Hi everybody, the recent talk about FTDI USB/RS232 chips reminded me of this... Sometime ago, I bought a numeric USB keypad with a two-line dot matrix LCD on top on a flea market. This piece of hardware is designated DATACOMP Electronics co., Ltd. Model No.: DLK18U_100AL and has a marking referring to "alphyra" (which seems to have been a now-defunct/absorbed e-payment outfit) above the display. It has 18 keys (4 blank, ESC (red key body), numeric keypad "0"-"9",".", backspace (left arrow), and Enter (green key body)) and shows, IIRC, "Version 1.0" on the display when powered. The .tw-based manufacturer is alive and even has a driver download for it, which seems to be nothing more than an FTDI serial port driver providing a new COM port on my computer. The FTDI chip inside the keypad is attached to an EN78P447xxx device, which I found out to be an OTP microcontroller. What I unfortunately wasn't able to find yet was any description how to talk to/what to expect from this port. Listening on the COM port at various speeds with the usual 8n1 parameters and pressing keys on the keypad yielded nothing, so there's probably some sort of initialization necessary. A long shot again I know, but if somebody has experience or documentation regarding this keypad that may be shared, then please contact me. Yours truly, Arno Kletzander

Emulating a long-lost portrait-display card for the PC

Tonight I tried patching support for this card into a PC emulator, and running GEM (and Windows 1) with the results. <http://www.seasip.info/Gem/History/longgem.png> - GEM/2 desktop <http://www.seasip.info/Gem/History/longwin1.png> - Windows 1.04 According to reviews, the card could also do other tricks; it could superimpose MDA-style text on the graphics output, and do a dual-head sort of display with MDA text in the top half of the monitor and CGA graphics in the bottom. But without any documentation or its DOS driver (VHRBIOS.SYS), how it did those will remain a mystery. Such information as I have managed to glean is at <http://www.seasip.info/VintagePC/mdsi_genius.html>. -- John Elliott _______________________________________________ gem-dev mailing list gem-dev at simpits.org http://www.simpits.org/mailman/listinfo/gem-dev

Wanted: video board for AlphaStation 200 4/233

by tothwolf＠concentric.net

I have an AlphaStation 200 4/233 which was given to me without a video board or floppy drive. I stuck an old Teac FD-235HF in the floppy bay to fill the hole (no data cable), but have no idea what I really need for a video board. I'm planning to use this machine as a low end testbed machine for Debian Linux since the Alpha port needs to be brought back up, so I know I probably need a board that can handle more than 256 colors. I think this eliminates the ZLXp-E1 (TGA 8-plane), but at the same time it may be a good idea to be able to test with a TGA board as well since there are going to be quite a few of these machines out there which have a TGA board. I will probably also want to run ULTRIX or OSF/1 on the machine at some point, assuming I can find installation media. Based on the datasheet I found online, these appear to have been (some?) of the video boards offered as options for this system: ZLXp-E1 8-plane PBXGA-AA PBXGA-AN [NT] ZLXp-E2 24-plane PBXGA-BA PBXGA-BN [NT] ZLXp-E3 24-plane PBXGA-CA PBXGA-CN [NT] ZLXp-L1 24-plane PBXGC-AA ZLXp-L2 24-plane PBXGC-BA Does anyone have an extra video board laying around that they would be willing to part with for postage costs? This machine has been sitting unused for far too long and I'd really like to put it to work.

To all with interest in IBM 7090

by peter＠vanpeborgh.eu

Guys, I am sending this to all who have registered an interest in the IBM 7090 and museums. Sorry if I got some people wrong! This computer started life at AWRE in the UK (nuclear weapons design?!) and finished in the Medical Computing department at Manchester Uni in 1970, where it ran for 10-20 years. It had 4 channels, 32K memory, card reader, card punch, 300 LPM barrel printer and ?20 mag tapes. It also had an IBM 1401 for printer I/O. I have now surveyed the stuff available. There is no hardware. It is a lot of (probably complete) hardware documentation, cicuit diagrams, s/w documentation (IBSYS, etc) also. Also a lot of mag tapes of mixed content and some card trays of mixed content. Are any of you out there interested? It is all quite heavy so transport will be a challenge, but surmountable! The stuff will be available in the first week of September. Any sensible offers will be considered. It might go on eBay but I will wait until you guys respond first. Kind regards, peter vp || | | | | | | | | Peter Van Peborgh 62 St Mary's Rise Writhlington Radstock Somerset BA3 3PD UK 01761 439 234 || | | | | | | | |

IBM disk

by BHuntsman＠mail2.cu-portland.edu

Anyone have about 3 or 4 or so IBM 00K4151, FRU 10L6081 9.1GB disk drives in PC Server hot swap trays (76H7287)'s (preferably with non-broken locking levers) that they'd like to part with for ~$5-$10 each? I need a few more to get my P/390 fully stocked... :) Thanks in advance!

X Window server for NEC 7220

by LYNCHAJ＠yahoo.com

Hi Does anyone know of an X Window server implementation for the NEC 7220 GDC? The chip has several names including the Intel 82720, NEC 7220A, NEC 7220D, uPD7220, uPD72020, etc. Essentially this graphics chip was the main rival to the MC6845 prior to the domination of the IBM PC architecture for microcomputers. The NEC 7220A is most notably known for the NEC APC and Epson QX-10 however was used in a number of other systems. Typically it was used for CAD type graphics and/or business graphics as its main strength was drawing primitives like lines, circles, rectangles, etc rather than BITBLT operations. I would imagine an X Window server for the NEC 7220 would suffer in comparison to today's graphics boards. However I think it would be comparable to non-accelerated VGA and/or VESA modes which both have X Window server implementations. Thanks and have a nice day! Andrew Lynch, 73 de N8VEM
