Is it even possible to add a diskdrive to a PDP8/L ? My 1970 "Small computer handbook" only mentions TU55/TC01 and DF32 as mass-storage options for the 8/L. Both are essentially unobtainable.
Well, yes-ish. I thought about it last night and realized that the pdp8/L *does* have a data break option that can go in the CPU box, but it is for only a single device. For more than one data break device you would need a BM08.
That said, you're still running with only 4k of memory so anything above a DF32 is probably overkill.
