So I picked up this large boy from the MSU Surplus Store<\/a>:<\/p>\n\n\n\n

Sony Digital Mavica MVC-FD91 (c. 1998 CE) \u00e2\u20ac\u201d yes, that’s a 3\u00c2\u00bd” floppy drive on there<\/figcaption><\/figure>\n\n\n\n

You get about 7 high-resolution pictures on a disk. And high resolution by 1998 standards means this:<\/p>\n\n\n\n

1024\u00c3\u2014768 whole pixels: that’s huge<\/em>! The camera is autofocus with image stabilization, so it was quite a nifty unit at the time.<\/p>\n\n\n\n

If you care to dig about in such an ancient file, I’ve got a matching image and its 411 file here: MVC-005X.zip<\/a>. And manuals? Here: Sony_Mavica-FDC91-W0007229M.pdf<\/a><\/p>\n\n\n\n

Most annoyingly, the camera really only likes real<\/em> Sony batteries, or it shuts down with an “InfoLithium<\/a>” battery error (swearies in link). As this battery format is now used in generate photo lighting systems and Sony don’t make it any more, this may be a camera that dies from DRM before anything else.<\/p>\n","protected":false},"excerpt":{"rendered":"
