ARM-10 variants - they share only the name

==ARM-10 variants==

So, it appears that there three (at least) different kinds of ARM10:

* MIT-AI's second moby was apparently an ARM-10, but it was very definitely different from the ARM-10L (one of which MIT-MC had);
* The ARM-10L: there's an image of one [https://www.computerhistory.org/collections/catalog/102691296 the CHM has/had] (image [https://archive.computerhistory.org/resources/physical-object/ampex/102691296.lg.jpg here]; inside [https://archive.computerhistory.org/resources/physical-object/ampex/102691296.1.lg.jpg here]);
* Eric Smith's KL was [http://www.brouhaha.com/~eric/retrocomputing/pdp-10/ reported to have] an "Ampex ARM10 external memory box, which provided four megawords of ECC-protected semiconductor memory (using 64K DRAMs) [which] attaches to KI10-style memory busses via the DMA20 memory bus interface" (definitely different from an ARM-10L, which was a core unit)

There nothing about Ampex memory in the [http://www.bitsavers.org/pdf/ampex/ Ampex folder at BitSavers], and Web searches turn up very little too.

Clearly, all very different devices, sharing only the ''name'' 'ARM10'. [[User:Jnc|Jnc]] ([[User talk:Jnc|talk]]) 20:46, 20 April 2021 (CEST)
