Hi Hank, I was thinking of just an HPIB external drive emulator, not a universal GPIB interface. By the way the Prologix one you linked to actually works very well, I've used one. I agree a "40 pin"

To begin with a controller would be more expensive and much more complicated.? There has been little success doing DIY GPIB translation, and even some commercial units only partially implement GPIB

Ran across some r/d regarding the failures of the Epson type card and other work by U Conn. including schematic of a novram solution that was tested.

If we want a common design, would a controller and SD card slot in a HPIB connector that simulated a HPIB HDD e.g. 9134D, not be a better solution? This could be common for many other instruments.

The quick setup document in the files section will get you started, but the 8920A-B-Application-Handbook-08920-90126.pdf is more devoted to AM/FM/SSB tests, It also shows the block diagrams which

Ok Thank Ralph I though it would be OK as long as I stay on then 60 watt port but I wanted to make sure before I did something stupid. Jim sorry I meant to say output to the 60 watt port. Thanks for

Spectrum analyzer is used on the? RF I/O port, or over the air spectrum analyzer in the antenna port, DO NOT connect transmitter to the ANTENNA PORT! When you say "output" what do you mean? The built

I have a 60 watt 8294 and have no problem putting a transmitter into the 60 watt port and using any function of the 8294.? It will take 100 watts for a very short time but I would not go over the 60

This project notice was sent out as a special message.? That just means that our members that read postings using the Groups.io web?interface will receive this announcement in their email. Sometimes

I'd like to get an idea of interest in building a DIY card for our HP RF test sets.? Mine takes a regular PCMCIA card, but it might work out that a PCB design for the Epson will be available first.

Reading some comments on the net regarding homemade HP48 cards, it seems that tinned fingers are degraded by being in direct *contact with gold sockets. * Tin and lead are far from gold in the

Hi group, first forgive my ignorances but on my hp8924c I have been using it to align my transceivers, in transmit mode on the 60 watt port I can look at power, frequency etc, but I want to also look

Hank-? Others have complained that tin plate goes flaky. I found where someone was trying to use nonvolatile serial ram with a bunch of support/glue/translation chips in an effort to do away with the

This is a goal near and dear to my heart.? I think as a group we ought to be able to crack this and maybe get PCBs made for both the Epson and the standard SRAM formats.? Last week I ordered some

The edge connector is the same as a PCI card. I did some trials years ago using a PCI riser cable intended for low profile rack mount PD case. Robert G8RPI.

I was trying to ring out the lines from the instrument to the card, and compare my 32k card with the 48 project. This one has a little more to it but not much. Memory is one HY628100b, but the board

I understand the Photos now, you have just lifted the "skin"? of the card and the frame is in place. You will need to identify the IC's used. Robert G8RPI

I don't understand the PCB photos, they appear to be masked or cut-off, but yes a lot of memory cards can be expanded by adding additional chips. Link changes may be required for correct addressing.

I see now.? The HP-48 notes are just the backdrop for the opened Epson.

Aren't those pictures of the RAM card that goes in the HP-48 calculator?
