My company (Hugur of Iceland) is doing the following to Tandy 102's: We remove the keyboard, and replace it with a membrane keyboard, we install a main transformer and recharger so the machine charges Ni-Cads when main power is available and runs off them during power failures. Also: We remove the OS-ROM and put a socket there, we then install EPROMs that contain programs written in C, compiled using a C compiler that produces ROMable code for the Tandy102. The compiler is made by King Computing of California. We also use the barcode interface. We reverse-engineered a barcode program included with the barcode wand from radio shack and wrote a better one that is pollable and doesn't hang up the machine until something has been scanned. What is the result of all this? A time clock that collects trans- actions at the factory entrance and transmits them to a PC over a serial cable or modem once a day. The cassette tape motor relay we use as a switch for ringing the coffee-hour bell at presettable times. We've mutilated 400-500 Tandys so far! PS: When we replace the OS-ROM we replace the character set at the same time since Icelandic has 20 special characters.
