IBM PC 8-bit ISA Bus Prototyping Extender Riser Card PCB FR4 with edge connector

Description: IBM PC 8-bit ISA Bus Prototyping Extender Riser Card PCB board FR4 Double sided XT 8088 GREEN solder mask IntroductionThe ISA 8-bit extender riser card is a specialized type of test card that is typically used in industrial and commercial settings for production testing, prototyping, diagnostic and troubleshooting of ISA or footprint compatible cards.Extender card is inserted into the ISA slot on the backplane or motherboard, and then the ISA card under test is inserted into the PCB edge connector socket on the riser card. This setup enables users to test the card in situ for issues without the need to remove it from the motherboard. This is particularly useful in situations where the tested cards are challenging to access and/or devices require disassembly, which can help users to diagnose issues that may only occur when the PCBs are connected to the system.I have originally designed this backplane for few of my projects, but this turn out so well that I have now posted all schematic, gerber files and documentation to fellow enthusiast such as yourself. Perhaps (and I hope) content in this obscured corner of interwebs will inspire you to start your own projects.Design overviewYou will usually fit this card in industry standard 8-bit ISA PCB edge card connector. Riser extender card his will also fit into 16-bit connector, however only 8-bit bus functionality is supported in this case. For 16-bit applications please refer to IBM PC AT 16-bit ISA Bus Riser Extender Card. PCB was designed according to standard mechanical dimensions, therefore connectors' mechanical positions will match perfectly with PCB edge connector and rear PC brackets should you decide to use this solution.Main design features:Tested and proven design with many revisions. Raiser Extender PCB has been designed to be very flexible and can be used with large variety of industry standard power and signal connections: ■ Signal traces - (passive termination) are not terminated nor have determined pinouts; allowing you to configure the backplane to exactly match the requirements of the system. Traces are wide apart thus minimizing crosstalk. ■ Test points - The riser card features 3x32pin AB rows for test points and sports test point loops or 0.1" Dupont header connectors footprint that facilitate easy injection of test signals and/or monitoring of bus signals with test equipment (oscilloscope, logic analyser, multimeter etc.) during the manufacturing and testing of the PCB. ■ Power connectors - Power tracks size increased for higher power rating and noise suppression. Separation of all power and ground traces to ease trouble shooting. Bracket mounting holes are not electrically connected. ■ Mechanical - PCB format is large enough to be robust and extend card under test above majority of PC cases due to leght of 169mm (including connector). PCB footprint (from v1.3) accomodates holes for installation of rear PC case bracket. PCB sports standard 2x31pin connectors with 45° chamfered edge for easy insertion and comes with industry standard 62pin (2x31 pin) ISA Bus edge connector.When using a riser extender test card, it is important to exercise caution when working with sensitive electronic components. Users should ensure that the device is turned off before inserting or removing any cards under test. This precautionary measure can help prevent damage to the components and the system.These boards look absolutely gorgeous in standard green solder mask if you going for that standard industrial look. I can supply you with rear support bracket at extra cost. Rear bracket is supported by 3D printed parts.
