Hello, Iqbal; long time no talk...
Are you using SUBDIV yet? I was 'organizing and cleaning my attic' (my house has no attic, just a figure of speech...) and found many program listings, amongst them what seems to be SUBDIV´s last version. Good days, though...
Thanks for your mentioning the soccer (football?) world-series cup. I just hope our country, meaning people and government, makes to deserve it... There are many major problems to be fixed in Brazil prior to welcome tourists all over the world the way it must be done. Well, time will tell. I´m an optimist, just do not believe in miracles, I believe in people´s will and hard work. Miracles work well in the big screen, not that much in real life.
About the HP48 and the leakage: I considered that, at least, we'll have the alkaline leakage being diluted in distilled water, reducing its action for the moment. My advise (and this is something I'd do, actually) would be to remove the batteries and dip the bottom part of the calculator in distilled water till the water covers the battery compartment. Gently shake it and allow the water to pass through it, dissolving the alkaline solution. I'd repeat the process at least three times, with new amount of distilled water. THEN... I'd allow it to dry a little bit while setting the arrangements with Randy to send it to fixthatcalc d8^)
Once, I was given an HP48G that stopped working for good. I opened it and part of the internal metal frame was corroded by leakage (the owner had told me about that). The problem is that the leakage also corroded the carbon-based tracks of the flex keyboard circuit, hence the nonworking condition. I did not have conductive tape, but I decided to try to rebuild it with conductive ink, only to see what happened. I did not succeed putting it to work, though...
Not much of a help, but at least I cleared some points out. Thnaks, Iqbal; good reading from you.
