This 6502 is as old as me and I test it Adrians Digital Basement 2022-10-22 | There is a lot of argument if the missing ROR instruction is a bug or not. Whatever it is, it was clearly intended to be there but was left out at the last minute, likely due to time constraints for the release for the CPU. Just a handful of months later an updated data sheet was released saying the instruction would be added into future versions of the chip. The ROM we wrote is able to identify (in a running system) if you have a CPU that has a non-functional ROR instruction. --- InfoPossible TTL shift registerTI 1A5008--- Video LinksROM to test for the ROR bug on the Apple II:github.com/misterblack1/6502_ror_bug_testPagetable ROR bug article:pagetable.com/?p=406A viewer @DaftdogUK discovered what this is!

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 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. -- InfoHow 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. -- LinksMini Mac Repair-a-thon:Part 1: youtu.be/lHvGc4LWR0gPart 2: youtu.be/nSoSX6XV7t4Part 3: youtu.be/xx08YXkUOnQRecapping the Mac Classic II Motherboardyoutu.be/rpVAg6hG__YPrevious Mac Repair-a-thon from 2020:Part 1: youtu.be/lKD65I86XGQPart 2: youtu.be/kNhVQWH318MPart 3: youtu.be/uatqcZRzmt0Part 4: youtu.be/zC0qi5dQsWsPart 4.5: youtu.be/YikOY8WTnLUPart 5: youtu.be/PHTnauC020oPart 6: youtu.be/mqWCPkfcr1AAdrian's Digital Basement Merch store:my-store-c82bd2-2.creator-spring.comAdrian's Digital Basement ][ (Second Channel)youtube.com/channel/UCbtwi4wK1YXd9AyV_4UcE6gSupport the channel on Patreon:patreon.com/adriansdigitalbasement-- ToolsDeoxit D5:amzn.to/2VvOKy1http://store.caig.com/s.nl/it.A/id.1602/.fO-Ring Pick Set: (I use these to lift chips off boards)amzn.to/3a9x54JElenco Electronics LP-560 Logic Probe:amzn.to/2VrT5lWHakko FR301 Desoldering Iron:amzn.to/2ye6xC0Rigol DS1054Z Four Channel Oscilloscope:rigolna.com/products/digital-oscilloscopes/1000zHead Worn Magnifying Goggles / Dual Lens Flip-In Head Magnifier:amzn.to/3adRbuyTL866II Plus Chip Tester and EPROM programmer: (The MiniPro)amzn.to/2wG4tlPaliexpress.com/item/33000308958.htmlTS100 Soldering Iron: amzn.to/2K36dJ5ebay.com/itm/TS100-65W-MINI-Digital-OLED-Programmable-Soldering-Iron-Anti-static-Structure/113382669853EEVBlog 121GW Multimeter:eevblog.com/product/121gwDSLogic Basic Logic Analyzer:amzn.to/2RDSDQwebay.com/itm/USB-Logic-DSLogic-Basic-Analyzer-16Ch-100MHz-4Ch-400MHz-Xilinx-Spartan-6-FPGA/202543965672Magnetic Screw Holder: amzn.to/3b8LOhGharborfreight.com/4-inch-magnetic-parts-tray-90566.htmlUniversal 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/303206721971RetroTink 2X Upconverter: (to hook up something like a C64 to HDMI)http://www.retrotink.comPlato (Clone) Side Cutters: (order five)ebay.com/itm/1-2-5-10PCS-Micro-Scissor-125mm-PLATO-170-Electronics-Cutter-Side-Cutting-Pliers/163458746184Heat Sinks:aliexpress.com/item/32537183709.htmlLittle squeezy bottles: (available elsewhere too)amzn.to/3b8LOOI--- LinksMy GitHub repository:github.com/misterblack1?tab=repositoriesCommodore Computer Club / Vancouver, WA – Portland, OR – PDX Commodore Users Groupcommodorecomputerclub.com--- Instructional videosMy video on damage-free chip removal:youtube.com/watch?v=XQVjwPsVFd8--- MusicIntro 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. Let's see if I can revive the machine so it can reveal some of its secrets.

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.)
