Re: DM42 with homemade printer

... as a somewhat typical American I've not even heard of one of them (Andorra). Although it's a very tiny country, Andorra has been featured on my Flags and Anthems of the Countries of the World of the Great HP 48 Enthusiasts web page since 1998! Andorra was only included in this table of HP 48 En...

Re: Machine accuracy

For HP50G 1+10E-12-1 = 10E-12 1+5E-12-1 = 0 If 10E-12 were the EPS for the HP 50g, then 10E-12 would be "the smallest machine value that can be added to 1.0 that gives a result distinguishable from 1.0" (the definition of EPS given in the linked PDF). But it's not the smallest. For exampl...

Re: Machine accuracy

The article says that EPS is "the smallest machine value that can be added to 1.0 that gives a result distinguishable from 1.0". However, the photo of the HP 50g shows an EPS of 7.275957614E-12. But smaller values work too, e.g. 1.0 + 6E-12 --> 1.00000000001 It seems to me that EPS for the...

Re: DM-42 in HP-41 font

Point being, every time I hear “goose” I think about my synthetic routine that ran the goose backwards with droppings. And that reminds me of the many fun HP-41 displays that decorated the HHC 2009 website , such as this one, which includes a backwards-flying goose with droppings! http://hhuc.us/20...

DM-42 in HP-41 font

Ugly and redundant, but it still makes me smile because it's the HP-41CX extended font. And a goose. :)

Re: Random images

These look great! What are you using to create the images and adjust dithering? Two different tools: (1) Thumbs Plus . While viewing an image, press D to change its bit Depth, then select Bi-level (1 bit), then play with the Dither method and the Threshold. (2) PaintShop Pro . While viewing an imag...

Re: DM41x is no longer recognised by Windows 10

I was in the same boat a few days ago. I accidentally tried to load a bad image into the OFFIMG folder, and it choked so badly that I had to unplug the cable to regain control, but the FAT was corrupted. The solution was easy: Shift 0 (SETUP), 5 (System), 2 (Enter System Menu), 5 (Format FAT Disk). ...
