The Archiver makes use of certain models of the Diablo Model 31 disk drive to read the contents of 2315 disk cartridges that were used on an IBM 1130 system, then export the archived contents to files on a PC, Mac or other system.
The main logic for the archiver is implemented in Verilog on a Digilent Arty S7 FPGA board but that requires a custom printed circuit board to manage the electrical requirements of the Diablo disk drive and the voltage maximums of the FPGA board. I designed a board to accomplish this.
PCBWAY.COM SPONSORING THE MANUFACTURE OF THE CIRCUIT BOARD
I uploaded the design to PCBWay.com who have offered to sponsor the production of the board. It is a four layer board, less than 4 by 5 inches, that installs on top of the Arty S7 FPGA board. It provides power to the FPGA board and its own circuitry, driven by a 9V wall wart DC supply. A 50 wire ribbon cable with an IDC connector - commonly used for SCSI internal drives - connects the PCB to the connectors on the rear of the Diablo drive.
Above is the visualization from the PCBWay.com web site of the front of my board. The order was uploaded and I expect to have the completed boards in a couple of weeks. I chose non-standard solder mask and silkscreen colors which adds about half a week to the production versus standard colors.
COMPONENTS ORDERED FROM DIGIKEY
I also ordered all the parts for the PCB construction from Digikey. They will arrive before the board so that I can move directly into construction once I have the circuit board in my hands.
GITHUB PROJECT STARTED
I opened a Github repository to share all the files related to this project - board designs, Verilog code, documentation and pictures - so that others can build this if they have IBM 2315 cartridges whose content they want to archive.
