Earl Weaver Baseball — the manager is in the code Runs here
1988 · Eddie Dombrower / Electronic Arts · System 7 · Mini vMac (Mac SE) · 512×342 black and white
Guide updated September 2026
The selling point was that Earl Weaver, who had just finished managing the Baltimore Orioles, sat down with the developers and specified how the computer manager should think — when to pull a pitcher, when to pinch hit, when the percentages say bunt. You can play the games or you can sit in the dugout and let the simulation run, and the second mode is the one the game was built for.
The field is drawn in perspective from behind home plate, the camera follows the ball, and the scoreboard keeps a real box score. For 1988 it was the most credible baseball simulation on a personal computer.
Boots to the ballpark. Use the Play Ball! menu to start a game, and Commissioner to set up teams and seasons.
Controls
| Mouse | Pitch, swing, and field |
| Play Ball! menu | Start a game; choose manual or managed play |

Electronic Arts owns it and still exists, and the game is built on a licence of Earl Weaver's name from the 1980s. No current product contains this Macintosh build and it has not been sold in decades.

How it works & what to expect
| Machine | Macintosh SE, 512×342, black and white |
|---|---|
| System | System 7.5.3 — this floppy carried no System of its own |
| Emulator | Mini vMac, compiled to WebAssembly |
| Saves | Seasons and rosters save inside the emulated Mac |
The disk this was built from has no System on it, so unlike most of the 68k catalogue here it is served on a System 7.5.3 boot disk rather than its own. That is why it comes up to a desktop for a moment before the game opens.
The commercially sold team and stadium disks EA published separately are not included; this is the base game.
Why it is remembered
The managerial AI was the product. Sports games before it simulated the physical game. Earl Weaver Baseball simulated the decisions, using rules an actual major-league manager dictated, and that is why it is still cited in writing about sports simulation.
It kept real statistics. Box scores, season stats, a league that persisted. That is now standard; in 1987 it was the reason people bought it.
Eddie Dombrower had form. He had already made a computer baseball game for the Intellivision and went on to work on the Odyssey of the Mind and other simulation work; Earl Weaver Baseball is the one that made the approach mainstream.
Getting started
Watch a managed game first. Set both teams to be run by the computer and let an inning play out; it is the quickest way to see what the simulation is actually doing.
When you take over, take over the batting only. Fielding and pitching both have their own controls and learning all three at once in black and white is more than the game needs from you.
The Commissioner menu is where the depth is. Rosters, line-ups and season settings are all editable, and a season played out against the computer manager is the intended long game.
Questions people ask
Did Earl Weaver actually work on it?
Yes. He specified the managerial logic — the decisions the computer manager makes — which was the game's main selling point.
Are the extra team and stadium disks included?
No. EA sold those separately and they are not part of this disk.
Can the computer play both sides?
Yes, and watching it do so is the best demonstration of what the simulation is for.
Can I save a season?
Yes — seasons and rosters save inside the emulated Macintosh in your browser.
Why does it show a desktop first?
This floppy carried no System of its own, so it is served on a System 7.5.3 boot disk. Most 68k titles here boot straight into the game instead.
Is it in colour?
No. This is the black-and-white Macintosh release.
