What is this rare multi-user UNIX workstation? (Plexus P/20)
Adrians Digital Basement 2024-05-25 | What we have on the bench is a Plexus P/20 dual processor multi-user UNIX computer from 1985. This was likely designed for office user and support 8 concurrent users in this configuration, with up to 16 possible with the use of an extra I/O processor card. This machine doesn't seem to be documented anywhere other than a simple brochure (link below) so let's see if we can unravel some of the mysteries of this machine.

What about four barn found Apple IIc computers? Could these left for dead machines still work? -- Links Adrian's Digital Basement Merch store:my-store-c82bd2-2.creator-spring.com Adrian's Digital Basement ][ (Second Channel)youtube.com/channel/UCbtwi4wK1YXd9AyV_4UcE6g Support the channel on Patreon:patreon.com/adriansdigitalbasement My GitHub repository:github.com/misterblack1?tab=repositories -- Tools Deoxit D5:amzn.to/2VvOKy1 http://store.caig.com/s.nl/it.A/id.1602/.f O-Ring Pick Set: (I use these to lift chips off boards)amzn.to/3a9x54J Elenco Electronics LP-560 Logic Probe:amzn.to/2VrT5lW Hakko FR301 Desoldering Iron:amzn.to/2ye6xC0 Rigol DS1054Z Four Channel Oscilloscope:rigolna.com/products/digital-oscilloscopes/1000z Head Worn Magnifying Goggles / Dual Lens Flip-In Head Magnifier:amzn.to/3adRbuy TL866II Plus Chip Tester and EPROM Programmer: (The MiniPro)amzn.to/2wG4tlP aliexpress.com/item/33000308958.html TS100 Soldering Iron:amzn.to/2K36dJ5 ebay.com/itm/TS100-65W-MINI-Digital-OLED-Programmable-Soldering-Iron-Anti-static-Structure/113382669853 EEVBlog 121GW Multimeter:eevblog.com/product/121gw DSLogic Basic Logic Analyzer:amzn.to/2RDSDQw ebay.com/itm/USB-Logic-DSLogic-Basic-Analyzer-16Ch-100MHz-4Ch-400MHz-Xilinx-Spartan-6-FPGA/202543965672 Magnetic Screw Holder:amzn.to/3b8LOhG harborfreight.com/4-inch-magnetic-parts-tray-90566.html Universal ZIP sockets: (clones, used on my ZIF-64 test machine)ebay.com/itm/14-16-18-20-24-28-32-40-pin-IC-Test-Universal-ZIF-Socket-Fs/303206721971 RetroTink 2X Upconverter: (to hook up something like a C64 to HDMI)http://www.retrotink.com Plato (Clone) Side Cutters: (Order Five)ebay.com/itm/1-2-5-10PCS-Micro-Scissor-125mm-PLATO-170-Electronics-Cutter-Side-Cutting-Pliers/163458746184 Heat Sinks:aliexpress.com/item/32537183709.html Little squeezy bottles: (available elsewhere too)amzn.to/3b8LOOI --- Instructional videos My video on chip removal without damage:youtube.com/watch?v=XQVjwPsVFd8 --- Music Intro music and other tracks by: Nathan Divino @itsnathandivino
Repair of an IBM PC floppy drive wont read disks (Tandon TM-100)
Adrians Digital Basement 2024-08-17 | This 41 year old single sided floppy drive came from an early IBM PC 5150 and even has IBM branding on it.

Is an IBM PC usable at the same clock speed as an Apple II?
Adrians Digital Basement 2024-08-10 | Ah yes -- I've always been curious how a PC would perform if I ran it at the same clock speed as most 6502 machines including the Apple II: 1mhz.

A brand new XT RAM test ROM and an update on some unfixable parts
Adrians Digital Basement 2024-08-03 | I recently had a number of videos where I struggle to understand why my XT clone motherboard had fata RAM issues that prevented it from working. I tried to fix it but got no where. The same thing happened with an AST RAM card, where it also had random issues that I couldn't sold.

Booting UNIX on the Plexus P/20 didnt go to plan
Adrians Digital Basement 2024-06-08 | It's time to boot the Plexus P/20 into UNIX, or at least try to!

Now it's time to actually try to boot this machine into UNIX and see if it works!

