Project:
Diving deep into PC-9801 sound cards, specifically the PC-9801-26(K).
Cloning hardware, learning the Sound BIOS, learning how the computer
communicates with the card, and maybe even interfacing a new sound
chip to the system! Also possibly various other small PC98-related
projects in case of downtime or burnout.

Platform: Compukit UK101
Project:
A re-implementation from scratch of The Valley, as published in
Computing Today magazine, April 1982. I originally started working on
this during August, but the project has fallen by the wayside since.
The RetroChallenge seems an ideal opportunity to start this project
again. No cheating everything will be / has been typed in by me (and
debugged!), just as I did in 1982 on my Sharp MZ-80K.

Platform: Sun4u (Sun Ultra 45 Workstation)
Project:
I'm going to make a Pleroma instance (https://pleroma.social, same
protocol as Mastodon) run on the last Sun SPARC workstation model
made, a Sun Ultra 45. I literally came up with this idea last night
right before October 1st but tomorrow is Saturday and I'm off work and
I'll be able to start on it and have a nice post up then. If I can't
get it working there, I've got various other vintage non-x86 systems I
can attempt it on.
This is also interesting because Pleroma and ActivityPub/the fediverse
is the true future of social media and decentralized like e-mail is.
It's also much better than Twitter.

Platform: NEC mini5 word processor
Project:
In Japan, NEC released a series of word processors that are actually
secret CP/M computers. I've bought two, so I will try and run Zork on
one, and fix another. Why bother buying a broken one? It came with
Tetris. Yep, Tetris for a word processor, which I plan to dump.

I'm building a single-board computer based around the Zilog Z180. My
goal is to have a working prototype by the end of the challenge that
includes serial ports, an LCD display and PS/2 keyboard input. Stretch
goals: USB storage, and getting a PCB manufactured.

Platform: Xenix
Project:
Add support for Xenix filesystems to my retro-fuse project.
Retro-fuse is a user-space filesystem (FUSE) for accessing ancient
unix filesystems on modern OSes. I need to learn how to install and
run Xenix systems in simulation, reverse-engineer their filesystem
layouts, and adapt existing ancient Unix code to read and write these
filesystems.

Platform: SC/MP Miniscamp and Maximite
Project:
Like me, you may have a 1977 EA Miniscamp microcomputer tucked away.
It is fun to get out every now and again, but it is very tiresome
having to enter in the machine code via the front panel switches.
And also like me, you probably have a Maximite computer tucked into
the same cupboard next to the Miniscamp.
This simple interface will allow the Maximite to drive the front panel
switches of the Miniscamp, thereby allowing the tedious procedure of
programming the Miniscamp to be programmed, and for those programs to
be stored on the Maximite and quickly loaded into the Miniscamp.
Other goals:
- Expand the RAM
- Run KITBUG
- Add a USB serial interface

Project:
I will be attempting to boot an Apple IIe from an AppleShare file
server. The twist is I will be using an Apple IIe Card installed in a
68K Macintosh to boot via LocalTalk to AppleShare Server 3.03 running
on an SE/30. I will also be trying to do it all with original hardware
and software. I have a stretch goal of trying to do this via firstly
LocalTalk and then Ethernet.

Project:
My goal is to create an all-in-one GeoCities Apache web server that
fits in the palm of your hand. RetroChallenge 2021/10 was a test run,
it went darned well. We need our retro hardware, 386/486 and newer, to
be able to revisit the internet of our past.

Im going to attempt to restore functionality of a Data General Dasher
386-25K Model 91862 PC from the early 1990s. Theres no POST as far as
I can tell but it does power on, even though there looks to have been
some liquid damage after opening it. Id be keen to play some
Microsoft Solitaire if I can get this beast purring again.

Platform: Windows 2000/XP
Project:
I want to make a Twitter client for Windows 2000/XP (maybe also 98 if
I can find time to make some widgets that work on 2000 but not 98). I
started this a while ago but didn't get all of it finished. Maybe
Retro Challenge is enough of a motivation to revive it?
It's going to be an awful twitter client, but I think it should work!

Project:
I intend on using this month to learn how to program for vintage Mac
OS, specifically System 7 and Mac OS 8/9. Most likely will be some
simple game like Pong, or some kind of useful utility application.
I've wanted to do this for a while but never had enough motivation, so
RetroChallenge seems to be the perfect time to get started on this :3
