Okay yesterday I was indeed able to work out how to move files between this laptop and the TRS-80 Model 102 I own. It involved DOSbox and a serial cable who used the FTDI chipset and a nullmodem connector. DOSbox was setup to be a slow 80386DX. And running the unique software that the company commissioned I was able to basically do that.
Ironically the disk drives the thing uses, and I do not have here were the same ones that Brother optioned for their knitting machines. The unit uses for memory a 6264 chip which I know is a static RAM chip organized the same as the EPROM 2764. I stuck one of mine in, and it seems to have found it.
But has anyone ever seen a 62128 (Static RAM same as a EPROM 27128), or a 62256 (Static RAM same as a EPROM 27256) someplace?
62256s are common, and are the same format as a 27256, with a slight pinout difference. (A14 vs. /WR vs. Vpp) There are 62128s, but a very different kind, not the same format as a 27128 EPROM. The 62128 is 128K*8, while the 27128 is 16K*8. This is a source of confusion when people compare them to 62256s, which are 32K*8. -Dave -- Dave McGuire, AK4HZ New Kensington, PA
