Sellam said: As Andrew Davie said, seems so. I have the VZ200 and VZ300 as sold by Dick Smith, and the VZ 200 manual says copyright Video Technology 1983 on the first page. To all "Oz-nerds" (as opposed to Yank-nerds or Limey-nerds?:) - in the book "Programming the Dick Smith Electronics VZ300 Personal Computer" by Tim Hartnell, there is a section on attaching a disk drive (Cat X-7302) via a floppy disk controller (X-7304) which can take two drives. You also need the 16K memory expansion (X-7306). I have the latter, but I have never laid eyes on a VZ disk drive. I assume they are rare - if you had the sort of money I expect they wanted for them in 1986-7 (the system units were still being advertised in Aust Personal Computer in June 1987 for $A169 including datacasette and 4 programs) you would have bought a better computer! The boot screen with the disk drive attached is supposed to say VIDEO TECHNOLOGY DOS BASIC V1.2 READY So has anyone ever seen that? Phil in Brisbane, Australia.
