Thanks to Tim Knight for sending me the board. Further thanks to the Wizard of Oz for further #9 information.

Two RAMDAC on board, linked to a TIGA. Might this be the Bt459 for hi-color, and the Bt478 for MDA?

F1 and F2 are odd. They are two what looks to be solder pads that touch. Dunno, the idea of an exposed fusible link that might leak a little dot of solder onto the systemboard is unusual.

NNIOS, Number Nine's Intelligent Operating System Number Nine created our own graphics operating system called NNios™ (Number Nine Intelligent Operating System). NNios was resolution, color and even processor independent. NNios was a unique innovation in graphics display programming, and offered developers assurance that a single driver would support multiple boards.

MDA uses the memory range B000-B7FF while the graphics mode display uses A000-AFFF for it's color plane buffer

The Number Nine Graphics Card and Windows 3.1 (This may not apply to the Pepper SGT)
If you use a Number Nine Graphics Card Model GX with Win 3.1, you should have the TIGA display driver installed.

   Number Nine tech support recommends using the Windows TIGA display driver. You may also want to add an EMMExclude statement in the [386Enh] section of the SYSTEM.INI file. This line should read as follows: EMMExclude=C000-CFFF

NOTE: You may need to upgrade your Number Nine Graphics card if problems occur when you run Windows version 3.1.

Before S3 chips there were two generation, #9GX and #9GXi.
#9GX generation are based on NN9091, NN9092 and TMS34010FNL-50 chips

They consisted of the following models:
1) The one on your drawing with PCB PC007000-1
2) Another version with PCB   PC007200-2
3) Another version with PCB PC007208 X1
4) #9GX MCA with PCB PC007700-3

#9GXi generation are based on RITAB, TINA, FREDD and TMS34020FNL-40

#9GXi generation consisted of the following models:
1) #9GXi "Level 25", co-pro, two video ports, full length
2) #9GXi Lite "Level 20", no co-pro, one video port, 2/3rd length ISA?
3) #9GXi HC "Level 29", co-pro, two video ports, full length ISA?
4) #9GXi MCA "Level 25", co-pro, one video port, full length MCA

Note: I am unsure if the GXi are duplicates...

Framebuffer RAM 1MBit Dual-Port VRAM: M5M442256AL-8 28-pin ZIP

Note:  MCM514256A has three different packages, the "P" [20 pin DIP], "J" [20 pin SOJ], and the "Z" [20 pin ZIP].

Note: The #9GXi for MCA has an AVE [?] extension. But it might supply Base Video [like the ATI GUP]

Back to Antinomy...

After that Number Nine started using S3 (#9GXE and #9GXE64) and then the Imagine 128 came out which is more or less known. But all these cards are neither Pepper nor Pepper SGT although I've seen some #9GX referenced to like that.

The answer is in the PC Mag 12 May 1987, page 44-45.

As you can see around May, 12 in 1987, Number Nine announced Pepper SGT which is powered by a TI 34010 and an Intel 82786 chips.  - this is the real Pepper SGT referenced to as Pepper there. I've found some old ads (around 1989) selling "Pepper SGT Plus" - no idea if it's the SGT or an updated version.

The Pepper Pro 1024 appears in an article in April, 1990 so it's a later generation than Pepper SGT but earlier than the 9GX.

That's all my progress on pre-S3 Number Nine cards for now.



GXi cards use a Texas Instruments TMS-34020 graphics co-processor

Wizard of Oz spoke thusly:
From looking at this pic, I think it is a GXi in MCA, not a GX (it's even labeled GXI (should be GXi, methinks)).   (I think your line drawing is either a Pepper or a GX, but I'm 99% it is NOT a GXi.)

I have a GXi in ISA, and it is similar to this pic.  Both are different from your line drawing.  The empty processor socket is for a TMS-340x2 (?, forgot exact number) floating point co-processor.  I think the extra DIP sockets are for another 512K of DRAM (Ed. Instruction memory, I think).  As is, the card in the pic appears to have 1M DRAM + 2M VRAM, like my ISA version, though layout is a little different.  Your line drawing doesn't have a socket for the floating point co-processor.

What is interesting about this pic is it is an MCA card.  This appears to confirm that the GXi was available in MCA (assuming it is, indeed, a GXi).  However, the card in the pic only has 1 VGA output; my ISA version has 2.  One is for low res VGA, the other for Hi-res VGA.  Back in the day, a lot of graphics (CAD, etc) used one monitor for text input commands and text output, and another (the hi resolution one) for Graphics output.  So there was a form of dual monitors back in the day, but not like we have now.

I have never plugged mine in, so I can't be sure what the boot message says, so I guess that is my next project. But I believe the Pepper cards are different from the GX and GXi cards, based on driver files that were on Number Nine's site, et seq.  That article link I sent calls the cards in it the Pepper Pro 1024, and they do NOT have a socket for the floating point co-processor.  Also, that article is from 1989, and my GXi models have silk screened dates of 1991 and 1992.  The GX may be a descendant of the Peppers, but I don't think it was a Pepper.  The GXi's I'm 99% sure are not Peppers.  I think we are talking 3 different generations of cards here, like the later GXE64 and Motions, and the time frame fits in with typical generational advancements.

I have the GXi family manual, and there is no reference to the cards being called "Pepper."  As to levels, you might be partially right, but I think there is much more.  According to the GXi family manual, the GXi Lite is a "Level 20," the GXi is a "Level 25," and the GXiTC is a "Level 29."  I think part of it is board revisions, which may include memory, but that is not all.  The Level 25 and 29 are socketed for the floating point co-processor; the Level 20 (GXi Lite) is not.  Also, there are 2 VGA outputs on the Level 25 (GXi) and Level 29 (GXiTC) boards, but only 1 on the Level 20 (GXi Lite) board.  And, the 25 and 29 are full length cards, while the 20 is about 2/3 length.  (The GXE went through a number of "Levels," but they were still GXEs).  I think the Pepper Pro 1024 and Pro 1280 are different submodels of Pepper, and the number is the max resolution rate at whatever color depth they were pushing (probably true color).  I'm not sure where Pepper SGT and Pepper fit in.  More digging is needed.

I was wondering if you got that pic somewhere else, or is it your card?  It doesn't match your line drawing.  But I'm glad you sent the pic, because it shows what is apparently a GXi in MCA, so I can add that tidbit to the article.

To summarize, at this point, I think the Pepper, GX, and GXi are all DIFFERENT cards (3 different generations), there are 3 models of GXi, maybe 3-4 models of Pepper, and at least 1 model of GX.  (This is not counting ISA/MCA as different models; I'm counting different functional product models.)

So the technological archaeological dig goes on...
