"9143" is the year/week code. 1991, 43rd week.

TV might mean it's Texas Instruments... Is there anything on the back?

I dont see it in TH99

The big IC there is likely the multi-IO, not the IDE logic.
https://www.alldatasheet.com/datasheet-pdf/pd … 2/TL16C451.html
(the --452 is a version of this chip with an additional parallel port, and some other goodies.)

(on the assumption that TV is a variant of Texas Instruments, as per above)

The SPC2052F is apparently an NEC compatible floppy diskette controller chip.

Looking at the traces (my eyes are crap anymore), it looks like the chip that actually drives the IDE controller is the small quad package there, with GG05 JAPAN written on it.
I cant seem to find a data sheet on this IC though.

I am guessing that this is a very simplistic 16bit IDE controller with no real meat to it, other than some latching and address decoding.

I presume that you want to identify this device so that you can configure the DIP block. More than likely, since we have silkscreening on the board that identifies where IRQ assignments are given, this dip block controls the IO base addresses of the IDE controller, the serial ports, the game port, and the LPT ports.

I would suggest going through it in a binary sequence and recording what happens with each toggle.

After work, I’ll upload more images.. (close ups, backside)

New images...

Thnx in advance

If you want to figure out which dipswitch does what, the advice given of setting one, then booting the computer and using a program like checkit or microsoft diagnostics, norton sysinfo, or one of the other programs that can be found these days that show information about your system is good advice, then make note of the available ports, game/serial/parallel/fdc/ide, shutdown the computer and repeat the steps for each individial switch, whilst setting the previous one back off.

your card has six ports.
floppy, IDE, two serial ports, one parallel port and one game port.
a fair assumption is that there is a dipswitch for each of these to enable or disable them, which leaves two which I think are used in pair with another one to set the port address for the parallel port, and another one which forms a pair to select the address for the serial port, though this could also be to set the ide port or floppy port to another address. if it is for serial, it likely switches COM1/2 to COM3/4

have fun.

Thank you. I'll admit I was hoping to find web info on the card. As of right now it is fully functional everything works as advertised.
In my research to catalogue all components in all my builds, I could not locate anything on this card. This is why I'd reach out to all the vast knowledge in this group.

Cheers.

Da, except for the chips, they are similar.

Sometimes you get a chance to add to it instead. 😉

Those chips are commodity chips. SPC2052F = Floppy controller. 16C452 = 2 serial ports and an LPT port. There were dozens of manufacturers for those things and they were drop in replacements.

The only thing that is slightly unusual is the "GG055" chip. The writing on the next line looks like TL03U1006. Looks like it's involved in reading the switches above it. Doesn't look like it does anything else
