Yep here are pictures of my Wang. Laptop that is. This the Wang laptop. I believe they only made one model. Wang was noted for word-processing systems and the Wang Laptop is very word processor oriented. It even has a printer built-in. Remove the display and it looks like a typewriter. The Wang laptop was MS-DOS based but not 100% IBM compatible. It would run some but not all IBM software. The display and associated hardware were definitely different. So if you used standard calls to write to the display, your software would work. However, if you wrote directly to the display hardware, it would puke. Definitely not CGA (Color Graphics Adaptor) here. But would run any monochrome text application fine. A friend gave me this system and I used it mainly as 100 digit calculator (custom software) while working on number theory. It works, well at least it did when I last used it. I need to find the external powersupply.
It has a built-in modem, serial port, keypad port and SCSI interface for floppy drives. Yes SCSI for floppy drives. It used an NEC V30 processor, hard drive and up to 720 KB of RAM. The display was detachable for future upgrades (there were none). Starting price in the mid 1980s was $4000!
