This dialogue sent me back to your Flickr site and that is indeed an interesting collection!!

I see you have the 1AAAA version of a Titan and the VER$ shows that old ROM, the IL as 1A and MTH 1A too.

There are stories about the MATH originally being intended to be in the standard product, as opposed to an option, which makes me ask…. The math module in your device, is it built in or did you plug it in “for shows”?

I know it can be built into the free slot with ROM & RAM, I have done it, but maybe there actually was a prototype which had it from R&D “labs”

Hi, The Math module in the device is just a regular production module - I've put that in to play with it along with a 32kb module. The VER$1AAAA seems to be a completely functional prototype. One of my favourites! Cheers, Keith
