Advanced Programming Reference for Monroe 1800 Series calculators

[jefo...@gmail.com]

Dear Colleagues, 

Would any of you have a copy of (or a link to) the "Advanced Programming Reference  Manual for Monroe 1800 Series Calculators" ? Or equivalently for the Compucorp 400 (425G, 445...) Series Calculators ? 

Similarly of interest would be a copy of the "Operating and Programming Instructions" for the Compucorp Model 120, 121, 122 and 125 Calculators" ?

Images of the frontpages are attached. 

Looking forward to your feedback !

The only manual I have found online is the Litton Monroe 1800 300 I-O Writer manual here:

Rick Bensene has a an original of one of the manuals I believe you are seeking, but it is not scanned.

 

I have not seen any correspondence from Rick in a while, I hope he is doing much better.

Dear Don,

Thank you very much for the 300 I-O manual, and the info on the Advanced Programming Manual. I am in contact with Rick and he is looking for the manual in his collection, but is in a difficult health situation. To unload the burden from his shoulders I contacted the group. We will see how things develop, and if no other option emerges, we will wait until Rick is able to continue the search! 

With my best regards,

Jef Ongena

Hello Jef,

Unfortunately, I do not have copies of these manuals, but your request is very interesting. Recently, I built two AI-powered calculator projects that turned out really well. One is a Grade Calculator for students and teachers to track grades and academic performance, and the other is a Destiny Matrix Calculator compatibility focused on life purpose, personality insights, and numerology analysis.

These projects also increased my interest in vintage and programmable calculator systems like Monroe and Compucorp.

I will check some vintage calculator archives and documentation forums as well. If I find any useful manuals or scanned copies, I’ll gladly share them here.

Best regards

Greetings, all,

I have the manual in question, but it has been resisting my attempts to find it amidst a huge stack of documentation that I have to sort through, catalog, scan, and put up on my website.

It is here somewhere, I just have get the time to dig through stuff and find it.  Unfortunately, my health has been giving me a lot of difficulty, and finding the time where I have the energy to spend doing this (after I've done all of the "required" things) is extremely limited.    I will continue looking for it, and the moment I find it I will not delay in getting it loaded up in the scanner, and make it available on my website, as well as notifying y'all here.

I'm sorry that there has been such a delay, but this is the story of my life for the past year and a half.

Best to all,

-Rick
