eprom's for sharktuning
I've been speaking with John Speake about using my new Sharktuner MK1 to tune my 1986.5 twin-screw. John suggested a pair of2732A-200ns EPROMs for the data. However, they are not available anywhere.
Can anyone suggest an alternative that would work just as well?
Thanks in advance,

If you have a EPROM burner with an external power supply, there are many 2732 or 2732A variations available. The EZ and LH will work with 100-400ns.
Pocket Programmer III
Used 2732 usually work just fine. Many available on eBay.
Example eBay search:
(2732*,27C32*,AM2732*,D2732*,ETC2732*,ET2732*,HN2732*) (eprom*,chip*,nmos,dip)
You'll need a UV eraser box too. Depending on the eraser, it can take 1/2 hour to erase older 2732 EPROMs, so it's good to have a handful of 2732.

So, 250ns version would be ok? Not too slow?

250ns is fast for the EZ and LH processors. I've used 400ns w/o issue.
The ST-Micros which Ed has linked would work fine, depending on your burner.
Old AMDs are particulary robust, I've found. (Although they are slower to program, and slow to erase.)
