Its considerably better than the alternatives :-
- EPROM removal and dump on a programmer: EPROMs could be damaged by heat, lose/bend legs and then you need to solder them back in or socket them later. In both cases the cart would no longer be classed the same as the original find, in my mind.
- Attach a flying clip and dump on a programmer: This runs the risk of over-driving the output enables and chip selects of the EPROM, thus causing damage to the supporting logic chips.
Atarimax have designed (and produced) SD based multi-carts for the Colecovision and the 5200 as well as providing reprogrammable carts e.g Maxflash to the A8 community. Based on those products alone I'm quite sure they have a good electronics knowledge and their cart dumper isn't going to damage your prototype. Besides that, people have already used the Atarimax Inty cart dumper without any reported problems.
I'm in complete agreement. Put yourself in my shoes for a minute. I've just found a rare and interesting item and now I would need to do destructive modification to it (potentially) to ensure it is read.
Also thinking about it ... I would think that any modification to the original (even if an improvement like socketing the roms) should from a collectibility standpoint lower its value.
I would think an attempt to externally read the ROM is better than desoldering chips from a 30+ year old circuit board. If this Atarimax thing is able to dump INTV ROMS it shouldn't matter much that the ROM is an EPROM. I mean after all the INTV doesn't seem to notice any difference. I'll try it out on my INTV II I have as well although I'm sure it will play fine.
Also I started looking into EPROM use for classic video game systems and I learned something new. All Adventrure vision carts are actually EPROMS as well as some Neo GEO AES (The arcade compatible boards) use EPROMS for games from the factory. Many people claim there has been no reports of failures of these games as long as they are sheilded from UV.
