Help! ID this Zenith computer

Upon the date 11:00 PM 9/24/99 -0700, Zane H. Healy said something like: It's actually a version of the good ol' Z100 dual processor all-in-one computer. The Z100 was introduced just a hair before the ubiquitous PeeCee model 5150 was introduced in '82. Had a broad following especially since the US military bought thousands of them over several years. Came with M$DOS and CP/M-85 (processors were 8088 and 8085). Expansion bus was S100 which was a great feature IMO. As usual with Heath, virtually all tech info was available including ROM listings therefore a lot of third-party suppliers sold additions and enhancements. I've still got a couple of ZF-110 models here which were the lo-profile units without built-in display. The PeeCee freight train got rolling along at great speed thus running the Z100 machines off the tracks into oblivion :( Much too bad because the Z100 family had fundamentally better capability than a stock PeeCee: was 'open' by virtue of all docs available and S100 expansion and had begun initially to have a broad following because of the third-party applications, hardware, government purchase contracts and finally, follow-on purchases by previous H89/Z90 owners who could run much of their software on the Z100 under CP/M-85. Oh well. Regards, Chris -- -- Christian Fandt, Electronic/Electrical Historian Jamestown, NY USA cfandt(a)netsync.net Member of Antique Wireless Association URL: http://www.antiquewireless.org/
