Thanks Bob, Finding the module and taking the picture, I asked myself the same question. At first I thought W&W as I bought quite a lot from them at the time, but then I settled for Educalc. When you asked I had to find the old receipts :-) that was quite a trip down Memory Lane. I bought it june 1983 from "Polyteknisk Boghandel" which is a bookshop still located at DTU in Lyngby, Denmark. http://www.polyteknisk.dk Price in 1983 1925,- DKR which in 2022 would be 600,- USD. /Poul |
