I have run my Trak Systems 8900-1 for about 15 years as an excellent GPSDO system. It is no longer redundant as one of the two plug-in power supplies has a failure and one of the 10 MHz oscillators shows a fault. I have the technical manual dated 1995, an appendix of similar size, plus a field-service bulletin.
If anyone is interested in this as a "parts unit", or wants to run it in non-redundant mode I have removed it from the rack. It is standard 19-inch rack width, a bit under 11 inch high and 12 inches deep.
The unit is offered "as is". If interested make an offer plus shipping which could be in excess of $100. If local pickup, of course no charge for shipping.
