Just make sure not to short the exposed joints on the top of the ROMs to anything metal (like an RF shield). Power consumption is around 4mA (20mW) vs the 85mA (425mW) of the original mask ROMs. As such these run completely cool and consume a fraction of the power, ensuring they will almost certainly outlast all the originals and help lower the overall tempreature of your machine. **Be sure to select the correct Kernal for your machine. NTSC uses a 6560-101 VIC and 14.31818MHz crystal, PAL uses a 6561-101 VIC and 8.867238MHz crystal** **The character ROM comes in two flavours:** - 901460-03 - Standard drop-in replacement - 901460-03/901225-01 - Switchable between VIC-20 and C64 fonts 901460-03/901225-01 (formerly named 901460-03+) includes a small switch on the bottom edge that sticks out by 1mm from the underside of the PCB. It is safe to switch fonts while the machine is running. All ROMs are hand assembled and tested before shipping. ## Shipping policy ****EU customers please note taxes and duties will NOT be collected during checkout and you will need to pay VAT, duties, plus any other customs charges to your local customs/postal service. Refusal to pay these fees will result in your order being returned to sender and NO REFUNDS WILL BE GIVEN ON THE ORIGINAL SHIPPING COST. Apologies for the inconvenience.**** US, UK and Canadian customers please note taxes and/or duties will be collected during checkout, you should not need to pay any extra upon arrival. Any locations 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 items purchased from my store will be declared at their equivalent price in AUD based on the current exchange rate at time of shipping. 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 or gift as Australia Post does not allow this for commercial goods. All orders are shipped with tracking usually within 2 business days. All information above is subject to change without notice.
