| From the Chairman's Disk | Looking back and thinking about the years of enjoyment with the T/S 2068 I fondly remember the first T/S Fest which was in Indianapolis in May of 1987. That was my first time to see all the goodies that were available for the T/S enthusiast. | |

| Z80 LCD | Many of us have dreamed of controlling the world with a ZX-81 (what else is it good for?). For standalone or portable applications, a TV or monitor display is quite bulky and power hungry. You need a portable low power display and that would be a job for the Z80/LCD display. | Timex/Sinclair 1000 |
| ZX-81 Video Display System | In order to speed up application program execution time, the FAST mode uses 100% of the CPU time for executing the application program but there are times when the application program is idle When the program is STOPped or PAUSEd or waiting for keyboard INPUT, the keyboard is checked and if no key is down the video is generated independent of NMI pulses. | Sinclair ZX81, Type-in program |
