1 ;"The SPRINT recorder is a device consisting of a normal tape deckwhich runs at 4 times standard speed and a replacement SpectrumROM. The ROM has a modified cassette interface routine whichSAVES and LOADS at four times normal speed."
1 ;"TAPE 12 DECEMBER 84 SIDE 1"

1 ;"On the hardware front Sinclair launched the SPECTRUM PLUS and we got a review model of the SPRINT recorder from Challenge Research."''"The PLUS is a 48K Spectrum in a QL type keyboard. The new manualand the unshifted punctuation should make it easier to use. They justify the `179.95 price by including TASWORDII, SCRABBLEand 4 other tapes. Very pretty."
1 ;"MUSIC TYPEWRITER starts you off with a sample in the Baroque style which is a joy to listen too as well as to watch."''"I only have two reservations about this excellent program. It will not accept a 2/2 time signature and the print out to the ZX printer is only 1 bar across."
1 ;"MUSIC TYPEWRITER displays the notes as they are played."''"MUSICMASTER can only offer a static menu as it BEEPS feebly."''"The Sinclair program is creditedto 'Incognito Software Ltd.', I can quite understand the desire for anonymity."
1 ;"Lots of stuff to get through this month. First some answers to Mr Lant's questions about ournew serialised adventure. This will start next month and will be 48K only."
