Set of homebrew multirom cartridges for the P2000T. These cartridges contain multiple ROM files stored on a single parallel EEPROM chip. The user can select the desired program using a DIP switch. More information on these cartridges can be found on the website.
SLOT1 cartridge that allows the user to select one of 32 banks (assuming a 512kb ROM chip is used). A specific bracket PCB is used to hold the DIP switch which needs to be wired to the PCB. This cartridge also hosts a soft reset switch with a debouncing 74HC123 multivibrator.
There is also a Multirom cartridge using the venerable W27C512 chip, providing 4x16kb of space. In contrast to the 512kb version cartridge, this cartridge does not contain the soft reset as a cost saving measure.
SLOT1 cartridge that allows the user to select one of 32 banks (assuming a 512kb ROM chip is used). Instead of a fixed ROM chip, this cartridge uses a ZIF socket for easy exchange of the ROM chip. The cartridge also contains a soft reset switch.
Simplified version of the SST39SF040 / 512kb cartridge meant for easy soldering. This cartridge assumes that the SMD components are already placed using an assembly service of the PCB manufacturer.
All enclosures have so-called mouse ears which helps in the adhesion of the enclosure to the print plate. This prevents warping.
Recommended print settings for the enclosures:
- 0.4mm nozzle
- 0.15mm layer height
- 10%-20% infill
All cases are labeled using the following notation: ABBR-X-[T/B], where
ABBR corresponds to the cartridge type (see list below), X the revision
of the cartridge and T/B for the top or bottom parts.
