- from work for free, but it only had 256K on the motherboard and no
- expansion (read: USELESS). We got an 8-bit memory expansion card with 3
- banks, filled 2 banks with 256k drams and one with 64Ks, and... it did not
- do anything. I tried switching out some banks on the motherboard and
- setting the start address of the card down farther. nada. Finally, I
- removed the 256s from the card and exchanged 2 banks of 64s on the
- motherboard for the 256s. nothing happened (this is wierd - how can thew
- system treat 256s like 64s?
- Anyway, I'm fresh out of ideas. My parents want to get a 286
- motherboard, but I thought I'd ask the net first and see if there was any
- way I could get this to work. In case it's important, the system is an
- original IBM XT, the motherboard says "64-256k system board" on the side,
- and there are 4 banks of ram chips on the motherboard, each with 9 chips.
