Hi All:
I have been lurking for several years, although I was quite active in the retrocomputing
community before that.
Work and other pleasures kept me a bit inactive until my retirement last summer. Just
coming up for air!
I have several old DEC systems, including pdp-8s, pdp-11s, and VAXen. I am getting going
on them again.
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.
Alternatively, if anyone has spares of the these chips (753A9 and 811A9), I can swap you
blanks for them.
Thanks and I am looking forward to becoming active on the list and in the hobby/fixation
again!
