Mika73 Posted March 31, 2019 Share Posted March 31, 2019 It crash and menu won’t show up like it should. I have new cartridge port. Speech expansion and 32k sidecar memory work ok. Any idea what should try next? Sent from my iPhone using Tapatalk Quote Link to comment Share on other sites More sharing options...
blackbox Posted March 31, 2019 Share Posted March 31, 2019 (edited) May be worth mentioning that with a speech synth between the console and 32k ram, the 32k needs its own power, as the speech synth does not pass it through. The FG99 and 32k without speech can manage without a separate power source. I have had similar corrupted screens to that shown at http://atariage.com/forums/topic/289705-final-grom99-wont-work-if-speech-expansion-is-connected/?do=findComment&comment=4248384 and it seems to be due to mechanical module seating problems - the console module seating was never intended to have a module pressed on from the top, and no matter how carefully I press those switches my FG99 module seating becomes tenuous, especially leading to GROM errors, but also the screen corruption as shown above. I am considering taking the FG99 out of the module case so that I can seat it more deeply into the console! (This thread seems to be duplicated? Clean up?)

Mika73 Posted March 31, 2019 Author Share Posted March 31, 2019 I understand it’s ok modify speech synth feed power for 32k. It’s modified with jump wire. Sent from my iPhone using Tapatalk Quote Link to comment Share on other sites More sharing options...
Mika73 Posted March 31, 2019 Author Share Posted March 31, 2019 After clean those connectors, multi carts won’t start and Parsec cart has cracking speech. Don’t know what do. Sent from my iPhone using Tapatalk Quote Link to comment Share on other sites More sharing options...
ti99iuc Posted March 31, 2019 Share Posted March 31, 2019 (edited) Have you already tried to disconnect the Speech and see if the multi cartridge works? Had you possibility to try the speech on another TI99? Edited March 31, 2019 by ti99iuc Quote Link to comment Share on other sites More sharing options...
Mika73 Posted March 31, 2019 Author Share Posted March 31, 2019 Final GROM did work without speech yesterday. But today can’t get multicarts work anymore and speech is cracking with parsec cart. I don’t know what’s wrong. Can it be bad PSU or power board inside machine... Sent from my iPhone using Tapatalk Quote Link to comment Share on other sites More sharing options...
Mika73 Posted March 31, 2019 Author Share Posted March 31, 2019 I did remove sidecar 32k memory. Now Parsec speech work again. Insert mem back and speech still work. I did try multicarts. It takes 3-5 power on/power off switches get multicart menu. Sent from my iPhone using Tapatalk Quote Link to comment Share on other sites More sharing options...
blackbox Posted March 31, 2019 Share Posted March 31, 2019 I understand it’s ok modify speech synth feed power for 32k. It’s modified with jump wire. Sent from my iPhone using Tapatalk There is a lot in the FG99 (and the multicart) and if the console power supply is having to meet all the demand there may not be enough power to go round, which could cause the fairly random effects you describe. If you have problems with no 32k connected, and just speech plus parsec, that suggests a problem with the module socket. The module actually plugs into a socket which in turn plugs into a second socket at right angles and both sets of connections have to be good. The internal socket needs the console to be taken apart. There was also often a rubbery "cleaner" the module pushed through to get to its socket which was supposed to clean the module contacts but ended up spreading dirt on them- most of these clip on parts were removed. So much opportunity for poor contacts... Quote Link to comment Share on other sites More sharing options...

Mika73 Posted March 31, 2019 Author Share Posted March 31, 2019 I did order USB cable from China it was maybe 2€ shipped. Let’s see if external PSU makes any difference. Sent from my iPhone using Tapatalk Quote Link to comment Share on other sites More sharing options...
Asmusr Posted March 31, 2019 Share Posted March 31, 2019 I had the same issue: speech not working with FG99 + speech synth + 32K without adding external power to the 32K. Quote Link to comment Share on other sites More sharing options...
