I DON'T SHIP TO THE USA AT THE MOMENT. DO NOT PLACE AN ORDER AS I WILL NEED TO CANCEL.There are two versionsavailable on (see my otherlistings): 1.Replacement D0…F8(AppleSoft) + Woz Integer basic and Inspector/Watson2. Replacement D0…F8 (AppleSoft) + Deadtest

This board replaces the 6 original ROMs (D0,D8,E0,E8,F0,F8)on the motherboard containing AppleSoft Basic.

The board is compatible with Apple II, Apple II+, Apple IIEuroplus. (Note it is not compatible with J-Plus)

You get two replacement ROM images, one with exactly the same content as youroriginal 6 ROM’s containing AppleSoft Basic, and another ROM image with theDEADTEST diagnostic program. Deadtestis an extensive DRAM test, more info canbe found if you google "Misterblack Apple II deadtest on github"

The 32Kx8 EPROM on this board contains 2 ROMimages or banks, selectable with a jumper.

The first bank (Jumper ON) contains the exactsame contents as the original Apple ROM’s, five Applesoft BASIC ROMs D000, D800, E000,E800, F000 and the auto start boot ROM F800.

The second bank (Jumper OFF) contains theDeadtest DRAM test. When you boot upthe computer, it start executing this test automatically, and will identify anybad DRAM chips. It gives audio responsewith beeps and also a summary screen that identifies any bad DRAM IC’s.

See the memory map of the Eprom in one of the attachedphotographs.

Thereis free software to create your ROM images available. See the photo’s for the download site for theHxD software. Then follow the two additional photos on how to build yourROM. It is a simple drag and drop of 2Kbytes .bin files. The second to last photo chows this actual ROM build. Thisboard is compatible with, a classic27C256 32Kx8 EPROM or a 27E257 or 27C257EEPROM, so if you don't have a UV eraser, no worries, just use a Flash EEPROM. (see the Photo of these devices)

Installation of the ROM card:

First remove all the six ROM’s from the mother board andalso the IC at location F12.

The board plugs into the D0 socket and also into the socketat location F12 (you have to remove the IC there (74LS138).

There are many detailed documentations on the web availableto assist you. See some links on one ofthe photos.

Take your time to make sure all the pins are aligned beforeputting pressure on the board to seat it.Use a flashlight, small mirror or a good pair of magnification glassesto look at the socket.

WARNING: Theboard will obstruct installation of expansion cards longer than Apple Disk IIcontroller into slot 6 and 7.

One more thing:(where did I hear that before?)

This board has small gold plated pins of only 0.5mm diameterto plug into your Apple II mother board.

These are the thinnest pins available and will not damageyour precious mother board sockets. (see photo)

Some other ROM boards have round 0.6mm pins or square pinsof 0.65mm (normal header pins, like the one on this board for the Jumper).

The EPROM socket is also gold plated, round machined pinsthat are of high quality compared to standard IC sockets. Should you want to remove this EPROM tomodify its contents then you have nothing to worry about.

Please be aware that the software contained onthe Apple II ROMs is still under license by Apple! If you own an original AppleII then you are implicitly licensed to use the software in the ROM of thatmachine.
Under no circumstance should you use any Apple II ROM image if you are notlegally entitled to do so.
