Tandy Model I Problems

Rich,

Hmmm... let's see if I understand you correctly. You have a TRS-80
Model I with EI and floppy drive and when you turn the system on, the
screen fills with random garbage? I have one sitting here in my office
and that appears to be normal behavior if there is no bootable disk in
drive 0 when the computer is turned on or reset. Try holding down the
BREAK key and hitting reset button to enter ROM BASIC.

As I recall, if the EI is connected then the system checks the BREAK key
and jumps to BASIC if it's pressed, otherwise it reads the first sector
from the disk and executes it. All this happens before video RAM is
initialized so the screen is filled with trash.

Hope this helps,

- Doug
