256k TC ENGINEERING CHANGE NOTES
ENC TC04-151287
SYSTEM ROM CHANGES: The 256k TC BOOT ROM Ver 1.15 replaced with Ver 1.20.
PROBLEMS: with Ver 1.15 are
1. With Teac drives, the drive motors will not stop running.
2. If the R.T.C is removed, the ye;;ow lines will display as garbage on
the screen.
CHANGES: in Ver 1.20
1. All drive motors (Teac and Chinnon) stop running after reading/writing.
2. If no R.T.C is fitted then the option does not appear on the screen.
3. Options removed from the self test.
4. Networking removed, F2 now used to select monitor.
NOTE: ALL 256TC fitted with TEAC drives MUST have Ver 1.20 Boot Rom fitted.
