Core expertise
Legacy modernization
instead of replacement.
When a line is at risk, parts are obsolete, or the OEM recommends replacing the whole machine, you need more than a repair quote. We analyze the technical root cause, document the options, and give you a defensible retrofit decision for maintenance, budget, and management.
From symptom to decision
Four operational situations where retrofit beats replacement
Replace legacy languages
Situation & pressure
The machine still runs, but control code in Pascal, assembler, or legacy C is no longer maintainable. Source code or internal know-how is missing, and maintenance cannot approve changes safely. Controller replacement: €150,000–500,000.
Technical path
We reconstruct the logic, document behavior and risks, and move the control code to modern C++, Python, or TypeScript — on your existing hardware.
Decision-ready outcome
You get a defensible retrofit decision: what changes, what stays, and why full controller replacement is not required.

Typical ROI: < 12 months
Firmware upgrade without hardware replacement
Situation & pressure
Legacy firmware has known CVEs, no vendor patches, and no sustainable update path. Maintenance owns the security and uptime risk; the typical recommendation is hardware replacement for €50,000–200,000.
Technical path
Firmware reverse engineering: we analyze the boot chain, flash memory map, and device protocols, then rebuild secure, maintainable firmware with signed OTA updates and rollback support.
Decision-ready outcome
You can explain internally how uptime and security improve without replacing the existing hardware.
Cost savings

New purchase (replacement)
€ 50,000 – 200,000
Solvetronix
€ 8,000 – 30,000
You save
up to € 170,000
Savings
up to 85%
Typical ROI: < 8 months
Replace EOL components (drop‑in)
Situation & pressure
A core IC is end‑of‑life, spare parts are discontinued or cost €5,000+ each. If it fails, production stops, and pressure builds to approve a new machine budget.
Technical path
PCB reverse engineering: we reconstruct the schematic, characterize the EOL chip, select a modern drop‑in replacement, and update the PCB layout.
Decision-ready outcome
You get a documented obsolescence-management option with cost, risk, and implementation path instead of a blanket replacement request.
Cost savings
Direct comparison
New purchase (replacement)
€ 100,000+
Solvetronix
€ 5,000 – 25,000
You save
up to € 95,000
Savings
up to 80%
Typical ROI: immediate
Legacy protocol bridge
Situation & pressure
New MES/SCADA software can’t talk to the old machine. Source code, protocol documentation, or vendor know-how is lost; the OEM or integrator recommends replacement for €200,000–2,000,000.
Technical path
Passive protocol reverse engineering of serial/bus traffic. We reconstruct behavior from traffic and the machine itself, then build a bridge that translates proprietary protocols into MQTT/REST/OPC‑UA.
Decision-ready outcome
You get a defensible interface decision: MES/SCADA integration works, the machine stays in service, and replacement need is technically documented.
Cost savings
Direct comparison
New purchase (replacement)
€ 200,000 – 2M
Solvetronix
€ 15,000 – 50,000

Typical ROI: < 6 months
