Hi All,

Offering a Centipede PCB in working condition but optically it is not that nice.

Good:
100% working incl. EEPROM and POKEY, one power contact has been repaired (see picture).

Not so nice:
There is some white-yellow-ish covering on the parts side that I wasn't able to remove.
However, it is dry and has no other impact than optically.

The price is good - 50 Eur plus shipping from Germany. - RESERVED

Best regards,
Andreas

Considering to sell my Atari CAT BOX (CAT = Computer Assisted Troubleshooter).

CAT BOX - Whats this? - > see here: http://devkits.handheldmuseum.com/Atari-CatBox/

It can be used to troubleshoot many of the Atari classic 6502 based games: Centipede, Millipede, Asteroids (+ De Luxe), Tempest, Space Duel, Crystal Castles ... by using RAM/ROM tests and signature analysis.

And ... its a piece of history and a fine engineering work.

- Good condition with minimal usage signs - trust me!
- works 100% and includes signature check mod for ROMS (reversible)
- Currently runs on 220VAC with no permanent modifications done, so reversal to 110VAC is easy, all original items are still there.
- All signature cables are also there
- Comes with no manual and no additional POD, so can use for 6502 CPU games only

Price: 600Eur incl. shipping within the EU

Need a spare chassis for a Wells Gardner U5000 medium resolution monitor.
Chassis picture is at : http://www.jomac.net.au/WG-U5000.JPG

Doesn't need to be working, but shouldn't be too much hacked.
Needs shipping to Germany.

Helping friends to get a non-working Midway Submarine back to life - we are not finished yet

We had two repair sessions, one in December last year and one more in April 2013. I want to share some interim results and pictures.

December 2012
John from flippers.com was so kind sending me the ROM dumps, so I burned two EPROMS in preparation. Our repair session was not too effective, I think I have to get used working together with another person.
Boards are in an L-shape like many of the early Midway boards. We were able to get the CPU board tested with my Fluke 9010A and working. The original EPROMS were dead, so luckily we had the new ones . Strapping on the board needed to be changed as the original EPROMS were the TMS2716 kind with three voltages and the new ones good plain 2716 with just 5V. Interesting that the four 6810 RAMs were still ok.
With the I/O board we failed miserably. Someone had worked on the board before, that was clear. So we replaced the missing components and did quick check on the rest. That was the problem: we should have checked more intensively !! When switching the machine on, 3 transistors got extremely hot and we were not able to fix that during the remaining time.

Finally I took the boardset home and worked on my own place, did a minimum power harnes and simulated motors by some power resistors, required inputs simulated by switches etc ... I found out that several mistakes were made by the guy who had tried to repair the I/O board before. I fixed that plus two of our own introduced mistakes and now CPU and I/O are at least working on my bench. The CPU board had an additional issue with the 'noise' generator and need a new CMOS 4006 - 18 bit shift register.

To be continued to test the I/O and sound with the Fluke on my desk...

Looking for a Hantarex Chassis w/neck board for - Polo/2 15khz  to meet a lonely tube 

Chassis' condition is rather unimportant.
