Luma bypass boards for use only with the Commodore 16/+4/64/128 RFOFF.

This is only for people who have already installed an RFOFF and want to add the luma bypass board. Be sure to select the correct option for your machine otherwise you risk damaging the VIC-II or TED.

Install

Remove the VIC-II/TED, install the luma bypass board and insert the VIC-II/TED into the bypass board - be sure the notches on the sockets and chip are aligned. Connect the mini coax cable from the bypass board to the RFOFF, and remove the luma bypass solder blob on the RFOFF so the luma bypass jumper is OPEN.

Note as the bypass board adds some height, it may not be possible to reinstall the original heatsink. It is highly recommended to add a new heatsink to the VIC-II/TED (and VDP on the 128) if you haven't already.

Please note the bypass board is intended to be installed in the original VIC-II/TED socket. If you are building a replica machine you must install a dual wipe socket - do not solder the bypass board directly to the mainboard.

Shipping policy

In order to comply with customs requirements all items regardless of size are sent as a parcel (small box), however there is no extra shipping charge for multiple items. I am not able to send anything as a letter as Australia Post does not allow this for commercial goods. All orders are usually shipped with tracking within 2 business days.

US customers please note import tariffs and associated fees will be collected during checkout. You should not need to pay any extra upon arrival.

EU customers please note VAT will be collected and paid for all orders. You should not need to pay any extra upon arrival, however extra charges do apply when the items total over €150. To avoid this from happening, orders to the EU are limited to €140 (excluding taxes and shipping).

UK customers please note VAT will not be collected as orders with items totalling under £135 (approx. €150) should not attract any VAT or import duties. To avoid potential duties or customs fees, orders to the UK are limited to €140 (excluding shipping).

Any countries not included above may also be subject to tariffs/fees/duties on imports from Australia, and you may be required to pay fees upon arrival.

All information above is subject to change without notice.
