HP86 problem

[Martin Hepperle]

- these error messages are described in the user manuals (look at the appendices).

- the bug lists describe bugs found in hardware and firmware and whether they had been fixed in later revisions or whether workarounds exist. These lists are not relevant for your problem.

- if you have an external storage medium or the HPDRIVE emulator you could use one of the emulators to write a small AUTOST program, store it on the disk and then boot the system from this disk to check whether the system core (ROMs, RAMs, CPU) works (an AUTOST program is executed when the system finds it on a disk at boot time).
If this is the case maybe the keyboard is not properly connected or there is a problem with the keyboard controller.
