It should be directly importable into their order system. [[https://www.retrobrewcomputers.org/lib/exe/fetch.php?media=boards:other:parportprop:parportprop_mouser.xlsx|ParPortProp_Mouser.xlsx]] \\ ====== ROM Programming ====== Operation of the ParPortProp requires appropriate firmware be programmed into the 24LC512 serial EEPROM (U5). This firmware controls the operation of the on-board Propeller processor which automatically loads the firmware at startup. Once the Propeller has loaded the firmware, it will initialize all peripherals and begin waiting for commands from the host Zeta. Since the ParPortProp is purely a slave processor for a host Zeta, it is also necessary that the host Zeta be programmed with an appropriate ROM image that includes support for an attached ParPortProp. Both the Zeta and ParPortProp ROM firmware images are included in v2.0 or greater RomWBW distributions. At this time, RomWBW v2.0 is a beta release and can be found in the RomWBW folder. The file is called “RomWBW2-Beta.zip”. Download this file onto your local machine and unzip it with any standard decompression tool. Once this is done, you can follow the instructions below to complete the programming of the Zeta and the ParPortProp. ===== Zeta ROM ===== Within the RomWBW distribution, you will find a directory called Output. This directory contains a large number of pre-built ROM images. You will need to program either the “zeta_ppp.rom” or the “zeta_ppp_z.rom” image into your Zeta ROM. Both of these have support for the ParPortProp. The “_z” version is based on the Z System OS and the other one is based on the CP/M 2.2 OS. Initial programming the Zeta ROM is accomplished using an EPROM programmer suitable for your (E)EPROM chip. Selection and use of a programmer is beyond the scope of this document. Reprogramming a Zeta ROM can be performed on a live, running system using David Giles in-situ programming application called FLASHZ. Documentation for this application is included in the Doc directory of the RomWBW distribution. ===== Propeller ROM ===== Within the RomWBW distribution, you will find a directory called Support. Within this directory is a directory called ParPortProp. This directory contains a pre-built ROM image for the ParPortProp. The file is called “ParPortProp.eeprom”. Programming of the ParPortProp EEPROM can be accomplished in any of the following ways: Via a standalone EEPROM programmer Via a serial cable to the serial port on the ParPortProp Via a PropPlug adapter available from Parallax For #1, selection and use of a suitable programmer is required and beyond the scope of this document. For #2 or #3, you must download the Propeller Tool from Parallax (free). This tool includes documentation on using either a serial cable or a PropPlug to program your device. In a nutshell, you will follow this procedure to program the ParPortProp.eeprom file: Start the Propeller Tool Use File → Open… to select and open ParPortProp.eeprom Choose “Load EEPROM” from the subsequent “Object Info” dialog box. ====== PCB Versions ====== ===== PCB Version 1.1 (Current version) ===== Increased prototype area pads' drill diameter to ~ 1 mm (40 mil) Added two holes by the crystal for a mounting bracket C12 reference switched with C13, changed C13 (3.3V rail filter capacitor) capacitance to 100 uF Added C14 100 uF filter capacitor by SD card socket ===== PCB Version 1.0 ===== Fixed errata from the prototype Changed board dimensions to match Zeta SBC dimensions Improved VGA DAC design Added resettable fuse for keyboard and VGA 5V Added jumpers for RTS/CTS and DTR/DSR loopbacks Added prototype area Errata (to be fixed in the next PCB version): C12 should be 47 uF instead of 10 uF. Sergey says: I get wavy video if 10 uF is used, issue disappears with 47 uF. ===== PCB Version 0.9 (Prototype) ===== Errata (to be fixed in the next PCB version): Pin 1 hole of P5 is too small Solder mask covers D1 pads on the solder side Add pin 1 location marks for P4 and P5 Connect VGA pin 9 to Vcc Check PropPlug pinout (pin 3 & pin 4 reversed?) ====== File List ====== Filename Filesize Last modified [[https://www.retrobrewcomputers.org/lib/exe/fetch.php?media=boards:other:parportprop:parportprop_-_board_-_color_-_0.9.pdf|parportprop_-_board_-_color_-_0.9.pdf]] 565.4 KiB 2015/12/08 19:55 [[https://www.retrobrewcomputers.org/lib/exe/fetch.php?media=boards:other:parportprop:parportprop_-_board_-_color_-_1.0.pdf|parportprop_-_board_-_color_-_1.0.pdf]] 2.0 MiB 2015/12/08 19:55 [[https://www.retrobrewcomputers.org/lib/exe/fetch.php?media=boards:other:parportprop:parportprop_-_board_-_color_-_1.1.pdf|parportprop_-_board_-_color_-_1.1.pdf]] 2.0 MiB 2015/12/08 19:55 [[https://www.retrobrewcomputers.org/lib/exe/fetch.php?media=boards:other:parportprop:parportprop_-_schematic_-_color_-_0.9.pdf|parportprop_-_schematic_-_color_-_0.9.pdf]] 76.7 KiB 2015/12/08 19:55 [[https://www.retrobrewcomputers.org/lib/exe/fetch.php?media=boards:other:parportprop:parportprop_-_schematic_-_color_-_1.0.pdf|parportprop_-_schematic_-_color_-_1.0.pdf]] 211.2 KiB 2015/12/08 19:55 [[https://www.retrobrewcomputers.org/lib/exe/fetch.php?media=boards:other:parportprop:parportprop_-_schematic_-_color_-_1.1.pdf|parportprop_-_schematic_-_color_-_1.1.pdf]] 179.2 KiB 2015/12/08 19:55 [[https://www.retrobrewcomputers.org/lib/exe/fetch.php?media=boards:other:parportprop:parportprop_mouser.xlsx|parportprop_mouser.xlsx]] 12.1 KiB 2016/05/11 16:06 [[https://www.retrobrewcomputers.org/lib/exe/fetch.php?media=boards:other:parportprop:parportprop_side.jpg|parportprop_side.jpg]] 166.2 KiB 2015/12/08 20:51 [[https://www.retrobrewcomputers.org/lib/exe/fetch.php?media=boards:other:parportprop:parportprop_top.jpg|parportprop_top.jpg]] 173.2 KiB 2015/12/08 20:51 [[https://www.retrobrewcomputers.org/lib/exe/fetch.php?media=boards:other:parportprop:parportprop_v1.jpg|parportprop_v1.jpg]] 395.9 KiB 2015/12/08 19:53 [[https://www.retrobrewcomputers.org/lib/exe/fetch.php?media=boards:other:parportprop:parportproptest.zip|parportproptest.zip]] 79.1 KiB 2015/12/08 20:51 [[https://www.retrobrewcomputers.org/lib/exe/fetch.php?media=boards:other:parportprop:ppp_-_gerber_-_1.0.zip|ppp_-_gerber_-_1.0.zip]] 468.3 KiB 2015/12/08 20:52 [[https://www.retrobrewcomputers.org/lib/exe/fetch.php?media=boards:other:parportprop:ppp_-_gerber_-_1.1.zip|ppp_-_gerber_-_1.1.zip]] 469.1 KiB 2015/12/08 20:52 [[https://www.retrobrewcomputers.org/lib/exe/fetch.php?media=boards:other:parportprop:ppp_-_kicad_-_1.0.zip|ppp_-_kicad_-_1.0.zip]] 252.0 KiB 2015/12/08 20:52 [[https://www.retrobrewcomputers.org/lib/exe/fetch.php?media=boards:other:parportprop:ppp_-_kicad_-_1.1.zip|ppp_-_kicad_-_1.1.zip]] 250.9 KiB 2015/12/08 20:52
