Re: Replacing a 4116 VRAM with a more reliable 4164 - Courte
The use of 4164s is a cheap and relatively easy way to replace the faulty 4116s but the Spectrum hobbyists have a more elegant solution too: http://zx.zigg.net/LRR/ Of course this can't be directly plugged into an MTX due to different arrangement of chips but I bet the same schematic could be used t...

As I said, this is my first MTX but I've seen one in an computer magazine ad back in the 80s and I've been itching to own one pretty much ever since. Back then I had a Vic-20 and a C64...
