Roland TR-505 Update Notes:

1. Remove (de-soldere) the old 28-pin ( TC531000AP) IC11 EPROM

2. Insert the new Quad ROMs Adapter KIT and solder the 28 leads on the wiring side.

3. After the soldering, fit the EPROM (CUSTOM ROMs) on the adapter socket.

4. You will need to drill a 9 mm diameter hole in the case to accommodate the switch.  

5. Plug the cable you received into the adapter and the switch.

6. Power the device.

You will receive the ROMs arranged in a certain order, but you can move them around, erase and rewrite them, or replace them with different ROMs. The setup is customisable according to your needs.

The Quad ROMs Adapter KIT has four sound banks, which can be easily accessed with the switch:
ROM 1 - Roland TR-505 banks of sound
ROM 2 - Akai XR10 banks of sound
ROM 3 - Roland CR-78 banks of sound
ROM 4 - Oberheim DMX banks of sound

I can write the ROMs on other  DIP 27C040 EPROMs, for example on AM27C040, AT27C040, W27C040, and others.

Message me if you need software to write custom ROMs. You will still need the device itself - the programmer.

Soldering skills are required to remove your old EPROM and solder in the new Adapter KIT Quad ROMs.

The EPROM chip will be labeled to help you locate the correct chip socket.

The Roland TR-505 is not for sale, only the Quad ROMs Adapter KIT.

Be sure to take note of the marked orientation notch on the side of the EPROM to ensure correct installation.

EPROMS inserted backwards will be destroyed. Incorrect insertion of ICs is also likely to cause damage to the board.
