Tandy TRS-80 - PC1

• 1424 bytes of program memory
• 26 data memories (more can be used at the expense of program memory)
• 24 digit alphanumeric LCD
• Programmable in Basic
• Optional interface for ticket printer and tape

A rebadged Sharp PC1211. The data memories could be referred to as "A" to "Z", or as "A(1)" to "A(26)". This can lead to some confusion. A program like:

10 FOR I=1 TO 10
20 A(I)=1
30 NEXT I

Will loop forever, as "A(9)" is the same as "I". So, "I" gets reset to 1 whenever the it get to 9..
