Since a long time I searched for a way, to write BootProms for my PDP’s like the 11\/34, \/24 and the \/44.<\/p>\n

I was lucky and got 30 Bipolar Proms Signetics (82S131N) in NOS state.<\/p>\n

This type can be written in older programmers, like the Data I\/O 29b with at least the Unipak2. (a Unipak2b is not needed)<\/p>\n

One week after I found the Bipolar Proms, I was able to acquire an Data I\/O 29b in ebay UK, and was happy to be the bidder who got it.<\/p>\n

Packaging was good, the contact and communication was more than perfect, so that the Programmer arrived here after two days on the road via DPD.<\/p>\n

Yes DPD! And it was with about 20 Pound the cheapest possibility to get them to Germany.<\/p>\n

A first check-up and some Cleaning later I have copied a DEC RL01\/02 (23-751A9) BootProm to a NOS 82S131. The Checksum fits, and all was running good.<\/p>\n

5 Minutes later, the filter Cap in the Power Socket has started burning, so that I was in the need to exchange them, in an manner, which keeps the programmer in an original state.<\/p>\n

Some impressions here:<\/p>\n
