What is it? This is a pin-for-pin compatible nearly exact replacement for the LCD module in the Radio Shack TRS-80 PC-3 or Sharp PC-1250/-1251/-1255 pocket computer released in 1983. Why did you ma...Read More…
Many PC-3 and PC-125x pocket computers suffer from LCD degradation to the point where they are no longer useful. Apparently the seal around the LCD was of poor quality, and over the years moisture gets in and ruins the liquid crystal. The result is a display ranging from a few splotches to complete failure.
I decided that it was important to bring all these dead PC-3 and PC-125x computers back to life by reverse-engineering the LCD and remanufacturing them.
These LCDs were custom manufactured by Sharp for the PC-125x. Radio Shack had a rebranding agreement with Sharp, and named the computer the TRS-80 PC-3. Replacement LCDs were never available, and finding a working LCD is problematic, given the systematic failure of the seal.
I tried as much as possible to make the fonts and positions used for the indicators as identical to the original as possible.
I've made a video showing how to replace one of these LCDs. There are a few crucial things you have to be aware of:
Due to the UK’s changes to VAT treatment of overseas goods effective 1 Jan 2021, Tindie, as an Online Marketplace (OMP), is required to collect VAT on sales under £135. Tindie currently does not have a mechanism to do this. Until this happens, sales to the UK must exceed £135 (the equivalent of 10 LCDs). Therefore, I cannot directly sell to buyers at UK addresses unless they purchase 10 LCDs or more.
However, you can use a package forwarding service such as borderlinx.com. They do handle VAT correctly, and come highly recommended. You will likely end up paying more in shipping charges, though. And, there is always the risk that your package will get lost.
The procedure seems to be:
You can see that with two extra stops at warehouses, there’s a higher chance of a package going astray. Nevertheless, I’ve heard that people have good experiences using package forwarders.
