I have acquired some new (NOS I suppose) 82S131 ROM
chips, and am
looking to write some boot ROMs for my 11/34. Specifically, these are
chips that fit into an M9312 Unibus terminator/boot ROM card. I want to
create RX01 and RX02 boot ROMs. In DEC-speak, these are 753A9 and 811A9
part numbers.
The ROM images are available through Don North at
(http://www.ak6dn.dyndns.org/PDP-11/M9312/). Thanks Don!
I have a one-size-fits-all new-fangled EPROM/PROM programmer, and I
thought I had it made when I saw the chips.
Unfortunately, my programmer is too new to handle these chips. Sigh!
I wonder if anyone has a programmer they will either part with; or who I
could send the 82S131 ROM blanks to, for programming.
If all else fails, ping me privately. I am setup to blast bipolar PROMs,
Steve
