I just obtained a Proto 1 F3 ABA set. (Looks like it was a shelf queen...no wheel/roller marks! Nary a scratch!) Installed a BCS right away. Powered it up and it seems to be fine.
However... It's been quite a while (10+ years?) since I last purchased a Proto 1 diesel, and this new addition reminds me of a quirk in the early QSI system;The bell can only be actuated in the neutral mode...not while the engine is in forward or reverse mode.
Yep, I remember that. And after a quick looksee of the manual troubleshooting guide I see that the solution is a "Memory Chip Upgrade".
So, my question is: Are these Proto 1 (QSI, F3) Memory Chip Upgrades yet available? If so, from whom? MTH? QSI?
I know the obvious response might be 'Why don't you call MTH and find out?' Well, forgive my impatience...I haven't anything better to do this evening (MTH has gone home for the day) than throw this question to the forumites. Tomorrow, pending your response(s), I will probably do just that.
(BTW, whereas Proto 1 was designed, apparently, to work bell and whistle with only a whistle button on a transformer, I am using MRC's Duals with separate Bell & Whistle buttons. All of my other PS 1 diesels apparently have the upgrade chip...they respond properly in any mode.)
Thanks for taking the time.
