First, here is a long overdue review of Fred Nachbaur’s SyncWare News. (See his previous contributions to QZX.) Since he isn’t a ham, we gave him a call of **** and he was grateful. Anyhow, in April ’83 he began Syncware News, and sent out a lot of complimentary copies. His publication is slanted toward professional & educational software for electronic applications, for the Timex/Sinclair computers of course.
Let me give you the titles of articles in the three issues I have received to date and you can decide if SyncWare News is for you. Polar/rectangular conversions, straight line/vector plotting, integration/RMS calculations, multiple data plotting, byte-pyncher programs, simultaneous linear equation solutions, & electronic circuit analysis. Also offered are hardware tips and product updates. If you are into math or want to learn more about it, you will enjoy Fred’s publication. The articles are well written, like a mini-text, and the programs not only save the kids a lot of time doing their homework, but are useful for dusting the cobwebs out of dad’s/mom’s head. I have thoroughly enjoyed them all and hope to find time to experiment with them soon.
If interested, send $15 for 6 issues to SyncWare Co., PO Box 5177, E1 Monte, Calif. 91734.
Also received from Fred was a copy of his Common Emitter Transistor Amplifier Design Manual/Program. This 40 page booklet is really neat! It’s a complete tutorial on the design & application of Class A common emitter transistor design. Here’s a list of the MENU topics: 1. Input/View transistor specs, 2. Design amplifier from specs, 3. Analyze Q-point stability, 4. Low freq/mid-band response, 5. High freq response, 6. Standard component values, 7. Schematic diagram, 8. Re-run analysis. This booklet will take the beginner completely thru transistor designs steps, plotting nice voltage, current, & beta plots, providing useful tables of operating parameters and the neat schematic (see below). The math is not ‘heavy’ in this booklet, in fact the computer does it all for you. I highly recommend this if you are interested in circuit design. It sells for $20. Or just drop him a note, telling him QZX sent you, and ask for more details on this booklet or his News.
