9010 fan question
by Tony Jones 02 Sep '16

02 Sep '16

My 9010 started making a weird pulsing noise which I tracked down to the fan. Like it was trying to start but couldn't. I've never given the fan any thought before, does it run all the time? It's just two wires off the motherboard (which weren't pulsing per my scope) but these go to some kind of fan sending unit which feeds 4 wires to the physical fan. Is this some kind of temperature control? The fan blades didn't spin easily, quite a bit of resistance so I was assuming the fan itself was the problem rather than the sending unit. I have the model# specs for the fan so I'll look for a replacement but that might be challenging, replacing just the fan part and connecting to the existing grey sending unit may be another option. I couldn't find any previous mention of this in the archives, curious if anyone has been here before? Thanks!

EETools AllMax progammer
by Fabrizio Vasile 31 Aug '16

31 Aug '16

Hi all, I recently bought for cheap an EETools AllMax programmer, sadly it came without the ISA interface card so it's pretty useless.Does somebody have this card for sale? I noticed that PCB of this AllMax has unpopulated room for a parallel Centronics 36 pin connector, a PSU connector and some ICs so I guess it could be upgraded to AllMax+ model which has these features as default.Are schematics (and manual too) of the AllMax+ model available somewhere?I asked EETools but I got no reply. Thanks in advance. --- Questa e-mail è stata controllata per individuare virus con Avast antivirus. https://www.avast.com/antivirus _______________________________________________ Techtoolslist mailing list Techtoolslist(a)flippers.com https://pairlist7.pair.net/mailman/listinfo/techtoolslist FTP site is: ftp://ttl.arcadetech.org/TTL/Test_Equipment Archive site: http://seven.pairlist.net/pipermail/techtoolslist/

by Andrew Finn via Techtoolslist 09 Aug '16

Hi Does anyone have any info / circuits on the 75188 adaptor ( also known as the mc1488 rs232 transceiver) so these can be tested in the ABI boardmaster 4000? There is also a 4116 ram adaptor too so the boardmaster tells me!! Google on this occasion is not my friend as it comes up with nothing out of the whole of the Internet!!! Many thanks Andrew Sent from my iPhone Please excuse any spelling or grammar mistakes as this was sent from my iPhone _______________________________________________ Techtoolslist mailing list Techtoolslist(a)flippers.com https://pairlist7.pair.net/mailman/listinfo/techtoolslist FTP site is: ftp://ttl.arcadetech.org/TTL/Test_Equipment Archive site: http://seven.pairlist.net/pipermail/techtoolslist/

If you cannot figure it out you can bring it over and swap parts between my FTs. The PSU and VFD are common between A and FT. I also have a spare working display processor (not for sale) but we can swap it to test. _______________________________________________ Techtoolslist mailing list Techtoolslist(a)flippers.com https://pairlist7.pair.net/mailman/listinfo/techtoolslist FTP site is: ftp://ttl.arcadetech.org/TTL/Test_Equipment Archive site: http://seven.pairlist.net/pipermail/techtoolslist/

Fluke 9100A troubleshooting
by Ian Eure 05 Aug '16

05 Aug '16

I’m sure some of you noticed a large amount of Fluke equipment listed on eBay recently. I picked up the new in box 9100A, since I’ve been looking for one and I had an offer accepted at a price I thought wasn’t too out of line, considering that it came with a probe and clock module & was new in original packaging. Unfortunately, the mainframe itself doesn’t seem to boot up. When it’s powered on, I get nothing at all on the VFD, no beeps, and the RUN UUT & DISK ACCESS annunciator LEDs are lit steady. I see in the technical manual that blinking UUT/DISK LEDs are a sign of display problems, but I don’t see anything indicating what solid LEDs would mean. I opened it up and found the SCSI card I was thinking that perhaps the HDD wasn’t working, or didn’t have the software installed on it, but I’d expect to see something on the display even if that was the case. Does anyone have suggestions to diagnose further before I ask for a partial refund? Thanks, Ian. _______________________________________________ Techtoolslist mailing list Techtoolslist(a)flippers.com https://pairlist7.pair.net/mailman/listinfo/techtoolslist FTP site is: ftp://ttl.arcadetech.org/TTL/Test_Equipment Archive site: http://seven.pairlist.net/pipermail/techtoolslist/
