BWB appear to had provisioned for an illuminated ident on the smallest glass pane under the mecs, I've finished their job for em and it looks great 🙂 before and after - minor details I know....

A true collector! looks great!! not like people that just buy machines to get barely working as cheap as they can and flog on for profit!

Hi all hope you're all ok 🙂👍 had massive issues logging into my account on here, with passwords resets sent but not received, and not being able to log in view or commenting on people's projects really frustrating 😞 just found a very old note pad with my info on and logged back in, so currently sporting a third leg with excitement! Amazed the password resets didn't mess anything up! Man I'm chuffed it worked, now lots of catching up to do from the nearly 2 years missed 🫣

Definitely a real credit to you!!

I would have thought it would go through a solder bath so all I can think off is maybe the pins were contaminated or they didn't get fluxed? Who knows, the soldering on the whole looks too consistant to be done manually.

This one was a bit odd. There was a fault on the lamp circuit and about 5 lamps were stuck on. When I put the scope probe on the relevant output from the driver chip IC11 (74LS138) the lamps went super bright?? Thinking the chip must be faulty a new one was fitted but no difference! Then I did what I should have done first off which was to visually check the board and I noticed this... It hasn't come out too well in the pic but the top horizontal row of the resistor network pins (centre top) showed two that had never had solder on from the factory!! By the way this wasn't the cause of the lamps being stuck on, a couple of the output transistors were leaking but that's bread and butter stuff.
