My Model 4 stopped working. It was originally Lance Wolstrup’s, but when he passed away his Widow asked me to take it. It had 4 drives, an amber screen, and some unknown upgrades. Additionally, when I tried to open it up, I ripped out some a wire from an unknown board.

Since diagnosing this was beyond me, I sent it to Patrick at Texas Tandy Restorations.

Patrick got it working, including determining that it had a Seatronic Super Speed-Up Board with 1MB of RAM.

What else was wrong?

• The cable where the HRGC would normally be connected was ripped out
• The left over connector on the 34pin port was broken and needed to be replaced
• A capacitor right had a broken leg (was touching but no longer soldered in place)
• The floppy drive controller cable and WD1793 needed to be replaced
• The PSU had cracked solder and cracked RIFAs
• Loose wire on character generator
• h,i,j,k,l,m and o keys were not working
• Capacitor on one of the drives was broken
• 3 cold solders had popped
• FDC chip 7416 was blown
• CPU was 6Mhz but needed 8Mhz

And of course, he cleaned it. Look at how white it is!

THANK YOU PATRICK.

John Gruver pointed me to an article about Stephen Cass upgrading his Model 100 with a modern microcontroller.

The article can be found here.

Glenn Emelko, author of “BREVI-T” (a command line abbreviation processor), EXTENT-80, and co-author of AIDS-III, is looking for a copy of the instruction card which came with “BREVI-T”.

The software and manual are both missing from the Software Archive so if anyone has the software, manual, or instruction card, please reach out.

Thanks!
