We here at Genial are looking into the possibility.. 99SG> thank you.. ..JEFF> Any follow up? ..JEFF> if not who wants the next question? ..Paul-G> Do you have a FORTH running in 9640 mode yet? ..PaulC> paul gray was next ..PaulC> FORTH is one of those projects which has been finised for like "forever", just don't have any docs for it ..PaulC> I think I finished the FORTH from MDOS last October.. ..PaulC> ga ..Paul-G> Any idea on a when ..Charles> ? supp ..Mike> ../sen my9640 hi ..PaulC> well, I need to get one of the people who volunteered active on doing the DOCS ..Mike> something is not working for me tonight ..Mike> sorry 'bout that ** 99SG just joined "TI NET SPECIAL 99/4A & 9640 CONFERENCE" (13 members now) ** ..PaulC> can be released anytime, thought I don't want to release it w/o new DOCS ..PaulC> ga ..Paul-G> < No 9640 here (or plans to buy one) or I'd help.. JERRYC> ? followup ..Paul-G> done ..JEFF> ok charles is next.. ..Charles> Was the forth planned as a commercial or fairware? ..PaulC> it was planned as fairware, except that I've stopped giving software away, so it will NOT be fairware when it's released.. ..Charles> Okay.. next ..JEFF> Jerry? ..PaulC> 9640 specific software is even less fruitful than TI99 software (which has been ok at times) ..PaulC> ga JERRYC> Which Forth standard was it? 83? ..PaulC> FORTH 83 JERRYC> Do you have a vendor lined up? ..PaulC> with some extra bells and whistles to save standalone FORTH applications ..PaulC> which will run from MDOS without the FORTH main disk ..Paul-G> ?followup ..Paul-G> nevermind ..JEFF> ..PaulC> no vendor yet......will look when I am ready ..PaulC> ga ..JEFF> FOLLOWUP PAUL? JERRYC> Thanks ga ..Paul-G> No, 4{e answered it, the 4th system disk won't be needed for applications ..Paul-G> C ..JEFF> GO ..Paul-G> If you see the need, or feel inclined, I'd like to see a better Forth for the 4/a.. ..PaulC> any more hardware-technical questions? ..PaulC> -pg 99SG> ? ..JEFF> Go 99 ..PaulC> 99SG> will dos 1..02 allow the myarc fdc to bypass the write verify? ..PaulC> all versions of MDOS have had that ability ..PaulC> ..PaulC> in fact, the write verify can be turned off on any disk controller attached to the 9640 ..PaulC> ga ? ..> ? ..Joe_S> follow up ..JEFF> Any follow up/p Randall? 99SG> i did the mod that lou told me about and he said that it would only work with ok 99SG> the 80 track eprom.. in dos 1..01 ..PaulC> all disk i/o on the 9640 is independent of the controller card you are using ..PaulC> it's just that the type of controller you have determines the default mode of 99SG> how can you turn off the write verify then? ..PaulC> operation under MDOS, the default mode can be fixed with a patch TELEDATA>> ur after Joe's followup.. ..PaulC> in fact, a CORCOMP or TI controller will _correctly_ support an 80 track disk drive under MDOS, with the appropriate patch ..PaulC> randall, you ..PaulC> need to know where to patch the code (information which I do not have at my fingertips right now!) 99SG> thanx ..PaulC> ga ..JEFF> ok Joe, follow up? ..Joe_S> when you do a copy, does MDOS write and vwrify a sector at a time? ..Joe_S> if so can it be speeded up? ..PaulC> if verify is on, yes.. ..PaulC> there would need to be a copy program with more intelligence ..PaulC> which, to my knowlege, has not yet been written.. ..PaulC> ga ..Joe_S> do you know how MSDOS does a copy on IBMs? ..PaulC> yes, they do a track read, then extract the sector data TELEDATA>> ur up next, cb, when Joe is done.. ..PaulC> the write to a new disk.. ..PaulC> their copy routine was obviously not designed by one of IBM's committees ..jph> ..Joe_S> ok, thanks ..JEFF> ok, CB is next.. Go CB ..PaulC> it looks more like an outside sorta hobby person wrote it, and turned it over to their boss.. ga ..> ok ..> Can GENEVE (using hdcc and hard drive, of course) or will it......be able to run.... ..> a program like R:BASE? what are the limitations of MDOS? GA ..PaulC> peter? ..jph> The limitations? ..jph> The capablity is there ...... ..