Lowercase ROM was made with an pin-rearranged 2706 EPROM. Additional RAM was inserted, DIP switches were set: works perfectly. However, with lowercase ROM installed and DIP switches set, but extra RAM missing, the Space "0x20" was displayed as a " ` ". So I think you have an RAM issue. Perhaps cleaning the socketed extra RAM helps? Joerg ---- Thanks - that sounds like my symptoms exactly. I'll check out the RAM. Steve ---- Well, there you go. The sockets for two 2102 RAM chips are empty! Anybody have a couple of these guys they can spare, or a quick pointer on where to buy them?

Thanks all, esp. Joerg for the tip! Steve
