I would personally prefer Holtek HT42B534 over FTDI or Prolific though, as that chip implements a proper USB CDC ACM protocol stack.

Just as curiosity, do you know any brand that manufactures using that controller or is only DIY route too?
That is a relatively new line of products, so AFAIK there is no brand currently using it in USB to serial adapters. It has internal EEPROM for customization which includes VID and PID, so that makes detection a bit difficult.

I will send you a PM one of this days if I wanted to experiment for you to help me, since it looks like you have more hands on experience that I have on this new solution.

Indulging my self to replace my almost a decade old desktop P&S Panasonic camera, as P&S has good/decent DOF for close-up shots (smallish sensor), also can be remotely controlled wirelessly thru my android tablet, this helps a lot for my aging eyes, especially peeking thru the small screen when doing close-up shots.

Also handy at bright outdoor occasions, as it will beat the hell out of those so called phone cam  ::), still pocketable sized, and packed with 30X optical zoom, at 720mm (35mm film cam. equiv.).

Advantest R6581T  :)

Those input jacks are very fragile! The plastic is so brittle on mine that I have to use certain banana plug styles only.

Before you calibrate/adjust it, I'm curious as to what the time stamp from the previous adjustment was (to find out the drift over time). You can access it over GPIB it's in the manual somewhere...I only found out about it after I adjusted it, as you do...  :P

A few bits and bobs... A pair of NOS Intel P8291A GPIB ICs and a few Samsung 16x2 LCD displays.

It should yield interesting projects.


P8291A... Maybe add an AT90USB1287 in there and you can get a USB to GPIB adapter?
Yeah, that is my intention. Just for familiarity, I would go for a MSP430F6x or a TM4C129, though.
You need to mind logic level compatibility though, as 8291A uses 5V while MSP430F6x and TM4C series both uses 3.3V. The whole reason of suggesting AT90USB1287 is because that is also a 5V chip, allowing use of 74HCT573 and 74HCT245 at 5V for bus latching and buffering with logic level conversion (5V NMOS to 5V CMOS.) Otherwise I would say something like STM32F103ZE or AT91SAM9260. (AT91SAM9260 can run Linux, so it is better to use that as GPIB to LXI than GPIB to USB.)

Another interface chip I ran across is WCH CH367, a PCIe 1.0 x1 to ISA-like bus bridge chip with 5V tolerant I/O pins. You can use that to build an PCIe GPIB card if you disable its DMA features.

A free flu shot... And two days off. It would be perfect if I still can move my right arm - I rather not have the two days off.

Since we are talking about medical items.  I had an angiogram the other day.   Seems I had a silent heart attack  :o

Health insurance paid for it all

I never really experienced the "normal" heart attack symptoms either. In fact even the hospitals emergency department conducted some basic tests and initially declared that there was nothing wrong.   ::)

It was only after my friend stated that we were not leaving until they did their job properly that they bothered to hook me up to the ECG, after which I was rushed to theatre for a heart operation.   :o

We need to find a proper cure for doctors, some really are fucking dangerous.   >:(

It is probably a good thing to get regular medical checkups so problems can be caught before it blew up in our faces. It is also a good idea to get health insurance that covers that too.

Meh, just deal with it. You're not an unique snowflake but a slowly rotting mass of meat like everyone else. If you die without feeling anything... well you're dead. If however you know you'll be crippled or dying of incurable disease then instead of crying about it maybe do something to cause as much chaos as possible before you go?

I just bought an Agilent 34410A... I'm so excited! Supposedly in fine condition. Should arrive Wednesday so I'll soon see. Cost £360 total; I think that's a good deal (I hope).

6.5 digits... oh, the luxury!

I wonder if it is possible to program that D87C51 using regular SDCC...

Most likely, that's one of the things I intend to try...

I have to wait for a cheap eprom eraser from ebay to arrive though, I was hoping the 405nm LED lamp I use to cure my SLA 3D printed parts would work, but nope...

I initially just wanted the 2732's to play with modifying/translating the monitor ROM on an 80s 6809 based teaching computer I have, but got carried away :P

I wonder if it is possible to program that D87C51 using regular SDCC...

There was around 2001 a patched version of SDCC, indirectly promoted by Dallas Semiconductors/Maxim Integrated, for the new (well it was a "new" event in 2001) DS80C390, a fast 8051-compatible redesigned processor core able to executes 8051 instructions up to 3X faster than the original for the same crystal speed, and able to support a maximum crystal speed of 40MHz, resulting in apparent execution speeds of 100MHz.

This monster was the core of their TiniJava(1), a Waba embedded platform coupled with a Java1 compiler and a technology called "Jump51", which was able to automatically "adapt" the JavaByteCode to the natural intel 51 code for all the critical low level sections that need some "speedup".

It intriguing, and interesting, but it was not a success, hence they pushed their effort to SDCC, which was then "reloaded" by their marketing office for the next gen: the DS80C400 chip!


So, around 2001-2004, as far as I remember, SDCC was able to compile for both of them  :-//


What I mean is: we are on Gcc-v9, and GNU is going to drop the support for Itanium starting from Gcc-v11 as well as GNU dropped the 68HC11 support around Gcc v3.4.6, dunno what SDCC did with 51 after 2004.



(1) if you want to see a pic, I have one board in my lab. It's used as weather station. The manual is about 400 pages of Java1, while the development machine is a Windows95 laptop  :o :o :o
