Built for General Motors
Technical Products Group built the ATEC EPROM Programmer for Allison Transmission — first as a DOS system in 2006, then re-written as ATEC '07 in C# on Windows XP / Vista with the exact same operator menu so production-floor staff didn't have to retrain. The application drove two DataIO 3980 EPROM programmers and two Intermec PF2i thermal label printers in parallel over RS-232, burning firmware and printing barcoded serial-number labels for the controller assembly line.
Inside the production app
Production-floor operators wanted the same five keystrokes they'd used on the DOS-based ATEC for over a decade. ATEC '07 preserved that exact menu structure — Convert / Load / Program / Print / Burn / Select / End — and added a Windows menu bar for IT staff and diagnostic workflows. Hardware status, current settings, and a session-long Event History sat on one screen so a line lead could see at a glance whether both programmers and both printers were online before the next part arrived.
The production-floor stack
ATEC '07 didn't try to look modern; it tried to be invisible. The DOS predecessor had been running the same menu for a decade by the time the C# re-write landed, and the operators owned that muscle memory. The application kept the muscle memory, modernized everything underneath, and added the diagnostic surface IT had been asking for the whole time.
Industry-standard production EPROM programmer from Data I/O Corporation. Two units, RS-232 control, dual-socket simultaneous burn. ATEC drove them via the documented DataIO Remote Control protocol with packet-checksum validation on every command.
The application burned the actual EPROM modules that became transmission-controller firmware on the Allison line. Each socketed device received an address-translated Motorola S-Record image, the burn was checksum-verified end-to-end, and a barcoded serial-number label tied the chip to its source firmware in the Event History.
EasyCoder PF2i (Intermec, now Honeywell) thermal label printers, RS-232 controlled. Two units running in parallel, printing barcoded serial-number + part-number labels for the Allison transmission-controller assembly line.
Engineering produced firmware in Intel HEX format; the DataIO 3980 wanted Motorola S-Record (S11 / S19). ATEC ran the format conversion on every file load, address-translated and checksum-validated, with the result captured in the Event History.
Microsoft Visual Studio, native .NET WinForms, no third-party UI toolkit. Designed to operate full-screen at 1440×900 on the production-floor flat panels. Settings persisted to an XML configuration file alongside the executable.
Every operator action, every hardware event, every checksum-mismatch landed in a session-long Event History on the main screen and a rolling text log on disk. Production QA could reconstruct any controller's firmware lineage from the log if a unit came back from the field.
A production case study
From the DOS-based ATEC system in 2006 through the ATEC '07 C# re-write that shipped under Windows XP and Vista, the same application architecture moved EPROMs through Allison Transmission's production line — two DataIO 3980 programmers, two Intermec PF2i printers, full RS-232 plumbing, and a keyboard-first operator UI that the line never had to retrain on.
Why this case study matters
ATEC '07 was designed for a line worker with greasy gloves and the next part already in their hand. The Main Menu accepted single-digit keyboard shortcuts; the Hardware Status panel told the operator at a glance whether the rig was ready; the Event History caught every action so QA could trace any controller back to its burn. The Windows menu bar existed for IT, not for the line — the line never needed it.
The DOS-based ATEC had been running the same operator menu for a decade by the time the C# re-write landed. The new ATEC '07 preserved the exact menu — same numbering, same wording, same flow — so the operators didn't lose a single day of throughput to retraining. Underneath, the WinForms re-write modernized the hardware drivers, the diagnostic surface, and the logging in ways the DOS app never could.
Every EPROM the line shipped carried a barcoded serial number printed on a thermal label, tied through the Event History to the source firmware file, the checksum, and the burn timestamp. When a controller came back from the field, QA could rebuild the lineage from the log on disk. That same discipline carries forward in A1SI's current 21 CFR Part 11 audit-trail work on CVWS, EMDT, and TERM.
If your line needs an operator UI that engineers won't have to apologize for — keyboard-first, hardware-aware, diagnostic-friendly — A1SI's been doing this since 1997. Modern stacks now (C# / .NET, Python, React Native), same engineering discipline. Tell us about your line.
