It was mentioned that the TMS99000 family of processors (e.g. TMS99105) have stack related instructions (or is it an addressing mode?). I checked the data manual, but I must be overlooking something. I can’t find anything related http://bitsavers.informatik.uni-stuttgart.de/components/ti/TMS9900/TMS99105A_and_TMS99110A_16-Bit_Microprocessors_Preliminary_Data_Manual_Nov82.pdf Do we have any example where stack manipulation is done on the TMS99000 family of processors?
Hello again 99ers! I've got some more noob questions to bring to the table . Firstly, I noticed that when I dimension a string array in BASIC that stack is set aside for it. However, it appears to be a weird ~2.8 bytes per element that it sets aside - what is it putting in memory at that point, the name, location, and dimensions of the array? Also, if the stack fills up, will string variables/arrays start using the 'program' space, or is that when we get the infamous OUT OF MEMORY error? And the stack is HIGH memory, is it not? Now on to the SuperAMS. I have not been able to find much more than a schematic for this - no user docs whatsoever (I've pretty well scoured whtech and the 'net). The RXB manual mentions something about a 'MANUAL-AMS', but I haven't been able to find that. What I'd like to do I make use of this new memory toy (1 Meg AMS) with a couple programs (R/XB) I've got on the burner, but, I don't know how to use it. The AMS demo included with RXB appears to load screen dump files, but the two programs in the works use files of types SEQUENTIAL,INTERNAL,FIXED 20 and RELATIVE,INTERNAL,FIXED 108 so I'm not sure that the approach used in the Demo really applies, especially since I would like to be able to manipulate the data in AMS memory. I would prefer (but perhaps may not be required for my purposes) to able to use arrays (and I mean big arrays ) in conjunction with the AMS, if possible. Well, I know I've asked a mouthful. But I think a good starting place would be to get my hands on a decent manual for the AMS card - I don't mind doing some reading . Thanks for reading buddies!
