I inherited a PTC-64 Print Buffer, sans documentation and power supply and
haven't the foggiest whether it functions or not.
Has anyone owned/abused one of these who can tell me the power supply voltage
and if there are any other interesting facts?
Interestingly enough it has a Z-80 and some other fun things on board--
a schematic would be fun.
any help would be greatly appreciated.

They have a computer record of what parts are available for most anything they have built recently. Goodluck, Gary

I have a Xerox(tm) of the original docs (A Mod 12 I set up for a company years ago needed a buffer, and I had access to the Xerox(tm) machine, so...) If you want me to mail them to you (about 60 pages I think), let me know. If you just want a few specs, send specific questions. As for the power supply, I don't remember, but I'll look it up tonight when I get home. All I remember about it is that you've got a Z-80 with about 64K RAM, and I think you can download programs to it using some silly protocol. That way you can run an Intellegent print buffer (ie, you send it the formatting program, followed by the data for several printouts, and it does the formatting and printing) ______________________________________________________________________ | Dean Reece Member Technical Staff |"The flames are all long gone | | The Santa Cruz Operation 408/458-1422 | but the pain lingers on" | |___________deanr@sco.com_______________|___________________Pink_Floyd_|
