Trade Answers for HP71B case Recomendation
Message #1 Posted by RonHudson(USA) on 5 Sept 2007, 12:17 a.m.

Yay! I just got a newish HP71B (just a crack in the glass, not the lcd) no roms, no rams, no card reader, no hp-il verry basic.

First my contribution (since I am new to the community).... I have a little case by Jansport, the number 520199E35040 appears at the top of the care tag. It's almost 11" x 6.5" It has a nice zippered pocket as the last layer on the left, perfect for the 71B. Lots of other pockets, zippered and not, for 'stuff'.

As I said I just got a real 71B from my brother who was not using it. and I have a few short questions:

1)key "q","mod(" how do I tell the 71 I don't want a endline? Can I have it put "mod(<)" where < is an insert cursor?

2)Anyone have a listing of the flags? I can't quite afford the cdrom manual yet.. no job. In school for another year (ITT-Tech) Perhaps some of the important ones?

3)How hard is it to get an HP-IL module? (assuming I don't want to mess with e-pay. A Serial port?

4)How will my 71B like it if I feed it nickel-metal-hydride batteries?

Thanks! ron.

Post a WTB. As for eBay you should find an HP-IL module and an HP82164A HP-IL/RS232 interface within a few months.

My friend Ron, I have PDF of manuals, but almost 40Mb compressed. Let me know how I can get to you and I can send them.

Thanks, Vincze for the kind offer :^) , but, sorry, I must decline.

When I have the cash I will support the museum with a purchase of the CD-Roms needed. In the mean time I am building my own "quick reference" that mostly documents the differences between common basic and HP Basic in the 71. I have gathered quite a bit from the archives.

I was lucky and got a 71B with manuals. :)

key "q","mod(;" - the semicolon shows that the assignment is a typing aid. I don't think there's a way to position the cursor within a typing aid.

Egan's replies to 2&3 match what I would have answered.

I've only had mine for a few weeks, but it seems very happy with a set of the new NiMH hybrid batteries - I'm using Uniross Hybrio, but they're also available as GE/Sanyo Eneloop, RayOVac Hybrid, and I think even a Radio Shack brand. The advantage of these is that they hold a charge much longer even when on the shelf. You can buy two sets, swap and charge/store as needed.

That just put a ";" on the screen... but

key "q","mod("; worked as desired.

Anyone know any other key magic?

Even fully charged, their voltage is just about low enough for my HP-71's to show "Low Batt". A set of alkalines probably lasted at least 6 months or a year when I was using the 71 heavily every day in the late 1980's. Now that I'm not using them so much, a set of alkalines probably lasts two or three years, even in the 71 with HPIL, Math ROM, Forth/Assembler ROM, CMT 64KB RAM, and CMT 96KB RAM. There's no reason to use rechargeables.
