Shift838 Posted April 13, 2018 Share Posted April 13, 2018 I'm thinking of using the design i found on mainbyte to make a speech in peb plane board. The drawing has one part that is confusing me. See photo. I have looked at Thierry's website too which has the same concept but do not know if it's another LS00 chip or what. Anyone? 1 Quote Link to comment Share on other sites More sharing options...

See photo. I have looked at Thierry's website too which has the same concept but do not know if it's another LS00 chip or what. Anyone? I was building a speech board, based on some info back in the day, on perf board. I know where the board is, to trace that out, but it would be Monday before I can post a possible answer. Someone else probably already knows or can get an answer faster, but I will post it Monday, if possible, otherwise Quote Link to comment Share on other sites More sharing options...
+Ksarul Posted April 13, 2018 Share Posted April 13, 2018 I have an experimental layout for this board that I've been debugging off and on since the 2016 Chicago Faire (health kept my hobby time limited for most of last year, but I am getting back up to speed now). The original and updated versions of the schematic are in the documentation thread. . .and they properly identify the components. That may help you--and it may help my debugging too with another set of eyes playing with it. Shall I send you one of my assembled test boards, Chris? It has all of my known corrections applied to the board already. . .it works, but the sound is still a bit garbled, which tells me it is probably a timing delay issue. I just have to play with some trace lengths to see if that resolves the remaining issues. . . Quote Link to comment Share on other sites More sharing options...

+mizapf Posted April 13, 2018 Share Posted April 13, 2018 The 74LS00 has four NAND gates, so I would guess this is just one of them. What was your question? Quote Link to comment Share on other sites More sharing options...
Omega-TI Posted April 13, 2018 Share Posted April 13, 2018 A few years ago Greg Warner started a project in << THIS THREAD >> for just such as device. It's been long abandoned, but maybe if someone gets a hold of him he might possibly part with the info to get it completed. It's worth a shot anyway. Also with a future TIPI IN A P-BOX this may be very popular. Quote Link to comment Share on other sites More sharing options...

Also with a future TIPI IN A P-BOX this may be very popular. I have reached out to him on it earlier but no answer yet. His if I recall was based on a CPLD and I thought he said he had it very close to be finalized a few years ago. Quote Link to comment Share on other sites More sharing options...
Opry99er Posted April 13, 2018 Share Posted April 13, 2018 I chatted with him not too long ago. He said he was going to come back and get back to his projects... no timetable though Quote Link to comment Share on other sites More sharing options...

atrax27407 Posted April 14, 2018 Share Posted April 14, 2018 Will it have any additional functionality or will it be like the RAVE Speech Card I have in my P-Box right now? Quote Link to comment Share on other sites More sharing options...
Shift838 Posted April 14, 2018 Author Share Posted April 14, 2018 Will it have any additional functionality or will it be like the RAVE Speech Card I have in my P-Box right now? I would like to see it with RTC and for it to be compatible with the Corcomp and MBP clock cards with a switch that can turn the clock on/off so it could be used in the TI or the Geneve (just as a speech card). I think that may be beyond my abilities though. Reason I was thinking of this is because since I acquired the Geneve I have no speech for it without a card and the Rave99 cards are very hard to find.

+Ksarul Posted April 14, 2018 Share Posted April 14, 2018 Here's the schematic I did a while back. Note that there are three errors on it: the PEB pin numbers for D5 and D6 are reversed (D5 should be pin 21 and D6 should be pin 22) and RD3 should connect to pin 42 of the Speech Synthesizer (the schematic shows pin 32, which is wrong). I'll be correcting these in the next data release. A3-PEB-Speech-P1(R1).pdf A3-PEB-Speech-P1(R2a).pdf Quote Link to comment Share on other sites More sharing options...

+OLD CS1 Posted April 14, 2018 Share Posted April 14, 2018 What was that for? Just being nasty? Unwieldy abrasive, perhaps. But I am not certain greg has completed any of the projects he started working on (two to my knowledge.) I know a few people like that, myself... colleagues, actually, and they are known as "flakes" in our community, as well. Quote Link to comment Share on other sites More sharing options...

First, my wife got pregnant, and then we had to move houses a SECOND time, because the landlord kicked us out!!!Anyway, I have finally gotten my TI stuff unboxed, so I have your RAM disk safe and sound, ready to mail back to you. Can you update me on your address please?Once again, so very sorry it's taken this long. Seems like life threw me one curve ball after another, but we're stable now. Still wish I had the opportunity to get back into my TI hobby!Best regards,Greg W. Reply Report marc.hull Stargunner 1,212 posts Location:Oklahoma CIty.
