It should work, shouldn't it? Well the action of the I/O lines has to be controlled by the QL driver - the pIC has no intelligence re this port - it just works to outside instructions. It should though be trivial if the clock is async. The hard part might be the driver - which will need to access TTs mouse registers. Beyond me certainly. It would certainly be nice to have a mouse with sH LITE, and I will fit the connector to all future production. -- QBBS (QL fido BBS 2:252/67) +44(0)1442-828255 tony@<surname>.co.uk http://www.firshman.co.uk Voice: +44(0)1442-828254 Fax: +44(0)1442-828255 TF Services, 29 Longfield Road, TRING, Herts, HP23 4DG
