Published in the International ZX81 Magazine: ZX81 versus 486PC
The Battle of the Giants
The ZX81 compared with a 80486-33Mhz PC
Dear Friends of the ZX81,
Time and time again we find out that many wellknown magazines that advertise in their magazines, and give less credit to in reality stronger computers simply by doing tests without real depth. The ZX81 has suffered many times because of this and has clearly been less appreciated because of this.
The ZX-Team has now done an objective and completely 'neutral' test between these two computers.
The ZX81 in this test is a standard ZX81 with 1K, the 486 PC uses a 130Mb harddisk.
First we looked at the design, the ZX81 sure is in fashion with his nice
black colour, also the nice flat case of the ZX81 is much more stylish then
a tower PC in this commonly used outfit, a clear case.
The PC reached a 8.5 CU-Value, which is about the same as a coolbox with
it's lid open, the ZX81 came with it's keyboard in the direction of the
wind, with a great CU-Value of 0.36.
Benchmark 1 is the calculation of a sinus of 30 degrees, it took the ZX81 9.43 seconds, while they where still looking for the appropriate software for the PC to do this......
Benchmark 2 exists of a complete routine written in machine language in one line and entered as a direct command from the keyboard.
1 REM <SPACE> TAN RAND USR 16514
The difference in mobility ended up in the advantage of the ZX81. The PC was to heavy to pick up.....
The ZX81 also has the advantage of easy recycling, the ZX81 does not leave many parts.
The economic test was about consuming electricity, well I guess you know that one already.
Review of the testresults:++ = very good, += Good, o = Poor, - = Very Poor, -- = Terrible
Conclusion: We ZX81 users can look optimistic into the future, I certainly would never sell my ZX81.

I have only changed the "outfit" of the text.
The German ZX81 Team is a still active group of ZX81 enthusiasts. They produced some fine hardware extensions: A ZX81 with a LC display? Everything seems to be possible.
