ICL OPD/Merlin Tonto

My QL has got OPD microdrives hacked onto it (by me). The OPD microdrives have much the same mechanism, the same ULA, the same joke-of-a-tape-head-mounting [1], etc. There are electrical differences -- I remmeber having to swap wires around between the QL connector and the OPD drives and I think I had to add a 7805 regulator chip. They are tape-format-compatible, or at least they are when used on the QL, in that I've never had more than the usual problems reading tapes recorded on other QLs and vice versa [1] The head is supported only by the electrical connections soldered to the PCB. Alingment consists of moving the PCB on its mounting screws. Typical of Sinclair crap, I'm afraid [2] :-( [2] I've said it before, but I'll say it again. The QL, IMHO, cut just too many corners. Had it sold for, say, \pounds 600 (rather than \pounds 400), but had had decent serial ports, a better keyboard, and a disk drive, then it would have sold rather better I suspect. -tony
