DATA GENERAL Product Lines We Repair
Our engineers are trained on the full DATA GENERAL product range. Below are the major product families we service.
Nova Series Minicomputers
16-bit minicomputers widely deployed in process control and data acquisition. Nova systems suffer from capacitor degradation, power supply failures, and core memory intermittency. Synchronics performs board-level repair, capacitor replacement, and memory diagnostics to restore Nova reliability.
Eclipse Series Processors
32-bit virtual memory processors used in advanced control and networking applications. Eclipse boards experience CPU failures, cache degradation, and bus controller issues. Our technicians perform microcode updates, board repair, and full system validation.
Data General I/O Modules and Peripherals
Analog and digital I/O cards, parallel controllers, and interface modules critical for sensor integration and instrumentation. Common faults include relay failures, analog amplifier drift, and optocoupler burnout. Synchronics replaces failed components and recalibrates analog channels.
Dasher Terminal Systems
CRT and graphics terminals used for operator interfaces and system monitoring in control rooms. Failures include CRT degradation, keyboard controller faults, and video amplifier issues. Synchronics restores Dasher terminals or provides suitable industrial replacements.
Mass Storage Systems
Disk drives, tape cartridge systems, and storage controllers used for data logging and program backup. Common issues include head crashes, servo mechanism wear, and controller card failures. We perform data recovery, head replacement, and servo recalibration.
Why Choose Synchronics for DATA GENERAL Repairs?

Standard 7–10 working days. Express 3–5 days available for critical breakdowns. Emergency same-day/next-day service for unplanned downtime.
6-Month Warranty
Every repaired unit ships with a 6-month comprehensive warranty on parts and labour. Our repair success rate is over 94% across all brands.
All-India Service
Couriered repairs accepted from any city in India. Doorstep pickup available in Vadodara, Mumbai, Pune, Ahmedabad, Surat, Chennai, and more.
Common DATA GENERAL Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in DATA GENERAL equipment arriving at our workshop.
- ✓Nova core memory intermittent read failures — Magnetic core arrays degrade over 40+ years due to material fatigue and thermal cycling. Sense lines develop open circuits or crosstalk causing unpredictable data corruption.
- ✓Power supply capacitor venting and voltage regulation loss — Electrolytic capacitors in Data General power supplies dry out and fail after decades of operation, causing ripple voltage spikes and supply dropout. Common in both Nova and Eclipse systems.
- ✓Eclipse CPU address decoder faults and bus parity errors — Address decoding logic on Eclipse processors accumulates timing violations due to chip degradation. Parity check failures indicate single-bit errors in microinstruction sequencing or memory access timing.
- ✓I/O module analog channel calibration drift and amplifier failure — Operational amplifiers in analog I/O modules develop input offset drift and gain errors. Precision resistor networks lose tolerance over time, causing sensor readings to deviate from actual values.
- ✓Dasher terminal CRT focus and brightness loss — CRT cathode emission degrades naturally over 30+ years. High-voltage (anode) circuits develop component failures, reducing electron beam intensity and display contrast.
- ✓Disk drive head crash and servo system malfunction — Mechanical wear in spindle bearings and actuator arms combined with head-media contact causes data loss. Servo feedback loops fail due to sensor aging or amplifier degradation, preventing track-following.

Frequently Asked Questions — DATA GENERAL Repairs
Do you repair Data General equipment anywhere in India?+
Yes. Synchronics repairs the full Data General product range — Nova and Eclipse minicomputers, I/O modules, terminal systems, and mass storage peripherals. We offer PAN India door pickup from Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Bangalore, and all other major industrial cities. All repairs are completed at our Vadodara, Gujarat facility.
Data General stopped manufacturing in 2001. Can you still service my Nova/Eclipse system?+
Absolutely. Thousands of Data General systems operate reliably across Indian plants today. Our engineers possess deep firmware and hardware knowledge accumulated over decades. We perform component-level repair, source equivalent replacement parts, and validate systems using authentic Data General diagnostics. Many plants rely on Synchronics to maintain their Data General systems cost-effectively during multi-year modernization roadmaps.
What is your turnaround time for Data General minicomputer repair?+
Most Data General repairs are completed within 10-14 days. Complex failures (disk controller rebuilds, memory system replacement) may require 3-4 weeks. We provide free diagnostic evaluation and timeline estimate before work begins. Emergency turnaround is available for critical systems at premium rates.
Can you recover data from a failed Data General disk drive or tape system?+
Yes. Synchronics performs data recovery on Data General 6031 disk drives and cartridge tape systems. We have clean-room facilities for head replacement and servo diagnostics. Recovery success depends on damage severity; we provide honest assessment and transparent pricing before attempting recovery.
My Data General system shows fault codes like MEMORY PARITY ERROR or BUS TIMEOUT. What does this mean?+
MEMORY PARITY ERROR indicates single-bit corruption in core memory (Nova) or DRAM (Eclipse), often from failing capacitors or memory plane degradation. BUS TIMEOUT suggests the CPU cannot complete memory or I/O transactions within timeout limits, pointing to address decoder faults or controller card failures. Synchronics diagnoses root causes using comprehensive test protocols and recommends repair or component replacement based on cost-benefit analysis for your plant.
How do I send my DATA GENERAL unit for repair?+
Pack the unit securely and courier it to our Vadodara workshop. Include a note with the fault description and your contact details. We will log it into our system and WhatsApp you a job number within 24 hours of receipt. Doorstep pickup is available in Vadodara, Ahmedabad, Surat, Mumbai, and Pune.
What is the cost of repairing a DATA GENERAL drive or PLC?+
Repair cost depends on the model and the fault. We offer a free diagnosis — once we identify the fault, we provide a fixed quotation before proceeding. Typical repairs cost 20–40% of the new unit price. We will never repair without your approval.
What warranty do you provide on DATA GENERAL repairs?+
All repaired units carry a 6-month comprehensive warranty covering the same fault and related issues. If the fault recurs within the warranty period, we repair it free of cost.
Do you provide a no-fix, no-fee guarantee?+
Yes. If we cannot repair your DATA GENERAL unit after diagnosis, you pay only the diagnosis fee (₹500–₹1,500 depending on the product). The unit is returned to you at no additional charge.
