Grillet & Co - Technical Consultants
Always ready to support you in meeting specialist requirements where security and reliability are the highest priority.
We can deploy high performance, secure, servers for you
The secure alternative to the cloud (someone else's computer) is having your own computer - knowing were it is - and knowing it, and the data in it, will stay where you put it. With the right systems in place, you, your staff and your clients, can still access it, securely, from anywhere in the world.
Current projects include Databases, Internet radio, PHP web frameworks (like Slippr - used for this site) and others.
"Full Stack" knowledge learned over almost 60 years
We have designed systems from transistor level to complete computer networks.
Digital Electronics
Andrew Grillet saw EDSAC 1 when it was still working. He was employed to debug valve based TV monitors at PYE TVT, and debugged valve based digital counter-timers.
Andrew designed one of the most widely used controllers for 1/2" tape drives in the 1970's, and developed a 1/2" tape controller for the BBC micro. At GEC, he wrote Unix tape and disk drivers for the GEC models 21, 42 and 63.
Andrew invented the Sinclair Microdrive
I developed ST506 (hard disk) controllers for the Apple ][ and BBC Micro.
At GEC, Andrew was the chief hardware architect for the CARDS database engine (a UK government research project to reconcile DNA structures with the proteins they generate).
Software:
Andrew designed and developed the GODS operating system (similar to CPM and DOS, in the same era).
At STC, Andrew wrote the software for the first text messaging pager.
At Storno Ltd Andrew wrote the software for the Storno 4000 Automatic for
British Rail. (The first "mobile phone": it was hand-held,
and could dial any phone on the public phone network)
Andrew also wrote the software for other Storno 4000 variants,
including the ones used by London Transport and British Airways.
Storno was bought by Motorola while he was working there.
The team has designed and implemented telecomms billing (phone calling card system),
money transfer (Send Money Home), inventory management, factory progress control,
requirements management package.
