RE: HEPAX-0C Prototype version ROM images.
Please note I have created a new thread for the HEPAX treasure chest ;-)
- and when I get some time I will also provide some insights in how the HEPAX module came about. I have checked with Sten Vesterli and he is not able to locate the original drawings of the HEPAX module - so we must assume this information is lost. We may be able to backtrack memory chip connections on the breadboard if this is important. KimH came with a working 9114 drive and we determined my drive was non-functional - as his battery did not bring my 9114 back to life... All the code was made by hand - first written on an A4 sheet of paper and when I thought it was complete, then I entered it on the HP-41 via the ASM3 assembler. I will write about this another day ;-) Regards, Steen |
