Here's my math..

Marco's Test ROMs > Other Test Roms

Also want to state, no disrespect meant on the other ROMs. They've been an evolution over the years like everything else.. and people doing the TEST ROMs were inspired by the work done by others before them. It's just that Marco's TEST ROMs have far surpassed capabilities in just about anything Marco has a ROM for. I haven't personally used too many of the other ROMs *yet* -- been a while since I tackled repairing a bunch of MPUs, but there's a local repair guy near me that out-of-nowhere continues to compliment this Sys80 tester. Probably a dozen times now, it's like one of the best things ever in his eyes haha. I always tell him most of the credit goes to the guy that wrote the software He's also used other Marco ROMs and has said everything he's used has been awesome. I definitely think Marco should be proud of all his hard work and that others are finding the TEST ROMs so useful!

Just wanted to say that proceeds from sales of any Marco EPROMs purchased from PINITECH are directly donated to Marco once the EPROM cost is paid for. My way of giving back to him since he's pretty humble and hasn't asked for any $$ from anyone that's wanted the ROMs. Plus, the Sys80 Tester really isn't much without his awesome software
