ROMX is an in-system programmable device that replaces the system ROM’s (D0-F8) and optionally, the Video ROM in your Apple II or II Plus computer. 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 ROMX firmware) is updateable in-system.

What do we mean by In-System Programmable? This simply means that you can re-program ROMX 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 ROMX boot menu, or by running the ROMX.DISK utility from the ROMX floppy disk image. The firmware image is also upgradeable using the same process.

The optional ROMX video ROM with ROM-Link cable has 16 text ROMs (fonts) that can be selected from the ROMX menu or also associated with a specific system ROM. The ROMX is preloaded with a number of ROM images including basic diagnostics.

Hardware Requirements: ROMX will work in any Apple II but its functionality may be limited by the amount of RAM in the machine. You get full functionality in machines that have at least 32K of RAM. With less RAM, you can install a pre-configured board into a machine with as little as 4K but you will only get a simplified menu that lets you switch banks. The board can be pre-configured (images loaded, defaults set ,etc.) in another Apple II with 32K or more.

Comes as pictured, with ROMX system ROM adapter. Video ROM adapter with connection cable sold separately. Replaces “93-Series” ROMs. For reproduction “27-Series” motherboard see the simple to install DIP Plug option. You can read about the DIP Plug option on our Wiki (see below).

Accessories:
For Apple II/II+ with 93-Series ROMs, no extras are needed.
For Apple II clones with 27-Series ROMs (RM version) you can add the DIP plug option.
For the optional Text ROM board (Rev 7 motherboards and higher), order the 2316B SPCL Video ROM.
For the optional Text ROM board (pre-Rev 7 motherboards), order the 2513 Special Video ROM set.

NOTE: ROMX will also work with many Apple II clones. See https://theromexchange.com/documentation/romx for more information or contact support@jdmicro.com.
The ROMX DOES work with the 27-series II Plus motherboard from ReActiveMicro. You can add a jumper to H11 Pin8-9, or order the “27-Series” version of the ROMX to have a DIP Plug included which you can add simply to your 27-series board. TheROMExchange did a blog about the fix here: https://theromexchange.com/blog/2nd-march-2021
