Ubrt2300 Universal Battery Repair Tools [2021] -

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!

For repair shops, the tool provides definitive proof of battery health. You can generate detailed health reports for clients before committing to hardware replacements. Safety Warnings and Best Practices

The software automatically detects the chip type or allows for manual selection. It reads the current design capacity, full charge capacity, cycle count, and manufacture date.

Safety locks triggered by deep discharge or voltage spikes.

The overall degradation level over time.

This comprehensive guide covers how the UBRT2300 works, its core features, and how to use it to service laptop power packs. What is the UBRT2300?

Updates the Full Charge Capacity (FCC) to match actual cell health.

Licenses are sold through the developer's website. However, some users have reported difficulty registering or purchasing licenses online. Alternatives like "Battery EEPROM Works" exist but can be substantially more expensive (e.g., $350).

A specific revision of I2C used heavily in laptop batteries to report charge status and health.

Unlike basic repair tools, the UBRT2300 connects via USB-C to a Windows or Linux PC. The proprietary software (UBRT-Analyzer Pro) displays:

The core function of the UBRt2300 involves two main restoration techniques:

When a technician replaces the internal chemical cells (re-cell process), the gas gauge IC often retains the old data. The device will continue to read the battery as degraded, or worse, refuse to accept it due to cryptographic handshakes or error flags. The UBRT2300 is designed to bridge this gap by communicating directly with the BMS chip to reset these parameters. Core Features of the UBRT2300

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. ubrt2300 universal battery repair tools

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. For repair shops, the tool provides definitive proof

You can download it here, here are some examples.

Print a list of all items.
- $ ./stfjson < transfer.stf | jq '.[].items[].text'
Show all items with a due date.
- $ ./stfjson < transfer.stf | jq '.[].items[] | select(.categories[].name=="\\When")'

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. It reads the current design capacity, full charge

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 😂

Bob Newell’s Agenda Page has lots of old documentation. In particular, I found this old Lotus Support FAQ from 1990 fascinating.
