How to repair an ENIAC???
I've just bought an ENIAC on the local flea-market but this
computer is really full of "bugs". How can I fix this monster and do you think it can compete with my Commodore 64??? |

I assume eunet.esprit is his scorecard group (was: How to repair anENIAC?)
eunet.esprit removed from Groups line.
If you respond to this troll, I suggest you do the same. http://groups.google.com/group/sci.e...0.newsgrou ps Carl Dau wrote: I've just bought an ENIAC on the local flea-market but this computer is really full of "bugs".

None of the above; baseless miniature tubes like those didn't show up until quite a while after the ENIAC was developed. Most likely it would be a 6SN7, though other octal-based tubes of similar vintage were used too. Isaac |
