Hi folks,
I guess people have looked at the pdp-8/m-2 Chassis:
http://hisdeedsaredust.com/pdp/pdp8m-2/04112008359.jpg
There are some interesting goodies as it's completely max'd out!
It appears to have 3x8K memory (a stunning 24K!).
M8320 = OmniBus Bus terminator loads.
G111 = 8K Memory.
M849 = Memory Shield.
M8357 = RX8E (8" Dual Floppy controller).
M8650 = Teletype control.
M847YA = Hardware Bootstrap Loader.
M8350 = Posibus interface (surprising).
M837 = Memory Extension / Timeshare.
M8300 = CPU Regs.
M8310 = CPU Regs Ctrl.
M8330 = CPU Timing.
It was last tested (amazingly) as late as July 1990, a mere 18 years ago.
Again, I'm wondering who took the pdp-8/m: Was it the Surrey Museum or Peter?
Also Peter, you said it was a simple circuit, do you have the circuit diagrams and
procedure for converting a normal PC-based 5.25" Floppy drive to work as an RX-50? I
did use PUTR recently on a PC to transfer RT-11 to 5.25" disk so I could install it
on my pdp-11/73 (before the PSU failed!); so I know they *can* be used in some sense.
Also Johnny, are you actually offering a pdp-8/m or /f!!!!?
I've already handed out a couple of 8/m and 8/a systems over the years.
I didn't plan on splitting with any more, but I might be convinced to
part with one for some other "fun" hardware.
Johnny
