Prevue (ESQ)
Prevue Grid, also known as "blue grid", was the final iteration of the Prevue software, used from 1993-1999. Whereas Prevue List displayed a list of what was currently on on each channel, then what would be on in the future at different times, the Prevue Grid showed what was on each channel now and in the future at the same time.
The Prevue Grid software had 3 different names over the course of its history: Prevue Guide, Prevue Channel, and lastly, for just a few months, TV Guide Channel.
Various Functions
The 9.0.4 system software was indeed very interesting, especially in its functions. It allowed background colors in the ads, and it allowed the font colors to be changed, too. However, in emulated versions, it is not practical to get the ads to be shown... yet.
The 9.0.4 system software also made it easy to change the serial number, as seen with my custom "CJ1996" serial number. To do this, you will need to type the following...
1a. Strike Control C while in the main system menu. You then will be dumped to a command shell. Alternately:
1b. Hold both mouse buttons when first starting the machine, click "Advanced Options", disable
the startup-sequence, click "Use", then click "DF0"
2. Enter in sel (your new serial here) then press enter, and reset the machine.
"Guru Meditation"
This certain edition (9.0.4) of the Prevue Guide might cough up Guru errors due to compatibility. It requires the following minimum specs to operate properly.
Kickstart ROM: "Kickstart v2.04 rev 37.175 (1991)(Commodore)(A500+).rom" (later versions may work, untested as of yet) Chip RAM: 1.0MB Fast RAM: 1.0MB CPU: 68000 Chipset: ECS Mode: NTSC DF0: PREVUE.ADF
However, these specs can differ. The software may function properly on other specs, but this is known to work properly. Mis-configuration can cause a Guru Meditation error, like pictured. This particular Guru is caused by insufficient chip RAM. Faster CPUs are compatible with the software (it has been tested with a 68020, and CPU speed seems to be irrelevant as well, as it has been tested on WinUAE with the CPU speed set to "fastest possible"). Insufficient fast RAM will not cause a Guru, but it will cause the software to throw up an ER011 error and freeze up.
