least it is to me. I'm trying and failing
miserably to find an XT with a 64K
motherboard, purely because I guess people upgraded them as soon as they
Was there such a thing? I thought all XT motherboards used the 64K DRAM
chips. The 'stnadard' version has 64K-256K on board, there's a well known
mod to put 256K chips in the first 2 bnaks (giving 256K-640K on the
mainboard), IBM later sold boards like that.
Actually, come to think of it, I think the address decoder PROM on the XT
motehrboard would support 4816 (16K bit, 5V only) DRAM chops. But AFAIK
no such boards existed.
