Hi all,
Need help with identification of some cards which I've found inside of Dell Dimension M233a.
Never seen anything like it before, especially those two ISA cards with two Cirrus Logic GD5428 processors on each card and 37 pin d-sub connector ???
Also another cards which I have no clue what it is.
Anyone knows what are these cards??
Thanks
Looks like a system with previous industrial use...
...top two pics are likely data acquisition cards (488.2 on the bottom one refers to IEEE 488.2)
"GPIB (General Purpose Interface Bus) was developed as an interface between computers and measuring instruments. It is mainly used to connect PCs and measuring instruments. GPIB was created as HP-IB, an in-house standard developed by Hewlett Packard, which was approved by the IEEE (Institute of Electrical and Electronics Engineers) and became an international standard. Many current measuring instruments support the GPIB interface as standard, and it is widely used in measurement systems using PCs and measuring instruments.
GPIB standards include IEEE-488 and the higher-level protocol IEEE-488.2, which is currently mainstream. In addition to the transfer methods specified in IEEE-488, IEEE-488.2 features syntax for text data and numeric expressions, and commands and queries that can be used by all instruments. IEEE-488.2-compatible instruments can communicate with other IEEE-488.2-compliant devices and with IEEE-488 devices within the scope prescribed in IEEE-488."
Would guess multi-chip CL cards are for some form of associated multi-monitor display, probably on breakout cables from the 37 pin d-sub connector.
