SCSI is the hardware connection; there are no twain drivers for 64 bit OS. You need the ASPI layer with SCSI for any Windows OS (32 or 64 bit) to recognize the scanner as a hardware device ( I do not know about USB connected scanners); but this is different from getting the scanner to work which is different from getting the OS to recognize the hardware and requires device drivers. The traditional scanner and scanner drivers were and are proprietary software connected twain drivers, which are only 32 bit and will not work with 64 bit OSs. Ed Hamrick by passes the twain driver and has written his own drivers for scanners; they may be 64 bit capable.

There i s something funny about scsi and aspi. For X64, I had to search the net and load some 3rd party ASPI stuff to run my usb scanner. Yes, I know this doesn't make sense, but I guess scsi is than a physical interface. That pc is in pieces at the moment, but I can probably find the stu ff I had to load once it is running again. -----Origin al Message----- From: "Tony Sleep" <tonysl...@halftone.c o.uk> Date: Sat, 13 Jun 2009 16:48:56 To: <li...@laz ygranch.com> Subject: [filmscanners] Re: Epson Perfectio n V750-M Pro Scanner, On 13/06/2009 James L.

Vuesc an should resolve antique s/w issues on Windows, though S CSI support may become more awkward I believe ASPI drive rs are available for Vista. On Mac I don't know with cur rent OSX, but similar was possible. Same applies to SCSI Nikons etc. Regarding physical service, I recently po pped the lid off my Polaroid 4000 (4 lever tabs) as it s eemed to have got rather flary and low contrast with som e strongly backlit slides that included bright background s, despite living under a dust cover when not in use. Half a dozen self-tappers later and I was able to remov e the lamp holder and the top of the film carrier carria ge. I was then able to clean the angled mirror with a DS LR sensor swab - it was covered in a thick layer of dust . Inspection with a torch showed the lens to be clean, re flected in the mirror. I then cleaned every trace of dus t and dirt from the mechanism surfaces I could get at, a nd wiped and re-lubricated the helical carriage advance screws. Result : a total transformation! Scans bright and clean, loads more shadow detail - virtually everythi ng in Kodachrome. No flare and colour much easier to get spot on. The mechanism sounds happier for lubrication to o. No more misfeeding neg carrier either, which the scan ner has been mistaking for the slide carrier half the ti me, for about the last 4 years. I wish I'd done it earli er, as I now think I should really rescan quite a lot. > Has anyone had any experience with Epson's > V750M? The specs. look impressive if they hold up. No exper ience, but if I had the money I'd have bought one to scan the relatively small amount of 120 I have. From reading reviews the V750 is very little different from the much cheaper V700. Lens coating seems very slightly better a nd you get Silverfast with the 750. Most important factor appears to be stand-offs for the film carrier, which ca n be improvised. Personally I'd use Vuescan anyway. -- Regards Tony Sleep http://tonysleep.co.uk --- --------------------------------------------------------- ---------------------------- Unsubscribe by mail to list ser...@halftone.co.uk, with 'unsubscribe filmscanners' o r 'unsubscribe filmscanners_digest' (as appropriate) in t he message title or body ---------------------------------------------------------------------------- ------------ Unsubscribe by mail to listser...@halftone.co.uk, with 'unsubscribe filmscanners' or 'unsubscribe filmscanners_digest' (as appropriate) in the message title or body ---------------------------------------------------------------------------------------- Unsubscribe by mail to listser...@halftone.co.uk, with 'unsubscribe filmscanners' or 'unsubscribe filmscanners_digest' (as appropriate) in the message title or body
