Good news sean, if that's a TMS1100 it would make emulation doable I guess
Curious to see if Baseball 1 will use the same chip.
Not really related to this, but could you please confirm what's the CRC32 for your latest Pinball dump for Microvision? I just realized the rom bundled with Paul Robson's emulator doesn't match the one in the MESS software list.
I know you corrected an error you found at a later point, but I'm not sure which one is the correct version anymore.
