Thanks. Omnibook obtained for few quid on Ebay. Good condition, starts and runs BIOS ok. Being older novice am keen to take on challege to get it operational for wife!
New approach. Found Toshiba CD Rom drive with PCMIA cable and card which seems to be plug compatible with the Omnibook; unfortunately, the Drive doesn't run. Tomorrow, maybe Ebay or local Maplins can produce a low cost PCMCIA Drive. Sounds good??
