Hi Whippet
Speaking from memory and from postings on this forum, I believe Keymaster stopped producing programmers around 1998. Millenium produced some software for the Keymasters but (and this needs confirming) I don't think you can program funcards with the keymaster.
If you want to get into programming funcards as well as gold and silver, you might consider purchasing the Elvis programmer. Costs £45 including serial lead, software and a gold card.
That's what I did but, as others will tell you, there are alternatives but I do believe they will be more expensive.
