The utility can then be used to create loader programs to configure different types of UDG hardware (CHR$128 and Quicksilva formats if 64 or 128 characters, and dk'tronics/Kayde format if 64 characters). The loader programs can be read into a ZX81 from cassette, a ZXpand or ROM cartridge. In the future, the utility could be extended to support other formats once full details about them become known, e.g. Haven Hardware Character Board.
