This is a powerline only model, no batteries inside. The connectors from left to right are serial, video (RGB) and parallel for printer. The hard disk (a Conner 46MB model) was nearly defunct, so I replaced it with a Conner 120 MB; the BIOS does not recognized this, so I downsized to the nearest IDE type of 33. The settings of 4 jumpers on the motherboard were wrong, so that Laplink over COM1 did not work initially.
