But in 1984, Compaq's other unsung hero was released, their desktop computer - the Compaq Deskpro. The original Deskpro was an intel 8086 (not 8088) powered PC/XT class workstation with 4x external half-height bays, Turbo, and very high benchmarks to go with it. The Compaq DSM Monochrome monitor was mated to various CGA/EGA cards and could do graphics and text mode - unlike IBM's MDA.

PICTURE	SPECS	DESCRIPTION
Deskpro Model#1/2/3/4	Intel 8086 @ 7.16/4.77MHz 128K-768K RAM Single 360K DSDD 5.25" Floppy Drives CGA Compatible Graphics Card Compaq DSM Monochrome 13" 12VDC proprietary monitor 84 Key Compaq Keyboard MS-DOS 2.1	The original Compaq Deskpro was released in 1984 and came in 4 configurations with various numbers of floppy and MFM/RLL Hard Disk Drives. I believe the 20MB models (HDD) had a full height drive and dual floppies. Most of these seemed to ship with the 12V Compaq DSM MOnochrome Monitor, which was a graphics capable, Amber Phosphor (though green have been seen), monitor that got it's power from a DIN jack on the back of the computer next to the ISA slots that provided high-current 12VDC power to the monitor, making the monitor ONLY compatible with Compaq computers, and no others. The Keyboard used foam-pad keys just like the original Portable, which means most examples you'll find in the wild will have a dead keyboard. You can get replacement pads from TexElec. The case was made by Parkview Metals in texas and while it looks like a standard AT form factor design, it's actually not. The Deskpro "original" design uses a Baby-AT sized motherboard (about 8.5"x11") with eight 8-bit ISA slots. The power supply just has one big ribbon cable coming out of it feeding 4 plugs on the motherboard that get their own removable cables for drives (up to 4). The keyboard jack is on the lower front - a standard XT compatible 5 pin DIN - but it connects to the motherboard in the front via a pin header. Power for the screen is also taken from the Motherboard as well. Drives were mounted on 5"x1" aluminum drive rails that secured from one side with regular floppy drive screws. The rest of the computer was put together with the ubiqutous Compaq-Style flat-head + T-15 torx screws, including ISA cards.
Deskpro 286 Model# 2551	Intel or AMD 80286 @12MHz 256K-10MB RAM Choice of One or two 5.25" disk Drives in either 360K DSDD or 1.2MB HD Choice of MFM/RLL HDDs in capacities of 20MB to 60MB (ESDI possibly an option later) CGA/EGA Compatible Graphics Card Compaq DSM Monochrome 13" 12VDC proprietary monitor, or 15" Compaq EGA Compatible Display 101 Key Compaq Keyboard MS-DOS 3.x	The Deskpro 286 came just a year later and was Compaq's competitor to the IBM PC AT 5170. The earliest machines still used that 12V proprietary power CGA compatible Amber DSM Monochrome CRT. Also following the AT was the change to a regular 101 Key IBM Model "M" style layout keyboard a little later on. The Deskpro 286 changed the case design a little as well, omitting the power LED used on the previous computer to tell you when it was in turbo and PC Compatible modes, replacing it with a large, black keylock that actually physically locks the case and provides and early form of intrusion detection with a switch. It seems the 2551 carried on for quite awhile, running from 1985 to 1990 when Compaq change to slimline, even including some late-era "Greyface" variants where the dark brown bezel surrounding the drives was changed to a lighter gray color.
Deskpro 386 Model# 2571	Intel 386 DX-16Mhz 1MB-16MB of RAM Dual 360K DSDD 5.25" Floppy Drives, 720K and 1.44M 3.5" Options came later and aftermarket 20/40/60/80/120MB early-IDE Control Data Corporation Hard Disks (type sticker on the drive's face) Quadram EGA Graphics Card, later VGA Graphics Optional Compaq DSM Monochrome 13" 12VDC proprietary monitor, Compaq 14" EGA Compatible Monitor, Compaq 14" VGA Compatible Monitor 101 Key Compaq Keyboard MS-DOS 3.31	The myth, the legend, the original Compaq Deskpro 386! It beat out IBM's first 386 release, the IBM PS/2 Model 80, by a full NINE MONTHS. This was a tremendous deal and was one of the things that broke the old saying "nobody got fired for buying IBM". This made it the fastest IBM Compatible PC on the market at the time. The original deskpro 386 still used a small rectangle logo in the old style, with the beige case framing a dark brown bezel. But inside the machine had some changes including the move to early IDE HDDs and later even 1.44MB 3.5" Floppy Drives (Black), and even a Tape Backup Unit Option (kinda' rare, seen on the 20MHz example below). These continued to be produced up until 1989-1990 along side the 286, and the 20 and 25MHz models, so there could be some later "Grey Face" versions. These were also offered with a Compaq EGA and Compaq VGA monitors later on.
