Rick, I doubt you will be able to get into this arena for less than about $200. That would need to include a programmer and a computer with WinXP. The more older equipment you have, or want to have, the more you will be motivated to develop this capability.
If you are old, like me, and you got computers many decades ago, like me, and you keep things, like the original packaging, like me, you might have the computers that would work. Then, you might be able to get a programmer for about $100+/- that would need a Parallel Port and be able to do the programming. However, happy to help any way I can. Just let me know when you ship. My address is @ WB4BPP. If you are not a HAM, let me know and I'll send you the particulars via PM. I downloaded the 7081 EPROM files from the Solartron group provided by David Partridge and will use those to compare yours to and program/reprogram your chips to. I don't know if the battery is a problem with boot up or not but I suspect David might.

I think to spend more than that on tools that may not be used again isn't smart...although I have broken that guideline many times! I think using a USB to RS-232 or USB to parallel adapter makes for a good rabbit hole too. I successfully cancelled the programmer I already ordered as it didn't have high enough programming voltage even though it said it supported the TMS2564-JL chips. So, Joe, I'd like to take you up on your generous offer to read the old ones and program the new ROMs. I was able to confirm this morning that the ROMs I ordered are the correct versions. They should be here to my house by Thurs this week. I'll reach back out to you once they've arrive. I've also ordered a new battery for the B1 real time clock. It is dead. That should be here tomorrow. Will be interesting if the battery is part of the boot up problem.
