As mentioned in a couple of other posts here, the Z88 is a great machine. It comes with 32k of RAM, although this can be expanded with plug in cartridges. An alternative, however, is to replace the internal 32k with something larger. This photo tutorial shows how you can expand the onboard memory to 512k. This involves some pretty hardcore soldering, and is not recommended for your first soldering project. More importantly, there is some delicate unsoldering too, and if things go wrong, you've wrecked your Z88. You have been warned!
