Well, that got interesting. Here's my 178:
Both eproms are 2716, and I checked the documentation I have but that also shows a RAM chip. If I pull both chips it does what you see: 15 times 'selftest' and then the 'prw-on-err restart'. While reading U45 was no problem, U44 gave me mostly 00's until I increased VPP to 5.5V. Now I get consistent results so I hope the file is correct.
I thought of checking the bin file by burning it into another 2716 but all I could find are 25V VPP ones and my minipro only goes up to 21V.
Anyway, see attachments and let us know.
