Anyone out there know how to read masked roms with their Data I/O unipak2b? I'm trying to read the two 4k masked proms off of a tailgunner board and make copies of them. But I'm having trouble reading them. First I tried downloading them as 2k roms and combining them.
copy /b tailgunner.P7 + tailgunner.R7 ROM.R7
copy /b tailgunner.T7 + tailgunner.U7 ROM.U7
Then burned them onto a tms2532 rom. Successful, but didn't work in the game. What am I doing wrong? thanks.

Has anyone tried upgrading the RAM in their Fluke 9100? It appears to use regular old 1mb 30pin SIMMs, but as we all know from the keyboard, appearances can be deceiving. I have some 1mb simms I'm going to try but I thought I'd see if anyone had input on this first.

I've upgraded to 4MB using regular SIMs - you need the setup floppy to get the machine to recognize it though. And set the dip switches... John :-#)# At 5:39 PM -0700 6/3/04, Chris Loggans wrote:

What actually is the benefit of more ram for the 9100? Mine has 2mb, but I never have a problem. Mind you, I *still* don't have the edit suite, so I assume the ram must have something to do with that part of it? So, I'll put out my 6 monthly call again.. does anyone have the EDIT suite for sale? Or in fact a 9100 already fitted with the videocard that they'd sell me?

I have a broken pinball motherboard here that I'm trying to fix. I'm using a Fluke to spy on the data bus because it has a line stuck high. Connected to the data bus there appears to be: 1 EPROM 1 RAM 1 Resistor pack A couple of 74HC244's bringing in the switches matrix data A load of 74AC374's driving the transistor-controlled outputs I've isolated the EPROM, RAM and 244's from the circuit and it makes no difference. I don't really fancy removing all the 374's so I thought I'd ask if anyone knows whether the 374 IC would ever fail in a state where it would drive a bus line high from an input to that IC? I could understand an output from a 244 doing it but they have all been isolated. Do resistor packs die very often? Is there a better way of testing for a stuck bit other than snipping the pins of the ICs :-( The processor on the PCB is a 68000 and when I use the Fluke and 68000 pod to check the bus, it says it's OK, but every manual read from the databus gives a stuck bit. Has anyone ever seen the 68000 pod do this? TIA!

Hmm... I would probably be at the point where I'd carefully snip just the pin (for whatever data line) until I found the culprit. How many 374s are you talking about? 4 or 5? That's not too bad and not too much of a hack if you're careful and have good snips. I've never found the bus check on the Fluke to be helpful... ever :-) I take it when you read a given address, you always have this bit set to 1. (I always like to confirm with the Fluke probe sync'ed to data ... makes it very easy to catch a problem when the bit is stuck on the output of a buffer chip, but that doesn't seem to be your problem.) Before snipping, I'd just double-double check. I hate cutting things without knowing for sure that I'm on the right track. But if you're always seeing this bit set at 1, then you're probably right... I've never found a great technique for isolating these types of problems. When you throw your scope on that node, is it always 1 as well?

I would remove the Fluke and manually check the line to verify the short. Check the line both with power off and power on. (One of the gates with an output connected to the line may have something driving it's input such that it's output is pulling the line down. A hard short will be there even with power off.) Then use a HP Current Probe to see where the short is.

Thanks for the ideas guys! I chopped the resistor pack out and that didn't make any difference. I checked the resistance on the line manually, with power off, to +5 and 0V and it was a little different but nothing obviously wrong. So I bit the bullet and chopped out the soldered in RAM that was being used to do the test with and magically the problem went away! It must have been a problem with the WRITING of the data to the RAM (or the input holding the bus line high??). Now I have to fix all the bits that I broke and then see if it works in the pinball table... One more question... the processor is a 68k with an 8MHz crystal. The can I replace the 6264-90 RAM with a 6264-12 one? (I'm presuming the 12 is short for 120.)

I haven't successfully used my current probe to isolate shorts. Any tips? Of course I got it off ebay with no manual, so I just made an educated guess on how to use it.
