Although I’m in Sweden this week and the next, I haven’t forgotten about my pinball machine…
I’ve been franticly searching the Internet looking for those elusive parts that I so dearly need to get the machine back to pristine condition and I think I’ve done it.
From the Multigame site (see the links section) I’ve ordered a rubber set, a new pinball, a doorlock and some more small parts, together with some cleaning materials.
David, from www.zaccaria-pinball.com has sold me a spare “H” target and a replica door sticker and they are on the way.
And then the two memory chips… The 6514J-0 was relatively easy to find. A search on ebay found three vendors in the US, so I ordered one and it’s on the way. The 2114L was an alltogether different story. No hits on ebay or anywhere else.
It was even hard to find the correct datasheets for this memory chip, but after going through dozens of datasheets, I finally found the correct one. I’ve put it up here in the datasheets section on the right, so you don’t have to go through that experience yourself.
I found out that Texas Instruments made the same memory at different speeds, after looking up those datasheets and checking the TI speeds with the ones from Intersil, I started looking for a TMS2114L-45NL. Again, no luck 🙁
Then I noticed that the top of the Texas Instruments datasheets state “Previously Called TMS40L45”, so I searched for a TMS40L45-45NL on ebay and BINGO, there’s one on the way 🙂
According to the datasheets it should work, but I guess you never know until you put it in the CPU board and run the test.
Since I spend a lot of time looking for datasheets, I’ve decided to put them up here for anyone else that might be restoring a similar machine…
So why this blog? Because I’m restoring a pinball machine? Duh…
I was walking down my street about a month ago and noticed a sign on a window saying “everything for sale” and a mobile phone number. I looked in and saw this:
So I wrote down the mobile number and called the next day. Yes, it is still for sale; yes, I can come have a look; yes, you can take it off my hands for 75€…
Two days later it was delivered to my garage and now I’m restoring it.
