ℒӱḏɩę 💾☮∞🎶♲☀🔋IBM CGA CRT with interesting burn - ERROR H on boot, with IBM logo burned in and color bars at the bottom. XT didn't have an IBM logo on boot, so this looks like it was used with a PCJr - it's boot screen is the same.
What amazes me is this PC sat there errored out for so long the CRT burnt. WTF 😆
Jim Patterson 🇨🇦@amiserabilist @MAJ1 Those #IBM lobbyists are wizards at selling junk systems to governments, it seems. After all, it's IBM - what could go wrong?
The Canadian government is in the process of replacing their #Phoenix pay system that IBM developed with a new one called #Dayforce. There's currently a backlog 233,000 transactions needing correction. Many relate to public servants not being paid or being overpaid. Our Auditor General has warned that they need to be resolved before transferring the data into Dayforce, still years away.

Auditor general flags potential risks in transition from Phoenix to Dayforce | CBC News
The federal government is on pace to replace its troubled Phoenix pay system with a new platform, but risks including a backlog and rising costs remain, according to a report tabled Monday by Auditor General Karen Hogan.

GripNews🌘 IBM 4 Pi 航太電腦的興衰史：圖解編年史
➤ 從 Skylab 到太空梭：揭開冷戰時期軍規電腦的技術面紗
✤ https://www.righto.com/2026/03/ibm-4-pi-computer-history.html
本文探討了 IBM 於 1967 年推出的 System/4 Pi 系列電腦。這套專為航空電子與航太領域打造的系統，名稱源自立體角的完整球體（4π），象徵其能涵蓋從飛行器到導彈控制等廣泛的應用需求。文中細述了該系列初期型號（TC 與 CP）的架構設計、核心記憶體技術，以及它們在 Skylab 太空站、太空梭及多種軍用飛行器上的關鍵貢獻。透過作者取得的珍貴行銷手冊與歷史資料，這段原本鮮為人知的運算歷史得以重現，揭示了那個時代如何在有限的物理空間內，達成軍用級的高效能運算。
+ 這些 60 年代的工程傑作實在令人讚嘆。在僅有幾 KB 核心記憶體的限制下，居然能支撐起如此複雜的航太任務，現代程式設計師確實該好好研讀這段歷史。
+ 很有趣的文章！我一直對 IBM 的軍用硬體感到好奇，
