This computer has kept for many years my BBS “Hidden Power / Nightfall HQ” up until closing, previously the BBS ran on the Amiga 1000 … then A500 and A2000.

I also publish two historical photos of my “BBS Room” where you can see this Amiga 3000 running.

I give a brief description of what was done and what i did today for this computer.

• Year 2001 i have removed the battery and one of the two SCSI Harddisks that was dead.
• Year 2010 i have cleaned the external/internal case and published the photos on the blog.
• Year 2018 i have cleaned the keyboard.
• Year 2019 i have carefully cleaned the motherboard that was covered with a sticky layer of Nicotine (in the BBS Room peoples likes to smoke a lot)
  • Cleaned the Floppy Drive covered inside and outside by a sticky layer of Nicotine, to repair it i had to completely disassemble it.
  • Replaced the Kickstart ROM 2.04 with version 3.1
  • Removed the last died SCSI Harddisk.
  • Installed “new” 250Mb Quantum Maverick SCSI Harddisk.
  • Installed WB 3.1 and MagicWB + a couple of Demos and of course Pinball Dreams Harddisk version.
  • Replaced the WD33C93A SCSI controller chip with AM33C93A-16PC.
  • Cleaned the Keyboard pcb and replacements of the rubber pad, more than 20 keys are died.
  • Removed the Zorro BSC / Alfa Data MultiFace Card 3 (multi Serial) card and installed the Village Tronic Ariadne II (Ethernet Card)

Everything works perfectly as you can see from the photos.

I received as a gift… we start badly,i have recover, we are not there, i purchased, much better, yet another computer from Radio Shack that was missing in my collection.

The computer equipped with several manuals and Floppy Disk was given to me by a dude (thanks Scott) from the United States, he had written “near mint” and is this phrase that attracted me.

The Computer is a Radio Shack TRS-80 Model 4 (GATE ARRAY) therefore of last production with cathode ray tube with green phosphors.

The seller was not joking saying that it was “near mint” and working, the computer is kept very well it almost seems like it has never been used, it can be observed from the cathode tube, from the pcb of the monitor and from the flyback transformer, keyboard, External and internal Case and from the power supply, the usual ASTEC, which has never warmed up, perfect.

The warranty sticker was also intact.

Since there was nothing to clean/repair i have made some hardware enhancements and little replacements.

What i have done:

• Replacement of the 3 filter capacitors (RIFA) which i usually remove and i don’t replace.
• Converted the ASTEC power supply from 115V to 230v because this version of the power supply allows it because has a 115v/230v switching.
• Replaces the 115v power plug with a schuko.
• Various labels to identify the computer has been converted to 220v.
• Installed 64k RAM to update the Model 4 to 128k (blue wire mod as well)
• Dual ROM to BOOT from FreHD or from Floppy Drive. I have used the Jim Brain ROM-el 2364 which uses a Flash ROM (AT49F001AN) but with a standard Mask ROM 2364 pinout.
• Installed a switch for Dual ROM hidden in the ventilation slots without drilling the case.

All test are made with the FreHD interface by Ian Mavric.

This repair was done only for a personal challenge, the computer is still unstable and with several died components.

After a careful cleaning the computer presents these problems:

• TED MOS 8360R2 not working (keyboard doesn’t work) even if i replace the TED doesn’t work, TED also tested on a working C16 doesn’t work.
• PIO MOS 6529 need to be replaced. The keyboard doesn’t work.
• CPU MOS 8501 Dead.
• Joystick ports (see photo)
• Cartridge connector need to be replaced.
• Modulator without lids (Above and Below)
• The sockets of TED and CPU should be replaced.
• Other rusty pieces.

I have received from a friend two Sinclair ZX-81 to repair and taking advantage of the “sinclair” moment :-D i have also repaired one of my ZX-81 that is died staying off for years :-(

Two out of three ZX-81 have the ULA dead, while the third had a dead membrane and some short circuits caused by someone who don’t know how to unsolder/solder properly.

I have recovered the ULA from this last one and repaired the better one of the two ZX-81, i have also installed the Video Composite mod using the ZX8-CCB kit.

I have also repaired my ZX-81 always with the ULA dead and installed the Video Composite mod using the ZX8-CCB kit.

I thank Marco Lucarelli for giving me the Video Composite mod and giving me one of the two ZX-81 (without ULA / dead Membrane and short circuits) for spare parts.

Jean-François DEL NERO (who’s behind the HxC SD Floppy Emulator) recently has released a version of the HxC emulator firmware that is compatible with the STM32 chip used in the Gotek floppy emulators.

This means that the great functionality of the HxC SD emulator is now available on cheaper and more widely available hardware.

The bootloader to convert the Gotek floppy drive in HxC compatible must be purchased on the website HXC 2001 by sending an email to Jean-François DEL NERO. The price of the bootloader is one-off 10 Euro per Gotek that you want to update. Future updates of the software are free and can be made from a USB stick

The HXC Usb (Gotek) firmware supports: + many more….
