Was there more than on original Pac Board configuration

[mammoth]

I just noticed new listings on eBay with what they claim are original pac or Ms. Pac boards. there does not to be a Z80 location on the boards by the side edge and they have one less ROM - picture is a little hard to make out but in all cases you can make out the MIDWAY MFG CO. lettering on the board. Was there an an actual original midway board with this configuration.(items are #'s 6185413831, 6185404582, and 6185397844) all are new listings but by different sellers. I have 6 pac boards and have never seen this set up - any ideas?

Being a pac-man collector, and owning about 20 of these boards at one time or another, and repairing them, let me chime in:

6185413831 and 6185404582 are using the same pic (same, not different seller)

If these are pics of the boards then the seller is lying. There are missing chips on the main program row (look just under the Z80 SBC daughter card towards the top middle of the pic).  Also there is no daughtercard, and there are no "single" eprom hacks to the main row.  So what the deal is, is this is probably a Pac-man converted to Ms.Pac-man, and the daughter board and ribbon cable and at least one of the eproms were removed prior to sale.  He called it a Ms.Pac because the graphics roms in the next row probably have MsPac labels on them.   Someone will be very disappointed in this as even if the board works, it will take about $50 more in parts to get it to work as MsPac in "original" form.

The Z80 socket is hidden by the Z80 SBC daughter card... Who knows if they even have CPU's on them given he's reusing the same pic AND they're missing parts... AND he's a brand new ebay seller.  If you have the RARE pac boards with a single chip SBC that rests alongside the Z80 chip then you're lucky. There are VERY few of those out there.  They ran out of the single chip SBC and VRAM controllers and had to go with multi-component daughter cards that hide the components under them.  In the 20 boards I've had, only 1 had a single chip SBC (original -- not one of the newer remakes) and none had a single chip VRAM.


re: 6185397844 -- This is a different seller. It appears that the sound amp capacitor was changed from an axial capacitor to a radial one (one with one wire out both ends to one with 2 wires out one end). So it's been worked on at least once before.  There may have been another smaller one replaced similarily on the program rom row (lower center). Otherwise this board looks "complete" though of course I can't see if the 4th eprom or z80 is actually under the SBC
