HP-71 Compu-LS module

[twa14]

Many many thanks to all of you for this, when I first started searching the forums for suitable information I thought omg! i'm only kidding myself, I didn't understand half of the hardware terms. I'm not finished yet as I have not carried out the last steps but am relieved to hear that the text file was good.

I have another project, this time with the HP41. Some years ago I bought 4 smashed up 41's on EBAY from Israel. I was hoping that one would be good enough to convert to a 41CL. This was not the case but on checking the ports found two ROMS installed called "AZIMUTH" they appear to be survey ROMS but I'm not sure. I tried very hard to find information on these ROMS without success. I even contacted the Geomatics Dept. of Technion Univ. in TelAviv but no one had heard of this ROM. I approached Matthias Werli who offered to read out the ROM as I had no PIL-BOX then. I sent him one of the two but it apparently did not arrive. I still have one left and Monty Dalrymple is interested in a copy for his 41CL. So don't go away just yet, I'm going to need some more help.
