Oh, boy, what a pain these 6351s are! The Unipak can't handle MMI very well at all, gets a few addresses in then quits. It does burn Signetics and other PROMSs just fine. My adapter socket is correct, and I've been talking with the expert on Unipaks/Programming Paks - Al Marin - once of Data I/O and bought out all their early stock and is the sole support site left. He also tells me the early MMI PROMs were difficult to program and they often modified the card so it would get an infinite amount of 33V pulses instead of the three (MMI) recommended. You can't do that with the Unipak though. Sigh! The Unipak 2B supposedly handles 6352s which are simply rewired 6351's BUT that is where I'm having the problem with lack of more than a few addresses per burn cycle.

We've been chatting back and forth for the past few days on these parts and finding a way to burn them. So far I find I have a 6351 adapter for the Programming Pak, but my PP is for the Signetic PROMs, not MMI. Totally different voltages, pulse widths etc.

So - I'm looking for a Programming Pak with Analog and Digital cards labelled 1226-1 (MMI) {mine is 1226-2L (Signetics)}. I have schematics for the 1226-1 cards (MMI) if anyone wants a copy.

I now have all the info I need on the 6351 though, thanks! Burning is going to be a pain though...

Thanks, I find that the old Logicpak PROM programmer is the part required - I have that, and a number of the 715-XXX adapters, but NOT the 715-1036 adapter! So I think I can modify a 715-1039 to do the job though. Just a bit of cut and paste!

Does anyone know if you can plug the 19 series packs into the 29? I suspect so, but will have to read up to find out for sure.

Thanks Bruno,

I'll add it to the FTP site under, um...old parts?

I know that the earlier Data I/O programmers (19?) could handle the 6351, but not the 29/Unipak2 - no code for that one. Curious if an adapter with some hardware will do it. I need these to simplify making replacement PROMs for Gottlieb system 1 MPUs. Hoping to 'corner' the market (perhaps ten proms/year in sales!). So if you want to sell yours cheap... ;-)

Does anyone have the early prom code sheet for the 19? I have the 29 list on the ftp site:

ftp.flippers.com/TTL/TestEquipment/DATA-IO (not well organized I'm afraid!)

Note that I have removed the space between "Test" and "Equipment" now...

I need to double check the part number, but I seem to think I have a bunch of these that I can't program too so I'd be interested to here the details of this adapter :o)

Cheers,
