RESOLVED (Thanks!) WTB: 8039 Microcontroller
« on: March 15, 2018, 11:19:53 pm »
If anyone, particularly UK based, has a 8039 microcontroller lying around in their parts drawer I would appreciate it.

(There are a few on EBAY but they have massive postage charges)

You might have more luck finding an 8049.

I found this eBay auction: #222280275740 which is 8040.  I believe a 8040 is a 8039 but with twice the RAM.

8040 would be ok

If this does not work out, I checked my mcs-48 collection just now and have a couple of 8049's to spare.
They do have an internal 2k ROM program but IIRC you can skip that with a pin setting and it would behave as a normal 8040.
I don't remember exactly, it has been a long time ago (27+ years) since I worked with those chips  :)
If you want I can sent two of them to you for postage fee, have to check with the postoffice.

Very kind.  Two offers!  I have PMed Kjelt so hopefully that will work out.  Thanks both.
