APDL Turbo processor upgrade

  • Do you have a Strong ARM RiscPC?
  • Would you like a 20 to 25 percent speed increase?
  • Would you be prepared to pay around £40?
If the answer to these is 'yes' then we may be able to help.
Turbo processor

This is an exchange processor upgrade for any Strong ARM RiscPC. Although normally done as an exchange we also sell fully guaranteed 276 or 287 Mhz Turbo processors for people who don't already have a Strong ARM and new Revision T Turbo processors with or without part-exchange.

The APDL Turbo processor upgrade has a boosted clock rate and other modifications to increase speed and reliability. This method of improving performance has been widely used by enthusiasts, and the Turbo 287 can give a speed increase of between 15 and 30 percent depending on the type of program being run.

Most users are naturally apprehensive about carrying out this type of work. There is the possibility that the processor could be damaged as not all will work reliably at high speed, leaving you with a dead computer and a large bill for a new Strong ARM. The APDL Turbo upgrade removes the risk of running a fast processor. Your Turbo processor upgrade is fully guaranteed for one year so we carry the risk. Despite being clocked much faster than the standard Strong ARM it actually runs cooler, so it should have an even longer life.

If you are exchanging your existing Strong ARM we will send your new Turbo Processor and then, once you have fitted it and made sure that everything is working properly, you have 30 days to return your old Strong ARM to us. This means you aren't without your computer while your processor is upgraded. As security you will be billed £45 more than the quoted price and this sum be refunded upon receipt of your original processor in good condition. Alternatively you can send us your old processor first with payment in which case no security deposit is required.

In each case carriage is £5 UK, £9 outside UK.

Don't forget when you purchase an exchange processor you will be charged £45 more than the quoted price and this will be refunded to you when you return your old processor in good condition.

Some comments from users.

"The 287-T installed in a RISC OS 4.02 machine has a truly incredible performance."
   David Coppen

"... things I did measure showed improvements from about 4pc to 55pc."
"My greatest satisfaction came from Fireworkz. RiScript also seems to buzz. e.g. loading the Oregano manual and rendering their front page pic improved by 38.5pc."

   Barrie McElroy

"If I were living state-side, I'd be tempted to describe the APDL upgrade as a 'no-brainer' - that is to say that the decision is very simple."
"... for a very small outlay you get a noticeable speed increase. After several years of owning a 200 or 233Mhz processor, this is a simple and effective method of rejuvenating your system without resorting to feeding it viagra!"
