Today it just struck me that the
Batong BT-986 II has the same termination number as the
Pyramid PEC-586 from Dongda Electronics. Digging further reminded me that that there exists a
Batong BT-686 which has not been confirmed so far to be Famicom compatible. The final word is that it actually is, the Famicom slot is hidden in the right slot, at the very front of this space so it's usually not visible in photos. This region also houses two small cartridges. The first attached photo shows the compartment housing the included software cartridges. These are strikingly similar to the ones found in the
Dong Da Pyramid PEC-9388 (
Sonic REC-9388 in Russia). The second attachement presents two Chinese
PEC-9388 cartridges. The shape matches for the most part but the cover area seems smaller, it may or may not have been moulded using a different die. But the ID matches and the asymmetrical design is quite unique on its own to suggest there may have been something going on with these two companies.
This video shows two Batong-Sunsonic consoles. The first, whose exact model cannot be identified, has the two extra slots and a floppy disk drive. The second, identical to the first on a first glance, lacks the drive and the extra slots. The plastic shell used is the same so they covered it with some soft plastic bearing the brand and model number - Sunsonic 686.
I couldn't find many others *86 consoles but the
JT-486 exists as well (the Chinese
PEC-586 is also shown in this tweet).
(Chinese names of both companies: Batong - 八通, Dongda - 深圳东达电器有限公司研制)
