N > NEC  > APC   


This professional computer from NEC was a very nice system at the time. With its high resolution graphics (640 x 475) and its large disk capacity (1 MB), it sure was impressive in 1982!

Bill Czermak recalls:
I developed the first version of MIPS (Manufacturers Integrated Production System) on one of the first colour APCs sold in Australia. I added a 5 Mb NEC harddisk later. The 8" floppies held 1.2 Mb. I am told my original system is in a museum in the Geelong area.

I added an XT compatibility card to port my software to the the IBM XT and my software worked fine using this card. When I installed it on a customer's genuine IBM, I got a blank screen!!! Which I fixed that day on the customer's premesis. I think the APC was 30% faster than the XT and cheaper with better graphics.

Jeremiah S. Junken reports :
I actually have one of these which still works. By default, it runs CPM/86, there was a UNIX available, and MS-DOS available. Mine had an external 10MB HDD. The software included "benchmark" word processor, VisiCalc and dBase II.

The major things worth nothing about this otherwise unremarkable machine were it's relative speed, the fact that the lights would dim slightly when it was turned on, and that, in the year 2002, it still works. :-)

Gary McCray adds:
I actually still have a working one of these also. Actually, it was pretty remarakable when it came out for its high resolution graphics capability using a (at the time) powerful NEC 7220 Graphics controller chip which formed the base strategy for virtually every other graphics controller since.

Unfortunately very little software was available that took advantage of its graphics capability. Also it was featured in one of the stupidist full page ads ever produced and ran for months with a giant hand covering it up and the admonition "The Computer The Competition Doesnt Want You to See" and a suggestion to write away for information on it (see 'Adverts' section). If that wasn't stupid enough, you couldn't actually get any information on it from either writing or calling.

It is remarkably well made and was extremely powerful and reliable in the time it was built (weighs over 80 lb). But a combination of truly stupid advertising and lack of easy access doomed it in the US to a very small group. It fared much better in Japan understandably, and surprisingly in Australia (no giant hand I guess). I developed graphics authoring programs for it that sold successfully in both Japan and Australia.

We need more info about this computer ! If you designed, used, or have more info about this system, please send us pictures or anything you might find useful.



Aaah... this machine brings back memories! Back in the 80s, while Madonna was true blue and Reagan was playing brinksman, I was lugging one of these babies from company to company to install and maintain NEC NEAX2400 PBX systems. We affectionately referred to it as the "Wonk-Wonk" computer, owed to the sound it often emitted while searching floppies. It was big, heavy and built like a battleship. Larger customer bought one, but small NEAX2400 customers couldn''t afford the $6000 US price tag, so we brought our maintenance machine with us on installs. One night, after a long brutal cutover, I was leaving a savings and loan branch with My APC on a hand truck. I was cluncking down a set of concrete stairs when it broke loose! It tumbled down one flight, rounded the landing, and descended another entire flight. Oh Shit! I''m in big trouble, I though. I rushed to the scene, to find the machine largely in tact, with only a small crack in the case. I took it back to the lab, opened it up, re-seated a couple of add-in cards, and it fired up fine! It was heavy and monstrous, but built like a battleship.

I have an APC, and the NCI P-system discs for it. the NCI version worked well.. Im still working on my apple Mac old machines *128/se30/centris/ci etc)getting them all working with the original software.. soon ill be moving on to the aPC..and could really use more 8" software for itIt was working when I got it and i have not yet checked to see what manuals I might still have..but ill try and respond to any specific requests.!

I have the 128K colour dual floppy model, text only although you could load up to 256 custom characters into the CGRAM which could be used as a rudimentary graphics facility, my dad bought this mainly for word processing and business but although it moved between his factory/office and home at times it was mainly used as our family computer, effectively my personal hobby machine and I loved it. My friends had Commodore 64s, PETs, Dick Smith VZ200 and the like, I was jealous of their graphics and sound capabilities but on the whole I liked having a solid business machine running a good BASIC (we used MSDOS 2.11 with MS Basic-86 interpreter, I also dabbled with the compiler from time to time). I was not that competent in assembly language and the 7220 datasheet was gobbledegook to me at the time but I was always keen to try to switch the text card into graphics mode or obtain the graphics card for it. If anybody has such a card and could post to Australia for a nominal fee I would love to try it out. Our machine had a minor fault which was probably temperature related but would only occur occasionally, however any replacement CPU card, etc, would also be more than welcome, as would any well known software since we had basically no software for the machine except what we ported ourselves, the main app we used was "Spellbinder" word processor running on a daisywheel that my father had rescued from scrap and fitted with a serial interface, he then created font tables etc for Spellbinder. Very awesome.