Another broken Mac Plus with some odd symptoms
Adrians Digital Basement 2024-04-20 | On the channel today we have a broken Mac Plus machine which is a come-back. This is a machine I had previously worked on and given to a friend, but it was returned to me broken. Can you guess what's wrong with it based on the symptoms? Unrelated, it seems like a bunch of other channels ha4ve been fixing Mac Plus machines as well, but I can assure you this is complete coincidence. (I had actually worked on this machine before those other videos came out.)

So let's use our eyes (to look at the symptoms) and some math to figure out which chips are actually causing the issues. -- Links Adrian's Digital Basement Merch store:my-store-c82bd2-2.creator-spring.com Adrian's Digital Basement ][ (Second Channel)youtube.com/channel/UCbtwi4wK1YXd9AyV_4UcE6g Support the channel on Patreon:patreon.com/adriansdigitalbasement -- Tools Deoxit D5:amzn.to/2VvOKy1 http://store.caig.com/s.nl/it.A/id.1602/.f O-Ring Pick Set: (I use these to lift chips off boards)amzn.to/3a9x54J Elenco Electronics LP-560 Logic Probe:amzn.to/2VrT5lW Hakko FR301 Desoldering Iron:amzn.to/2ye6xC0 Rigol DS1054Z Four Channel Oscilloscope:rigolna.com/products/digital-oscilloscopes/1000z Head Worn Magnifying Goggles / Dual Lens Flip-In Head Magnifier:amzn.to/3adRbuy TL866II Plus Chip Tester and EPROM programmer: (The MiniPro)amzn.to/2wG4tlP aliexpress.com/item/33000308958.html TS100 Soldering Iron: amzn.to/2K36dJ5 ebay.com/itm/TS100-65W-MINI-Digital-OLED-Programmable-Soldering-Iron-Anti-static-Structure/113382669853 EEVBlog 121GW Multimeter:eevblog.com/product/121gw DSLogic Basic Logic Analyzer:amzn.to/2RDSDQw ebay.com/itm/USB-Logic-DSLogic-Basic-Analyzer-16Ch-100MHz-4Ch-400MHz-Xilinx-Spartan-6-FPGA/202543965672 Magnetic Screw Holder: amzn.to/3b8LOhG harborfreight.com/4-inch-magnetic-parts-tray-90566.html Universal ZIP sockets: (clones, used on my ZIF-64 test machine)ebay.com/itm/14-16-18-20-24-28-32-40-pin-IC-Test-Universal-ZIF-Socket-Fs/303206721971 RetroTink 2X Upconverter: (to hook up something like a C64 to HDMI)http://www.retrotink.com Plato (Clone) Side Cutters: (order five)ebay.com/itm/1-2-5-10PCS-Micro-Scissor-125mm-PLATO-170-Electronics-Cutter-Side-Cutting-Pliers/163458746184 Heat Sinks:aliexpress.com/item/32537183709.html Little squeezy bottles: (available elsewhere too)amzn.to/3b8LOOI --- Links My GitHub repository:github.com/misterblack1?tab=repositories Commodore Computer Club / Vancouver, WA – Portland, OR – PDX Commodore Users Groupcommodorecomputerclub.com --- Instructional videos My video on damage-free chip removal:youtube.com/watch?v=XQVjwPsVFd8 --- Music Intro music and other tracks by: Nathan Divino @itsnathandivino
A Mac Classic with 4mb of RAM without using the RAM expansion card
Adrians Digital Basement 2024-03-09 | After the recent Mac repair-a-thon, I had a Mac Classic motherboard with a missing 74LS174. I thought about just replacing that IC but realized I could actually do a simple mod to the motherboard to give it 4mb of onboard RAM instead of just 1! (And I wouldn't need to replace the 74LS174, so it would actually save me money. -- Info How to modify the Mac Classic for 4mb onboard as seen on Adrian's Digital Basement ** Remove two chips: Remove UL1 CAS PAL (no longer needed!) Remove UH6 74LS174 (no longer needed!) ** Modify system to think it has 4MB on the motherboard: Pin 13 of UI4 BBU: Remove R42 470ohm (under motherboard - this pulls pin to ground) Pull up PIN 13 via 10K to 5V (I did this by running a jumper between the left side of R42 and R41) Pin 17 of UI4 BBU: Should be pulled up to 5v already (verify but mine was already at 5v) ** Remove old 44256 RAM chips (8 of them, UK1-UK8) ** Install 4400 RAM chips (4x1mbit - I took these