Zenith Z89[edit]

Hi Garlanger, is the information about the Z-90's graphics capabilities and IEEE488 ports incorrect or did you just forget to add them back in? --QEDquid 10:24, 9 September 2006 (UTC)

It was incorrect, Heath/Zenith never provided any bit-mapped graphics on that machine (although some third-party companies had - maybe the system the original author had, contained one of the third party boards). It only had character graphics and the RS-232 was still the standard port.

You can see this clearly in the '81 catalog at: - "High-resolution video display, using a stardard white CRT, can show up to 2,000 characters. Typewriter-style keyboard has 33 graphics characters for business presentations. RS-232 Serial I/O Ports for printer/telecommunications extendability".

Disk controller and amount of standard memory are the only differences - also it was offered at the same time as the Zenith Z-89, it was just a different configuration not a later model (as asserted in the original article) - it was only later than the Heathkit H-89 due to Zenith buying them after the H-89 was available and the time required to make a Zenith branded computer.
