Got ITT EXRA|Profession Series 10Mhz 8088 Model-No. 401470-007 system from 1987 this week. Smaller form factor than my Redstone XT-Turbo system. I really did n't what another XT class system but one was far to good a deal to pass up. It has a 8087 maths co-processor, 768kb of ram stock, a 720k 3.5" fdd with the controller is on the motherboard, the Microscribe HDD and controller which were removed because the hard drive is dead, mono/colour video, and this is icing on the cake-a Rev2 XT-IDE isa card along with CF adapter with 64meg CF with cost more than I paid for the entire system.
Swiiched video from mono to colour, inserted a PC Dos 5 .02 then MS Dos 5a boot disk and both booted up fine on the EGA monitor I have. There seems to be an issue with the XT-IDE set up. I suspect the problem is the mobo jumper settings. The jumpers on the XT-IDE card are set exactly the same as my Redstone Computers XT-Turbo system which boots up the 4gig bigfoot drive just fine.
minuszerodegrees.net has a service manual for an ITT 8088 system but it is for the 1985 model which has vertical ISA slots. He also has the later MS Dos 3.2. The MFM hdd has Dos 3.3 on written with a red permanent maker. If any one has info on the jumper settings or a pdf of the serviced would rapped to have a copy of it. Mobo part no. is 401452-01A
Any way in general in very happy with the purchase.
There's a glitch in the matrix.

Apparently 32-bit is dead and nobody likes P4s.
Of course, as always, I'm open to correction...😉
