You can protect yourself and your data by using both the Connectivity Pack and a RAM card back-up regime. You can back up files using the Connectivity Pack regularly, perhaps once a week. Then you can group your weekly backups by month and store the files on floppies. This establishes a record of what you did and when you did it.
Because you can keep a RAM card in your 95LX, you can back up important files several times a day, or more often if what you're working on is critical. A prudent guide is to back up your 95LX as often as you would your desk top PC if you where carrying it around with you.
Sound simple? It is. And it's insurance well worth buying.
