I never used Lotus Agenda, but I’m told it was a popular productivity tool for MS-DOS in the late 80s. I’ve been on a retro software rediscovery kick lately, so I’ve decided to give it a whirl and write about my experiences. There is something that appeals to me about using long-abandoned software. Perhaps it’s update fatigue, there’s certainly no need to dread a major update breaking something!
Regardless, I’ve always enjoyed finding new productivity tools to try out, and I’m not afraid of steep learning curves or getting my hands dirty. I’ll usually choose powerful and flexible software over simplicity.
At the moment I mostly use taskwarrior, but I’ve lost count of all the others I’ve tried!
Agenda is a PIM, a Personal Information Manager. That term has fallen out of fashion, I think a quick summary might be “anything that manages those small pieces of information we all deal with”. Things like contacts, todo lists, notes, and so on.
I found a 1989 episode of the TV show Computer Chronicles that discussed how people thought about PIMs at the time.
At the 21-minute mark there’s a demonstration of Lotus Agenda, but it’s not easy to follow, watch the clip and you’ll see what I mean. Still, you do see some interesting features:
Some form of NLP is used to extract dates and names from free-form text.
Categories are a little like what we would call tags today.
You can create custom dashboards called views.
Apparently this was an $800 software package (That’s $395 adjusted for inflation from 1989), yikes! You don’t have to pay that, Lotus made it available for free when development ceased.
In preparation for trying out Agenda, I found a copy of the original manuals on eBay for a few dollars. Just look at this monster, the user guide alone is over 700 pages, that’s not including the supplementary guides. The supplements I have are Working with Macros, Working with Definition Files, Setting up Agenda, and a few miscellaneous leaflets.
I guess that’s my bedtime reading taken care of for a while. I actually received the macro reference still in the original shrink wrap, it almost seems a shame to open it!
In the console modding scene, files matching the format of an executable ( .exe ) promising a simple "one-click" software downgrade for a PS4 are almost universally fraudulent. The Illusion of a Software-Only Downgrade
The PS4 modding community is very vocal about protecting users from scams. The ConsoleMods Wiki explicitly warns: " there are many scam sites that claim that permanent custom firmware (CFW), downgrading, online jailbreaks, retail game unlockers, and online cheats are possible. This is not true ". Sites like ps4portal.net have extremely low trust scores and are flagged as potential malware distributors. The verdict on any site or tool promising an easy, software-only system downgrade is clear: .
If you're looking to enhance your PS4 experience, consider:
Legitimate developers almost always publish their tools as open-source projects on platforms like GitHub. If a tool is only available via a sketchy file-hosting site (like Mega, MediaFire, or password-protected RAR files), it is highly suspicious.
Software that encrypts your personal files (photos, documents, games) and demands payment to unlock them.
: Fine jumper wires must be soldered directly to specific pins on the Syscon and NOR chips.
: You cannot plug a PS4 into a PC and run a simple .exe script to roll back the official firmware. 🛠️ How PS4 Downgrading Actually Works
The only viable method to revert system firmware is a . It is not for the faint of heart and is not a viable solution for most users.
While firmware downgrading is restricted, there are verified open-source tools for other modifications:
Use the PS4 Wii Tools to generate a patched NOR dump that merges the required files, specifically creating a Legit CoreOS patch.
Using unauthorized or fake software tools to alter system files can corrupt the PS4 flash memory. This can result in a permanent "brick," rendering the console completely unusable. 3. Phishing and Survey Walls
Use a hardware programmer (like a Teensy or Raspberry Pi) to dump the NOR and Syscon data to a computer.
The terminology surrounding "PS4 tool downgrade v100.exe" typically refers to third-party Windows software designed to interact with the PS4's internal hardware to manipulate its system firmware.
There is no legitimate software-only executable tool that can instantly downgrade your PlayStation 4 Go to product viewer dialog for this item.
You probably need to use other applications or services, and sync your data with your phone. Writing and reading files from outside DOSEMU is no problem, so if you just want to sync files this is no problem.
As it’s a terminal application you can also just SSH in and run it.
You probably also want to have your appointments sync with your calendar or something.
Export
There are two ways to export data from Agenda. If you have a commandline tool that you can pass arguments to, then you can write a macro that will invoke it.
Otherwise, you can export your data to a file.
Files
Agenda can export items to a format called STF, Structured Text File. The specification for that format is (mostly) documented in the manual, but it didn’t catch on.
I wrote a quick parser that can convert it to JSON, so now you can use modern tools like jq to manipulate and transform the data however you wish.
And so on, there are more examples in the README. If you can exchange data with other apps, you can now use stfjson to generate the correct format.
You can automate exports, Agenda has “Special Actions” in the category options. Alternatively, if it’s just a one off or for a macro, you can use the Transfer > Export command.
Commands
In DOSEMU, the UNIX command will invoke a shell command on the host.
C:\>unix uname
Linux
If there is a commandline tool that will import data, e.g. a TaskWarrior user might use task add drop off laundry at dry cleaners, then you can create a macro in Agenda that simply launches that command.
You can use something like {F10}ULUNIX task {TYPE;%TASKTEXT}.
Import
Surprisingly, Agenda supports importing arbitrary text data. One of the manuals that came with agenda was Working with Definition Files, which explains how to write a configuration file that allow Agenda to parse anything.
It even has a Regular Expression tutorial, pretty impressive for a 1980s consumer product.
I quite like Agenda. It does many things well, but it’s absolutely true you could replicate most of it’s functionality with modern tools. However, I do enjoy using it, and I’m a big enough nerd that I quite like the challenge of using retro software.
I think the closest modern equivalent to Agenda would be taskwiki. It’s not a perfect match, but if you liked some of what you saw here but are not interested in retro software, try it out!
I’m still using Agenda after two weeks, and about 40% of the way through the manual 😂
