Sys80 Universal Tester (Gottlieb System 80 Diagnostic Tool)

This is a Sys80 MPU diagnostic tool inspired by Leon Borre who wrote a test ROM for System 80 MPUs. In recent years, Marco Albus developed a much more thorough test ROM and worked in a similar manner (blinking an LED at the same address line as Leon's ROM). The fantastic news is, many people have been using Marco's test ROM with awesome results, so this is no longer being considered "experimental" like it once was.

PLEASE NOTE THE FOLLOWING..
THESE BOARDS ARE NOT OFFICIALLY SUPPORTED BY PINITECH. We did not write the test ROM code. If you are having issues or questions with the hardware we can help support that end of things -- but as far as interpreting LED flashes or how to get your non-working Sys80 board up-and-running, you'll be on your own. I highly recommend using Marco's test ROM with this tester if you will be purchasing without the EPROM.

DISCLAIMER: AS WITH ANY TEST EQUIPMENT, THIS TESTER IS USED AT YOUR OWN RISK. We do not know the conditions of boards you are testing or your experience with connecting equipment at the bench. We will not be held responsible for any damages whatsoever that could come from use or misuse of this tester.

Fully Assembled Boards are tested before they are sent out. If purchasing without the eprom(s) you will need to download Leon's ROM @ http://pinwiki.com/wiki/index.php?title=Leon_Borre_Gottlieb_System_80_CPU_Board_Repair or contact Marco (User "MarAlb" on Pinside) for his test ROM & instructions. Marco's test ROM is recommended as Leon's is very basic and has a number of inconsistencies with what's in the documentation. Once you download a test ROM, you will need to use an eprom programmer to burn it to a 2732 eprom. We also have options of purchasing the assembled board WITH Marco's eproms.




Gottlieb System 80 Universal Tester:

$26.95 - ASSEMBLED **WITHOUT EPROM**
    You would need to provide your own 2732 eprom(s) and program either the Leon ROM or Marco's ROM

$32.95 - ASSEMBLED WITH SINGLE "MARCO EPROM" 1X 2732 EPROM
    RECOMMENDED OPTION. Marco's test rom is highly recommended for use with this tester.

Assembled boards are fully tested & can be purchased ready-to-go with ROMs installed for those not into the DIY route.

Options



MARCO TEST ROM (MAIN TEST EPROM)

This is the main test ROM that can be purchased with the Universal Tester (above), but is also offered as a standalone eprom for purchase if you already have a Universal Tester and just want Marco's TEST ROM.

$7.95 - MARCO'S TEST ROM (MAIN EPROM) FOR UNIVERSAL TESTER



EXTENDED TEST ROM (MARCO PROM2) FOR ADDITIONAL TESTS

These are additional test EPROMs that goes into the MPU's PROM2 socket (on later boards where PROM2 is socketed) that allow for a few additional tests. There is a 2716 version that works with all Gottlieb MPUs *except* boards used in Excalibur, Big House, Bad Girls, Hot Shots & Bone Busters. For those games the 2732 version of the extended test rom would be needed. Older System 80 boards that are still using 2 masked roms (ie. soldered to the board from the factory) that have not been replaced with eproms WOULD NOT be able to use the extended test rom without modification for the 2716.

The bulk of the testing is done with the MAIN eprom that is used in the Universal Tester board (as sold above). Most people probably won't need the additional EPROM(s) to figure out their issues, however it does offer some additional testing capabilities. See the Quick description of the tests further down this page for a description of what the PROM2 eprom would test. Please remember that PROM2 is not plug-and-play on some boards & both versions would be needed to cover all Gottlieb boards (as noted above).

MARCO PROM2 for Additional Tests

$7.95 - MARCO'S PROM2 FOR GOTTLIEB SYS80A 1X 2716 EPROM

  • Optional test eprom for use with the Universal Tester when Marco's test ROM is installed and allows for a few additional tests.
  • For earlier Gottlieb boards that have a socket at PROM2. May require modifications to MPU board to use.
$7.95 - MARCO'S PROM2 FOR GOTTLIEB SYS80B 1X 2732 EPROM
  • Optional test eprom for use with the Universal Tester when Marco's test ROM is installed and allows for a few additional tests.
  • For Gottlieb System 80B boards only! May require modifications to MPU board to use.

Options



Quick Description of LED Blink Codes for Marco's EPROM(s):
1 long flash -> test eprom is running
1 short flash -> 5101 has been tested 3x with different patterns over its full range
Burst of 2x short flashes -> Memory in switch matrix (RIOT U4) has been tested
Burst of 3x flashes -> Memory in display (RIOT U5) has been tested
Burst of 4x flashes -> Memory in solenoid/lamp (RIOT U6) has been tested
--------- extended tests (only if optional "MARCO PROM2" is installed) ---------
Burst of 5x flashes -> Socket PROM1 is okay (PROM2 on Sys80B boards) as are address/data signals running to the socket
A long flash, followed by a short flash -> All timers in switch matrix (RIOT U4) generated 4 interrupts successfully
A long flash, followed by a burst of 2 short flashes -> All timers in display (RIOT U5) generated 4 interrupts successfully
A long flash, followed by a burst of 3 short flashes -> All timers in lamp/solenoid (RIOT U6) generated 4 interrupts successfully
*Note: Test program will stall if one of these extended tests fail
-------- end of extended tests ----------
I/O test for the RIOTs to allow for testing of signals at RIOTs (continuous steady led flashes will occur at this point)
