> Do you really need 32k? It takes a lot of current and that is hard for the old powersupply.
(-: "need" is a funny word when working with these old machines! But I went through my power supply pretty thoroughly, and it seems to be up for the job - especially since my PDP-8/e spends most of the time "off". I also installed an air filter on the left side of the PDP-8/e, to clean the air that's being pulled into the machine. It is surprising how much dirt the filter collects! Should help keep the power supply healthy.
I've got my OS/8 set up so that it sees only 7 fields, with the 8th field (field #7) occupied with my own MEMON-8 monitor program - along with the TD8-E boot ROM. MEMON-8 is a stand-alone program that lets me poke around in memory, and read and modify DECtapes on a tape block basis. MEMON-8 also allows me to transfer whole tape images onto and off of DECtape, using the Xmodem protocol (which provides flow control without additional software on the PC end). I used MEMON-8 to load images of the DEC OS/8 distribution tapes from pdp8.net
(in .TU56 format) onto reformatted DECtapes. I also use it to create .TU56 tape images of my own tapes as backups. (MEMON-8 code and user's manual is here: https://tinyurl.com/uvg2lwq
Speaking of power supplies, the power supply in my TU56 failed recently - one of those 6-terminal bridge rectifiers died. I replaced it with a more conventional 4-terminal bridge (massively overrated because that is what I had), and the tape drive works fine again. But I'd love to find a correct replacement for that bridge. The dead one is a Solitron G797. Does anyone have any idea where to find such as thing? I know they are terribly obsolete...
