Homelab for MiSTer FPGA
Description
This is a Homelab running on Mister FPGA.
Original MiST core by gyurco.
It was ported to MiSTer by JasonA. HTP support was added by Flandango.
Homelab was a series of Hungarian KIT computers in the 1980s invented by József Lukács and Endre Lukács.
Features
- Homelab-3 and Homelab-4 models supported (model switching is done via the OSD)
- Increased RAM size to 48k from default 16k
- 32 character and 64 character video modes selectable via OSD
- HTP rom loading via OSD
- HTP rom loading via ADC
- Turbo mode option for HTP rom loading
- Character rom loading via OSD
- Selectable monochrome video color via OSD
HTP Support via OSD
Type LOAD "" and press enter. This will put the core into loading mode. Select Load HTP ROM from the OSD. Then select Play from the OSD. The user LED will blink as the HTP is loading, and switch off once loading is complete. The core will usually display OK and a blinking cursor afterwards.
Two options are possible to start the HTP file. The first, is typing RUN and pressing enter. Some HTP ROMs though will not work using this. They require an alternative method. This is using the CALL command.
In the HTP filename, a number is usually written for where to call. If it states CALL in the filename, then RUN will not work.
Example:
CALL $5100 and press enter.
This is an example of one, where is states CALL $5100 in the filename. This is not for all HTP files. You will need to check the number in the filename.
HTP Support via ADC
ADC support has been added to the core for loading wav files of the roms via ADC in. You will need the ADC adapter hardware upgrade for MiSTer if using the Analog IO board. The Digital IO board has an ADC-in jack already soldered onto it. The user LED will blink as the HTP is loading, and switch off once loading is complete.
Character ROM support via OSD
Some HTP roms require unique character roms also, to display the video correctly.
Load the relevant character rom needed for each HTP rom, using the option for this in the OSD.
Turbo Mode for HTP Loading
A turbo mode option can be found in the OSD. This will switch the CPU to 120MHz during HTP loading to reduce the loading time. Once loading is complete, the CPU is slowed back to normal mode. This is an optional feature, and not necessary for HTP loading, if not desired.
