PDP-11/93

What I seem to have missed is exactly WHY the 11/93 is your goal as opposed to an equally capable (as far as the software which can be run) 11/73. The 11/93 might be 33% faster, but it will probably cost at least 5 times the price. If you are using a BA23 box, then with 8 available slots, you should have sufficient slots to accommodate everything you are likely to need when at present you don't know what you want to run as software. At the very least, if you have access to PMI memory, then even if it costs a little bit more, you will get most of the extra speed and almost all quad 11/73 (M8190) boards can use the PMI memory. DEC PMI memory is either 1 MB or 2 MB. 3rd party PMI memory can be 4 MB on a single board. On a BA23 box, ONLY 2 PMI memory boards are allowed in front of the CPU of course. By the way, what software do you want to run? And why is the DEC hardware itself important? Jerome Fine
