The chips marked with numbers (1) CPU and (2) DRAM memory should be desoldered. 4 | 2. If possible, gently put the capacitor (3). If not, solder a new one lying down. 5 | 3. In place of the CPU (1), solder the precision socket. 6 | 4. In place of the DRAM memory (2), you can solder the sockets, if you want to return to the previous configuration. 7 | 5. Put the mapper module into the CPU socket (1). 8 | 6. The point marked on the mapper PCB as SLTSL is connected with a cable to the place where pin 16 of one of the DRAM chips was. 9 | 10 | All modifications are reversible. It is enough to unsolder the cable, remove the module and insert the CPU and DRAM into the sockets. -------------------------------------------------------------------------------- /docs/panasonic_fs-a1/panasonic_fs-a1_mapper01.jpg: -------------------------------------------------------------------------------- https://raw.githubusercontent.com/konkotgit/MSX-Memory-Mapper/ee29530e48dfa346cf178752b1e42c6c0f41bbe5/docs/panasonic_fs-a1/panasonic_fs-a1_mapper01.jpg -------------------------------------------------------------------------------- /docs/panasonic_fs-a1/panasonic_fs-a1_mapper02.jpg: -------------------------------------------------------------------------------- https://raw.githubusercontent.com/konkotgit/MSX-Memory-Mapper/ee29530e48dfa346cf178752b1e42c6c0f41bbe5/docs/panasonic_fs-a1/panasonic_fs-a1_mapper02.jpg -------------------------------------------------------------------------------- /docs/panasonic_fs-a1/panasonic_fs-a1_mapper03.jpg: -------------------------------------------------------------------------------- https://raw.githubusercontent.com/konkotgit/MSX-Memory-Mapper/ee29530e48dfa346cf178752b1e42c6c0f41bbe5/docs/panasonic_fs-a1/panasonic_fs-a1_mapper03.jpg -------------------------------------------------------------------------------- /docs/panasonic_fs-a1/panasonic_fs-a1_mapper04.jpg: -------------------------------------------------------------------------------- https://raw.githubusercontent.com/konkotgit/MSX-Memory-Mapper/ee29530e48dfa346cf178752b1e42c6c0f41bbe5/docs/panasonic_fs-a1/panasonic_fs-a1_mapper04.jpg -------------------------------------------------------------------------------- /docs/panasonic_fs-a1/panasonic_fs-a1_mapper05.jpg: -------------------------------------------------------------------------------- https://raw.githubusercontent.com/konkotgit/MSX-Memory-Mapper/ee29530e48dfa346cf178752b1e42c6c0f41bbe5/docs/panasonic_fs-a1/panasonic_fs-a1_mapper05.jpg -------------------------------------------------------------------------------- /docs/sony_hb-f1xd/sony_hb-f1xd_mapper01.jpg: -------------------------------------------------------------------------------- https://raw.githubusercontent.com/konkotgit/MSX-Memory-Mapper/ee29530e48dfa346cf178752b1e42c6c0f41bbe5/docs/sony_hb-f1xd/sony_hb-f1xd_mapper01.jpg -------------------------------------------------------------------------------- /ver-B/BOM/ibom.html: -------------------------------------------------------------------------------- 1 | 2 | 3 | 4 |
