The working unit has 256+384 KByte RAM, a IBM WD25 (20 MByte) harddisk and two floppy disk drives (360 KBytes). The hard disk drive controller is a XEBEC (62X0786).

The memory expansion card is from Quadram, namely the short version. As far as I know, there is no documentation on this short card on the Internet.
