Hi, I have 'honeycomb' that are used in the IBM S/3. Any idea what the outer dimensions of a block of 5x5 lambs is ? Or the distance between two lamps horizontal or vertical ? (pref in mm)

It doesn't look like S/3 code. Most used S/3 instruction is C0 87 xxxx (Uncond branch) I have attached all 5100 related files I have. Originally from Christian Corti.

Ok, there is still some misunderstanding how it works. The virtual memory implemented on the model 6 only increased the 'available' memory from 8/16k to 64kbyte. IBM did a very nice job doing this, although it has nothing to do with our BASIC question. Model 6: BASIC statements are compiled...

Mark Waterbury and I have sorted this out some years ago. There is no IBM System/3 machine code emulator in the IBM 51x0. The S/3 model 6 had a BASIC (5703-XM1) See http://www.bitsavers.org/pdf/ibm/system3/plm/LY34-0001-1_System3_Model_6_BASIC_Logic_Manual_Jan72.pdf The compiler generates a...
