System Compatibility
| System | Compatibility |
|---|---|
| GE Mark IV Turbine Control | ✅ Native / Primary Platform |
| GE Mark IV+ (enhanced) | ✅ Compatible (verify revision) |
| GE Mark V | ⚠ Not directly compatible — different architecture |
| GE Mark VI / VIe | ❌ Incompatible — requires platform migration |
| Third-party Mark IV equivalents | ⚠ Case-by-case — contact Konmask technical support |
Selection Guide
Use the following decision framework to select the correct microprocessor board for your Mark IV system:
- Confirm your system generation: Locate the Mark IV cabinet nameplate and identify the system revision (e.g., Mark IV, Mark IV+).
- Record the existing board part number: The full suffix (e.g., 1J1J) encodes hardware revision — do not substitute without matching this.
- Check firmware version: Obtain the current PROM/EPROM version from your control system documentation before ordering a replacement.
- Assess condition requirement: Choose OEM New for greenfield or critical spares; Refurbished/Tested Exchange for budget-sensitive MRO.
- Verify lead time vs. urgency: Konmask.com maintains ready stock for common revisions — contact us for availability on specific suffix variants.
Quality Assurance & Sourcing
- Source Verification: All units sourced from decommissioned OEM systems, authorized distributors, or certified refurbishers.
- Functional Testing: Each board undergoes power-on, communication bus, and I/O channel verification prior to shipment.
- Anti-Counterfeit Inspection: Component markings, PCB layer count, and IC date codes verified against OEM reference samples.

Replacement & Compatibility FAQ
Q: Can DS3800HMPK1J1J replace DS3800HMPK1H1H directly?
A: In most Mark IV configurations, yes — however, the hardware revision suffix difference (1H vs. 1J) may affect firmware compatibility. We recommend verifying EPROM versions before installation.
Q: Is a refurbished unit suitable for a critical turbine application?
A: Yes, provided the unit has passed full functional testing and is covered by a warranty. Konmask.com provides test reports for all refurbished boards. For tier-1 critical spares, we recommend OEM New condition.
Q: How long does delivery take?
A: In-stock units ship within 1–3 business days. Emergency same-day dispatch is available for confirmed outage situations — contact our team directly.
Q: Do you provide installation support?
A: Konmask.com provides pre-installation technical consultation, including compatibility verification and installation checklist. On-site support is available through our partner network.
Q: Can I return the board if it is not compatible?
A: Yes. We offer a 30-day return policy for unused, uninstalled boards. Boards that have been installed are covered under the 12-month warranty for defects.
