Philips VG-8235
Interfaces on the back

The Philips VG-8235 was an MSX-2 - home computer from Philips and came in 1986 to the market. The new price at that time was around 1500 DM . The VG-8235 was one of the best equipped MSX home computers at the time. It had already integrated a 3.5 inch floppy disk drive (capacity 360 KByte) and was equipped with 128 KByte video memory. The video memory enabled different screen modes with a maximum resolution of 512 × 212 with 256 colors.

The computer was the first MSX from Philips to be advertised because of its graphics performance and the ability to connect a Philips CD-i device. The VG-8235 was an attempt by Philips to regain ground in the computer market for the MSX system against the very strong competition from Commodore and Atari . It was relatively widespread in its country of origin, the Netherlands , where the MSX system had already been successful in the past. In other countries with a high C-64 distribution, sales efforts were not rewarded despite intensive marketing measures.

The computer had a German keyboard that could be set up diagonally using switches. It had two cartridge slots. One was located above in the middle and had a lid that closed automatically when there was no cartridge in it. The slot on the back was screwed by default and first had to be screwed free by the owner and supplemented with a shaft. The reset button was next to the status LEDs on the surface. On the back it had interfaces for a cassette recorder , a printer, as well as three interfaces for monitor and television ( SCART , PAL and DIN FBAS interface) and an interface for another drive. On the right side was the floppy and two joystick ports.

Inside it was equipped with a Z80A processor with a clock frequency of 3.58 MHz, a working memory of 128 kByte and a video memory of 128 kByte, as well as a 64 kbyte ROM. The ROM not only housed the MSX-BASIC , but also an instruction set for controlling the floppy disk drive. In contrast to many other MSX devices, Philips did not install the Yamaha YM-2149 sound chip, but instead used the Yamaha S3527 .

variants

  • VG-8230: The difference to the VG-8235 was the 50% smaller main memory (64 kByte). This means that no memory mapper was required, as 64 kbytes were exactly in the addressing range of the 8-bit processor.
  • VG-8240: Was a VG-8230 computer with a "superimpose" button next to the status LEDs. The third LED was labeled "super impose" and the housing also read "Graphic superimpose". Only 15 prototypes of this computer were made.
  • NMS-8245: Was a VG-8235 computer in a slightly modified housing and already equipped with a 720 kByte floppy disk drive.

Trivia

  • Boris Becker was given a Philips VG-8235 for marketing purposes.
