RWAP Software - support for Sinclair QL, ZX Spectrum, Cambridge Z88 and more

Mekall takes RWAP Back To The Future

RWAP services the needs of a surprisingly large group of existing users for retro computers by supplying spares for 1980s machines such as the Sinclair QL and ZX Spectrum.

The issue RWAP had was finding replacement keyboards for these well-used and well-loved computers.   After extensive searching in the UK and overseas RWAP managing director Rich Mellor found Mekall – a Glasgow-based engineering firm who specialize in the manufacture of membrane circuits who could manufacture keyboards to his specifications.

Rich said: “Mekall were willing to work with us to produce small production runs.  We did not require thousands of units and Mekall were willing to be flexible.  I found it very easy to communicate with them as they did not give me the ‘hard sell’.  Also I found the quality of their samples to be exceptional.  They have worked closely with us to develop a range of different membrane thicknesses and technologies to match, or improve upon, the different technologies used over 30 years ago.”

He continued: “Since starting work with Mekall in 2010 we have found the company to be very reliable and quick to respond to feedback on how their products could be improved to help address issues.  Quality has been excellent, after some initial fine tuning, they quickly met my requirements.  Our relationship has also worked well with regards to creating a just in time ordering system, where, in liaison with ourselves, partial orders have been delivered, with remaining stock delivery timed to arrive as required.  They have always kept to budget and quotations provided and have always delivered on what they promised.”

“In summary, I would say we have found the production and sales team at Mekall very helpful and easy to work with.  They obviously take pride in their products and we are glad to work with them in continuing support for 1980’s computers such as the Sinclair ZX81, Sinclair ZX Spectrum and Sam Coupe.   It is also good to know that due to their pricing structure and our relationship we can provide replacement keyboard parts at an affordable price for enthusiasts of rarer retro computers such as the Enterprise 64 and I look forward to working with them on future projects.”
