Homebuilt bipolar PROM programmer for 82S23 PROMs?

Andromeda Research

I have one of those programmers, but I don't have the bipolar PROM adapter. I had one of their early models, which didn't support a lot of the newer EEPROMs and ucontrollers. They have an upgrade policy that gives you a $50 discount toward the cost on the newer EPROM+ programmer. When I called them to buy the upgraded programmer, they told me that they had more of the old carcasses than they could handle, so they allowed me to keep the old model in addition to giving me the $50 discount. Not a bad deal.

don't

Thanks for your advice, Dave. Well, I´d have to program not more than

Well, if someone here has ever built his or her own homebuilt PROM programmer, please let me know.

Thanks, Joachim

Hallo Joachim,

Is it the way how to program the 82S23 you are looking for or are you looking for a ready to build programmer ?

If it's a solution I can program the proms for you but you have to pay for the return post. I am located in Holland.

You can mail me or reply here in German if you want.

Hello KC,

I am actually looking for schematics or better a PCB layout to just built my own homebuilt PROM burner. I know that in Elector 80 magazine (summer of 1980 I have heard) such a PCB layout incl. schematics and description was published. Unfortunately, I don´t own that Elector magazine from these good old days... Does anyone here does?

Thanks for your kind offer. Well, I think that I maybe could arrange a solution with a friendly guy in my area. But that´s not yet absolutely organized or fixed at all.

Thanks. Danke. For the sake of this NG´s readers I will continue in English language. :)

Kind regards, Joachim

I remember that programmer. Could program only one PROM type and one bit at a time. That's an average of 128 bits - and make no mistake. May still have the article somewhere, but only in Dutch. If you are interested, let me know.

Hi Petrus,

yes, if you have that Elector article from August 1980, pp. 17ff with a useable PCB layout for manufacturing a homebuilt PCB that would be great, even if it is in Dutch only. Could you scan it and send it to me? My address in current reply-to field is not valid anymore, but if you could send me to WAPEricsson1compuservede in pieces smaller than 5 MByte chunks I would be VERY thankful !

Thanks a mil and kind regards, Joachim

Take a look at

Cheers!!!

I have a PDF file of what you need from an old Signetics data book.

Post an email that can accept a 1.7 mega byte PDF file attachment.

Hi there,

if you could send it to WAPEricsson1compuservede it´d really be fine.

Thanks a mil in advance, Joachim

Would that happen to be the Generic I programming specification? I've been after a copy of that for ages - I've got a HTMLised version, but it's missing Table 1, which contains the timing and voltage parameters for all the different Signetics PROMs :-/

Think you could send a copy to snipped-for-privacy@philpem.me.uk ?

Thanks.

hi Joachim,

the correct name of the magazine is elektor. They are still very much alive and active, seee

Good luck

Hi Richard,

thank you very much. I already contacted them yesterday (in Germany) and they think they can supply me a copy of the German release of the article for a small fee of ?3,40.

Kind regards Joachim
