Don,
I have two HP 200LX computers that I still use from time to time. I think I have a half a gig card in the one - amazing when I think of the IBM XT and it's huge 10 MB hard drive.* In any event the HP 200 LX is very well made and has lasted this long. I wouldn't think there would be a huge difference between the Singapore Rollie 35 and the German 35 but I would know for sure. I own a German B 35 and that is my only frame of reference.

I have a vague recollection that one of my LX models, (I went through the 95 and 100 before ending up with the 200) had to have an in-warranty repair.

I received from Thaddius a couple of years back a free software patch that's supposed to allow it to see much more than the 10 MB I have in it now. I know for sure that it didn't see the microdrive when I tried that and have been afraid to install the patch without more communications from them.

Anyhow, do you have an add-in driver for your expanded memory? (Thaddius used to add memory and increase processor speed, but they did it by tearing into the guts of the unit and I just wasn't comfortable with that.)

I have leaned to just use alkaline batteries in the unit. Rechargeable batteries, at least a few years ago, would only last a few cycles of charge/discharge, and had a lower capacity, by far, than regular alkaline batteries. I now keep it on AC power. I have a nice battery check program that works well and I use that from time to time.

The HP product I miss most is my HP45. It developed a display problem and after a lot of thought I just had it destroyed when I was packing to move in October, 2007. I haven't much exercised the RPN and scientific features of the 200LX but it's not as nice as those on the 45 which has a better keyboard for that.

When I owned my own company I was able to upgrade as new things came along and went through all the Sharp Wizards, and all the HP products with the 200LX being the last. I do have an 18C and that's the one sitting on my desk most of the time.

Back to the issue of estimating distance, it's been a long time since I had a camera that required that but when I did, I could do very well. I also went for many years without an exposure meter, just using the paper that came in the film box. I still have (just re-discovered) my GE 8DW58Y4 which is a little sick, but it served me well with my 2.8C when I lived in The Netherlands in 1963. The needle has no pivots, just held by the springs, and it tends to fall against the scale in some positions. It has always seemed to have a bad cell but it gave me good exposures. I don't really know the model number other than that long one just above.

*About hard drives-

I used to sell Molecular brand computers. They had a 30 MB hard drive that was about the size of a VW engine. I also designed an adapter to add hard drives to that first Xerox CP/M computer. In connection with that I contracted to buy, from a new company, Miniscribe, 1,000 10 MB Rack and Pinion drive (Their special claim to fame) HD's for about $1,200 each wholesale. I never bought them all but those were the days when 10 MB was a big deal.

One really has to think about this in these days of cheap 1Tb drives and 64Gb (and larger) finger-sized flash memory. The prices for new computers at Fry's lately have been rather shocking: one can buy an economy computer for not much over $200 and a deluxe computer for well under $1000, that is, complete with KVM. These also have RAM in huge quantities which would have been unthinkable only a few years ago.
