      We can easily spot the 7 expansion slots inside the case. Next to them are the keyboard and video connectors. One the right part are the power cord and the ON/OFF switch.

      I have one or two AVT's in my attic. I used it to build a system named "MicroCompo" in the eartly 80ties. It was intended to be used as complementary keyboard for Photosetting systems. For this I modified the hardware and the character generator for displaying 128 charactrs. I replaced the original keyboard by a Cherry-keyboard and wrote an editor program.\

This is quite a rare computer ! It was conceived by a dutch company called AVT Electronics. AVT is short for Alex van Tienhoven, then the owner of the company. This computer was made in Korea as per AVT's design...

This obscure system is Apple II compatible (hardware & software), hence the "Comp2" name.

The system is composed of a separate keyboard and a big case housing two 5''1/4 disk-drives, the mainboard and 8 expansion slots. Seven of these slots are Apple compatible and the last one is reserved for an optional RGB graphic color card...

The Comp 2 has 64k RAM that can be expanded up to 1Mb through 256k cards.

A Z80 (4 or 6 Mhz) board was also available and enabled the use of CP/M.

**David Winter** reports :\
I have an AVT2 computer without the disk-controler card. But I used instead an Apple II disk-controler card and it works well ! I then tried several Apple II games, and they played well too. This system seems indeed hard & soft compatible with the Apple II.
