I used a Hitype I with 12 bit OEM interface and a 2P+S S100 card back in the day. Since every bit of movement was under control of the program driving the interface, you could do not only PS with bidirectional "smart" positioning, but also plotting. I probably have my drivers for 8080 on an 8" disk somewhere. ISTR after nearly 50 years, that the movement granularity was about 1/48 of an inch. The power supply for that thing was separate and had 3 noisy fans. After the success of the Diablo Hitype models, other outfits had similar products. I think I have one of NEC Spinwriters tucked away somewhere, which used not a typewheel, but cup-shaped "thimble". Early one, Qume was a major competitor of Diablo--no surprise, since a fair number of the original staff fled Diablo after the Xerox purchase. Of course, daisywheel technology took over the typewriter market after the original patents had lapsed. IBM used them extensively on their typewriters, as did Brother. "Fully formed characters" as opposed to dot-matrix was a big thing back then. --Chuck
Re: how to make use of daisy wheel printer
Some characters that might not otherwise be available could be done with over-strike, such as an accent mark (When you apply for a job, do you send a RESUME?") or the tilde over N (There is an exit off of 280 that is incorrectly labelled "LA CANADA road") The en~e character is recognized as a normal letter in Spanish. Although there isn't a LOT of use for it, overstrike with hyphens is sometimes used to indicate an informal edit or redaction. Some daisy wheel printers, even some models of HiType I, such as DTC-300, had micro-spacing. Besides PROPORTIONAL spacing, You could print a period, move a TINY amount, print another period, and be able to draw or plot. (Or would that be PLOD? And you thought that a Calcomp Plodder was slow!)) Some daisy wheels had reinfoced period, underline and hyphen to prevent premature wear. Wordstar had some "drivers" for proportional spacing. I kinda doubt that there are practical Windoze drivers. -- Grumpy Ol' Fred ci...@xenosoft.com On Sat, 29 May 2021, Christian Groessler via cctalk wrote: Hi all, what are the word processing options for a daisy wheel printer?

Re: COMPAQ ISA PC to ethernent
Randy, I'm a little late to the party, but to get a Compaq connected to Ethernet look for the following: - 8 bit: NE1000, 3Com 3C503, WD or SMC 8003 series -16 bit in an 8 bit slot: Some NE2000 clones, Intel 8/16 - 16 bit cards: many choices There are a lot of choices for networking code, but a lot of it is old and out of date. (FTP clients that don't support PASSIVE connections are not terribly useful anymore.) I wrote (and still maintain) mTCP ( http://www.brutman.com/mTCP/mTCP.html) which gives you the following: DHCP, Ping, Netcat (TCP only), an IRC client, an FTP client, an FTP server, a Simple NTP client, a Telnet client, etc. All of this is supported and runs well on 8088 class machines. mTCP uses the packet driver specification to talk to the Ethernet card, so the card has to have an appropriate driver. (There are shims that allow you to use ODI drivers and packet drivers that fake Ethernet over SLIP or PPP.) Mike
H960 documentation
So, I have images of two different pieces of DEC documentation for the H960 series of racks/cabinets (the H950 is the bare rack; the H960 is the rack complete with various appurtenances such as side panel, stabilizer feet, etc). I had a request for them, so I've put them online. They are: http://ana-3.lcs.mit.edu/~jnc/tech/H960/DEC_cabinets1.jpg http://ana-3.lcs.mit.edu/~jnc/tech/H960/DEC_cabinets2.jpg The entry in the Direct Sales Catalog which covers them; includes illustrated breakdowns, and the DEC part numbers for everything. http://ana-3.lcs.mit.edu/~jnc/tech/H960/DECRackManual1.jpg http://ana-3.lcs.mit.edu/~jnc/tech/H960/DECRackManual2.jpg http://ana-3.lcs.mit.edu/~jnc/tech/H960/DECRackManual3.jpg http://ana-3.lcs.mit.edu/~jnc/tech/H960/DECRackManual4.jpg http://ana-3.lcs.mit.edu/~jnc/tech/H960/DECRackManual5.jpg The Assembly Guide; it shows in detail how all the bits go together (includes all the captive nuts, bolts, etc).
