additional information
info 0.33b3 [Zsolt Vasvari]

  • 0.138: Changed visible area to 240x256.
  • 0.136u1: Stephane Humbert fixed cabinet 'Upright' dipswitch in Zoar.
  • 28th February 2009: Guru - I decided to have a look at the Zoar custom CPU that Smitdogg sent a short time ago. Here's a few pics of the process. This was more of an academic exercise than anything else, since the game works fine in MAME. The inside of the plastic housing had segments in it that actually made it *a lot* easier to remove the epoxy as it broke off in quite large pieces. Inside we can clearly see a 6502 CPU and a few logic chips, pretty simple stuff really. At least now we know the devs got it right. But unfortunately now the PCB is not working, so alas, the Zoar is no more. UPDATE: One of the devs put in a request for a schem, and since there may be others who are wondering what the CPU module circuit looks like, here it is... Revision 1.0. Don't try this at home though boys and girls, this thing only has 10 chips and it took 6 hours to draw! OMG!
  • 0.129u4: Guru added PCB layout for Zoar, corrected AY-3-8910 clocks and added missing PROM. Changed clock speed of the 2x AY-3-8910A to 3MHz. Added prom ($40) and 'Cabinet' dipswitch. Fixed rom names.
  • 13th January 2009: Guru - A Zoar PCB for attacking the epoxy block arrived yesterday. Thanks to Smitdogg.
  • 0.129: Aaron Giles removed BAD_DUMD flag from rom zoar15.
  • 16th December 2008: Smitdogg - I got a Zoar PCB a few days ago.
  • 0.128u5: Fixed gfx3/bg_map rom loading.
  • 0.126u3: Changed name of dipswitch 'Cabinet' to 'Control Panel'.
  • 0.126u2: Fabio Priuli added DIP locations to Zoar.
  • 0.34b8: Added proms ($0, 20).
  • 0.33b4: Zsolt Vasvari added accurate colors to Zoar.
  • 0.33b3: Zsolt Vasvari added Zoar(Data East 1982).
