I found a Z80 based machine. Externally looked like an XT clone, with a wooden (!) case. Inside, I found a Z80 based MB (all chips are socketed) and a WD-1001 card. Yes, there's a floppy drive, and HD and a unusual tape streamer. On the rear, six DB15 female ports and a 50pin connector. The label says EMI Computer Systems Italy, Model 80/30 (BTW it's different from the IMSAI 80/30). I read the 4k (2732) EPROM, which contains a small monitor, allowing to boot from various sources. Nothing more. I assumed the six ports to be serial ports. I connected a terminal (virtual, putty) through a null modem cable (the one I used for all console operation) and powered the machine up. Floppy and HD led were lit, but saw no activity on the ports. I tried various speeds (1200, 2400, 4800, 9600). The reset switch makes the HD led go off and on, so something still works... 1 I haven't any info about this old beast, so can't tell if it's broken or I'm wrong somewhere. Must try without the null modem cable... Did you ever see that brand (EMI Computer Systems)? Thanks!
