Panasonic luggable

While looking for another part (actually a replacement door for a Tandon 5.25" drive) in the depths of my workshop, I came across a machine I'd half-forgotten owening, and wondered if anyone recognises it. It's made by Panasonic, and is a luggable. The carrying handle is one one side (not the back, as is usual for such machines). The front of the machine comes off, and is an XT-layout keyboard (alas F9 and F10 are missing on my unit, but I'll bet that's what the missing keys should be). The front of the main unit has a 9" monochrome CRT, and to the right of it 2 vertical half-height 5.25" drive bays. On my machine the left one contains a floppy drive, the right one a Seagate hard drive. To the left of the CRT is a pull-out stretchy cable ending in a mini-DIN plug that fits the hack of the keyboard On the back are the normal mains connnector, switch and fuse. A DE9 connector marked RGB (CGA pinout?) a 36 pin microribbon printer port and a DB25 serial port. On top of the unit is a thermal printer. It comes apart by removing numerous screws. In the bottom of the machine, accessible from under the chassis is a large PCB. It contains an 8088 with a 40 pin DIL socket alongside it (8087?), 256K DRAM, 8250 serial chip, 8255 parallel chip, 6845 CRT controller, a PQFP surface=mount device alongside it (video circuitry), 8257 DMA chip, etc. Basically, what you'd expect to find on a PC/XT motherboard. Theere are 2 62 pin expansion slots, one of which contains the hard disk controller (looks to be a generic PC/XT part), the other contains a PCB with 512K RAM (I would guess only 640K of the totla memory is useable) and a real time clock chip. The printer has its own cotnrol electronics based round a 8050 microcontroller. The keyboard contians an 8048. Does anyone recognise this machine? -tony
