ROMX ROM Images

DEADTEST.dsk Adrian Black's (Adrian's Digital Basement) Dead Test ROM. This tool runs from ROM and executes a March-U test which can find some errors that simpler RAM tests miss.

ROMX Factory Images : .ZIP file containing the stock ROMX images in case you need to restore any of them. All the images are numbered as per the stock bank number, and all are .RMX format with the factory description and INFO text.

COLDSTART.zip This dsk file contains images for both the ROMX+ and the original ROMX. It provides a cold start function by simply pressing ctrl-reset twice in rapid succession. It also has a checksum byte to satisfy some ROM diagnostics and software checks. This can replace the standard Applesoft image on your ROMX or ROMX+ or it can also be used to roll your own F8 EPROM image for your Apple II+ or clone.

KIOSK MODE.zip : (APPLESOFT BASIC KIOSK.RMX is contained within the disk image). This is a Kiosk Mode ROM which forces a cold start when the reset key is pressed. Useful for display machines to prevent people from stopping program execution via reset (with this ROM, if they press the reset key the machine will reboot from the floppy drive and re-load the demo application rather than breaking out to Applesoft or monitor etc). Also useful if you want them to be able to swap out floppy disks but don't want them having to flip the power switch to reboot - just press Reset (or control+reset depending on the keyboard switch setting).

APPLESOFT W_SMARTPORT FIX.zip (RMX ROM image with CiderPress files attributes tags)

SMARTPORT F8 MOD.zip (Disk Image)

This ROM image is identical to the standard Applesoft Autostart ROM except for two bytes. By changing the byte in the drive slot search routine at $FABB from $07 to $05, the Autostart ROM will find "SmartPort" devices that only match the first 3 of the usual 4 ID bytes that identify a bootable device. The MicroDrive/Turbo card from ReActiveMicro.com is such a device. With a standard Apple II or II+ you can only boot this card by typing PR#n, but this patched Image in the ROMX, the computer will find and boot the MicroDrive/Turbo automatically (assuming it's in the highest numbered slot). The second byte changed is the ROM checksum byte - restoring the checksum allows diagnostic programs to successfully check the ROM and also prevents some games from detecting a modified ROM which causes them not to run.

MEMTST V14RX RMX.zip (RMX ROM image with CiderPress files attributes tags)

MEMTST v1.4RX.dsk.zip (Disk Image)

This is a version of Andrew and Ivan Hogan's APPLE II RAM TEST UTILITY v1.4 that has been modified to work with ROMX. You can get details of this program here.

The main differences with our version is that it will run with as little as 16K and will identify/test all RAM sizes from 16K-64K as well as any Saturn 128K compatible memory. It will also test memory banks that are faulty due to bad RAM or logic chips which would otherwise prevent them from even being recognized. Although the extensive help screens had to be removed, it should be fairly intuitive. You can use the + and - keys to have tests loop for up to 100 times or Infinitely. Or use the Group keys to select one particular area of memory to exercise. One "hidden" command is CTRL-A which will check all memory including bank-switched-RAM (BSR) even if the program has not recognized that those banks exist.

DOS Images

ROMX DOS images can be uploaded into a ROM slot, and associated with a system ROM using &Dn, where n is the bank number of the DOS image. See blog post here.

DOUBLEDOS.RMX Also known as DubbleDOS. More information here

DOS 3.3 FAST + LINK.RMX Here's a nifty DOS image. If you link another image to this one, it will load DOS 3.3 along with it. If you edit the description of THIS image to include the usual &Dn command, it will also load THAT image into the Language Card. For example, if you point the DOS image to an Integer BASIC image you can have a machine that comes up with DOS already loaded as well as Integer in the Language Card! NOTE: The tertiary image gets loaded verbatim into the Language Card, so only certain images like INTBASIC or FPBASIC would be useful here. If you set the BootDelay to 0 then this link will not work. Give it a try!
