Greetings, All! 1. For sale is a 3-slot expansion-buffering board. Or rather, 2! there is no third, but there are holes for it are present, you just need to insert and solder. Price 30 rubles! 2. A set for the "hardware worker" namely: Not a working board "KAY-256" with a disk drive controller! What was hidden in her, only God knows, There is no ROM on the board (the firmware itself is available as file) But there is a WORKING processor! There is no VG-ha on the drive controller. There is an electrical circuit diagram. Price 30 rubles! All questions about purchasing this hardware direct into a soapy sink. Bye.
