Yes, I do circuit board repairs for all Zaccaria games.
Basic CPU board repairs include removing the NiCd battery, cleaning up the leaked battery alkaline, neutralizing the board to prevent further damage, and replacing failed or damaged components. A 5.5V 1F memory backup capacitor will be installed in place of the battery. This does not include replacing the Signetics 2650A processor IC.
Driver board repairs include replacing failed components and minor board rework to repair damage from previous failures or repairs.
Power Supply board repairs include replacing the input connector header (if needed), replacing the fuse clips and fuses (if needed), and replacing other components if needed.
Sound Board repairs include replacing any simple components needed. They do not include replacing the amplifier IC.
Display repairs include the components and will vary depending on which component(s) need to be replaced. Glass display tubes may not be available, and are not included. Contact me for details and availability.
All boards will be tested and verified working. The work performed and new parts installed are warranteed for 60 days. Used parts (display glass tubes) cannot be warranteed.

I ask that you send the entire board set (power, driver, cpu, sound) in for repair, and to include the interconnecting ribbon cables. I do not charge for any board that I don't work on, and this allows me to test them as a full set and ensure that they are all working. This helps ensure that a problem on one board does not affect the other board(s) when they are reinstalled in the game.
For the boards marked Contact, please contact me before sending one of these in for repair. It is likely that I can repair it, but either have not done enough of them to establish a fair price, or need to discuss the options and possibilities with you before you send it.
Effective 1 November 2009, an overseas shipping cost will be added to cover the increased cost of postage outside the United States.
This board may be repairable, but I have no information on them at this time. If you have a working one, please contact me. If you need one repaired, contact me and maybe we can work something out.
