A Review of the Sinclair Spectrum Plus Review of Spectrum+ and modifications to make it work better with NTSC TVs and monitors. Sinclair ZX Spectrum
A Review of the Sinclair Spectrum Plus The latest home computer from Sinclair is the ZX Spectrum. What sets this computer ahead of the other Spectrums is the larger keyboard with extra dedicated keys. The Spectrum looks a lot like the QL small business computer but with a few less keys and no microdrives attached to the side. Timex/Sinclair 2068

Additional Notes on the Hardware of the T-2068 & Disk Drive Disassembling the T-2068 reveals a circuit board smaller than found in the American computer. It is a very professionally designed board with no wire jumpers. A stand alone RF modulator replaces the video/RF modulator circuitry of the TS-2068. There are no trim pots or adjustable components except for a fine tune in the RF modulator. Timex Computer 2068, Timex/Sinclair 2068
Additional Notes on the Spectrum Plus The Spectrum Plus comes with an excellent manual printed in full color.

SUM grew out of a Timex Sinclair user group formed in Gainesville, in September 1982. The user group’s newsletter started out as postcards sent to a handful of people telling them when and where the next meeting would be.

In January of 1983, the group started sending out a single sheet of typed “news”. Slowly it grew to two pages, and then to a four page newsletter — all typed. The July 1983 newsletter was the first one created using a word processor: Memotech’s Memotext and the Seikosha GP-100 printer (also known as the Gorilla Banana).

Over the next year, the newsletter stayed at four pages, covering events at the last meeting, reviews, short programs submitted by user group members and where to find hardware and software.

When Timex exited the market, the newsletter’s editors, Richard Cravy and Joe Williamson, thought that interest would dry up.

“Instead, we were flooded with requests for more information on our group and newsletter. There was a great thirst for Sinclair knowledge from everywhere. Everyone wanted to unite to keep the faith going. So did we.”

At that point, Richard and Joe decided to turn the newsletter into a magazine.

August 1984 was the first issue of SUM Magazine. It was eight pages long, had six articles and two ads.

SUM merged with Time Designs Magazine after the July 1986 issue (volume 4, number 7).

The first year of SUM was reprinted in The Best of SUM.
