Re: HP-41 Emulation Message #4 Posted by mark murphy on 22 Aug 2004, 5:01 a.m., in response to message #3 by Klaus
Hi Klaus,
Sounds very interesting. I was thinking very directly about using the original HP41 casing (ie from non working cheap sales from eBay). Though I'm sure the next part will sound like heracy - use case, Keybd, lcd, battery - instead of standard i/o modules replace with mini-usb. This gives enough room in the case for more Ram, more Flash Rom, two pics (one for display, keyboard and USB - one for 'mainframe' emulation). Replace the back exp ports with 'blanking plate' with the mini-usb port. Reasons, HP-IL dead, I'd rather connect directly to a usb modern printer and my PC/Mac/Palm/PocketPC/Mobile Phone/ USB Storage key. I've had an HP48 since blowing up my 41 at Uni (yes, one internal Rom too many 20 years ago) and it's too big - using a 41cx again has made me realise how great the form factor was! I'd be interested to see what the OTHER Hw proposals where as I've not seen much except Xpander type projects (keep them I've got a a Palm/Pocket PC already). THe great thing with Diego's Clonix/NoVram is the it uses the original Form factor. As an aside - a quicker project might be to get an additional mini USB module (sitting in a rom pac) working in tandem with Clonix/NoVram - would that work Diego?