Deskpro 386/20 Model# 257x	Intel 386 DX-20Mhz 1MB-16MB of RAM Dual 360K DSDD 5.25" Floppy Drives, 720K and 1.44M 3.5" Options came later and aftermarket Quadram EGA Graphics Card, later VGA Graphics Optional Compaq DSM Monochrome 13" 12VDC proprietary monitor, Compaq 14" EGA Compatible Monitor, Compaq 14" VGA Compatible Monitor 101 Key Compaq Keyboard MS-DOS 3.31	The Deskpro 386/20 comes in 2, possibly 3 variants. There's the earliest ones which have the Deskpro 386 older style, rounded, rectangle badge, and then there's a later version with a larger badge and the later updated logo. There's also a slight possibily this 20MHz variant came in a "Greyface" version just like other models from the 286 onward. The only real big difference between this and the earlier models is the processor speed, and it seems they sold slightly less than the original 16Mhz Deskpro 386.
Deskpro 386/25 Model# 257x	Intel 386 DX-25Mhz 1MB-16MB of RAM Dual 360K DSDD 5.25" Floppy Drives, 720K and 1.44M 3.5" Options came later and aftermarket Quadram EGA Graphics Card, later VGA Graphics Optional Compaq DSM Monochrome 13" 12VDC proprietary monitor, Compaq 14" EGA Compatible Monitor, Compaq 14" VGA Compatible Monitor 101 Key Compaq Keyboard MS-DOS 3.31	The Deskpro 386/25 was the last version of the Deskpro series to use the original AT style case design. It seems a lot more of these were produced in the 1988 and later "Grey Face" variant than any other model (with the 2551 deskpro 286 coming 2nd most built in that design). The 386/25 was released a year later with the SLimline version of the Deskpro - the Deskpro/33.
Deskpro 386s Model#2530	Intel 386 SX 20MHz 1MB-10MB of RAM Slimline Floppy Drives available in 3.5" 1.44M and 5.25" 1.2M IDE HDD (< 528MB), Connor Peripherals Built-In Compaq VGA Compatible graphics Compaq 14" VGA Color Monitor 101 Key Compaq PS/2 Rubber Dome Enhanced Keyboard II MS-DOS 5.00/Windows 3.0/3.1	The Compaq Deskpro 386s was Compaq's first 386SX based machine. The intel 386 SX was a 16-bit External, 32-bit Internal CPU, similiar to how the Intel 8088 used in the original IBM PC was a 8-bit external, 16-bit internal CPU. These were among some of the first "Slimline" machines. The footprint was reduced by 1/3rd, and the case is a little taller than the original. THis also marked a move to a far more PROPRIETARY design. First off the motherboard was not a standar AT sized board, but rather it's own thing, almost seemingly based on the IBM PS/2 style setup. Many things changed on these. First was tool-less access to the inside via a single flat-head thumbscrew on the top cover in back. The new "slimline" floppy drives and components mounted by sliding into the front and being plugged in via access holes in the removable drive cage. Modular power cables were still a thing as well like the previous models, but now there were 5 ports instead of 4. The new power supply ran down the side like most of IBM's PS/2 70/50 models and featured a power switch on the right front of the case with power and HDD LED lights. The system featured 5 ISA Slots, at least 3 being 16-bit. CMOS battery type changed too from the old Tadiran "brick" style, to a Dallas Clock Chip. Hard Disks were usually Connor Peripherals CP-30xxx series HDDs in capacities from 40MB all the way to 320MB.
Deskpro 386s/20 Model#2535	Intel 386 SX 20MHz 1MB-10MB of RAM Slimline Floppy Drives available in 3.5" 1.44M and 5.25" 1.2M IDE HDD (< 528MB), Connor Peripherals Built-In Compaq VGA Compatible graphics Compaq 14" VGA Color Monitor 101 Key Compaq PS/2 Rubber Dome Enhanced Keyboard II MS-DOS 5.00/Windows 3.0/3.1	The 386s/20 looked identical to the 386s, but had a few more changes. These included it being one of the first PC's to use 72 pin Memory, with a maximum capacity of 10MB using 4 SIMMS.

The original Deskpro 8086 usually had 2 floppy drives down the center, and a half-height floppy disk drive or full height drive mounted on the right side bay, with a blanking plate up top. Single drive 8086's usually had the 1.2M drive on top in the left bay with the HDD on the bottom of the right hand bay, and one blanking plate if the HDD was full height, and two if half height.

The most common configuration on the 286 and 386 seen was a single 1.2M Floppy drive in the top of the left bay, and a half-height 5.25" MFM/ESDI/IDE hard disk on the lower right, usually with a large "Type" sticker on it indicating the Compaq BIOS type the drive required (which was often lost after the machine had been in use for awhile).

A fully maxed out Deskpro 386 usually had 2 floppy drives in the top row left and right bays, with a tape drive in the bottom left, and HDD on the bottom right. THis was a similiar setup to what Zenith Data Systems was doing with their own systems at the time.
