Hi!
I found and replaced a faulty 4116 ram chip: I used an oscilloscope to
monitor pin14 (DOUT), and the faulty chip showed no activity at all...
Now's the trouble: where can I found some disk images (double density)?
My O1 has the DD upgrade.
I found only a DD CPMSYS disk image, but it hangs after having loaded
the HELP.
The floppies which came with the O1 are almost unreadable.
Only one could be read (by now).
This disk boots the O1 in a minimal CP/M: setup works, xref works, but
mbasic and cbas2 hang.
I searched the web, but links have been outdated...
Thanks!
