How do the Model 30 and 5170 compare? They seem very similar from the brief research I did.
I have both a 5170 and PS/2 30-286. Although they both have a 286 CPU they are quite different machines. The AT is slower and...
AT - weighs a TON and a large box! PS/2 30-286 - Small, low profile (Pizza box) and light
AT - 1.2 inch Floppy, PS/2 30-286 - 3.5 inch floppy (non-standard connector)
AT - Graphics card, disk controller, comms and printer all run from ISA cards. PS/2 30-286 - All on the motherboard (VGA graphics standard)
AT - no specific mouse port and large DIN keyboard connector, PS/2 30-286 - PS/2 mouse port and PS/2 keyboard connector
AT - 8 ISA slots, PS/2 30-286 has 3 ISA slots (but the AT usually had to have at least 3 filled anyway)
AT - DIP chips for RAM, PS/2 30-286 - 4 x 30 Pin SIMMS
There are a number of other differences too of course. Expected, as the PS/2 30-286 was released a 3-4 years later than the 5170.
