There is an upgrade kit for upgrading the original models to 115/125's. It includes the 10 MHz APC processor card w/20 MHz 68881, 4MB of memory and the DMA (buffered) ESDI disk controller. (Note that original models 10 and 20 came with ST506 drives, so the ESDI disk controller will not work with those drives. Original models 15 and 25 came with ESDI drives.) It can be ordered as accessory part number 61X6833. Last I knew, the list price was $2495. -- Charlie Sauer IBM AES/ESD, D75/802 uucp: cs.utexas.edu!ibmaus!sauer 11400 Burnet Road 822: @CS.UTEXAS.EDU:sauer@ibmaus.uucp Austin, Texas 78758 aesnet: sauer@auschs (512) 823-3692 vnet: SAUER at AUSVM6
