Building a Classic Mac Support Server

Posted on by

If you’re a classic Mac enthusiast, you know that it’s sometimes difficult to enjoy if you don’t have the right tools. Things like the choosing the right system software, the right version(s) of Stuffit Expander, and so forth. Then, getting that software to the machine can be a challenge. Floppy disks are problematic for a number of reasons. Using AppleTalk to connect your classic Mac to a modern network if challenging as support was removed years ago from MacOS X.

Luckily for us, there’s a great pre-made installation called “MacIPRpi” for Raspberry Pi. It delivers a suite of tools that are already configured and ready to use. I’ve used it for a couple of years and it’s worked great. For most folks, this will serve you well!

However, recently I’ve attempted to do certain things it couldn’t handle. This is mainly due to netatalk being updated since the image was created. This blog post contains my notes as I set out to create a newly updated version of this suite of tools from scratch.

This blog post is a repair thread from social media that began on February 24, 2018.

So, this happened. My latest retro delivery. Any guesses?

It is, yet, another plotter. An HP 7585B wide format plotter with a 36” wide paper path.

Unfortunately it failed the first power on test and now it smells bad. So it’s been taken to bits to find the culprit.

Hayes Please: Preserving Software History

Posted on by

Hayes is best known for modems and for establishing the ubiquitous AT command set as the standard for all modems that followed. Their external modems, made of aluminum, fronted with jewel-like LED status lights were the top shelf of modems. As a kid, Hayes modems were a status symbol. Hayes also made other hardware products like the Chronograph, Transet, and InterBridge all with the same footprint designed to stack on one another– the “Hayes Stack” was a brief marketing campaign.

Say… please button from the Computer History Museum catalog.

While you may be familiar with Smartcom, the series of terminal programs for their Smartmodems, you may be surprised to learn that Hayes also created a database application.

What follows is my journey over several months in 2021 in researching, salvaging, repairing, and archiving an unknown piece of computing history.

Macintosh Emulation and Printing using Mini VMac on a PocketCHIP

Posted on by

Alternate title: I want to print from an emulated Mac on a pocket computer to my ImageWriter II over AppleTalk.

The PocketCHIP that wants to be a Mac. Yes, that’s a pencil sticking through the pencil holder being used as a stand. The hole on the left is for a pen (it’s round). Clever, yes?

I’ve had a PocketCHIP for several years now. I picked it up right after the Kickstarter campaign was finished sometime in 2016/2017. It’s a great little Linux-based handheld device that combines a lot in one package (touch display, keyboard, storage, battery, sound, USB port, WiFi, Bluetooth, etc.). The novelty wore off and I stowed it away in a box. The company Next Thing Co. went out of business shortly thereafter in March 2018.

Self Referential Pen Plotter Floppy Disks

Posted on by

In November 2021, I posted a short video on Twitter of my Roland DXY 1150 pen plotter drawing a generative wobbly circle design on top of a 5.25″ floppy disk. A few people responded that they would buy one of the floppies. This got me thinking about the medium of a floppy disk that I was using.
