Hello everyone and thank you for accepting me on the forum. My name is Patryk, I live in Poland.
I have such an interesting and not very common motherboard
This is what I know about it:
-CPU: 486 Socket PGA168
-Fcpu: 66.6667MHz
-Chipset: OPTI 82C496-B1 and Siemens SAB 82C206-N - probably supports up to 64MB RAM
-4MB EDO RAM chip (8 x GM71C4400AJ-70 chips)
-Three 72-pin SIMM sockets with the possibility of adding up to 64MB - this is the theoretical support of the chipset
-Graphics on the WD90C30-ZS chip, 1 MB DRAM Siemens 4x HBY514256BJ-70 plus the possibility of adding 1MB to 2MB- 4 soldered sockets for ZIP and four free spaces, goldpins described as Video Feature, VGA and Hi-res SVGA output
-2x serial port (one on the board, the other on the goldpins), parallel port, AT keyboard socket, PS/2 mouse socket, Floppy Drive socket, Hard Drive socket.
-Motherboard from 1992.
The board is marked SBR247.
Google and The Retroweb are silent on the subject.
So I am asking for the identification of this board. Maybe someone knows who is the manufacturer of this board, where it was used.
If someone has the same board, would they be able to download BIOS to it and provide the EPROM/EEPROM model? and take pictures of the expansion card? I am missing the BIOS and the expansion card.
Best regards,
Patryk
