Bad LCD?
This can be fixed! It is not too difficult to do:

Thanks !
We know the Robert BARUCH’s products.
So far, I’ve saved 4 pockets (1 PC3, 1 1251, 1 1211 and 1 1245).

Tout est bon dans le pocket.

Thanks for the Books, Robert !
I also saved a PC-1255 with Baruch's LCD

It looks like my latest order from Robert has been lost in shipping. he now doesn't ship to the UK at all. I don't suppose anyone has any Sharp EL-5100 LCDs they would be happy to sell me? Or would be happy to buy them for me and send them on to the UK with a reliable shipper? All costs re-imbursed, of course.
regards
Andrew

Re: Sharp PC-1211/TRS-80 PC-1 Software
Bonjour,
I really wanted to thank engelen for providing us with these links to all this excellent documentation concerning the TRS PC-1 and SHARP PC-1211.
Thanks to these links, I spent a great Sunday afternoon programming my old pocket computer. Of all the programs listed for these documents, I found one that particularly capture my curiosity.
It's a pearl!
Why such a complicated program. It can only determine divisors of integers up to 129 ?? J'ai dû mal comprendre. Une analyse poussée du code m'a permis de comprendre que ce code n'est pas limité aux entiers inférieurs à 129, may qu'il déterminer et mémoriser jusqu'à 129 diviseurs de l'entier saisi.
When I received my PC-1211 in 1981, I did not have all this documentation and so I used it and learned it to program with the help of the user manuals and the application booklet that I found in his box.
Today by dint of helping each other at MPO, programming light, simple and effective has become like a kind of reflex.
This program, written twenty years ago, can determine the divisors of very large numbers. Although using some trick and displaying the divisors two by two, it is sometimes necessary to wait a little before seeing the final display of the count.
And you are going to tell me:
"But C.Ret, your program isn't fast and it doesn't memorize the divisors. If you forget to write them down, you have to start all over again and start over. The program you're laughing at is much better and has the huge advantage of making a recappé."
And I believe you would be right. So I visited my new friend (the one who's youngest brother costs 23 €/month to chat with in good French) and together we set about correcting Jim COLE's program.
I spare you the hundred pages of the transcription of our conversation and present to you only the product of our common work:
With little optimizations, a generation wheel of pseudo-prime factors co-prime of 2, 3 and 5, a construction of the list of divisors by selective and multiplicative duplication, a merge sort in place by key transfer, this small code, very simple in its principle and shorter than that of Jim COLE, presents the divisors to you sorted in a few minutes for all INTEGER between 1 and 99999999.
(Beyond that, some tests must be modified to avoid very troublesome rounding errors).
Try it, it finds the 18.# divisors of 987654321 and prints them in order in less than 5 min OR the 128.# divisors of 8946168 in no more than 1/4 hour.
Well, it's the least we can do to pay homage to this venerable calculator and make it possible to draw all its power.
Of course, today we no longer program in the same way, the machines themselves are capable of helping us.
