The XLR8er

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.