off a 4mb 72pin SIMM) ** Make connections to connect CAS lines from UI4 BBE to RAM: Connect UL1 PIN 7 CAS0H to UL1 PIN 24 (CAS0H to UK1/3 DB8-14) Connect UL1 PIN 6 CAS0L to UL1 PIN 25 (CAS0L to UK5/7 DB0-7) Connect UI4 PIN 16 CAS1L to UL1 PIN 27 via 22ohm (CAS1L to UK6/7 DB0-7) Connect UI4 PIN 19 CAS1H to UL1 PIN 26 via 22ohm (CAS1H to UK2/4 DB8-14) (22ohm is just to make sure shorted DRAM doesn't kill the UI4 BBU) Remove (optionally) and jumper over R43 and R56 (22ohm resistors) as these are in series with R3 and R19. This gives the CAS lines just 22 ohms (versus 44 ohms) This replicates the Mac SE design exactly, in fact the Mac Classic is really a Mac SE... The UI4 BBU chip is the same one on the Mac SE, even though the part# is different, it seems to work in an identical way. -- Links Mini Mac Repair-a-thon: Part 1: youtu.be/lHvGc4LWR0g Part 2: youtu.be/nSoSX6XV7t4 Part 3: youtu.be/xx08YXkUOnQ Recapping the Mac Classic II Motherboardyoutu.be/rpVAg6hG__Y Previous Mac Repair-a-thon from 2020: Part 1: youtu.be/lKD65I86XGQ Part 2: youtu.be/kNhVQWH318M Part 3: youtu.be/uatqcZRzmt0 Part 4: youtu.be/zC0qi5dQsWs Part 4.5: youtu.be/YikOY8WTnLU Part 5: youtu.be/PHTnauC020o Part 6: youtu.be/mqWCPkfcr1A Adrian's Digital Basement Merch store:my-store-c82bd2-2.creator-spring.com Adrian's Digital Basement ][ (Second Channel)youtube.com/channel/UCbtwi4wK1YXd9AyV_4UcE6g Support the channel on Patreon:patreon.com/adriansdigitalbasement -- Tools Deoxit D5:amzn.to/2VvOKy1 http://store.caig.com/s.nl/it.A/id.1602/.f O-Ring Pick Set: (I use these to lift chips off boards)amzn.to/3a9x54J Elenco Electronics LP-560 Logic Probe:amzn.to/2VrT5lW Hakko FR301 Desoldering Iron:amzn.to/2ye6xC0 Rigol DS1054Z Four Channel Oscilloscope:rigolna.com/products/digital-oscilloscopes/1000z Head Worn Magnifying Goggles / Dual Lens Flip-In Head Magnifier:amzn.to/3adRbuy TL866II Plus Chip Tester and EPROM programmer: (The MiniPro)amzn.to/2wG4tlP aliexpress.com/item/33000308958.html TS100 Soldering Iron: amzn.to/2K36dJ5 ebay.com/itm/TS100-65W-MINI-Digital-OLED-Programmable-Soldering-Iron-Anti-static-Structure/113382669853 EEVBlog 121GW Multimeter:eevblog.com/product/121gw DSLogic Basic Logic Analyzer:amzn.to/2RDSDQw ebay.com/itm/USB-Logic-DSLogic-Basic-Analyzer-16Ch-100MHz-4Ch-400MHz-Xilinx-Spartan-6-FPGA/202543965672 Magnetic Screw Holder: amzn.to/3b8LOhG harborfreight.com/4-inch-magnetic-parts-tray-90566.html Universal ZIP sockets: (clones, used on my ZIF-64 test machine)ebay.com/itm/14-16-18-20-24-28-32-40-pin-IC-Test-Universal-ZIF-Socket-Fs/303206721971 RetroTink 2X Upconverter: (to hook up something like a C64 to HDMI)http://www.retrotink.com Plato (Clone) Side Cutters: (order five)ebay.com/itm/1-2-5-10PCS-Micro-Scissor-125mm-PLATO-170-Electronics-Cutter-Side-Cutting-Pliers/163458746184 Heat Sinks:aliexpress.com/item/32537183709.html Little squeezy bottles: (available elsewhere too)amzn.to/3b8LOOI --- Links My GitHub repository:github.com/misterblack1?tab=repositories Commodore Computer Club / Vancouver, WA – Portland, OR – PDX Commodore Users Groupcommodorecomputerclub.com --- Instructional videos My video on damage-free chip removal:youtube.com/watch?v=XQVjwPsVFd8 --- Music Intro music and other tracks by: Nathan Divino @itsnathandivino

Does this dead laptop have a gas plasma display? Lets try to revive it to find out! Samsung S5200
Adrians Digital Basement 2024-01-13 | I've had this Samsung S5200 laptop kicking around the basement for a year or two now and I've always been so curious to know more about this machine. This particular specimen is dead, so trying to turn it on reveals nothing. It also seems to be totally unknown to the world with no information about it existing outside of the odd eBay listing and a single post on VCF Forums.

