My colleague told me the maximum negative voltage rail is V in our product range. If they are unstable that may well be where to start looking for the problem This item will post to United Statesbut the seller has not specified postage options.
USB will likely limit the total current available to mA. This module breaks when the assembled PCB device under test has a short to the power rail.

I have testing equipment for testing PCBs.
The sockets are ok on all catasheet these too. Please note the delivery estimate is greater than 8 business days. Started off by looking up the pinout for the 42 pin 51xx chip, found the info I was looking for in the mame driver files and pulled in the datasheet. OT a little, it’s just like the VW beetle I’m working on, a pan with a body, and a whole lot of non datsaheet bits in the mix.
This is a bit of a thinking-aloud post as its clear I need to replace thatI am just troubled that its just one-of-many doing the same thing, and yet the board seems mostly happy, if they were all crappy the whole bus would be affected.

On the odd occasion that the board would play normally I had gone over these chips noting what the 74lss367 were doing, and there was no obvious difference between them when the board was working or not.
Back to home page. Once the “too high” level is reached, shut down the power supply and indicate a fault. Now I have a known good working CPU board and Video board I might be able to make some progress with the stack of faulty ones I have here. Read more about the condition.
By the way – this aint the Galaga board that has stinking hot buffer chips, I have a box of boards, trying to match up good pairs of CPU and Vid boards and then address their little issues once a semi decent match is made.

On the scope almost all the outputs on the TTL datasneet look very nasty, my logic comparator fails chip after chip after chip, but the game works fine apart from the constant coin up, it’s even playable, can’t be that much wrong with it!
Am struggling to get a single working pair of boards, I have about 5 CPU PCBs and 5 Video boards, every combination gives crazy shit to one degree or another.
Once I knew which pins were input and which were output I ruled out the dipswitch theory, thats where I got sidetracked before into thinking the buffer outputs looked nasty. If a high-pass transistor is used, then you risk coupling this 60v directly into Vcc, likely destroying everything.
This would remove the pin from the bus and you can see if it outputs correctly when removed. Dipswitches not having reliable effect proven that its not due to the s or the dip blocks themselves.
IC Datasheet: 74LS367
Moved onto the 2 associated custom chips, the 54xx at 6M and the 06xx at 2L. Hmmm, I guess dying ICs can do all sorts of weird things, I guess if the output of the s are tied to somewhere else that’s shokttky, it’ll clean up enough to make things work. Gotta find what’s ‘injecting’ the weird ass in, what’s the output of the next IC in line like?

74LS367 IC TRI-STATE HEX BUS DRIVER
No additional import charges at delivery! At the very least I can use it to go through the vast array of customs I have from other boards, if I can separate the duff ones from the workers I could save myself a lot of headaches. Add to watch list. Visit eBay’s page on international trade.
I do not want to replace modules anymore. Note that this will dump up to 1A per pin into the 5V supply if daatasheet are not used which would be ludicrous. Function over form I say.
Delivery times may vary, especially during peak periods. I’m looking for a solution to make the modules more robust and virtually foolproof.
