    Added an article regarding the different keyboard types used in the C64 over its lifetime, and some notes on repair.

  • About Spectrum Plus Membranes

    Posted on November 17th, 2016 Phil

    I’m often asked why I don’t stock Spectrum Plus / 128 membranes so I thought I ought to post something about them.

  • Hey hey ULA! 

    Posted on April 4th, 2016 Phil

    Announcing the Retroleum Nebula – A Spectrum (48) ULA replacement module. (Phew – after many months of tinkering, it feels good to finally get that off my chest!)

    The Nebula, as you might’ve guessed, is a small daughterboard that plugs into the Spectrum’s ULA socket and performs the same functions as the original ULA chip. It’ll be a bit cheaper than a second hand ULA, and should last longer ;)

    You can read all about it here.


  • Spectrum RAM replacement boards

    Posted on October 14th, 2015 Phil

    I’m certainly not the first person to make these but I’ve designed a couple of low power SRAM modules for the Spectrum to replace the DRAM chips originally used. They can be pressed into DIL sockets or soldered direct to the Spectrum PCB.  Available at the store should you need such a thing :)

  • SMART Card make-over

    Posted on July 2nd, 2015 Phil

    SMARTerOK nothing too dramatic but I’ve had the latest batch done with a blue solder mask, which I think looks quite (crank crank, pun coming..) SMART. Alas, due to unexpected customs shenanigans and component price increases I’ve had to increase the price by a couple of pounds – hopefully it’s still good value for money though (there is a lot of work involved manually putting them together by hand – gibber).

    Other SMART Card bits: Brendan Alford has modified his ZX-Diagnostics Spectrum Test ROM to work with the SMART Card. This is now included in the project archive . Also newly added to the “3rd Party ROMs” folder is Geoff Wearmouth’s Gosh Wonderful ROM. Many thanks Geoff to Brendan!

    Finally,  the SMART Card is featured on the latest instalment of The Spectrum Show – and I’m happy to report they like it :)
