Hi Barry Unable to assist on specifics but I can tell you that some 74 100is machines were built. The majority residing in China Imported in by Wong King Kong Ltd ( Johnson lee Tel 00852 2357 8888 ) Most are at either Flextronics or Roslare.
You might also like to try in the UK Apollo Fire Detectors ( tel 01705 492412 Matthew Whicher ) or Peter Wain Wright at Coutant Lambda Tel 01271 863781.
In the USA your best bet would be to speak with Mr Jeff Stong who has Just left Quad Systems for ACI. He was the Printer and Oven Product Manager for Quad and SMTech was once part of the Quad Group. He should beable to give you chapter and verse on them ( Tel (610) 362 1200 x 224 )( email email@example.com ).
There is no need to worry about the supply of parts for them either. All parts can be obtained from Reprint Services in the UK ( 01305 849254 ) They are all ex SMTech employees and can refurbish even convert the old 100 series printers. ( Check out their Compact 29 entry level and new R29-V 29" shuttle machines. Real eye openers ! The way SMTech would have gone had they not been closed down.
