Hello Everyone, I'm currently restoring a Dutch Holborn 6100 computer. It is an 1982 CP/M machine. Originally it had a hard drive. But the RMS-518 drive, the Xebec S1410 and the Astec AC9251 power supply are gone. Can anyone help me getting the original Xebec controller and power supply? I'd put some pictures on this Dutch forum. http://philipsradios.nl/forum/index.php?id=14288 And can anyone tell me the specifications of the RMS-518 disk? I've found the 503, 506, 512 and 514 but not the RMS 518... Thanks in advance! Regards, Roland
