Hi! Thank you for your help, unfortunately the changes that needed to be done are pretty coplex, although I understood the instructions changes properly, thanks! P.D: As a matter of fact, it amazes me that, the code the other user was trying to migrate.. is the same as I am, just looking at the portion you converted. So I'm working on the same type of machine, in another place, 7 years later :D
HI! I face the same issue as this thread: http://forums.mrplc.com/index.php?/topic/22081-iems-instruction/ but I will be starting this new one. I have to migrate a C200H to a CS1H, but I'm facing issues with the IEMS instruccion; it does not exist for the CS1H. I pretty much know how the instruction works, but I don't really know how to migrate it. I'm also facing some other handicap: my CS1H cpu don't have 3 EM banks as the original C200H, but I have to cope with it, can't change the CS1H cpu. I was thinking in reserving three 6143 word chunks in the DM bank to emulate the EM banks so I can move the index register between those three "banks", but I don't really know how to change the instructions for the CS1H. I've added a pic, some help would be welcome. Thanks.
