World's first computer on ebay!

A Tatung Einstein??? Since when has a Z80-based machine been the first computer (or even the first home computer). For those across the Pond, I'll post some details of this machine. It came out in the early-mid 1980s, after the BBC Micro. It's basied round a Z80A, clocked at 4MHz. There's 64K of RAM, with a 16K ROM that can replace part of the RAM (if you see what I mean). This ROM contains a reasonable machine code monitor, but not a lot else. The video side is baed round the TMS9927 chip (that's a PAL version of the 9918) with its own 16K of RAM. Sound is an AY-3-8910 chip, the digital I/O ports of which are used to scan the keyboard (a plain matrix of switches). There's a built-in 3" (not 3.5") floppy drive with a WD chip (I think a 1170) to control it. And space for a second drive. There are a reaosnable number of standard interfaces. IIRC, there's a connector for 2 external floppy drives (standard 34 pin, Shugart SA400-like pinout).Aa 60 pin bus connctor called the 'Tatung Pipe' (the name is a pun on 'tube' which is what Acorn called the second processor interface connector on the Beeb, in turn 'Tube' is a pun on 'bus', both being public transport systems in London) is an expansion bus connector carrying the standard Z80 signals. There's a Z80-PIO on the board, one port of which is used as a Centronics printer interface, the other port is used as a user port (2 more conenctors on the machine). There's a 4-channel 8-bit ADC (ADC0844 IIRC), used for the Joystik ports (but which obviously has many other applications). An 8251 provides a serial port, buffered to RS232 levels, and brouhgt on on a 5 pin form C (quincuncial) DIN plug with a sane pinout (unlike the Beeb, on the Einstein, turning the plug round does the null-modem swap). This conenctor carries TxD, RxD, RTS, CTS and Ground, DSR and DTR are available on marked solder pads on the PCB. One odd thing is that the colour monitor connector can be set by internal links to be either RGB or YUV analogue video. There's also an RF modulator to drive a TV The standard OS was called XtalDOS and was very CP/M like (although IIRC, some of the commands were re-named). There were several versions of BASIC for the machine (including a 'BBC Basic') and other languages available on disk. It's not a bad machine, although it's somewhat let down by the video chip (there's no 80 column text mode, for example, although there was an add-on board to do this). But it's not worth what this person is asking IMHO -tony
