Testing the Interfaces on the card[edit]

Here's a way to test the interfaces on the card, including the 1MB SRAM.

  • Requires
    • VGA display
    • PS/2 keyboard
    • Host PC running PuTTY over the USB-serial interface
  • FPGA build - OSI M6502 VGA Multicomp - VHDL code - Build/Load to FPGA
    • 40KB Internal SRAM used by BASIC
  • 1MB External SRAM banked as 128 banks of 8KB in the M6502 space
    • Bank select register at 0xFFD4
    • 6502 address space from 0xC000-0xDFFF
  • Load RAM Test BASIC program - Loads/runs under OSI M6502 Multicomp build
    • Test the Bank Register works by incrementing the register filling the first location with the bank number and verifying all writes worked
    • Tests single 8K
    • Between these two tests checks all data, address and control lines to the External SRAM
    • Steps to load/run
      • Run FPGA code and hit enter on PS/2 keyboard until power on tests are done and BASIC prompt is on VGA
      • Open BASIC program BANKTST2.BAS (above) in text editor
      • Run Serial port run terminal emulator, like PuTTY
      • On PS/2 keyboard, Press F1 to select serial port instead of VGA
      • Copy BASIC program (Ctrl-A, Ctrl-C) to copy/paste buffer
      • Paste into PuTTY (right click in PuTTY window)
      • Type "RUN" on PuTTY terminal
      • Result will be printed to the screen
      • Runs fairly quickly, the OSI M6502 is a 12.5 MHz design (slowed down for external SRAM)
  • Test SRAM - Alternative test of External SRAM using 6800 MultiComp build

Rev 4 Issues[edit]

  • Built and tested, no issues
  • USB-B much easier to solder

RETRO-EP4CE15 P17471 720PX.jpg

Rev 3 Issues[edit]

  • Skipped Rev 3

Rev 2 Issues[edit]

  • GND on wrong USB pin
    • Was pin 4, s/b pin 5
    • Cut etch J4-4 to via
    • Add wire J4-5 to via
  • FT230XS +3.3V out needs 10 uF cap (min)
    • Added 47uF electrolytic cap between via GND and vusb (3.3V) on rear of board
  • USB micro inconvenient to solder

RETRO-EP4CE15-CAP-REWORK-P966-445PX.jpg

Rev 1 Issues[edit]

  • Wrong DB15HD footprint
    • Change to right footprint in Rev 2
  • USB-C too hard to hand solder
    • Changing to USB-B Micro in Rev 2
  • Add 5V header in Rev 2