Restoring a Commodore 1702 monitor using a main board from 2023
Adrians Digital Basement 2024-01-06 | It's no secret that I simply love the JVC built Commodore 1702 monitor. It's a solidly built and excellent performing monitor. One thing that lets the monitor down is the fact that isn't a multi-standard monitor, meaning it only support PAL _or_ NTSC (depending on where there monitor is from.) Another common problem with these monitors is that most 1702 monitors are now nearly 40 years old, and can be quite worn out. Let's fix both of these issues by making a one of a kind multi-format and improved 1702 monitor! 0:00 Intro 2:05 Installing the new board 17:11 First power up and setup 28:10 Figuring out how to connect external video inputs and enable S-Video 38:17 Testing out Chroma-Luma input (S-Video) 42:58 Testing the tuner 45:28 Fully testing the completed monitor 56:53 Outro 1:01:29 Addendum (for analog video nerds) -- Links Replacement TV board: ($54 as of Dec 2023)aliexpress.us/item/3256805253057004.html Scanned schematics and service mode info:github.com/misterblack1/yichuang_crt_board First video using this replacement board:youtube.com/watch?v=MoqflFfvkR0 Hannover Barsen.wikipedia.org/wiki/Hanover_bars Adrian's Digital Basement Merch store:my-store-c82bd2-2.creator-spring.com Adrian's Digital Basement ][ (Second Channel)youtube.com/channel/UCbtwi4wK1YXd9AyV_4UcE6g Support the channel on Patreon:patreon.com/adriansdigitalbasement -- Tools Deoxit D5:amzn.to/2VvOKy1 http://store.caig.com/s.nl/it.A/id.1602/.f O-Ring Pick Set: (I use these to lift chips off boards)amzn.to/3a9x54J Elenco Electronics LP-560 Logic Probe:amzn.to/2VrT5lW Hakko FR301 Desoldering Iron:amzn.to/2ye6xC0 Rigol DS1054Z Four Channel Oscilloscope:rigolna.com/products/digital-oscilloscopes/1000z Head Worn Magnifying Goggles / Dual Lens Flip-In Head Magnifier:amzn.to/3adRbuy TL866II Plus Chip Tester and EPROM programmer: (The MiniPro)amzn.to/2wG4tlP aliexpress.com/item/33000308958.html TS100 Soldering Iron: amzn.to/2K36dJ5 ebay.com/itm/TS100-65W-MINI-Digital-OLED-Programmable-Soldering-Iron-Anti-static-Structure/113382669853 EEVBlog 121GW Multimeter:eevblog.com/product/121gw DSLogic Basic Logic Analyzer:amzn.to/2RDSDQw ebay.com/itm/USB-Logic-DSLogic-Basic-Analyzer-16Ch-100MHz-4Ch-400MHz-Xilinx-Spartan-6-FPGA/202543965672 Magnetic Screw Holder: amzn.to/3b8LOhG harborfreight.com/4-inch-magnetic-parts-tray-90566.html Universal ZIP sockets: (clones, used on my ZIF-64 test machine)ebay.com/itm/14-16-18-20-24-28-32-40-pin-IC-Test-Universal-ZIF-Socket-Fs/303206721971 RetroTink 2X Upconverter: (to hook up something like a C64 to HDMI)http://www.retrotink.com Plato (Clone) Side Cutters: (order five)ebay.com/itm/1-2-5-10PCS-Micro-Scissor-125mm-PLATO-170-Electronics-Cutter-Side-Cutting-Pliers/163458746184 Heat Sinks:aliexpress.com/item/32537183709.html Little squeezy bottles: (available elsewhere too)amzn.to/3b8LOOI --- Links My GitHub repository:github.com/misterblack1?tab=repositories Commodore Computer Club / Vancouver, WA – Portland, OR – PDX Commodore Users Groupcommodorecomputerclub.com --- Instructional videos My video on damage-free chip removal:youtube.com/watch?v=XQVjwPsVFd8 --- Music Intro music and other tracks by: Nathan Divino @itsnathandivino
