[vcf-midatlantic] TRS-80 PC-1 & Printer

This is a normal problem for most PC-1.  You will need a new LCD.  The problem is the seal drying out around the LCD starts leaking and then it bleeds from the outside in.  

If you find a new LCD, then simply seal the edge of the screen with aquarium silicone so it never dries out.   I did this for my PC-1 when I got it so it will be good for another 35 years or more.  

As for the battery, don't bother trying to charge it.  It's bad at that age.  Just desolder the old one go to batteries plus and have them make you a new battery pack with welded tabs.  Be careful with the battery pack once you install it some lines are always live and if you short them like the ribbon cable to the printer mechanism they will melt.  Ask me how I know....  

If you get it all sorted I have every cassette radio shack made and can make you copies.  The problem with the PC-1 is that it's very particular on which cassette recorders work and you can't use an iPod or a MacBook audio.    Not enough gain.  I guess you could attach a preamp. 

I went out and bought a new radio shack shoebox tape recorder on sale.  Apparently they still have them.   My Panasonic Rq-2102 that I used with my apple and sol-20 setups doesn't work with the PC-1, but does work with my PC-2. 

Good luck,
