Re: Can't boot AmigaOS

[Ben Bogart - FMPM/F1999 <bbogart%acs.ryerson.ca@localhost>]

I know that my ram problem is caused by a bad connection between the ZIPs 
and the sockets, but I've found that the cause is loose sockets. I've not 
found any good solution as of yet. (I've just been unable to use the thing) 
I've thought about glueing, soldering and buying new hardware to bypass 
the problem but I have little money and am not convinced that gluing will 
work. (soldering just too dangerous.)

Thanks
Ben
