Documentation Wanted
From MAMEDEV Wiki
| Chip name | Maker/Brand | System / driver | Priority | Notes | |
|---|---|---|---|---|---|
| DP8534-V | National Semiconductor | Second-generation 68040 Macs (Quadra and Centris 610/650/800) | Low | I was able to reverse-engineer enough of this chip from a Linux driver to create a usable emulation (thanks smf!) but some details are still unclear. | |
| F8680 PC/CHIP | Chips and Technologies | Cablenet 2039 Controller | Low | Enhanced 8086 CPU with PC-like on-chip peripherals and one or two custom instructions. Some documentation is online, but Programmer's Reference Manual (UG75) is missing. | |
| HPC family (e.g. HPC46003) | National Semiconductor | Various ISA/MCA storage controllers, AGE crane games | Low | The most detailed architectural reference, the HPC16083/HPC16043/HPC16003 User's Manual (424410897-001A), is unavailable, though datasheets and application notes are easy to find. The HPC46400E User's Manual (420420213-001), though for an uncommon later model, may also be of interest here. | |
| M16 series (M31000, M31002, M31010, M31011) | Mitsubishi | Korg Trinity | Low | 32-bit CISC architecture related to M32 (but not M32R, M16C or M32C). https://github.com/linuxha/asl/ supports its assembly language. | |
| MN1600 series (MN1610, MN1611, MN1613, MN1617) | Panasonic | Fujitsu/Panafacom/Matsushita FACOM 9450, C-15/C-x80 and Operate xxx series | Low | http://www.st.rim.or.jp/~nkomatsu/panafacom/MN1610.html has a lot of info but isn't complete, especially for the MN1617. | |
| MN1860 series (e.g. MN1860003) | Panasonic | CD-ROM drives | Low | Upgrade of MN1880. Selection guide summarizes features of a few models. Instruction set mostly deduced from reverse engineering. | |
| MN1880 series (e.g. MN18801A, MN1880023, MN1884820) | Panasonic | Novation synthesizers, Yamaha PSR-500, various CD-ROM drives | Low | Selection guide summarizes features of a few models. Instruction set mostly deduced from MN1872423 (MN1870 series) documentation and reverse engineering, but most internal registers remain mysteries. | |
| PPC1, PPC2 | Paradise Systems (later Western Digital) | Sun 3/80, Schneider Tower AT 220, various Paradise/WD "pre-EGA" ISA cards | Low | These probably work similar to other PC parallel port controllers, but datasheets are not available. | |
| SPC900/SPC970 series | Sony | MechaCon in older PlayStation 2 models | Low | Very little is known about this 16-bit MCU architecture beyond some not very informative datasheets. |
