The MISOSYS Quarterly

The MISOSYS Quarterly, better known as TMQ, was the official newsletter for MISOSYS, a software company based in Sterling, Virginia. It was published by Roy Soltoff, the “system designer of TRSDOS 6.0” and co-founder of Logical Systems (the creators of LDOS and LS‑DOS). The MISOSYS Quarterly was far more than just a company newsletter, and was one of the best technical resources for the TRS‑80 Model III and Model 4.

ED-IT for the Model 4

ED-IT for the Model 4 is a very powerful text editor for the TRS‑80 Model 4. It was written by Mark Reed and was first released on June 17, 1991. ED-IT cost $17.95 and was distributed by Computer News 80 of Casper, Wyoming.

There were many capable editors for the Model 4. Most Z80 assembler packages included their own editors (ALEDIT in ALDS and SAID in MRAS were notable examples). The LS‑DOS 6.3 operating system even included a simple text editor named TED/CMD.

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. 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.
