I enjoyed this discussion, being not so CRT educated as most people here. I have a Non-Tek scope, the first one I have where the trace ghost is actually noticeable enough to bother me. I started

Awesome! Incidentally, I'm also looking for actual manuals for my stuff, so if you find someone who has more than one copy would you drop me a note off list? Sean

I also did a Nano-based GPIB project, but using driver ICs: https://github.com/qu1j0t3/gpib-adapter

Something to be careful about with the JAMMA extenders; they sometimes tie A & B sides together at the high number end, where the interconnect pins are. I had ICs popping their tops in an FC-501

Mel, I've downloaded some of the PDFs, but not yet all. I have manuals for all my other gear. Many as PDF though I will probably get or print paper copies as that is much more convenient when

The JAMMA extenders have been around for a long time. I made one of them myself even though I already had a Tek TM500 extender. The big advantage of the JAMMA extender is its rock bottom price. It

Best to first make sure if its actually the display controller chip is where the problem is located before looking at exotic solutions. IMO a one time design, development, debugging and building of an

Ah, IC720A, my first love <3 Em 03/10/2019 12:22, tekscopegroup@... escreveu: In cheap microcontroller days, I see no why the entire frequency counter module cannot be exchanged for a small

Well I hope its not the display driver chip, as helpful as Icom America parts department always is, of course there is probably minus one chance they would have this part available. Best bet would be

FYI I've decided to commission the design of an OSHW board to plug onto a $3 Arduino Nano with footprints for a BNC, USB B and either a 2x12 0.1" header or a PCB mount Centronics connector. The 2x12

I have a 7103 rack mount scope , my crt is bad and would like to replace it with a good working crt . I would like to trade someone that has crts and may want one that i have , i have some 5 series 4

Thanks Håkan, It’s really useful to have the service manuals for all of the ‘you can’t repair this, so just send it back to Tek, remortgage your house, sell your car and get the wife a

Hi Reg, Nice acquisition! I have just about every manual for most popular test gear, but all in pdf format. Any good to you? Cheers, Mel -- you can never have enough oscilloscopes, DMMs, valve

I have ordered one. Should arrive in a few weeks. I checked the chip's datasheet - more powerful than the ATMEL: https://www.silabs.com/products/mcu/8-bit/c8051f38x/device.c8051f383-gq It should

BTW I did my extender with a JAMMA edge board female connector and a JAMMA edge board used to retrofit older boards (which before JAMMA standard, every single different game had a different

Thanks for that AR488 info, that looks really good. I was searching for a low cost USB-GPIB adapter. BTW, did anyone ever buy this (looks new on aliexpress), it's a compact open source Prologic

Thanks for that AR488 link, I'm also looking for an affordable USB-GPIB adapter. BTW: did anyone use this? It seems new on AliExpress, a EUR 18 clone from an opensource
