These are services that we believe the hardware is capable of providing, but require programming effort to implement. There is no commitment to do this work, but we are open to volunteers who would like to contribute to this project.
Items shown in green have been implemented
Items shown in orange have had some proof of concept work done
FAT32 file system including directory paths, and sub-directories
Support for a USB keyboard to replace the normal keyboard, many of which now have keys that stick, or have broken contacts that are difficult to replace
Support up to 1 MB of Extended Memory
WiFi access via the ESP32 optional module. Could provide a web page interface for changing the ROM configuration and other options. Could also provide a way to import/export files over WiFi in a host independent way. Just need a computer with a browser
Emulation of other contemporary computers of the HP-85
PDP-8/E with OS/8 - This could provide the following languages
OS/8 FORTRAN II
OS/8 FORTRAN IV
OS/8 FOCAL 1969 with UW extensions
Plus get to play with the operating system that was the basis for CP/M, MSDOS, and even the command box on current MS Windows
CP/M with Z80 emulation - This could provide all of the vast software available for CP/M including compilers for BASIC, C, FORTRAN, PASCAL.
Lisp support as a scripting system for the background operations of EBTKS
Support ADC/DAC via the QWIIC connector or the 40 pin header.
Provide accelerated Floating Point, Matrix operations, Vector Floating point
Implement the System Monitor board that supports breakpoints and co-operates with the Assembler ROM.
Custom Logic Analyzer for tracing all 1MB5 traffic.
Realtime, non-invasive code traces at the machine-code level.
Improvements to the Logic Analyzer using the system Symbol table
Improved diagnostics vs Service ROM for some functions. No reliance on any specific hardware functioning.
HP-85 ODT (ODT is a low level debugger for PDP-15, PDP-8 and PDP-11 minicomputers. It is an acronym for Octal Debugging Technique)
Configuration menu system
Screen capture to external printer or to PDF file
External screen support, or mirrored on a host computer
Support a wider screen buffer, adding horizontal scroll to existing vertical scroll
