Eprom programmer power supply upgrade

I have owned a lot of different programmers but the Dataman 48Pro (Beeprog) is by far my favorite as it's fast, reliable and usb!. I'd even argue it's better than the new version as this one allows the use of standard adapters for non dip stuff. The newest one is far more locked down and forces you to buy expensive adapters.

It's great for the arcade hobby as it'll do oddball proms, pls153s etc, the only problem is it will some times come up with a warning about the power supply not being powerful enough and fail to burn some of these chips. That's because Elnec (Dataman) cheaped out and only included a 1amp power supply, a 4amp is what is needed to cover everything.

Why include a 4amp power supply when you can charge the customer another £100 for a 4amp one later. Well I'm not going to be paying that.

Thanks to Purity for sending me a picture of his original power supply from a Labprog+ which is the same as used on the 48pro. I also confirmed it with a meter but the pinout shown is correct.


So I needed a 15v 4amp power supply and a 6 pin mini din plug. A quick ebay search and I bought this old Laptop power supply for £5 and a plug for £2.50.

 
 Soldered them together and I can now burn any prom without issue for the total cost of £7.50. 😀
