At this point I was going to put new graphic decals on the steering unit, but for now I am just going to clean it up a little and get it functional. Putting new graphic overlays on won’t get done till the end of the project. I will also neaten up parts of the steering wheel assembly later. So this update won’t be very exciting. This is because I may end up trying to source a new steering unit unless what I come up with initially works well.
Following on from part 1, the initial teardown http://www.tehkella.net/retro/?p=853. Now this Chase HQ cab needs some body repairs straight up. At the same time before starting the internal rebuild, I will also cosmetically fix up most of the outside too. As this upright is mostly chipboard, it is not particularly strong in parts, which shows as the is damage around the lower rear plate, where at some stage parts have collapsed around the cabinet base and wheels. To tackle this I am actually going to work on the cabinet side on to start with.
Recently I scored a great TI99/4A Home Computer plus games from eBay. There are some really good games on this 8bit micro, and luckily most can be picked up relatively cheaply.
The item was pick up only, and in another state. Luckily I had a mate visiting that same area at the time, and he was able to pick it up for me and bring it back in his luggage. How is that for service!
The only bad thing in my opinion about the TI99 is the terrible joysticks! So after a clean up of the unit, the first task was to make a joystick adapter allowing the use of standard sticks, such as the Atari 2600 controllers.
Same mate who had the Warriors of Fate PCB also got a Sega Shinobi PCB in a cab he got hold of. Again these boards also have a suicide battery which maintains an encryption table. These boards are very easy to modify to bring them back to life after the battery dies.
A mate of mine got hold of a Warriors of Fate CPS1 (actually 1.5 due to Q sound) PCB. Not knowing much about them apart from the fact that it was a Capcom board he threw some $$$ at it not knowing that this board contains suicide batteries. These are batteries that keep some PCBs alive by maintaining power a decryption table. This is required to decrypt encrypted program ROMs. Once the battery can no longer provide power to maintain the table, the code on the ROMs can no longer decrypted, and the game will no longer work. There are a number of Capcom and Sega boards in particular that work like this. Lucky for my mate this issue can be fixed using decrypted ROMs, and I have the tools to do it. Note the following details are specific to Warriors of Fate.
My next project will be a restore of a Taito Chase HQ cabinet. I have to say that as awesome as Chase HQ is, the quality of the build of this particular cabinet is really bad. Terrible chipboard, really not made to last. So I really do have my work cut out on this one. A quick check of output voltages on this before the teardown showed 12V on one of the 5V lines, enough to do serious damage to a PCB if plugged in. First thing to do is a complete teardown before moving on to bodywork repair, rewiring, and sprucing up the cabinet. Luckily Chase HQ is such an awesome game. Any less, it would only be worth parting out :S First up the purpose of this post is to retain pictures for reference when I do the rebuild. Might be useful to any other owners in a similar situation.
A while ago I picked up an Atari Basketball arcade machine. This is a black and white game made in 1979. I really like this one as it has trackball controls, so it is a bit unusual. I also really like the style of the machine, with a very 70s feel.
This machine is actually in quite good condition, and it is working. I really want to just neaten this up and make it look “nice”.
As per my latest post I have a nice cleaned up ZK Spectrum 48k. Now the most important part, playing some games! Now I don’t have a tope deck to load games, nor do I have a joystick interface. Here is what I did to fix that.
Below: the end product!
