Look at the light blue DIP switch. Remember those?
I had an 8088 that I bought in 1987. It was a leading edge model D.
The Model D featured an Intel 8088 microprocessor at 4.77MHz, although many had a switch in the back to run at 4.77MHz (normal) or 7.16MHz (high). Earlier models had no turbo switch and ran only at 4.77MHz, while a few of the later ones (seemingly very rare) were 7.16MHz only.
The motherboard came in eight different revisions: Revision 1, 5, 7, 8, CC1, CC2, WC1, and WC2. A list of motherboard part numbers and revision numbers can be found here. Revisions 1 through 7 were usually found in model DC-2011, with revisions 8 through WC2 being either in 2010E or 2011E. WC1 (presumably also WC2) is 7.16MHz only.
They came preinstalled with 512 KB of RAM, user upgradeable to 640 KB.[1] Some had the full 640 KB preinstalled. Some of the later ones were upgradeable to 768 KB.
Some models featured a monochrome/CGA selection switch, with a single port used for both modes. Some models had both a Monochrome and a CGA port, also with a switch to change modes (and ports).[1]
The Model D computers supported a special extended graphics mode, 640x200.
Leading Edge Model D (floppy disk model)The buyer had the choice between a floppy disk model and a fixed disk (hard disk) model. The floppy disk model had one or two 360 KB drives, so that the user could run MS-DOS programs on the primary drive and work with files on the secondary drive, if equipped.[1] The fixed disk model had one 360 KiB floppy drive and either a 10 MB, 20 MB, or 30 MB hard disk.
The buyer also had a choice between an amber or a green monochrome CRT monitors.
The price was about $1600. I paid $1,800.
Mine was OVERCLOCKED to 7mhz and upgraded to 640K. (I was a nut with computers even back then!) Of course I had the CGA - 4 Color monitor!!
Later on I got a 1200Baud modem and hooked up to the University of Arizona's BBS using KERMIT. Now all you young'ns go Wiki that stuff.
I sold the Whole kitten caboodle for $400 in 1992. (Had a printer - a dot matrix epson that we did our Turbo Taxes on. )
My next computer was a $3,000 engineering workstation - a TriStar - the complany is still in business. I still had the tower case and threw it away about 6 months ago. It was big, stood about 3' tall, had 8 drive bays, a screaming (For the time) 386 processor, and 64K RAM. a 60mB HARD DRIVE, and a CD rom drive, an EGA video card
