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
