ROMXc is an in-system programmable device that replaces the MONROM and your Video ROM in your Apple IIc (IIc Plus version coming soon – this DOES NOT work in the IIc Plus). It stores up to 15 ROM images, and presents them for selection via an on-screen menu system. In addition, the menu system itself (the ROMXc firmware) is updateable in-system. The ROMXc comes standard with an on-board clock (backup battery included).

What do we mean by In-System Programmable? This simply means that you can re-program ROMXc with your own ROM images and updates without removing the device from your computer, and without need for an external IC Programmer. Uploading of new ROM images is done through either the ROMXc boot menu, or by running the ROMX.DISK utility from the ROMXc floppy disk image. The firmware image is also upgradeable using the same process.

The ROMXc video ROM with ROM-Link cable (included) has 32 text ROMs (fonts) that can be selected from the ROMXc menu also, or associated with a specific system ROM. 16 fonts are software selectable from two banks, and banks are selected by the //c Keyboard switch. The large 32K banks can also hold DOS, ProDOS, and complete programs for instant loading on power up. The ROMXc is preloaded with a number of ROM images including basic diagnostics.

Hardware Requirements: ROMXc will work in any Apple IIc. Does NOT work in the IIc Plus.

Software and manual can be found from The ROM Exchange:
