As the electromagnetic integrity of my 48g has just transited the River Styx I must replace it, perhaps with a 35s. But the photos I've seen seem to show a sparse display: Could anyone tell me about it? Does its decimal point consist of one pixel or a square of four? How visible is its display's comma? I can find no actual 35s here in town available for a close inspection, but there are some 17bII models. How does the display of the 35s compare to that of the 17bII (whose characters I do like)

Woody, the LCD of the 35s is the same as the revised LCD of the 33s. The decimal point is one round pixel, for the decimal comma a second pixel of special shape is added. It is very readable for me, though unary minus is displayed a bit strange (elevated), and the theta used in polar notation of complex numbers is very close to the digit 8. Please note it's not a dot matrix LCD like in 17bii but a custom display with 2x14 characters (of 7x5 pixels) plus some special indicators above of these 2 lines. I do not own a 17bii but a 42s featuring the same display type - contrast on the 35s is far better than on the 42s IMHO. The 35s's glass cover is very reflective, however.

Thanks, Walter. I'll go ahead and order one. Your mention of the 42s brought back some great memories, though its display did require constant contrast-tweaking; I'd still have it and be using it today were it not for the scumbag (an unknown scumbag who probably couldn't manage even a TI) who stole it. My first HP, a 15C, is still with me but as a treasured antique, my 48g just poofed-out this week, and my one other, a 49g, I finally shipped back directly to Carly (the two seem to make sort of a match, don't they?) with the suggestion that she befoul her wastebasket with it as I did not wish to sully mine with such a piece of junk. Let's hope that the folks over there have reset their goals to the path of excellence which they once owned.
