Early "tall boy" Gemini-II

David C. Partridge Member Profile All Messages By This Member #23245 开云体育 Does anyone here in UK have an early model “tall boy” Gemini-II controller that I could borrow for a while to checkout a reported problem with the Level 6 firmware? ? Cheers, David ?
Graeme Coates All Messages By This Member #23246 I have one yes (I think! Assuming there's only the original and the Mini) - how soon do?you need it? (I'm on crutches so I may not be able to get it out of the dome in short order - if someone else has one it might be better, but happy to help if needs be).?

It *may* not be necessary – I’ll know by end of the weekend if I do need it. ? toggle quoted message Show quoted text From: [email protected] <[email protected]> On Behalf Of Graeme Coates Sent: 03 February 2023 21:13 To: [email protected] Subject: Re: [Gemini-II_io] Early "tall boy" Gemini-II ?

Brendan All Messages By This Member #23248 David, There are about 3 versions of the “tall G2s”. ? One with the jumpers and RS232 transorb protection, one without the jumpers but still has the transorbs and another without the transorb on the RS232 chips. ? Some earlier Tall G2s had some mods to the H bridge (capacitors and resistors fitted) to stop the motors jumping at switch on. ?Not sure if this was just for maxon motors. ?I think there was a stage there was a maxon motor seperate dsPIC firmware. ??? ?This was “way back”. But the firmware supposedly suits all now. ?But the hardware mods may still be in place.? FWIW? -- Brendan
