The OTP package is identical to the ceramic/quartz package, so no problem
there. The HN462532 is pin-compatible to the TMS2532 as well, so that's no
problem either. Both use a single 50ms programing pulse with Vpp=25V.

You lucky devil! A Dataman S3 (aka "Softy
3")? I saw an S4 for ?165 at a
hamfest. Had there been a bank machine within 10 miles I would have
bought
it.
It would have been a good buy. With the right adaptor , it can also do
several types of PALs, GALS, and other devices. Sadly, my S3 is rather
more limited. OTOH, it cost less than ?165.
But there is some consolation. I'm getting an
Elnec PrEPROM-02aLV EPROM
programmer for Christmas, so all is not lost.
That will certainly do the job.
I can check
the Hitachi data
sheets to make sure it uses the correct parameters for OTP devices,
in case they're different from "normal" EPROMs.
That would be great
- have you got a copy of the TI TMS2532 datasheet,

Aah, but now I'm prepared.
I've started keeping slightly larger amounts of
cash on me at hamfests and I usually take a very close look at all the
stalls before buying anything. BTW, I've got a spare Altera MAX7000
EPM7128ELC84 CPLD if anyone wants it. GBP5 or best offer. It goes up on Ebay
on Friday if not sold.

Except for the "Foul up the programming, replace the chip"
rule.

That's even better. So not only are they pin compatible,
but they're also
read and program mode compatible? Sweeet...
Thanks.
