Classic Mac OS was prized for its clean, accessible GUI when it first hit the scene in the 1980s. Back then, developers hadn’t even conceived of all the weird gewgaws that would eventually be shoehorned into modern operating systems, least of all AI agents that seem to be permeating everything these days. And yet! [SeanFDZ] found a way to cram Claude or other AI agents into the vintage Mac world.
The result of [Sean]’s work is AgentBridge, a tool for interfacing modern AI agents with vintage Mac OS (7-9). AgentBridge itself runs as an application within Mac OS. It works by reading and writing text files in a shared folder which can also be accessed by Claude or whichever AI agent is in use. AgentBridge takes commands from its “inbox”, executes them via the Mac Toolbox, and then writes outputs to its “outbox” where they can be picked up and processed by the AI agent. The specifics of how the shared folder work are up to you—you can use a network share, a shared folder in an emulation environment, or just about any other setup that lets the AI agent and AgentBridge access the same folder.
It’s hard to imagine any mainstream use cases for having a fleet of AI-controlled Macintosh SE/30s. Still, that doesn’t mean we don’t find the concept hilarious. Meanwhile, have you considered the prospect of artificial intelligence running on the Commodore 64?
Perhaps to the masses, but…
One of the problems with the early Macs were that they were not easily accessible to the blind.
Bear in mind, back in 1984 most home/small-business computing was done on either the 8-bit machines like Apple and Commodore or the IBM PC and its clones running CPM or DOS. Most mainframe or minicomputer work was done using text-based terminals.
Valid point, indeed. 🙂👍 On other hand, before the serial terminal, computers had panels with lights, toggle switches and punch cards or punch stripes.
For programming, at very least. Output happened on teletype printers already, I think.
Then there were the early 1970s hobbyist computers that did use
ASCII keyboards and a text-generator for output on a video monitor or b/w TV set.
They couldn’t be interfaced to a serial connection so easily (because of being directly interfaced to computer i/o address space).
Unless they were combined to form a separate serial terminal hooked up to a serial connection, of course.
In CP/M terminology, these directly wired consoles were called “CRT devices”, I believe.
They were not easily accessible to the blind, either, because no serial data was used for i/o, so no Braille reader or speech synthesizer could be wired in parallel of a serial device.
Making them work would have required to send ASCII to a serial port or integrate special support into application or OS, I assume.
This is very true. It inspired other graphical environments such as GEM or Amiga Workbench.
There’s an revent article that basically says how System 7 was peak in this regards.
(In 1992 to 1995, when the HIG were written, that was the current “MacOS”.)

In 1981 IBM released 32-bit x86 PC meanwhile Macs had relatively primitive 8-bit 6502 that was used in NES for running Super Mario Bros or Duck Hunt, not Doom, Duke Nukem or later Quake, Thief or Half Life (when 3D accelerators become available). It’s like comparing M134 Minigun firing 7,62×51 to Rohm RG-14 revolver firing .22 LR. You can beat a clogged toilet with a baseball bat, but you won’t make it work again if the clog is down the line – first, beacuse the ceramic is all shattered, second, because sewage (8-bit) needs a bigger pipe (32-bit) to flow efficiently.
Umm, what?
Do you mean the Apple ][, which was not a Mac, and was released ca 1977, or do you mean that that Macs had 32-bit Motorola 68000 CPU’s vs the IBM’s 16-bit 8088?
If you’re going to froth at the mouth for no reason at least get your facts straight.
Hi! To my understanding IBM’s PC 5150 used an i8088 and was an 8-Bit PC from an hw engineer’s point of view.
At 4,77 MHz, the 8-Bit 8088 performed worse than an 1 MHz 6510.
That was because instructions needed more cycles etc.
Anyway, the Z80 ruled and was superior to both of them! 😁
That being said, in 1985, the then-new fully 32-Bit 80386 processor was superior to the contemporary 68000 used in Mac/Amiga/Atari ST.
So a Compaq Deskpro 386 from mid-80s did indeed beat them all!
It was a tool for professionals, though, rather than a PC for gamers.
Still, it made MS Flight Simulator ot Accolade Test Drive, Ford Simulator, Sierra’s 3-D Helicopter Simulator, Interphase etc run smoothly! 😃
Beginning with release of EGA graphics in 1984, the PC started to challenge the home computers.
It could do 640×350 pixels in 16/64 colors in best cases.
Super EGA clones that appeared in 1985/1986 could do 800×600 pixels, even!
Unfortunately, games on all platforms still were stuck in about 320×200 pixel res most of time.
A few EGA games of the 80s used 640×200, at least, though.
The extra resolution was useful to display instruments in flight sims, for example. Such as Falcon A.T.
EGATrek and CD Man of late 80s used 640×350 pix resolution, most prominently.
80386 didn’t really hit the market in a PC until late 1986 and was really up against the 68020 released in 1984 and used in the Macintosh II released early 1987.
+1
I think the 68020 wasn’t really used as a stock processor, though. Except for the Macintosh II, I think.
The Atari ST didn’t get it officially before the 90s (but third-party PAK-68 board from c’t magazin was available summer ’87)
and in late 80s it was still an option for the Amiga 2000 (’87, had CPU upgrade slot from the get go).
By comparison, Windows/386 and 386 ATs were available by ’87/’88.
So there was an actual use case of the 386 early on, at the very least.
It also caused quite a performance boost when running plain 8086 software and if being paired with 32-Bit wide memory.
PC-MOS/386, Xenix 386 and AutoCAD 386 were available in late 80s, too, I think.
Wow they managed to put a piece of software that talks to the internet on an old computer, amazing. You can POST and GET, splendid. AI is not “running” on these old machines, it’s just another web portal.
One of the things I am delighted about by old machines is the lack of modern BS infesting them. Apple Intelligence isn’t coming to my iMac G3, and I like it that way. Yet everywhere I turn these slop-coded infractions are being promoted at all corners for them. I don’t get the reason, what does adding hallucinating maybe-accurate probably-not glorified markov chains actually add to this? Yes, they sometimes can assist with programming, especially Clod, but are you really learning anything with this? Several of these projects, you watch their creators posting on forums and they seem confused by “their” own software.
Hi! The Atari ST platform (TOS) had a third-party web browser and some TCP/IP stack, too:
Crystal Atari Browser (CAB) and STinG/STiK. There also was Draconis bundle.
iCab on Mac is related to older CAB.

Btw, it’s also possible to get an dinosaur such as IBM PC 5150 on the internet.
All it needs is a NIC that’s 8-Bit slot compatible and a simple packet driver (there’s an NE2000 driver that uses 8086 instructions).
Then it needs internet software, too, of course.
Links, Lynx, Doslynx or Minuet can run in text-mode, for example.
They have built-in TCP/IP stack, if I remember correctly.
The newest one is Microweb, but it may need mTCP.

Last but not least, there’s also an early prototype of a web browser for PC GEM..
It needs a SLIP connection, though and isn’t so easily to be configured.
I’ve once seen a screenshot of it years ago on a personal webpage.
I just recently started getting back into using classic Mac OS 7 on a regular basis, and reading this article, just… no. If others want to stuff up their machines with “agentic AI”, that’s fine but leave me out of it. And I didn’t go back just for nostalgic purposes either. Other people are doing the same; looking to the older stuff because they don’t want to be railroaded forward into “You will own nothing and be happy”ville.
