Perfectly working Minidisk. Also recording Micro switches cleaned Including 1 md disk. Essentially the same as an MDS-JE500 (circuit board, A/D/A chip, ATRAC chip, main ASIC, user manual, feet, all identical). Some units made in Malaysia. European/Japanese unit (see below) adds A-B erase. TOC cloning not possible (machine ejects disc when power applied). Components: MD mechanism type: MDM-3A/3B, Optical pickup type: KMS-260A/J1N Variants: Information in the service manuals indicate that there are at least two JE510 models, the AEP, UK, and German ``European'' model (with coax input) and the US, Canadian and E ``North American'' model (lacking coax input). The NA model contains the same mainboard, BD board, HP board, optical pick-up and drive mechanism as the JE500. The European model has a different mainboard layout to carry the coaxial input and a few more capacitors in its analog section. The coax input adds a connector, three resistors and one capacitor, but no new ICs. The principal difference is that the NA model has the CXD2650R chip while the European model has the CXD2652AR instead. The latter can control an external DRAM chip, in this case IC124 -- a 4Mbit dram memory buffer, giving a total of 6Mbit DRAM when the internal 2Mbit DRAM of the CXD2652AR is included, this allows the 6 second time machine function on the European and Japanese versions. Incidentally, the CXD2652AR with 4Mbit external DRAM memory is used in the MZ-R30. The CXD2650R and the CXD2652AR chips are both ATRAC 4.0.
