Wanted: Arium ML4100 options
by Bill Sudbrink 08 Jun '09

08 Jun '09

I have an ML4100 that has and is serving me well. I have most of the various pods and ROMs for it and duplicates of many of them. Two things I'm missing (based on my reading of the documents) are an RE-016 ROM emulator (with RS-232 interface) and an AB-032 non-volatile memory. Anybody have either of these that they might be convinced part with for trade or cash? Non-working would be fine. I enjoy troubleshooting. Alternatively, any explanations of why they are not very useful or worth having at all would also be of interest. Thanks, Bill Sudbrink _______________________________________________ Techtoolslist mailing list Techtoolslist(a)flippers.com http://seven.pairlist.net/mailman/listinfo/techtoolslist FTP site is: ftp://ftp.flippers.com/TTL/TestEquipment Archive site: http://seven.pairlist.net/pipermail/techtoolslist/

Wierd behavior with simple Fluke script
by Adam Courchesne 02 Jun '09

02 Jun '09

I made a simple block write script so I can write blocks of data to video memory to make it easier for me to find shorted/floating bit lines etc. The weird thing is, as soon as execute it and it finishes I can no longer write to video memory. For example, if reset a given PCB, see garbage on the screen and execute my scrip, writing all 0's to video memory, the screen is wiped clean. (As expected) Then if I try to write values to video mem to place a sprite at a given location ... no luck. Leave the game on.. reset the fluke... and try the same write again, and it works. So something in the script is putting the Fluke into a weird state. Any idea what could be causing this? Here's the script: SETUP TRAP ACTIVE FORCE LINE NO TRAP ACTIVE INTERRUPT NO PROGRAM MAIN DPY-# DPY-BLOCK WRITE PROGRAM EX DELAY ! Get start and end addresses DPY-START ADDRESS = /1 DPY-END ADDRESS = /2 DPY-DATA = /3 DPY-WRITING DATA# WRITE @ REG1 = REG3 WLOOP: WRITE @ REGF INC = REG3 ! DPY-WRITING $3 AT $F ! EX DELAY IF REG2 > REGF GOTO WLOOP DPY-END OF PROGRAM# !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! ! DELAY ROUTINE PROGRAM DELAY REG1=40 0: DEC REG1 IF REG1 >0 GOTO 0 Thanks for any insight, -- -Adam "Please don't judge my God by my inability to follow him" - Chris Mollins =============== www.onecircuit.com www.youtube.com/user/ajcrm125 =============== _______________________________________________ Techtoolslist mailing list Techtoolslist(a)flippers.com http://seven.pairlist.net/mailman/listinfo/techtoolslist FTP site is: ftp://ftp.flippers.com/TTL/TestEquipment Archive site: http://seven.pairlist.net/pipermail/techtoolslist/

UDN6118A vs UDN6118P
by barry2＠shilmover.com 01 Jun '09

All, I found some old Williams display boards with UDN6118P chips on them. I could not find a pdf for them. what are the differences between the A and P chips? Are they interchangeable?

Re: [Techtoolslist] Help troubleshooting a 9010A

Okay, Been working on the units and I am finally getting somewhere. - I blew U1 on the Display board. Anyone know what chip this is? (its the large 40-pin chip) Marking: P8041A 1210 8423 535419 Intel '77 I confirmed that this was the issue by swapping it out between the displays. Display 1: - Missing the bottom right segment on all digits (I believe its segment 'c' according to the schematic, Figure 8-3). Any idea what would cause this? Display 2: - 10th character sometimes disappears, sometimes is faded, sometimes is fine. I traced that this is controlled by U4 (pin 11) and U8 (pins 2 & 17). I can replace both, but which is the most likely problem? Anyone know where I can get U8 (UDN6118A) chips? Thanks for the help so far. Barry --------------------------------- So I got both systems working, on to the next problem. The display on one is missing a few of the lines (mostly the bottom right ones). any idea where to start? The other, the display flashes random characters and beeps. Thing that ticks me off is that it was mostly working (one character was dim) and I unplugged the connector thinking the power was off. What damage did I do?

Thanks Clay, Much appreciated (you coming to the show in 2 weeks?) Barry > Been working on the units and I am finally getting somewhere. > - I blew U1 on the Display board.

Intel 8041 microcontroller... It's a mask ROM part, IIRC (I think the 8741 was an EPROM version). It's similar to the 8048, both of which were predecessors to the ubiquitous 8051... (MCS-51 family vs. the MCS-48 family) Unless someone has managed to extract the code and you can locate an 8741 to program it on to, you're probably stuck with just swapping in one from another unit. (At some point, maybe getting that particular MCU decapped to preserve the ROM would be a good idea...) > Display 2: > - 10th character sometimes disappears, sometimes is faded, > sometimes is fine.

Allegro and Sprague used to make those... You could steal some off of an old Williams pinball VFD driver board, or just type "UDN6118" in on eBay and there will be some there. -Clay _______________________________________________ Techtoolslist mailing list Techtoolslist(a)flippers.com http://seven.pairlist.net/mailman/listinfo/techtoolslist FTP site is: ftp://ftp.flippers.com/TTL/TestEquipment Archive site: http://seven.pairlist.net/pipermail/techtoolslist/ _______________________________________________ Techtoolslist mailing list Techtoolslist(a)flippers.com http://seven.pairlist.net/mailman/listinfo/techtoolslist FTP site is: ftp://ftp.flippers.com/TTL/TestEquipment Archive site: http://seven.pairlist.net/pipermail/techtoolslist/

Matt, That is exactly the info I am looking for. I started to read this manual in more detail and was moving in this direction, but this clarifies it all. Thank you! Barry -------------------- Some of the Fluke 9010a's (mine for example) might be different than these schematics, but you can look here on pdf page 137. http://arcarc.xmission.com/Test%20Equipment/Fluke/9010A%20Base/9010A%20Serv… 0Manual.pdf You should know how to convert Hex to Binary. HEX-08 -> D7=0 D6=0 D5=0 D4=0 D3=1 D2=0 D1=0 D0=0 If it's reporting BTS 8 is failing - then check the 4116 ram chip responsible for D3 - which is at locate U12. If BTS 12 are failing, it means D3 and D2 are stuck. So check U11 and U12 or their buffers. Matt On Tue, 26 May 2009 21:41:10 -0400, barry2(a)shilmover.com wrote: > Hooked up the 2nd 9010A.

Corey, That's the method and manual I am using. I dont see in the manual how to deduce the failed component. It simply states taht RAM is C000-FFFF. Also, for ROM, it only has signatures for up to rev 2A. Mine is 3A, anyone know the ROM signatures? B > I deduced that there is a Read/Write error at C000.
