Features:
- Provides a fixed, nonvolatile EPROM program image.
- Offers host-dependent capacity for Series Five CPU or APU500 use.
- Supports disciplined offline erase, program, verify, and label control.
IC655MEM512 avoids battery dependence for the stored program but cannot accept ordinary online changes.
Capacity depends on whether the device serves a CPU or the ASCII/BASIC module, so the host must be recorded with the image.
A correct part number is only half of the replacement: the programmed contents and checksum must also match.

When EPROM is preferred over editable RAM
- Validated image: Use a fixed program after engineering approval.
- Nonvolatile storage: The programmed code does not depend on a backup battery.
- No online edit: Operational changes require a new programming cycle.
- Configuration control: Treat the device label and checksum as part of the release.
Interpreting the memory option correctly
- CPU use: Compatible Series Five CPU service provides 8K.
- APU500 use: The ASCII/BASIC module uses 24K.
- Host identity: Do not move images between roles without validation.
- Program format: CPU ladder and BASIC applications are different artifacts.
Handling the UV EPROM workflow
- Full backup: Save the approved source before erasure.
- UV erase: Use the specified process to clear the device.
- Programming: Load and verify the complete intended image.
- Protection: Store and label programmed devices to prevent mix-ups.
Checks after fitting a programmed device
- Part and host: Confirm model and intended equipment.
- Checksum: Compare with the approved application record.
- Writable data: Restore separate RAM or register values if required.
- Functional test: Run a controlled sequence before production.
