The Philips CDI 310 is a transportable Compact Disc Interactive (CD-i) player with a built-in 3.5-inch floppy disk drive and no screen. ICDIA describes it as intended for professional applications that need frequently changed data, and notes that like the Philips CDI 350 and Philips CDI 360 it needs the 22ER9142 docking station to take the Digital Video cartridge.[5] Philips's product introduction sheet, as quoted by retrostuff, presented it as the "Transportable CD-i System with floppy disk drive", combining a CD-i player, floppy drive and pointing device for training, presentations and point-of-information or point-of-sale use, with the floppy drive for storage and updates. retrostuff believes it probably never reached the market in significant numbers; only a handful of units have surfaced.[4] No service manual for the 310 has been found.[4]
Hardware
[edit | edit source]ICDIA's comparison table lists the 310/00 with the first-generation player shell, RC5 and RC6 infrared, 8 KB of NVRAM, an RGB video input, and Marantz as the maker.[1] retrostuff classes it with the 350 and 360 as a "Mini MMC-based" player, with a CXA1145M video encoder, 8 KB of NVRAM only and a CDM 9/44 mechanism.[6] The regular 310 production units carry the label "Philips Portable CD Interactive / Floppy Disc Player CDI 310 Multipurpose System".[4]
The main board is the CDI 350's PM06. retrostuff compared his board with a photograph of a production 310's board and found that on the production board the parts for the LCD panel's +5L and −8L supplies, the screen connector circuits, the display on/off control and the speaker amplifier were never fitted.[2] The floppy drive is run by a separate controller board, PD06, which carries:[4]
| Part | Function |
|---|---|
| National Semiconductor DP8473V (QL01) | Floppy disk controller |
| Sanyo LC3564QM-10 (QL02) | SRAM, 8,192 × 8 bits |
| TI PAL 16R4 labelled 7117 (QL11) | Programmable logic |
| 24 MHz crystal (XL01) | Controller clock |
| JL01 to JL04 | Flat cables to the main board's extension socket J606 |
| JL05 | Feed-through extension socket for the 22ER9142 Digital Video dock |
| JL06 | Flat cable to main board connector J402, the screen connector on the 350 |
| JL07 | 26-pin flat cable to the floppy drive |
retrostuff notes that the same mix of parts, including the PAL marked 7117, appears on the floppy controller boards of Philips's larger Maxi MMC and Mini MMC players such as the CDI 605T.[4] The drive is a slim Mitsumi F359F2.[4]
The EMC test unit
[edit | edit source]retrostuff has documented a CDI 310 that was evidently a pre-production unit built for electromagnetic compatibility (EMC) testing, with serial number 000005. It was assembled from a CDI 350 chassis with a purpose-made closed top, copper tape throughout, hand-assembled controller board, and many reworked or removed parts on the main board; its system ROM was a pre-release version 1.1 on a Toshiba TC544200F-150 one-time-programmable chip with a handwritten date of 93-7-10.[4][2] Its observations are the main published source for the 310's internals, so check which details apply to a production unit before relying on them.
Known faults
[edit | edit source]retrostuff calls the Mini MMC-based players' leaking SMD electrolytics a known weakness of the generation, and both the main board and the floppy controller board of his 310 had leaking capacitors. The unit showed bad video output, and neither the floppy drive nor the serial connection worked.[4] See the Philips CDI 310 General Maintenance page and the Philips CDI 310 Capacitor Replacement Guide; for the shared main board, the Philips CDI 350 Troubleshooting Guide applies.
