Wide-ranging editorial covering Sinclair community news for early 1990: rumors of Apple Mac and NeXT emulators for the QL, a new MS-DOS Cambridge laptop with 3.5-inch drives, the tenth anniversary of the Sinclair ZX-80, the launch of the Ottawa-Hull TSUG BBS (613-745-5534), and Harmer’s forthcoming books on ZX-81 assembly language, Tips/Tricks/Techniques, and the LDOS disk system. Also notes continued ZX-81/TS1000 interest from student users and the potential for controller/EPROM programmer applications.
