So this board found it's way to me not working of course, It had some previous repair work done where the chips had been out on the topside and replaced the legs had been soldered to what was left on the pad, I supose for quickness but made it very difficult to remove the chips this time round this end pin the track was broken right where it met what was left of the pad, and a wire was put under the board to replace it so this is right under the battery! place where most damage is likely to occur, but nothing had been done BUT shine a light through the board and........ all becomes clear! yes a broken via track! took me about 3 hours to remove everything and clean up the pads, a good few missing on the top of the board where someone had removed the chips previously, my removed ones that had never been out but still had the crystallized solder came out fine eventually. I have no idea what solder was used but it seemed to have a very high melting point and some really nasty flux in it! never smelt such horrid flux before! but the board is starting to look better now and cleaned up good ok so now the track repairs can begin! starting with the ones under the battery! just the one was rotted through but all via hole tracks done for future reliability

Mike, I decided to put wires on the top tracks so they can pass through the IC holes to the bottom side where the pads are intact and are folded over flat on the pads, this gives room for the ic legs to also pass through the holes and be soldered on the underside, this way there is room to desolder the chip legs free should they be needed to be removed in say 30 years time! I did think I might use the rivets (or eyelets as there known in the industry) but I am still waiting for the tool to arrive that folds them over nicely and this makes the holes smaller with less leg clearance and more difficult to remove chips if needs be! It appears the person that removed the chips in the first place managed to damage every 0v and 5v tracks on the topside to those removed chips! top pads just ripped off! I bet the old "screwdriver under the chips and a big push" trick was used to get them out! the ones that had never been out which I removed were fine! no track damage! as you say Bob more introduced faults to repair! Anyways this is how the board looks tonight on the top so far, more still to do and a lot of track metering to do too! but that's for another night......

I can't remember now, as you can see the videos are a few years old and I gave up doing anything more with erio machines and I don't have that rig set up now, so cannot remember the keypresses orhow and when, perhaps someone may come along that remembers

its a normal pc with normal ps2 keyboard and mouse ports from around 2004 which runs 2 screens which was very advanced for its day, but easily messed up if only one screen is connected, it was the way it was back then! yep thats me

Great. My girlfriend loves playing these in the pub. This’ll save her a few quid. Cheers!

Good to see a future HTS layout in the making.....
