Summary:
I have one, with another on the way. I use LDOS to run all of my old
TRS-80 programs, and CP/M 3.0. While I have written nothing that accesses
the CRT controller or the display memory (other than reworking the CPM 2.2
font for reverse video some time ago), I have the 80 column mods for LDOS
and VisiCalc, and some programs that simulate bit mapped graphics(!) on the
display. The Maximul disks are a must have.
In the hardware area, I build a ram-drive (256k) from a kit originally
intended for big-board systems. I have software to use it in LDOS, both
high and low memory versions, and in combination with the internal 64k
ram drive. I also have modified CP/M+ to use it -- it is a replacement for
the hard disk driver module -- this makes it possible to use Lobo's
configuration program. The second LOBO will have an IOMEGA 10 Mbyte drive,
for which I have to write a driver.
I also made numerous mods to the character output routines for CPM 3.0 to
get performance doubled (they are very slow). Other than that, their
implementation of the BIOS is the best I have seen. A fellow I know who
has a product (KAMAS) that runs on CP/M+ says that it is the only complete
implementation among Lobo, Osborne (Executive) and Morrow as far as handling
the serial device redirection and baud rate selection.
I know several other LOBO owners in the area, but I don't know if any others
have net access.
