TDQ. The Sound Blaster 16 ASP comes with a powerful mix of applications, including two programs for sampling in Windows. WaveStudio is limited to sampling and editing what will fit in system memory (about a minute of 44 kHz sampling). If that's enough, you'll enjoy its intuitive interface and strong editing capabilities. Soundo'LE is the appropriate application for creating longer samples and embedding them into OLE-aware applications. The Sound Blaster 16 mixer, which you can access from Soundo'LE's menus, is very powerful and easy to use."InfoWorld, 11 Jan 1993 CT2772 was the same as the CT2770A, but got FCC ID: IBACT-SB16NCDR, which I can only assume means "No CD-ROM", as it didn't come with a CD-ROM interface, but this card did come with a wavetable header which is odd for a value edition card...

Attach cables

The CT1770, actual name Sound Blaster 16 SCSI-2, was the first Sound Blaster 16 card from Creative Labs to come with a SCSI-2 CD-ROM interface instead of IDE or other proprietary interfaces from Panasonic, Mitsumi and Sony. To support this SCSI interface, the card has an Adaptec AIC-6360L controller chip - you need to install an ASPI driver for this chipset from your CONFIG.SYS file followed by the usual MSCDEX in your AUTOEXEC.BAT. The CT2919 was the non-"Value Edition" version of this card, designed for the OEM market. More Images Board revision 29409 was the original CT2770 and still had the other CD-ROM interface solder pads for Mitsumi and Sony drives, plus the CSP/ASP chip solder pads. They made these same cards from 1993 through 1995, so DSP versions 4.05 through 4.13 were all used.
