I doubt Jerry Pournelle is out there in "UsenetLand", but perhaps there is someone else who can help me. Just recently a friend gave me her Otrona Attache to fix and return. When I told her that the problem was probably the power supply and I couldn't fix it, she told me that I could keep the machine if I could get it to work. Ah ha! This is my problem. For those of you who are not familiar with the machine, Otrona is a company that went under several years ago. However, the Attache, a CPM transportable with dual disk drives and 5 inch monitor, is a darn nice little machine. When I turn on the machine I get nothing. Zilch. It is completely dead. She said her daughter killed it when she went to Europe, and it hasn't worked since. The power supply is built to work with varying voltage standards, however, you have to reverse a card in the back to keep it from blowing. This I doubt she did. I opened up the machine, for all the good it did me. The switch is okay, and there is NO power to the fan (which works fine). With my limited electronics experience I would say the power supply is probably the culprit, no? Now, for the questions... 1. Is anyone aware of a power supply I could buy for it? Unfortunately, Attaches don't use the nice little modular boxed supplies found in todays PCs, but rather an open one that runs across two pc boards. I assume they did this to make it compatible with other standards. 2. Does anyone know if these machines are still serviced? 3. I am aware that the Attache has an input on the back for a DC power supply, namely a battery pack. However, they don't define the configuration for the pins in the manual. Does anyone know this pin configuration? Would it be possible to use another external power supply using this DC input? 4. Am I wasting my time? I hope not. All I have is a crummy little Apple //e with NO good terminal emulation software, and no good Kermit driver. In addition, the Attache sure would be nice in the dorm... 5. Could anyone give me any additional info they might think would be helpful? Thanks in advance... "Out there in the desert I see dreams on every wall. Nothing's ever solved.
