What's this?

Release Date: 1/1/1987
Manufacturer: Cordata
Donated By: William Morris
This is one of those rare machines to come along that not too many people know about. We *think* it's an XT portable machine with a 9" screen but we're not sure on the speed. The model # (PPC-400-25) suggests that perhaps it's a 25 MHz machine but if it is, it's probably not an XT.

The machine uses a Seagate 20MB hard disk. Although the screen is monochrome it's actually a CGA graphics adapter built in.

This was the first computer I ever bought in 1989. I was living in Germany at the time. It was like a suitcase with a cover that held the keyboard in place and covered the screen. I remember the big upgrade when I had a "hard card" installed and no longer had to use the MS DOS disc. Amazing.

No one has mentioned it-- the plastic in the 1980s was a lot lighter, closer to a khaki color. The machine looked good! Also, under the plastic you had a lot of metal shielding. So there were actually two layers to the thing. Man, it weighed a lot. I had a SixPackPlus running on my machine. Remember MultiMate? I used to write papers with it. Circa 1985.

I still have my machine mfd by Corona Data Systems but sold under Sperry name. 5 1/4 mono screen, 512Kb RAM, single 5 1/4 disk drive, 40MB HDD. Original disks IBM PC Dos 1.1. Now running MS-DOS 6.22. Fully backed on diskettes. Lol.

I had one of these branded Corona Data Systems, identical to the one shown here. It was a 4.77mhz XT and could take an 10MB Hard Disk (A 20MB disk would work up to 11MBs in and then start getting lost with whirring noises). As has been pointed out already, the screen font was absolutely gorgeous. If anybody has one of these machines still working, I would be very interested in extracting the font data from the ROMs. A beautiful machine but prone to having the keyboard controller blow if the keyboard is plugged/unplugged when the power is on. The keyboard itself was very nice too, very professional feel. The machine weighed a ton though.
