I am looking for a source for a replacement for a Komami 501 IC as found on Gyruss.
I have a (otherwise) working Gyruss boardset that donated its 501 to my Track & Field to fix a graphics glitch. There was a single stuck pin causing the players to have lines running through them.
My google-fu has turned up lots of old links and seeming not accurate information... I found a cross reference of Konami chips claiming this was used on Gyruss, Pooyan and Time Pilot... but not Track and Field...and I know it is on T&F...
I have found references to FPGA projects but its unclear if those are available...
I have found references to a daughterboard used in some cases to replace this IC (PWB 402034) but can't find any specs or schematics on that.
Anyone out there have any ideas?
Thanks for reading!
