Thanks all! The trick was opening up the front panel (I’m used to keylocks that are only electrical and not just physical).
Here’s the HP label with the options: CPU 2103 MEM BP 1713 IO BP 1727 Accessories 12992B 12944B 2102B 12897B 12892B 12746A In opening the panel on the front card cage, I saw that it only had 16K of memory. :-( I’ll see about firing it up and if that goes well (anyone have suggestions for this type of mini?) I’ll see if I find more memory and suitable peripherals. Thanks.
