UniSite Programmer and modules

UniSite terminal showing version 8.4, 8 megs of ram and 68 pin drivers

UniSite system disagnostic test showing all systems have passed including the MSM.

TaskLink for Windows version 7.00

The communication setup using the remote connector.

This is my UniSite programmer with all it's accessories.

Model # 991 0014, Part # 901 0058 013, Serial # 20002454. This unit was upgraded to version 013.

Initailly the power and self-test is on. The self-test will turn off within a few secons to several min. depending on options installed.

You can see the power on light in the upper right and the ready in the lower left.

SetSite installed.

Full compliment of 17 PinSite modeules.

Back side showing the nylon space adapter to stabilize the PinSites. I have seen this missing on many UniSites with these modules.

All PinSite modules removed. This ia also they way it would look without the PinSite option.

Main board removed showing the dual floppies and the hard disk module.

The pencil points to the cable pugged into the disk connector on newer boards and memory exp. on older ones.

Main board top side.

Main board bottom side.

PLCC base

PLCC base backside

PLCC modules.

Individual PLCC modules available, all 7 of them.

Site 48HS high speed module

Site 48 module.

PinSite adapter used with the PLCC, SOIC, PPI etc. adapter. At this time I do not hace the SOIC or PPI adapters.

SetSite adapter.

PinSite modules used with the PinSite adapter. There can be from 1 to 17 depending on your needs.

PPI adapter for use with UniSite PinSite module.

PPI adapter backside.

Three PPI adapters; 44 pin QFP, 160 pin QFP and a 68 pin PLCC.

SOIC base

Individual SOIC modules available, all 7 of them.

Older style UniSite, no MSM only memory expansion.

Old Style main board with memory soldered onto board, lower left.

Memory expansion board.

These units are frequently on eBay and do not work.  They will tell you the Self-Test passes because the light stays on, WRONG!!  If it does not go out there is a problem, either hardware or software.  Without the 17 PinSite modules and no adapters installed the self-test is about 10 seconds.  As you add PinSite modules the self-test takes longer.  With all 17 modules plus the Site 48 and PinSite adapter the self-test takes about 5 minutes. If the unit does not have a hard disk then a floppy boot disk is required to complete the start-up and the self test light will go out. If the unit has a internal hard disk then the the self test light will go out if everything is working without a boot disk. I use a standard IBM PC 9 pin to 25 Pin serial cable to communicate with the UniSite.

Data I/O used two revisions of logic boards in the UniSite series. The early revision, as present in programmers with revision codes -001 through - 011, did not support the hard drive option and required the memory expansion board to go beyond 1MB RAM. It is easily distinguished, in terms of visual inspection, by the fact that it does not have a pair of 30-pin SIMM sockets in the left front quadrant ('front' referenced to the front of the programmer, or close to the big 60-pin expansion connector if you're just looking at the board).

The later revision, present in programmers with revision codes of -012 through -016 and up, are much more useful. They will support the hard drive upgrade without further modification, and it is also easily expandable in terms of memory.

Most Unisites with the late-revision board will already have their max memory of 8MB installed, in the form of two 30-pin 4Mbit x 9 (parity is required) 70nS SIMMs. If you run across one that has less than this (some models only had 1 or 2MB) it can be upgraded by plugging in the requisite SIMMs, you also need to change out
U91 (a 22V10 PLD) so the Unisite will recognize the additional memory. Click on this link for the .JED file to recreate U91 for this application, it is in a ZIP file format.

If you have to go searching for memory, check at computer surplus places as well as on eBay, they do still turn up. You should attempt to get the types of SIMMs which use nine discrete chips, as opposed to the three-chip models, something to do with refresh timing. Check with me I probably have them in my stash of old computer memory.

You should always go by the programmer's PART number. This has been pretty consistently in the format of 901-0058-0xx, where the two digits at xx are the revision level. If an eBay seller has one you're interested in, and their listing photos do not include a readable image of the manufacturing label, always ask them to send you the actual part number before you buy, and explain the format to them as described above.

 

NOTE: UniSite manual page 2-20 has a listing of LED conditions and their results. Once again if the self test does not turn off the unit is defective and possibly the OS!!

If downloading a UniSite manual I would recommend the XPi version although larger it is more complete. There is very little difference between the the standard UniSite and the XPi version. The only real difference is a version 014 or later board, MSM and a parallel port all other functions are the same.

Please see the last 2 PDF files they will explain how to add a parallel port to your UniSite if it has an MSM module (hard disk). These files plus much of the above information was provided by a UniSite user and more of an expert than I am.
