... Currently it is easier for me to deal with disk images, since I can mount them directly from an SVD (Semi-Virtual Disk Drive). Terrific gadget and one of...
So Steve, Why don't you tell us more about this SVD you are using with your TI-99/4A? Where you got it? How much it cost? What its capacity is? Et cetera.. ...
I onced looked into purchasing a SVD, however its cost of $110.00 was a little high for me because one could purchase a complete used TI99/4A system for around...
Ah! Not quite the device I hoped it would be, especially at the price you mentioned, considering a 512MB CF7A+ Sidecar with 32K & PIO is less than $70.00....
Although, for some who would just use it as a means to transfer TI FILES to/form a PC maybe acceptable or more convenient and easier to understand and use? ...
I think it was really originally made for the Apple II Users and happened to ported over other formats like the TI99/4A. However the TI99/4A world has TIdir to...
Bill, I "reviewed" it a couple of years ago (right here), when the original developer gave me one to test it on the TI. The original site is pretty much dead,...
Some questions; starting with the easy ones. :-) What happens if ... 1. we read past GROMbase + >17FF (beyond the 6K)? What data is returned via GRMRD, and...
... Yes, one of the people active in comp.sys.apple2 and with Heath/Zenith machines did another run. I paid about $75.00 for the board and put it in a box...
... Here are my best guesses, without an actual TI-99/4A to check the answers... ... If you set the address below >1800 then keep reading across the border,...
Hello Thierry, thanks for your information! ... Yes, right. My problem is that I do have a TI console, but in a cardboard box. The Geneve in my P-Box does not...
... I seem to remember reading somewhere that the first byte read from a GROM is garbage... the console ROM does a dummy read from GROM before starting the...
Erm, if there is, I can't find it... Sure, there is ANDI (and immediate) but won't work for me, as the operands to be anded are in memory. I want to do AND...
SZC and SOC correspond to AND and OR, it uses a mask to allow you to select the bits that are changed. I rather like it. Plus, as you say, there is always...
Well, R1 is all 1's (this is your mask) R2 is >DEAD SOC is an OR So you will set R2 to >FFFF A SZC will set R2 to >0000 (reset all bits in dest that match the...
So if I invert the mask, I can effectively get an AND? Yes? So, ... AND ... = ... LI R1,>001F LI R2,>000F INV R1 SZC R1,R2 (answer in r2) Would that do it? ...
I have to ask "Do you mean what you say?" Are you trying to get only the right-most nibble of >001F? In that case, you would be ANDing with >000F ( >001F AND...
Eh? :-) 1f AND f=f f and 1f=f same thing... I don't see how the order affects things? *even more confused!* ... From: ti99_forever <ti99_forever@...> To:...
I'm thinking of maintaining the mask and where the result is being stored (not clobbering the mask). Usually, when you AND with a register, you want the...
Ah! Ok, that makes sense! Ok, just did a quick example and single stepped it with Millers Graphics Explorer (awesome program!) It works! Thanks man! (my self...
Personally I think I would rank the processor series that I've programmed in assembler something like this: 1. 68000 2. 9900 4. Z80 5. x86 6. 6502 So in that...
Hmm, that is what my list would look like (if by 68000, this includes the 680x family). I haven't had *much* chance to actually program in the others, but have...
There has been a slight change in plans for tomorrow's Chicago TI show: it will be coming from the TI Treff in Paderborn, Germany. I am here(although my...

Hi Hal, unfortunatly can't stay in Paderborn for the whole weekend. But do plan on visiting the TI Treff tomorrow. It's a 4 hours drive for me (I hope :-) Well...
