| A New Face for Quantum_Levels |
The Timex/Sinclair computing world has reached another crossroad. This issue incorporates Quantum_levels and its sister publication SyncWare News into one magazine. This has been done for financial reasons. Don’t worry though, all monies for subscriptions are kept in escrow for each issue and in fact the magazines do pay for themselves. We have seen the |

| Custom Tape/Disk Directory |
This article describes a way for owners of the LARKEN disk system to get around from program to program more easily in a multi-drive system. Larry Kenny has made a disk drive system possible for many T/S 2068 owners by making an interface for about $120 while drives can now be found used for under |

| Eyeing the QL |
This part of the article is written to be non-technical and in fact somewhat historical in nature. I would like to thank Lee Terry, of Comsat Labs, for his help in identifying the true problem discussed herein. He was on a team that wrote the book that was published as the Motorola MECL Handbook. (ECL, |

You remember Alex Sweitzer (Geometry Plotter, SWN Vol. 5, No. 3), who teaches an elementary-school class that works extensively on TS computers. This program was written by one of his fifth-grade students. |

| Playing With Electricity |
When I was in Seattle at the Sinclair Fest, I discovered people had questions about the memory layout of the QL. In particular, the command RESPR was not understood. The QL memory map has two aspects, what the hardware allows 8 what 0205 expects. The hardware aspect is straightforward; the 68008 has 20 address lines |

| Programming by Procedure |
In ARCHIVE the only obvious decision making command is: IF … ELSE … ENDIF. It works as you would expect it to work in SuperBASIC, but ENDIF is always required. It must also do the work of SELect. There is no THEN. Instead use a colon. |

| The Solution: An IBM Emulator for the QL |
The variety of software for the QL, while not nearly as extensive as for IBM family machines, fits the needs of most QL owners, at a much lower price than their IBM counterparts. Occasionally, however, QL owners (as with other computer users) have need to run software that is not available for their machine. Examples |

| Think About This! |
Did you ever wonder just how fast the speed of light (and electricity) is? Well, at 186,000 miles/ second thats lots of inches/second. In fact it is 11.78 inches /nanosecond. Now add harmonics (think of 12 individual notes in an octave on the piano keyboard). If you go 1/12 up the octave you come to |

| TRA_BAS 1.1: RS-232 Translation |
RS-232 TRAnslations may seem a bit esoteric to some users, but the implementation of an RS-232 TRAnslation can resolve minor printer interface problems. Generally, your QL (and most other personal computers) telecommunicates with other computers along with communicating with other devices using the non-standard (!) ASCII code. Fortunately, the significant alphanumeric series is standardized. Nonetheless, |

Every schoolboy knows that you shouldn’t leave your monitor or TV screen standing idle for a long time with a static pattern on it. (That’s why the TV people caution you not to leave your MUTE command in effect for a long time–turn the volume down instead.) Anyone who ignores this warning is in danger |
