Description

The VG-8235 is a computer made by NEC for the Dutch company Philips. For its release, Philips presented the VG-8235 as the first link of their audio-video-micro concept, being able to use the newly announced CD-i system, but few VG-8235 were ever actually seen connected to a CD-i. Although it does not have a NMS machine type label, it does have New Media Systems written on the top in full print.

It is the successor of the short-lived VG-8230, which only had 64kB RAM. The VG-8235 comes with 128kB RAM, not 256kB as indicated on the machine and the box by adding the RAM to the VRAM amount.

Nine variations of the VG-8235 were produced:

Product Region Keyboard MSX-BASIC
VG-8235/00 NL QWERTY 2.0
VG-8235/02 DE QWERTZ 2.0
VG-8235/16 ES QWERTY with ñ key 2.0
VG-8235/19 FR AZERTY 2.0
VG-8235/20 NL QWERTY 2.1
VG-8235/22 DE QWERTZ 2.1
VG-8235/29 DE QWERTZ 2.1
VG-8235/36 ES QWERTY with ñ key 2.1
VG-8235/39 FR AZERTY 2.1

This machine was also sold in Italy as the Phonola VG-8235.

The difference between MSX BASIC 2.0 and 2.1, is that 2.1 has a boot splash screen that prints 128kB RAM (regardless of how much RAM the system actually has), and that it supports a RAM disk (CALL MEMINI) up to 90kB, compared to the 32kB of older and newer MSX BASIC versions.

Like its predecessor, the VG-8235 has a single sided disk drive, in contrast with its successors and most other popular MSX2 models in Europe that featured double sided disk drives. An external disk drive can also be connected at the back of the machine.

The keyboard angle is adjustable. The second cartridge slot is optional as it is closed off by default but can easily be enabled by screwing the supplied cartridge holder onto the back of the computer.

Two system disks are included with this computer, the same as were included with the VG-8230, you can enjoy a drawing program in screen 8, called 'MSX Designer', which includes a demo mode: click 2 times on the last icon to launch it, press CTRL+STOP to quit it.

Besides this tool, the system disks provide MSX-DOS1 with a nice interface and MSX Home Office (Address Book + Word Processor).

The VG-8235 was followed by the NMS 8245, which features a new case, a fixed keyboard and a double sided disk drive.
