| Processor boards | ||||
| SBC V2 | Running | Running with no problems at 20Mhz with Prop I/O or PPISD. Built with ALS and F-logic. RomWBW 2.5.5, RomWBW 2.7.1. Up to (at least) 12MHz with DiskIO v3, Dual IDE and Dual SD. Somehow I will reach 20MHz with more boards and without intermittent errors! | ||
| Z180 Mark IV, x2 | Running | Built with LS-logic only. Z8S180-33 with 18.432MHz oscillator (x2), RomWBW 2.7.1 and UNA. Built yet another Z180 Mark IV. I love this board! Playing with RS422 | ||
| Mini-68k | Running | Alive and running at 10 MHz with MC68008FN10. LS-logic only. Tested with MF-PIC, Disk I/O V3 and Dual IDE. | ||
| Kiss-68030 | Running | Running at 25MHz. CP/M-68k and Will's Linux distro. I had problems programming the GALs (Lattice GAL22V10C and GAL22V10D). Solved with yet another programmer - a Genius G540. I quote: The Genius G540 programmer is a case of good hardware let down by its software. An effort to improve the English can be found here (not tested yet): http://www.edaboard.com/thread313237.html Updated USB-drivers for Genius G540 can be found here: https://www.silabs.com/products/interface/Pages/direct-access-drivers.aspx It's not straight forward though. I had to copy the file StgPro.inf (from the installation CD) and add it to the downloaded files to make it work. Tested with Windows XP. | ||
| SBC6120-RBC Edition | Running | Assembled one day after arrival! Beautiful! After a few weeks of too much work and other dull things to do… Playing Adventure! | ||
| CPU280, x2 | Running | I just had to build two! Thank you Lamar for reviving Tilmann Reh's fascinating (although a bit frustrating) board. | ||
| I/O Boards | ||||
| 4UART-USB | Assembled | Not tested yet | ||
| Backplane-8, x5! | Running | Sturdy, bullet-proof, reliable. | ||
| Bus Monitor | Assembled and alive | Blinkenlights! Testing and learning. This is supposed to be a useful piece of equipment. | ||
| Disk I/O V3 | Running | Built with LS logic only. Tested with Mini-68k at 10 MHz and SBC V2 at 8, 10 and 12MHz. | ||
| Prop I/O V2 | Running | Running with SBC V2 at 20 Mhz. Built with ALS logic except U3 (74LS682) and U7 (74F06). | ||
| Color VDU V2 | Assembled | Alive! No thorough testing yet. Too many toys to play with! I have a few monitors. Still hoping… | ||
| Multifunction-PIC, x2 | Running | Built two with LS-logic. One for Mini-68k and one for Kiss-68030. | ||
| Dual IDE with FDC, x2 | Running | Built two with LS-logic. Tested with Mini-68k at 10 MHz and SBC V2 at 8, 10 and 12MHz. | ||
| Dual SD | Running | Built with LS-logic. Tested with SBC V2 at 8, 10,12, 16 and 20MHz. Intermittent errors with old/slow SD-cards. Less problems with RomWBW 2.5.5 compared to 2.7.1 | ||
| Mini boards | ||||
| PPISD, x3 | Running | Tested with SBC V2 at 20 MHz and PPI CP82C55A or TMP82C55AP-10. Problems with old Lexar SD-cards but no problems at all with new 8 GB SDHC SanDisk cards. | ||
| Planned | ||||
| ECB Am9511 | Not yet | Math Coprocessor board with Am9511 at 3 or 4 MHz. Interfacing can be accomplished in several ways: memory mapped or as an IO-device - demand/wait, poll status, interrupt driven or DMA transfer. I'll go for simplicity rather than maximum performance. I suppose the Am9511 is quite useless for the Z8S18033 or MC68030 boards, but it could add some floating-point performance to a slow Z80 or a 68B09/6502. | ||
| Math look-up table | Not yet | 16-bit math look-up table. Maybe something like this: http://wilsonminesco.com/16bitMathTables/ | ||
| ISA boards Sergey's Xi 8088 | ||||
| Xi 8088 | Assembled | My digital oscilloscope shows signs of activity | ||
| ISA Backplane | Assembled | Alive | ||
| ISA SVGA PCB, x2 | Running | Tested in my 286. I have built two of them. Surface mount is easy. Just solder it! | ||
| ISA OPL2, x2 | Running | Tested with Castle Wolfenstein (286+). I hear music! | ||
| ISA Floppy Disk and Serial Controller PCB | Assembled | Alive | ||
| ISA XT-CF-Lite | Assembled | Alive | ||
| ISA XT-IDE V2, x2 | Assembled | Alive | ||
| VT100 | ||||
| Geoff Graham's ASCII VT100 Video Terminal modified, x2 | Running | I modified Geoff's excellent construction in some small details. I added yet another LED (+5V), a DC power jack, a different RCA socket, a different and less anemic 3.3V voltage regulator, jumper blocks for RGB color selection, a D-sub connector and a MAX233. I allowed the PCB to be larger (100×75 mm) and single-sided. I had to add a few wires on top. I used Geoff's software unmodified. I actually built two and bought a PICKit3 for $10, chinese copy for sure, but working! http://geoffg.net/terminal.html | ||
| Sharp MZ-series | MZ-80B, MZ-700, MZ-800 | www.sharpmz.org http://www.old-computers.com/museum/default.asp | ||
| FDC board | Some progress | FDC board based upon WD1773, for Sharp MZ-80B, MZ-700 and MZ-800 | ||
| RS232 board | Running | For Sharp MZ-800 and MZ-80B. | ||
| QuickDisk IF | Running | QuickDisk interface for Sharp MZ-800. An easy biuild, only three ICs. QuickDisks store and access data in sequence, not random access, but they are quite fast and give the user the illusion of random access. |
