This is the at top of my list. It's going to be a USB-2 channel driver (talks to peripherals). Have the design done but have't started building it. Immediate goal is testing of channel interfaced devices to help cull the collection of big iron, secondary goal is operation of the devices from Hercules. Speaking of USB-to-X interfaces, where X is pecular, thanks, Sellam for the plug for my USB-to-Documation interface. I'm thinking of building two more copies, another for me and another for the museum. Is anyone else interested in one? If so I'll do up a PC board instead of wire-wrapping, and we can share the production cost. Let me know by private email. PS - APL\1130 was mentioned recently. We have the source on punched cards. I've read it in but there were a couple of errors which is why it's not published on ibm1130.org yet. Also, it appears to have been modified (slightly) to run on the IBM 1800. brian =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- _| _| _| Brian Knittel _| _| _| Quarterbyte Systems, Inc. _| _| _| Tel: 1-510-559-7930 _| _| _| Fax: 1-510-525-6889 _| _| _| Email: brian at quarterbyte.com _| _| _| http://www.quarterbyte.com
