These are designed as a drop-in replacement for the original aging and power hungry ROMs. Unlike other designs and 28 to 24 pin EPROM adaptors, these hide all the ugly stuff out of sight to provide the cleanest possible look.

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+ - Switchable between regular VIC-20 font and C64 font via a small switch on the bottom of the PCB.

All ROMs are hand assembled and tested before shipping.
