Hello all. I've been trying to find jumper settings for the this drive controller but am not having any luck. It's a 16-bit ISA card with 17 jumpers identified at W1-W17. A photo is attached.
The PCB top copper layer says:
"STB SYSTEMS" "FAB REV.B" "210-0078-002"
The EPROM labeled "AT RLL 2.5" contains the following strings:
SN 00000000000000000 (not masked, they are all zero)
REV 2.4
MODEL NUMBER ATRLLC
The EPROM labaled "RLL BIOS 3.0" contains the following strings:
STB Systems, Inc. AT/RLL(2,7) Controller ROM Bios Vers. 3.0
(c) Copyright 1990, Chips and Technologies, Inc.
STB Systems, Inc. AT/RLL(2,7) Hard Disk Format Utility Version 3.0
As well as a bunch of text relating to an integrated low level format utility user interface.
It also contains 32KB and 2KB SRAM's. I'm a bit surprised I couldn't turn anything up with Google with the STB brand and the model/ROM information. Any information would be very much appreciated. Thank you.