> YES......commands, et al compared to MSDOS ..jph> to run large complex programs .. .. .. ..jph> however it takes a person with large amounts of time to ..jph> create such complex applications .. .... and there ain't many people ..jph> like that around these days .. .. .. so I'd put the limiting ..jph> factor outside the hardwae and system software.. ..PaulC> the MDOS PAB for file access doesn't support more than 32768 sectors in a file, though.. ..jph> (more than enough for most app's, no?) ..> EVEN WITH A 20/30/40 MEG DRIVE? ..jph> Even with a 20/30/40 meg drive.. ..> EEK! ..PaulC> a drive can have more sectors than that, just not a file.. ABEARD> (8 megs, I calculate) ..Mike> Before you get upset over that, try to figure out _why_ you would want ..jph> should keep most people happy........especially since a dB could be ..jph> split across multiple files .. .. .... ..Mike> a file over 8 meg ..Mike> even though there are some ibm databases that do that, ...... ..Mike> how many geneve owners would at all desire to be able to use such a ..Mike> large database or file.. ga ..> ok......thanx! next ..jph> (give me the application where that becomes a problem......we'll find ..jph> a solution......I promise) ..JEFF> Any followups? ..jph> ..Mike> A safe promise, I think :-) ..JEFF> Any questions? /SEN JPH what about myword? MORE BELLS AND WHISTLES? ..jph> a few changes are on the way .. .. .. ** CSHOPPER just joined "TI NET SPECIAL 99/4A & 9640 CONFERENCE" (13 members now) ** ABEARD> ? ..jph> a SETPATH command has been added so that ..jph> you can set it to load from any device name .. .. .. ..jph> SaveOptions remembers a few more things .. .. .. .. ..jph> the formatter is much better behaved.......... ..jph> it won't conflict with JJ's MENU program anymore .. .. .. 99SG> ? mike ..jph> and the REMINDER feature is now functional.. ..JEFF> After al, Randal.. ..jph> ....and hard drive catalogs are fully supported.. ..jph> I think that does it......oh yea .. .. .. ..jph> The delete and move lines commands are now noticably faster in most ..jph> cases.. ..jph> (that is really all I can think of) /SEN JPH TIS 'NUFF! ABEARD> JJ's menu program? Did I miss something? (what's that?) ..jph> JJ did a version of his MENU program for GPL mode that resides at >6000 ..jph> which MYWORD liked to kill .. .. ..it now lets the cartridge space ..PaulC> the 9640 is finally starting to shape up.. ..jph> survive a normal session.. ..Mike> Unless you use the tility loader.. ABEARD> Oh.. Tell me, is there any way to defeat the keyboard buffer under mdos, Uunder gpl? ..jph> Thanks for the Reminder Mike.. ..Mike> Which may not qualify as normal.. ..PaulC> al, you can always disable the key interrupts and do your own keyboard scan ..PaulC> it's the only real way to do it.. ..PaulC> esp.. since the keyboards have their own buffer internally.. ABEARD> I get concerned doing things like that (too conservative).. It may not work on the GENEVE II ABEARD> Can you comment on the status of the GRAPHICS functions in the library (e..g.. windows?) ..PaulC> hmmm......doing a mode 1 or mode 2 scan will flush the buffer for you ..PaulC> for a more interactive keyscan ..PaulC> GRAPHICS......no clue here at all, that one would have to be fielded by a MYARC representative ..jph> The last official commentary I recall hearing on that topic ABEARD> mode 1 = left side of keyboard, mode 2 = right? ..jph> came in the form of a MICROpendium editorial last month, I believe.. ..Mike> right ABEARD> ok.. ga ..JEFF> ok, Randall was next.. 99SG> mike: i saw a pre leased version of mdm5 and it supported pathnames for 99SG> floppys.. will dos support this also? ..Mike> Peter? ..jph> that is planned for DOS at some point in the future.. Don't ask for ..jph> time tables though.. ..jph> (I don't expect it will be a much used feature so it hit the ..jph> bottom of the list) ..jph> ga ..JEFF> Any Follow up? 99SG> why was it added to mdm5 if it isn't supported now? ..jph> it is supported on the 99/4a NOW.. 99SG> will it work in gpl? ..jph> no 99SG> thanx.. ga ..JEFF> Ok, any other questions.. Let's give Paul a rest.. Give some to Peter and Mike.. ..jph> JERRYC> ? jph ..JEFF> Ok, Jerry ..jph> jerry? JERRYC> I think I lose the last char of an 80 char line when I reformat in MYWORD??? ..jph> hold on and I'll check ..jph> nope.. it works fine for me...... JERRYC> Hmmm ..jph> I'll keep trying to mess it up from here while the CO continues.. JERRYC> I got it while editting CO transcripts that do not word wrap ** RROSEEN just joined "TI NET SPECIAL 99/4A & 9640 CONFERENCE" (13 members now) ** ..PaulC> ..jph> ....Jerry it happens if .. .. ..jph> the word is only one character .. .. .. I suspect this is a TI bug as I ..jph> never played with the reformat routine .. .. .. will have to look into ...... ..jph> interesting bug sir.. JERRYC> Thakns Peter JERRYC> "Thanks" ..JEFF> Of course, Jerry will find it! ..JEFF> Any other questions? RROSEEN> ? ..jph> (Jerry found some of the more interesting early MYWORD bugs too) ..