Well the last few days have slow again Holidays I guess. Picked up a Alpha Micro model AM1051-12 AM-410 SN 2517. It's a heavy unit and I have not powered it up yet. Anyone have any info on it. A TRS-80 RS232 Interface selector not tested. A AST-2000 Subsystem model MAC-200, anyone know what this unit is ? Four Mac IIci cases for parts only the guy let me have them for free. A Ultimate model 25 by ADDS with one aux port and EIA current loop port. That's it so far for the week. As far as prices no unit cost over $6.
