Testing the Interfaces on the card

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

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

Rev 3 Issues

• Micro-USB connector for power
  • Surface mount so a bit harder to solder pins
• Needs big cap rework for FT-230XS
  • See Rev 2 notes for concept

Rev 2 Issues

• 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

Rev 1 Issues

• 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

Rev 1 Prototype

• VGA connector footprint problem
• Using the J1 connector to VGAX49 card

• PS/2 Keyboard connector on RETRO-EP4CE15 works
  • Installed R1, R2 - 10K pull-ups
• R32V2020 - Land Boards 32-bit RISC CPU Works
• 40K SRAM, BASIC UK101 worked
• External SRAM works - Tested 40KB
• CP/M tested - Works with SD Card
  • Running ZEXALL
• Wrong color Mini-DIN (keyboard s/b purple)
