Friday 13th Virus

Friday 13th Virus

The Friday 13th Virus – also known as “Jerusalem”, was created in 1988 in Israel to commemorate the 40th anniversary of the creation of the Jewish state.

The Virus activates on Friday 13th causing the destruction of affected files, and programs being used. It also slows down you computer by using up large amounts of memory.

The Friday 13th Virus was spread via email attachments, Floppy Disks and CD-ROM and has infected lots of business around the world.

How It Worked:

–  Infects files with extensions of COM, EXE or SYS and increases in size whenever the file is executed

–  It reduces the available memory on the computer

–  It caused computers to slow down and become almost unusable on Friday 13th

–  Every Friday the 13th the virus is activated, and destroys files on computers that are used that day

Amstrad PPC 512 / 640 1988

With the Amstrad PPC-512 and 640, Amstrad wanted to make the cheapest portable PC compatible computer, in the same way as the Amstrad PC1512 was for desktop computers. But, despite its pleasant form, this computer suffered due to its poor 9″ LCD screen. It had one or two 3.5″ 720 KB floppy drives and some versions could also be found with a 10 or 20 MB internal hard disk. If you were tired of the poor LCD screen, you could connect a monochrome or CGA monitor to the PPC at home. The Amstrad CPC series monitors could be used too. The differences between the PPC-512 and PPC-640 were a different colour case, a built-in modem (v21, v22, v22 bis and v23 protocols) and 640 KB RAM for the PPC-640. Both versions could run with 10 C size batteries (1 hour battery life), or with an external AC adaptor.

The Apple IIC Plus computer 1988

The Apple IIc Plus was the finest Apple 8-bit computer ever built, but due to a lack of marketing, the apparent backward step in technology compared to the 16-bit Apple IIGS, and the aggressive sales of the Laser 128EX/2, the IIc Plus also was to be the most short-lived of the Apple II models.

TK EXTended

TK Extended was a local version of PC-XT, launched by Microdigital in 1988. To minimize the technological gap between American and Brazilian models, the manufacturer offerred an upgrade card, named Cometa 286 (Comet 286), which goal was to replace the processor with a 7.15 MHz 20286 Intel processor, and also a 20287 math co-processor. This model marked the end of Microdigital, the same manufacuter of TK family, which included Sinclair ZX-81 (TK-85), Spectrum (TK-90 and 95) and also Apple licensed products adapted to meet Brazilian laws regarding national content.
