| − | == MC configuration ==
| |
| − |
| |
| − | So I'm trying to work out MC's configuration. (I know, I know, I could look in CONFIG >, but I'm lazy.) Here's what I remember/can work out:
| |
| − |
| |
| − | * 8 [[MF10]]'s
| |
| − | * (later) An Ampex? 'external' memory box was added
| |
| − | * 3 [[RP04]]'s
| |
| − | * So, therefore, some sort of MASSBUS controller, but since it was a KL10 Model A, not an [[RH20]]; probably an [[RH10]]
| |
| − | * That would have needed a [[DF10]]
| |
| − | * A [[TM10]] of some sort; dunno if that had a separate DF10, or shared the one the RH10 used
| |
| − | * Some sort of high-end DEC magtape drive
| |
| − | * A [[DL10]]
| |
| − | * Later, first one, and then a second Trident drive, attached to the DL10 PDP-11
| |
| − | * The front-end -11 had a bunch of serial lines, probably a [[DH11]]
| |
| − | * CHAOSNET eventually on the DL10 PDP-11
| |
| − | * I'm not sure why they initially acquired the DL10+PDP-11 (i.e. what it did to begin with); probably more serial lines

| − | : I have tried to summarize changes to CONFIG > for all machines over the years: https://github.com/PDP-10/its/issues/1168
| |
| − | : Most of what you wrote seems spot on. I can see there was a third T-300. Yes, initially the DL10 front end was just a normal DC76 handling terminals. [[User:Larsbrinkhoff|Larsbrinkhoff]] ([[User talk:Larsbrinkhoff|talk]]) 17:29, 12 April 2021 (CEST)

| − | :: Ah, thanks.
| |
| − | :: It looks like it doesn't say what kind of tape drive it was; it was a TU77, or something. If we ever get good photos of the machine, we should be able to tell (also, if there was a second DF10).
| |
| − | :: I wonder why they did the whole DL10 thing just to get a few more serial lines. Maybe the DTE20 one was maxed out?
| |
| − | :: I see from the IOELEV/KLDCP source that the DTE20 -11 had a TU56; I vaguely remember that. [[User:Jnc|Jnc]] ([[User talk:Jnc|talk]]) 18:53, 12 April 2021 (CEST)
| |
| − | ::: I only know of one photo of MC when at MIT, the one on the [[ITS]] page, but there's no tape drive. I saw MC in LCM storage, but I don't remember any peripherals. [[User:Larsbrinkhoff|Larsbrinkhoff]] ([[User talk:Larsbrinkhoff|talk]]) 18:59, 12 April 2021 (CEST)
