The XLR8er (pronounced accelerator) was a speed-up and memory expansion board for the TRS‑80 Model 4, regarded by many to be the ultimate Model 4 expansion. The XLR8er replaced the Model 4 Z80 CPU with an enhanced microprocessor that offered 256K of additional memory (for a total of 384K) and up to double the speed. The XLR8er originally sold for $299.95 (with memory) when H.I. Tech, Inc. introduced it around 1986, but that price soon dropped to $249.95.
One of the most common questions I receive is about how to transfer files from a Model 4 to another computer. Here is one of the simplest techniques I have found for a null-modem cable transfer.
You will need to use a null-modem cable to connect your Model 4 to another computer and run a communications program on both computers. Both communications programs need to be capable of performing YMODEM transfers.
