No need to go back that far. I can still make them. I miniatured Miracle's original good design (based on 555 timers) and put all the circuitry inside a Centronics plug housing. There are two designs - one for Z88 and one for QL. >But classical serial speed is really slow for the amount of colour >printing data >of today (especially with the top 2880x2880 or 5760x1440/720 dpi). >Laser printer with postscript are easier to feed (especially when they >have their own founts), alas they are so expensive and the colour is >rare for laser. .... and it relies on a fully working QL serial port at 9600. The port can seem to work OK, but often handshaking is dodgy. This will show up instantly when printing through the converter - it relies totally on the handshaking working. I even toyed with the idea of upping the spec to 19200, but have never got around to it. -- 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
