Your 3853A page, Yes, Indeed I have. It's a great reference as I have referenced it others who are learning about it. could you let me know what enclosure parts are available for building two of your hp drive project please? If not, a drawing? I probably still have all the microchip development tools necessary to burn the chip. I'll email you too. patrick.

I have thought about a full kit, but doubt that it would be worthwhile economically.  The 3852 is nice, did you see my 3852 page?  http://www.dalton.ax/hp3852A/ Please send an email to projects@dalton.ax and we will work out the details!

AndersG, have you thought about have a full full kit at some time. I would most certainly like to collect all the necessary items to have it completely in the case as shown in the videos.

AndresG, Yes, I would like two, please. I could pay by PayPal. 2244 SE Airport Way Suite 100 Redmond, Oregon 97756 -USA- I'm an engineer that, in the days past, designated embed-like devices for various industrial products. One such universal floppy controllers. I had one for sale at one time for the Apple called the FDC-10. It allowed the Apple][ to communicate with the rest of the world with 5.25 and 3.5 disks as it used the normal IBM system 32 physical formatting. Now I do lots of embedded work with mission specific low power and batter driven products. I guess what I'm saying is, I shouldn't have too much trouble getting this up and going. I have an 8753A/C that is used more often (option 010 is the ticket) than one would think prudent these days and have had multiple issues with the hp9122C drives being not reliably suitable. I also have a small fleet of 3852As with all the updates and 1Mb of main memory and, from your initial information, have written a number of programs that run on the main unit as well as interact with it via a PC host and are finding them very much fun, educational and in fact professionally useful. I am working on a JS / js.node project that allows us to freely communicate with these misunderstood and ignored legacy tools. The aim for this is to allow universal communications to them and have the data be archived, processed, shared and richly displayed on modern PC's, Mac PC's and UNIX derivatives. Patrick McLaughlin

Charging multiple serial connected Li cells is a story on it's own. With a build-in BMU you must know how much charging current this unit can handle in case one of the cells is bypassed. Better is connecting a BMS from the charger to control the equalizing current. As free byproduct all information of individual cells is known. This level of discussion tends to go to writing specs. What will be next step?