> ? ..JEFF> Ok, we will be having General questions shortly.......... ..JEFF> but we will give a few more minutes to Tech issues........ ..JEFF> Go ahead Richard and CB is up after RR.. 99SG> ? paul RROSEEN> CAN WE set a standard for needed change to video port on Geneve RROSEEN> several RGB monitors seem to not work with composite sync RROSEEN> therefore a standard pin for bringing out the HSYNc from the 9938 RROSEEN> then I have a simple circuit to derive the vsync from composite and hsync RROSEEN> I gather that Lou will not have anything to do with it RROSEEN> that users will have to do something themselves ..PaulC> hello? ..PaulC> what is the current question? ..PaulC> or is there one? RROSEEN> what about 800k 3..5" floppy format ..PaulC> oops.. ..PaulC> I was /sending my answers to richard ..PaulC> ga ..JEFF> Anyone want to try for an answer or a statement? ..PaulC> if richard wants to do a video port expansion for the 9640, fine.. RROSEEN> I think the question was more for the users than an individual ..PaulC> I'm not worried about the monitors which don't work JERRYC> ? followup ..JEFF> Jerry, GA JERRYC> Paul do you have any views on a safe or "natural" way to do such an expansion:?" ..PaulC> 1) remove 9938 from socket ..PaulC> 2) solder a wirewrap wire to HYSYNC (and VSYNC if you're psyched) RROSEEN> sen ti994a most machines don't fill vacated positions with MSB of W did not notice ..PaulC> 3) bring the other end's of the wrapwire out to the edge of the card RROSEEN> where is vsync? ..PaulC> 4) don't use video connector to attach the cable for your monitor TELEDATA>> I didn't forget u.. RROSEEN> dab of solder on solder side would be fine /SEN TELEDATA I know! ..PaulC> 5) solder the video cable (all wires) directly to the Geneve arm (or course, voiding the warrantees) and plug 9938 back into socket ..PaulC> ga ..JEFF> Rich, if you have a comment, please wait until Paul is finished.. ..JEFF> Jerry, any follow up? JERRYC> Jim Horn is very interested (as you know) but NOT in voiding warranty! RROSEEN> where is vsync or rather is there vsync ..PaulC> it's cuz they compare for 85 instead of 86 JERRYC> Thanks ga ..PaulC> oops ..JEFF> Any comment Rich? JERRYC> (This is his Mitsubishi problem) RROSEEN> yes RROSEEN> is there a vsync pin? 99SG> ? reply ..PaulC> csync works as vsynch if you set the 9938 modes correctly RROSEEN> that saves alot then only one wire needed.. ..PaulC> yep ..JEFF> ok, Randall U have a reply ? ..PaulC> ummm......i have another thought ..jph> i gotta run for a few minutes (phone conflicts....) will return ASAP ..PaulC> if you remove the 12 volt regulator, you can tie the hsync wire to the 99SG> the tech data says that pin 6 is a tristate and that highlevel is csyncc 99SG> and low level is vsync.. ..PaulC> regulated +12 pin and have it come out on the pin which is usually used to power a TI modulator.. ..PaulC> of course, you have to remove the filter capacitor from that same line RROSEEN> you read my mind exactly!!!!!!!! ** MIDATL99 just joined "TI NET SPECIAL 99/4A & 9640 CONFERENCE" (10 members now) ** RROSEEN> the transistor driver is needed ..PaulC> 99sg: lowlevel is VSYNC _input_ ..PaulC> used for GENLOCKING ..PaulC> ga 99SG> yes! ..JEFF> Randall, did you finish your reply? 99SG> sorry i overlooked that paul.. RROSEEN> vsync out can be derived simply from comp sync using hsync ..PaulC> it's called one 74ls00, richard.. (use two of the gates) ..PaulC> ga RROSEEN> one monostable 74ls 121 DAVEBROWN> - signed off - ..JEFF> Ok, we have any other followup on this? ..JEFF> If not, CB is up next..
