Platform: MS-DOS, x86
Project:
I think that I will commit to using MS-DOS on a daily basis (I did
this throughout the late 1980s and into the 1990s, in several
different professional positions.) I plan on connecting my chosen
system (see first post in my blog thread) to the internet (maybe
through an ESP modem.) Then I will try to figure out how to post to my
thread (or some other) to keep my blogging up.

Platform: Busch Microtronic
Project:
My goal is to create a multi-purpose expansion for the Busch
Microtronic Computer (1981, 4bit). I already have a Raspberry Pico set
up to emulate the Microtronic's 2114 SRAM. The Pico enables me to
store and restore Microtronic memory dumps as files to resp. from
SDcard, in milliseconds (the cassette interface takes minutes for a
decent program!) By "snooping" the address bus and SRAM (which the
Pico emulates), the Pico also knows the instruction currently being
executed by the Microtronic. I can hence turn the Pico into
co-processor, adding new op-codes to the original Microtronic. I plan
to add op-codes for OLED display output, sound, speech synthesis, a
Real Time Clock, as well as bank switching. The goal is to have a
working prototype at the end of the Challenge month that can then be
turned into a PCB (consisting of a Pico, OLED display, loudspeaker am
op-amp, SDcard, speech chip, and a few buttons for the user
interface).

I'll be making a game (or maybe several) in Assembly for the Hungarian

Platform: DEC PDP11
Project:
I have spent hundreds of hours repairing a PDP11/10 CPU box which is
now working. It is lonely for a peripheral and I have just the thing,
a PC05 high speed paper tape punch/reader.
I am hoping to get it cleaned, repaired and interfaced to my PDP11/10
and loading the DEC pdp11 paper tape basic. Utilising another
previously restored paper tape punch I will be creating the tape and
the absolute loader to suit.

Platform: Applix1616
Project:
Restoration/rebuild of an Applix1616 kit computer that hasn't been
powered up in years. Cleaning, checking all components, redoing bodge
wires, etc, through to booting the system and hopefully accessing
files on a SCSI attached volume (on a BlueSCSI V2).

Platform: Compukit UK101
Project:
I built a Compukit UK101 from a kit in February 1980. 43 years later,
I'm going to write a demo program for it. Something snazzy that'll wow
the onlookers.

Platform: VG-5000
Project:
Using an emulator to develop for a retro-machine can easily result in
code that runs smoothly but not on the real hardware. I will try to
build an interface for the VG-5000 which injects a binary and grabs
the display in an automated way. Thus exercising the real graphics
chip (EF9345). I want to compare the resulting images with the output
of emulators running the same code.

Platform: Synertec MBC020
Project:
I will focus on some 6502 projects, mostly my Synertek MBC020 ExorBus
board. I never got it working correctly as a terminal: skewed video
and no keyboard yet. Let's see if I can get all of this working
properly!

Platform: Sinclair LC3
Project:
Try to recreate the Sinclair LC3 unreleased prototype as accurately as
possible. There's not much information, but some intelligent guesswork
will do. I have inquired of both of the main people involved, not "for
information" but to ask if my thoughts and guesses were right. If it
changes, it changes, that'll teach me to write code that can be
adapted easily. I'll write some games and system software for it.
