Acer 1714  -  3.4GHz P4 Laptop with 17" LCD   desktop performance in a mobile form factor

Acer Aspire 1714SMi Laptop with WindowsXP. As new condition. Bought for demonstrating Avid Xpress & Premiere Pro at trade shows but otherwise virtually unused.
It's got a big 17" LCD screen running at 1280x1024 from an Nvidia 5700 chipset with 128MB RAM and a full spec 3.4GHz Pentium 4. It also has S-Video TV out from which you can get a full-screen version of Premiere or Avid's video preview window.
The system RAM is 1GB (2x512MB), but could be swapped for 2x1GB. Likewise, the 120GB hard disk is a full size 3.5" unit (not the normal 2.5"), so it too could be swapped for anything up to a 500GB unit. On top of that, it's got a DVD writer, two 1394 firewire ports, both gigabit and wireless ethernet and lots of USB2 ports. Complete with original box & accessories. The replacement models aren't as upgradeable because they've gone back to using 2.5" disks to keep the size down.

Summer Holiday closure - Please note:

We will be taking a long overdue holiday towards the end of this month, closing for business at 12 noon on 22nd July and reopening on 2nd August.
Emails will be answered at some point each day during this period, and orders taken (for which we will order extra stock if required), but nothing will be despatched until 2nd Aug. Apologies for any inconvenience caused.

What we're about . . .      ZEN is not a traditional Audio-Visual dealer who started selling computers, nor is it a computer shop that also sells video products. You won't get any salesmen giving you the "hard-sell" when you call, just straightforward advice and information - which for some callers is the knowledge that they don't need to buy whatever it is they thought they needed! Above all you'll be dealing with someone with a wide range of experience and knowledge of both PCs and video production. We're not the biggest, nor necessarily the cheapest, but we are one of the longest established computer/video specialists in the UK.

Company history . . .      ZEN was started in the 1980s by Martin Kay, then working for ITV at Granada's Manchester studios, who built his first 6502-based computer in 1979 from an Ohio Scientific kit, bought in the USA whilst working as a Sound Recordist on a film shoot for World In Action. With the advent of the Amiga, which could be gen-locked to a video source, Martin started writing a variety of video-related software. This included subtitling & tele-prompting, ident clocks, scoring software for sports & gameshows, and specialist software to mimic other computer displays for use in TV film dramas like Cracker, Prime Suspect and A Touch of Frost. Martin left Granada in 1993 to concentrate on his computer-video activities with ZEN, following a natural path into non-linear editing systems, for many years the main business activity, although he still maintains an active interest in video production.
