Refurbished Board For Sinclair ZX Spectrum 48k Rubber Keys

Description

A fully refurbished Sinclair ZX Spectrum board, suitable for you to install in the case of a Sinclair ZX Spectrum 48k (with rubber keys).

It will also work in a Spectrum + case, but you may want need a reset button to be fitted. Please note that I also sell refurbished boards for the Spectrum + that include the reset button already fitted – see the Product here.

This computer board has been refurbished by PopeyMon Games and Fun. I have sold many Spectrums to happy customers.

This board has been fully tested and working. Tests have been run to ensure reliability. Tests are run with the power off and tests are run with the power on. Tests include:

• the notoriously unreliable DC-DC converter circuit
• display circuitry and output
• with a keyboard (not included but used to test to make sure the keyboard circuitry works)
• all lower RAM chips
• all upper RAM chips
• the ROM chip
• the CPU chip
• the ULA chip
• the edge connector has been tested with a joystick interface and with a Retroleum Smartcard to ensure that it can run with modern components

The TV output has been modernised to use “composite video” which is available on most modern TVs. It replaces the original RF output which is inferior. You will need a composite video lead and please check that your TV has a composite video output connector.

All electrolytic capacitors have been replaced with quality new ones. These capacitors go bad over time, with heat, storage conditions and other factors. They can then damage the computer or affect its function. Replacing them reduces the likelihood of problems in the future. The replacement capacitors are quality capacitors – Vishay, Panasonic or Nichicon.

This is for the computer board only. You will need to supply a case and keyboard. I have these for sale.

If you want the board to be fitted to your Spectrum, then please get in touch.
