Parts List¶
There are a few items that can’t or shouldn’t be purchased from the usual electonic part distributors (unavailable or too expensive):
- QMTECH Spartan 6 FPGA board or clone. Approx $27 USD shipped to USA. QMTECH has two Spartan 6 boards, one with SDRAM (green) and one with DDR3 (black). Be sure to get the SDRAM one. Though not currently used by Multicomp or PDP-10/X, I have ported Will SowerButt’s socZ80 design, which uses SDRAM, to the board.
- Xilinx Platform Cable USB Programmer. I use one available from Waveshare, but cheaper on Ebay/AliExpress. On Ebay/AliExpress, make sure you get the version that has the small breakout board and extra cables.
- A USB-to-serial adapter if you want to use TTL-level serial port. The board is designed to use the Adafriut FTDI Friend . Other breakout boards may be compatible.
- Or, a USB-to-serial cable if you want to use the RS-232 version of the serial port.
- A 5V, 2A, 5.5mm x 2.1mm regulated DC power supply (wall wart). Very common, buy at your favorite supplier.
- A 6-32 screw and nut for the LM1086 voltage regulator.
- [Multicomp] A microSD breakout board. Search Ebay/AliExpress for “arduino mini microsd module.”
- [Multicomp] A 1 GB or greater microSD card (SDHC).
- [PDP-10/X] A 256 MB or greater compact flash card, and some way to get a disk image onto the flash card.
- [PDP-10/X] A compact flash to IDE adapter. They are available here on NewEgg.com. Also available cheaper on eBay/AliExpress, but make sure the picture matches the NewEgg one.
